Something about steel vacuum coating

With vacuum technology and materials technology development and the development of new iron and steel industry an urgent requirement of steel, strip steel strip vacuum coating surface treatment is becoming an important technology, with good prospects for development. At present, become mature and can quickly realize the industrialization of the strip electron beam vacuum coating technology is the steel vacuum coating. Practice has proved that steel vacuum electron beam coating has many advantages: (1) choice of coating material melting point without much restriction. High energy density electron beam can make the coating material in a very short time to reach 3000 ℃ ~ 6000 ℃. Therefore, in addition to common galvanized hot dip galvanized, aluminum, tin, zinc oxide, almost all of the metal materials can be deposited, but also a wide variety of plated metal nitride film, metal oxide film and metal carbide and a variety of composite membrane . This strip material for the development of new offers great freedom. (2) coating of high material utilization, environmental pollution. Vacuum coating is a dry coating, no harmful liquids, gases. (3) strip coating quality, access to uniform, smooth and very thin coating, coating of high purity, corrosion resistance and adhesion. Strip coating by electron beam warm-up prior to surface activation, coating of high purity, no intermediate brittle alloy layer can be a metal forming, and even rolled into a small tube rather than directly by the coating off. (4) process flexible, easy to change varieties, according to product requirements to achieve a flexible steel plating on single-sided, double-sided, single layer, multilayer, plated two materials can reach plated mixed film. Coating thickness is easy to control, and ultra-thin films can be coated.
However, the strip is still in the vacuum coating the whole early stages of development, the share of the strip surface is still far and hot-dip, plating compared. Hinder the development of vacuum coating strip is mainly due to low productivity, high cost. The most effective solution is developed high-speed, high power and stable evaporation source.
The development of high-power electron gun and vacuum coating with a strip of key technologies. General vacuum evaporation coating resistance heating can be used and induction heating. Its equipment is relatively simple, but the heating temperature and the evaporation rate is low. Industrial production to meet the continuous need for vacuum coating steel strip, you must use heating speed, high melting temperature of the heat source. Home and abroad proved that high-power electron gun belt continuous vacuum coating process is the ideal heat source. This is because (1) electron gun emitted after electron beam can be achieved by focusing a high energy density, bombardment crucible coating material titanium dioxide, so the temperature can reach 3000 ℃ or more, than the high temperature arc. (2) electron beam energy conversion rate of 80% -90%, using the magnetic deflection system can be easily e-beam focusing and scanning, uniform heating. (3) electron beam bombardment only the surface coating material, not because of the incorporation of other materials caused by mixed problems. (4) use of the electron gun beam diameter, electric power, plus beam voltage, scan path, frequency and other parameters are easy to implement regulation. (5) use an electron gun can also be coated in the production process of steel-plated steel vacuum was warm, clean and strip electron gun is used, to bombard the surface activation. Stop by the electron beam scanning, strip surface temperature at 200 ~ 550 ℃, the steel coating and preheating is necessary to improve coating adhesion.

The development of green packaging about environmental protection

With the rapid development of global economy and rising standards of living, solid waste and pollution damage to the environment and waste of resources on the Earth facing the international community today is the major environmental problems. UNEP has been put the solid waste disposal as major global environmental issues. And packaging waste is an important component of solid waste, is becoming increasingly clear recognition of its environmental hazards, so the packaging green packaging has become the study of development.
In addition, as human environmental awareness, thinking, values and consumer attitudes are also changing with the times of development. In business dealings, people buy goods, pay more attention to product environmental standards, which appeared in green vegetables, green food, green cars, green refrigerator, environmental clothing, and green packaging nonwoven bags and so on. It can be said that with the development of world economic integration process, in the 21st century will be a variety of fields of green products on every aspect of people's environmental protection and improve their quality of life requires further improvement of green products must have a corresponding adapt to the green packaging, in order to form a complete real green goods.
In addition, with the development of industrial modernization over to grab the earth and human resources, global environment is deteriorating, various countries and regions in order to protect land resources and environmental quality and human economic interests of their own, a series of environmental treaties and agreements have been have been developed. According to the WTO survey showed that more than 150 existing multilateral environmental agreements, which contain a considerable part of the terms of trade, but also set up a WTO Trade and Environment Committee, to deal specifically with issues related to trade and the environment. Can be said that environmental issues will be the 21st century international economic and trade cooperation, the main problem, so the development of green packaging will be increasingly important.
To reduce waste of resources, the task of protecting the environment, the packaging industry must embrace innovative ideas, and strengthen environmental awareness. In the study of new packaging materials, new packaging technology, design new packaging products reusable bag and develop new standards, new regulations, consideration should be focused on the development of reduced resource consumption and waste emissions, easy recycling, self-degradation of green packaging.
Therefore, green packaging, also known as eco-friendly packaging, which not only plays the conservation, protection, indicating that the contents of information, easy identification and promotion of traditional functions, the role should have the following three aspects: (1) packed in the core of economic development nature; (2) Packaging assume environmental responsibility; (3) packaging in its efforts to improve the living conditions of innovation (from the "present and future packaging"). In 1996, IPC'96 International Packaging Symposium Conference identified the packaging waste processing 3R principle that Reduce (reduce), Reuse (reuse), Recycle (recycling). Specifically interpreted as (1) to reduce the number of used packaging and materials consumption; (2) the technical and economic conditions, the priority can be re-used packaging; (3) the development of recyclable packaging, recycling methods do not pollute the environment , but also other renewable energy.

China low-E glass technology reaches the advanced world level

China's national economy and social development plan says that: China is about to save energy resources, protecting the environment and improve product quality. Meanwhile, it will vigorously develop new energy-saving environmental building materials, insulation materials and recycling decoration magnesia materials. Currently, the penetration of China's best low-E glass with energy-saving effect is only 7%.There is a large gap between the 80% penetration of European and American countries and China’s. In support of national policy, the deep processing of the energy saving technology will has great developments.

At present, China has successfully developed China's first off-line Low-E with independent intellectual property rights coating glass production equipment, and glass by the China National Quality Supervision and Inspection Center, all meet the standards of the technical indicators, and even reached the international advanced level. This technology not only to break dependence on imported products, and promote low-E glass in China's rapid spread, energy-saving emission reduction policies in China contribute to the implementation.

Low-E glass is the best thermal insulation, energy-saving effect of the most significant technology products, single-chip low-E glass than ordinary glass, more than 30% energy saving, low-E coated glass, plus a single monolithic general synthesis of hollow glass energy saving of 50% or more. In addition, China has completed before the end of 2011 commercial solar photovoltaic TCO coating process equipment installation and commissioning, and as a basis for further accelerate solar photovoltaic equipment, the localization process. Also, all low-E glass and solar photovoltaic nickel oxide coatings must be tempered glass, high-strength security technology to meet the standards, therefore, low-E coated glass and photovoltaic will further promote the rapid development of appropriate technical equipment, high-end steel needs.

In future, with the advantage of tempered glass and the existing production equipment to, China will further integrate the resources and increase R & D and investment of energy-coated glass and equipment with high technology. The new products will constantly meet domestic market demand. China will continuous expand the international market and increase exports of energy-efficient glass and equipment. This will form three-pillar strong future prospects of solar photovoltaic technology industry, low-E glass technology industry and the world's leading high-strength safety glass technology industry. The future of China low-E glass technology is bright. Source:http://www.mhcocm.com

Ultra-thin plastic bags still exist

In many supermarkets, shopping malls and markets, there are not many people bringing their own recycle PET bag. Most people still use plastic bags. In farmers market, the bundles of ultra-thin plastic bags are still on the sale. Some environmentalists said that: In this several years, the implementation progress of ‘plastic limit’ can make people optimistic.

After the implementation of plastic limit on June 1, 2008, the supermarkets, shopping malls, markets and other retail establishments no longer provide free plastic shopping bags. The consumers must pay for them and less than 0.025 mm thick plastic shopping bags are banned to produce, sale and use. However, during the past few years, go to the mall, supermarket shopping habits to develop their own shopping bags with the proportion of people are still not high. In major shopping malls, shopping bags placed on the shelves at the checkout, very few consumers stop to concern buyers is very few. On the contrary, many customers still prefer to spend a few cents to buy a plastic bag. A customer said, use plastic bags from free to fee, ‘plastic limit’ to benefit the business, he believes that business for the implementation of non woven bag china to use, fully able to take consumers more willing to accept the practice, such as conducting consumer integration services such as gift bags.

Plastic bags to bring convenience to people's lives, but mostly with non-renewable degradable plastic materials production, processing can only be digging these white trash landfill or high temperature incineration, and the two approaches are not conducive to environmental protection. According to scientists, test, plastic bags is difficult to degrade, buried in the ground and need 400 to 1,000 years to decay, and serious pollution of the soil, and burning of the harmful smoke and toxic gas, it will also result in atmospheric pollution. Caused by heavy use of plastic bags white pollution, plastic bags, it is called as the worst invention of the 20th century.

The theme of world environment day is ‘to reduce pollution, action now.’ Environmentalists propose that: to reduce environmental pollution, the general public should increase the awareness of environmental protection. They have to start actions from their own, such as try to do the common things: do reduce the use of plastic bags or never use the plastic bags. Source:http://www.cnmhc.com

Critical technology of steel vacuum coating

With the developments of vacuum technology and materials technology and the urgent requirement for developing new steels, steel vacuum coating is becoming an important technology in surface treatment.

Companies should not produce more bags blindly

The implementation of plastic limits pushes non-woven industry producing the recycling bags to the limelight. The hot selling of recycle bags makes many companies understood the fancy business opportunities. It is estimates by the relevant departments that Chinese supermarkets use 10 million plastic shopping bags every day. The amount of other types of plastic bags is two billion or more. After reusable shopping bags being used, the annual demand is expected to reach ten billion.

Chinese textile industry association mentions that, the plastic limit can at least make the green bag sales increased one percent. However, due to overly optimistic investors expected, the momentum of overheated investment also highlights: the existing production capacity has reached 1.02 million tons, but only 70% operating rate, that is, 30% of the production line is idle.

Since the implementation of the plastic limit, the proportion of plastic waste reduced from 16.1% to 13.5%. Use less plastic bags, and bags usher in opportunities. China Textiles Industry Association branch official said, a conservative estimate, the plastic limit the sales of non-woven bags increased by at least one percent.

A general manager of non-woven products Mr. Gao says, the production of raw materials, non-woven shopping bags shopping bags also finished processing. This year's output will increase about 3 times, add $ 700 million. Because of the substantial increase in production, companies will increase more than 100 production facilities.

At present, many Chinese manufacturers’ plans to move to the production of non-woven bags, many manufacturers of the equipment have been ordered or signed reusable bag supply contract. In addition, the industry and companies planning to expand outside the industry, competition on the production line of bags of boom and in China.

The annual production of Chinese reusable bag reaches 70 million tons, ranking first in the world. On the other hand, the industry's production situation is not very good. From the analysis of supply and demand, the industry's operating rate is only 70% of equipment capacity. It means that there is 30% of production capacity which is not being operated. Presumably, the idle capacity of 300,000 tons is roughly equivalent to China's demand for non-woven bags. Source:http://www.cnmhc.com

Low-temperature pump in the optical coating application

Now the processes of optical film processing and manufacturing become increasingly complex. In order to meet production and quality of coating, a large number of thorny problems need to be resolved. From leaning and preparation of the substrate to final inspection and testing, the hardest process is the coating process.

Diffusion pump has been used in optical coating neodymium fluoride industry for 30 years, many people used to it. With the coating quality requirements, the need for better vacuum equipment. With the cryogenic pump, it can provide clean, oil-free vacuum; Not only that, even in the personnel operating errors, power outages and equipment failure, the chamber and machined parts will not be contaminated. This diffusion pumps system failure in stark contrast. If the above diffusion pumps system failure, the need for disassembly, cleaning, reassembly, leak detection and process re-inspection process. Sudden vacuum failure, the conventional treatment takes several days to a week's time.

Cryogenic pump their own gas hold: there is no low-temperature heat pump components to cause deflation, nor will the thermal decomposition of water vapor into hydrogen and oxygen or methane. And, because there is no fluid, moving parts or seals exposed to vacuum, so the corrosion, pollution and other faults are not.

Large cryogenic pumping speed, shorten the coating cycle, to increase production. The only exposed at low temperature in a vacuum pump system is the low- temperature condensation on the surface plate, it can keep the temperature low enough to allow the coating chamber and condensing the gas into the cryogenic pump all. Cryogenic pump provides high pumping speed for water without any liquid nitrogen. Cryopump pumping speed ratio of the other gases in liquid nitrogen cold trap of the same size / diffusion pump combination of about 50% higher to 100%. The increase in pumping speed on the mean in a very short period of time can achieve the required vacuum, but in the process under the same conditions can make such as the reaction of hydrogen and oxygen gas partial pressure by 50% or more.

Cryogenic vacuum pump to provide high-quality coating products to increase production and quality. Previously, when the company's coated with oil diffusion pump, due to mainly the adhesion and hardness tests to 5lOmm and 32-inch (810mm) of the secondary coating chamber were 1 / 8 and 1 / 10, and After installing the pump in the secondary use of low-temperature coating rate of 0. The use of low-temperature production of the film after the pump intensity, solid, and has good abrasion resistance.

Even with the best most expensive synthetic oil diffusion pump, the vacuum chamber using high pressure switch, but also the need to prevent low-back pump oil: oil migration to the substrate or the internal cavity wall and the barium titanate surface and where the aggregate. Thus, with a second coating of the pollutants released by outgassing into the chamber again. Cavity becomes more and more dirty, resulting in adhesion and pinhole problems making production decreases. Closest to the pollution of the cavity wall of the optical coating suffered the greatest impact. Replaced by low-temperature back to the oil pump after eliminating pollution.

Low voltage pump will not reduce short-term or expensive power and makes the coating layer is damaged. Cryogenic pumps can rely on its low-temperature environment to maintain its power vacuum and to continue pumping in 10-20 minutes. This circuit breaker has been reset long enough time, and can save the production of potentially dangerous. Under normal use, low-temperature long-running pumps and compressors should be 20,000 to 30,000 hours without checking. Some users of the pump in the absence of any examination in the case have been running for 60,000 hours or longer. Regular maintenance is the main l million per hour to run the compressor unit to replace less expensive adsorber. In addition, because the pump is a low-temperature adsorption trap pump, and the cavity is used to condense and store the gas, so periodic regeneration is necessary, this is a very simple approach, can be generally accepted.

Cryopump regeneration need not be very frequent. A 48-inch vacuum chamber of the coating equipment, coating operation when the rotation of two classes, and class coating 12 times, only about every two required 120 coated with or after regeneration. Of course, in extreme conditions, very frequent regeneration may be necessary. For example, in the case of high water vapor loads in four layers of plastic film coated on a substrate, a 30-minute cycle time, plating 32 times per day, yield more than 38,000.

It is better to do the work with planning. The regeneration can be made on a regular basis which is convenient for the users. The typically situation is operating the machine on weekends without the human care. Even with a microprocessor controlled automatic regeneration system to complete the regeneration without the interference of producing. It is complete without a human’s help from the separation of the pump, shutting down, purification, heating and re-starting to run rough pumping. Many low-temperature pump users arrange the regeneration in early Monday morning so that the system is ready for the timing of the first use. In some cases, two cryogenic pumps can be use for recycling at the same time. Source:http://www.mhcocm.com

Recycle bags are not just for meeting the plastic limits

Now many consumers are still customary to use supermarket plastic bags. Among them, most are the young people. Over half of the consumers use their own recycling bag while there are many consumers use hands as the “shopping bags”. Before the plastic limit, the customers with bringing their own shopping bags just accounted for less than twenty percent and the phenomenon of requiring more plastic bags is common. Consumers think that is a benefit. Their excuse for more plastic bags it that they have not enough bags. Somebody come with bags obviously but still require the free bag.

But in most bazaars, all kinds of plastic bags are still open to a large number of unqualified provided free of charge to consumers, the situation with the plastic limit before the commencement of any different. Almost all of the stall owners are no signs of using a variety of thin plastic bags, and all is free. Plastic limit makes a lot of businesses reluctant to use these bags. But the loud objections of consumers, taking into account the vegetables a couple of dollars a dime bag also charge the money to do some reluctance, plus on the investigation do not strictly relevant. So everyone will secretly return to the previous state.

The prevailing myth is that plastic shopping bags and food packaging bags confused. In fact the plastic limits the shopping bags. Meat market should used food bags which have no requirements in thickness. It is asked to provider consumers free bags. Meat market but there is few qualified to provide food bags, the basic shopping bags instead of plastic. It is neither health nor security but expressly prohibited.

Beginning last year, once red-hot market will go up the bags downhill. At the end of 2007 may be introduced by the state, plastic limit news of the rapid expansion of the industry, only one place in Guangzhou bags less than 10 enterprises from the rapid expansion to nearly one hundred. Influx of a large number of companies led directly to price competition, falling profits, gross margin is now a green bag only one two cents. Especially the financial crisis, most commercial companies are reducing marketing, and promotional activities together with the delivery of the bags also will decline in sales. The more important reason is that the ‘plastic limit’ since its implementation, failure is still a large number of plastic bags in circulation, making the bags difficult to open a sales situation.

China launched the world's first plastic limit. It shows that the Chinese government's concern for environmental issues. And in the past year, plastic limit does change Chinese people's dependence on plastic bags a lot and spreads the environmental awareness. It does help reduce plastic bag caused by the white pollution, which is a welcome aspect. But, on the whole, a large number of non-compliance still exists in a plastic bag on the market. The quality supervision department did not control the source from the production, resulting in these plastic bags are still flooding into the market. In circulation, regulation of the business sector also in place, especially in some of the meat market, substandard plastic bags are still dominant.

Chinese quality supervision departments should strengthen the supervision of plastic products manufacturers and prevent the source of plastic bags. The business sector should actively combat illegal use of plastic bags in meat market. Meanwhile, all departments of China should strengthen the environmental advocacy in the whole society and make people accepted rept bag in their deep minds. It is not just for meeting the temporary plastic limits. Source: http://www.cnmhc.com

Development of electron-beam steel coating technology

The application of vacuum coating technology in steel strip surface treatment provides a new means for the development of new strip materials and an important technology of steel industry’s sustainable development.

The vacuum coating is evaporating the metal and other solid materials and forming a plating layer film on the surface of the deposition in the situation of gasification and vacuum. Most representative of the vacuum coating method is the resistance heating and electron gun heating. The former is the high melting point metal such as tungsten, etc. around the spiral shape, made resistance heater, power and Joule heat generated by the coating material to be placed in which the heating and evaporation. The latter is the use of electron gun heated coating material directly from the electron gun out of the electron beam in a magnetic field, guided by their bombardment coating material so that heat evaporation. More advanced vacuum coating is plasma vacuum coating, coating materials, evaporation, and then plasma gasification technology. After the plasma of particles can be applied to obtain very high voltage, etc. It is easy to form a dense, strong adhesion of the film.

Strip vacuum coating vacuum coating and the general difference is that it is a large area continuous coating process, the efficiency of the coating magnesia material evaporation, evaporation of the stability of the long, large-area uniformity of the coating with very high demands.

More mature, easy-to-strip method is to promote the electron beam coating technology. Abroad from the fifties of last century began the development of the technology developed. Among them, the power strip evaporation source is the key in the vacuum coating technology. With the electro-physical technology, high-power electron gun has been developed and applied, makes this technology from the laboratory to industrial production. Practice has proved that electron beam heating vacuum evaporation coating process for steel strip with a high energy density, high evaporation rates and high energy conversion rate of technological advantage.

The general vacuum strip coating process is: first strip in the atmosphere after cleaning, then into the vacuum decompression chamber, the electron gun warmed up, the coating material molecules or atoms deposited on the surface of the strip walking on the coating layer formed by the cooling. Strip back into the atmosphere via pressurized chamber, which is continuous to the air-to-air vacuum coating. In this process the key technologies are: vacuum conditions, using the electron gun emits a high energy density of the electron beam crucible coating material, the material melted, the vaporization of atoms, molecules into a certain amount of evaporation rate and the vapor pressure of the vapor cloud, set along a certain direction, the surface of the strip on the warm-up and activation, even after cooling to form a solid coating material layer.

At present, the international use of electron beam coating technology strip width of 1.25 meters, strip thickness of 1.2 mm, the electron gun power of 1,500 kilowatts, the maximum coating speed can reach 200 meters per minute, coating nickel oxide materials are also limited from the start aluminum, developed to be copper, nickel, titanium, chromium, stainless steel and other materials. in the late 1980s in China, East Germany first introduced the original design and production of EBA-300 type electron beam coating steel strip production line, this is a from the atmosphere into the atmosphere, including the pre-treatment units and the full continuous production line. Performance is now able to produce good quality, reasonable price, welcome to the steel strip coating by the user of new products.

At present, e-beam steel coating technology in China is still in its infancy. But considering from technology mastering, product quality and the demand of product number and variety from the users after introduction of the first production line, it is very promising. It is foreseeable that China steel electron beam coating technology will go towards the direction of high-power, wide format, high production and many varieties.Source:http://www.mhcocm.com

The process and performance of non woven bags

After the plastic limits introduced, many people are looking for something to replace plastic bags. Non woven bags, paper bags and other reusable bags have become the focus. But in the production process of paper bags, because of the pollution, destruction on ecological environment, it can not be the best alternative. Non-woven fabrics with a short process, high yield, fast-changing varieties, wide range of raw materials sources, long life and automatic degradation. are recognized as the best alternative to plastic bags. Experts estimate that non-woven shopping bags can be reused 10 times. The pollution is only 10% of plastic bags after abandon. Thus the recycling bags have a broad market prospect.

Non-woven bags’ price is higher than the price of free use plastic bags. Generally every one is 3 to 4 RMB. It has been sold for 15RM. Bag price is determined by its cost of production. Non-woven fabric is a non-woven fabric, it is the direct use of polymer slices, short fibers or filaments formed by various methods of fiber network formation and consolidation of technology with soft, breathable and planar structure of the new fiber products. Non-woven bags with a short process, high yield, low cost, rapid changes in varieties, wide range of sources of raw materials and so on.

Nonwoven bag is a green product with attractive appearance and low price. It is the best choice for shopping and corporate image advertising Non-woven bags made tape stable, non-toxic, no odor, does not irritate the skin, good air permeability, easy to maintain a dry cloth. Non-woven bags cheap, environmentally friendly and practical, widely used, a prominent advertising space for trade fairs and exhibitions all kinds of business activities, enterprises and institutions is an ideal promotional gifts.

Non-woven bags are divided into non-woven shopping bags, woven bags, woven advertising bags, woven tote, woven suit cover, non-woven apron, non-woven bags, and gift bags and so on. Production can be used for advertising, packaging, shopping bags, exhibition and other non-woven bags jaw domain is a green product, tenacious durable, attractive appearance, good ventilation, reusable, washable, can be screen advertising, logos, use long period, suitable for any company in any industry as advertising, gift purposes. Consumers get fine non-woven bags and businesses get the invisible advertising. It is best for both sides, so the non-woven fabrics in the market become more and more popular.

The situation and development trend of China building coated glass

Since the reform and opening-up, China's construction industry has developed rapidly. The performance demand of glass has become much serious. It evolves from the common plate glass to low-E coated hollow glass, or even amorphous silicon thin film photovoltaic glass. In functional development of building glass, coating technology has played a key role. It can effectively improve glass, light, heat, power control and realize the composite function of the glass.

Architectural glass coating production status: The current construction coated glass manufacturing enterprises, the products of many types and methods, quality and size is also uneven. According to statistics, the use of vacuum evaporation coating or sol-gel coated glass coating technology to produce about 270 more than the small producers, the main product is the single hot mirror with a reflective film or commercial, the main target is the rural and township , there are some small cities for building and decoration. The use of Chinese vacuum magnetron coating equipment and technology to produce more than 180 companies around the device, mostly from Beijing, Qinhuangdao, Guangdong and other places, equipment assembly from 20 million to 4 million to 500 million range, large-scale factory small, the main products are magnetic heat-reflective coated glass and art glass decoration with coating, product quality compared to the vacuum evaporation coating and sol-gel coated glass is much better, the individual production of heat-reflective coating quality and species can be comparable to imported products zinc oxide, such as gold heat reflective coating and magnetron art mirror and so on.

At present, China has about off-line Low-E coating 35 production lines, production capacity of about 28 million square meters, under construction or planned off-line on the Low-E coating line is expected around the 20, 2010 Low-domestic E coating capacity of 5,000 million square meters. CVD method or a PCVD method using online Low-E coated glass production companies there are three, large production capacity and quality to be further improved. Low-E coating off the equipment used can be divided into four categories. First, the full introduction of foreign advanced Low-E product line, the second is the introduction of foreign key component along the lines of foreign equipment, assembly lines and the third is in the original import of heat-reflective product line based on the transformation of production Low-E, four in the digestion and absorption of advanced Low -E production line processing and production technology, based on independent innovation, manufacturing Low-E product line.

Overall, the present glass deep-processing companies have recognized that the future market for energy efficiency and renewable energy needs and the development of coated products, is for their own economic capacity and features to challenge the industrial structure, to purchase advanced production lines, to buy Chinese Domestic production line and coating equipment manufacturers to cooperate on the line, purchased hot workability or Low-E coated products can be purchased off-site co-film coated glass and other means to achieve to meet the market demand and development. The glass deep-processing enterprises are in a good trend, increasing technological content of products, quality, continuous improvement, increasing scale. However, some manufacturers’ instant success, and some through the use of high heat-reflective coated glass Low-E coated glass, posing, and some Low-E glass, inconsistent quality, technology, however, the quality of accident frequency, to a certain extent, affected the plating film industry as a whole. As the coating industry to improve product quality awareness and quality of attention, will gradually eliminate some outdated facilities, poor quality of the Low-E coated glass manufacturer.

With the global economy booming and the general improvement of living standards, increasing energy demand, energy crisis, more and more prominent, the stage of the energy shortage has occurred. National competition for energy, friction, development of new energy and energy saving technology development and use of more and more attention around the world, energy conservation and renewable energy sources to create a consensus around the world.

Paper bags become a popular trend

Today, the use of plastic bags greatly reduces. As alternative, ‘non-woven bags’ being promoted as the green, environmental protection, pollution-free bags and are popular between all kinds of people. It is almost a synonymous of green. But with the recent remark ‘non-woven bags are not environmentally friendly’ published, misreading sparked on the non-woven bags cause people’s deep thinking.

Non-woven bags are not environmentally friendly bags. In fact, they are also plastic products. Its load-bearing, strength, and not a plastic bag, plastic bags larger than the potential crisis, more than a plastic bag waste oil. For a time, ‘woven’seems to be abuse of the environmental protection concept of the ‘scapegoat’ and let the people has re-looked at it in the eyes of science. What is the real green alternative to shopping bags? How can the concept of comprehensive environmental awareness, environmental awareness. Many people believe that non-woven bags beautiful, cheap, strong, recognized it as a substitute for plastic bags. As the business of publicity, most people think that the non-woven bags are environmentally friendly. The bags can not be washed, stained with oil thrown away, because it is environmentally friendly bags, it will not pollute the environment.

Non-woven bags are environmentally friendly, mainly to see the material is not biodegradable. Most on the market today are non-woven polypropylene bags, made of polyester, these two are non-degradable fibers, made of non-woven bags is not environmentally friendly, and its waste in the natural environment is difficult to degrade.

A professional says that, like most of the manufacturers and the industry, the main material of their rept bag is polypropylene. Production process is high temperature melting, spinning, shop classes, hot take-up of production from such steps, because the appearance of a cloth and some performance called cloth. Decomposition of this material requires harsh conditions, such as strong sunlight exposure, and under natural conditions in the room you need seven or eight years time to decompose. "From this perspective, non-woven bags can not be called absolutely environmentally friendly, but it is environmentally friendly compared to plastic or to much."

This is mainly because the manufacturers claim a recycling of non-woven bags, which is the reason for countries to implement non-woven bags. Public use ten times, twenty times and then throw away non-woven bags, would surely be lost once the plastic bag with a much more environmentally friendly. From the material perspective, plastic bags, woven bags not be completely environmentally friendly shopping bag alternatives, real alternatives to what is it?

Of course, there are also completely biodegradable alternatives, such as polylactic acid fiber, is an extract from the grain of ecological sustainable development of fiber, can be 100% biodegradable. But made of plastic, the cost of at least three times higher than the non-woven bags, it is difficult to promote. There are some tourist cities hit 'green card', is pursuing such a shopping bag, such as Yunnan, some of the area, which this paper is to promote a useful attempt. Many environmentalists have praised the final paper shopping bags as an alternative. We can learn from foreign experience, promote the use of strong paper bag shopping.

With the Chinese people's quality of life and enhance environmental awareness, in the purchase of goods green concept continue to strengthen. From pollution-free green to phosphate-free non-toxic green washing powder, from the ‘energy efficient’ green battery to the eye safe green TV green under the banner of all-pervasive, cater to consumer’s desire for health psychology.

Many environmentalists believe that the perfect state environmental certification standards and environmental protection against the concept of environmental protection supervision is the key to the abuse. About non woven bag China environmental certification, experts mentioned, China is still no national standards for environmental protection non-woven bags. Introduction of national standards for shopping bags will be given to the environmental certification standard, so that those who have not been detected in non-woven bags manufacturers can not be the name of green signs to mislead the consumer.

Businessmen’s responsibility on biodegradable shopping bags

One Environmental Protection Agency provides 100 000 free reusable bags for large-scale shopping malls. The pink bags attract a lot of people. Meanwhile, the 2 RMB shopping bag in supermarket becomes not so popular.

Over the years, a small plastic bag a because of its easy to use and inexpensive, almost fills in a variety of shopping venues. But in recent years, with the environmental philosophy has been deeply rooted in people’s heart, they begin to re-examine the environmental problems caused by plastic bags. The plastic bags  is beginning to be rejected by many countries and regions In this context, for the sustainable development and environmental protection, China begin to limit the use of plastic shopping bags.

The pollution problems from plastic bags have been understood by the public. To protect the environment, we should get used to move away from plastic bags. That is the basic responsibility for citizens. Green and healthy lifestyle shopping social formation, only the administrative level of the ‘ban’ and the moral dimensions of advocacy, is not enough. Or, simply relies on the citizen's responsibility to refuse plastic bags is not realistic. The key is to use reusable shopping bags all the huge costs can not be isolated so that consumers bear, businesses which have to bear the corresponding environmental responsibility. If the bags are paid by customers, the implementation of ‘plastic limit’ will face much more realistic problems. Supermarkets sell reusable shopping bags no one is interested, free gift bags are fighting, they proved this point.

Which seems to be no clearly defined laws and regulations or the system, shopping malls must provide consumers with environmentally friendly shopping bags, price tag is not cheap bags for sale is the business of freedom, is not illegal. However, business ethics laws and regulations, after all, the bottom line is, in fact, businesses treat consumers, there are many things that are far above the law, which involves a business responsibility.

On the current situation, the environmental alternative to plastic bags, the price is relatively high, and then this piece of ‘costs’ can not be entirely by consumers alone, to whom the interests of the business but also alienation, to provide cheap or even free bags. China can learn from the practice of foreign countries, to develop a series of measures to support the system, on the one hand ban plastic bags from the source of production, and also to encourage and promote businesses and consumers together to say no to plastic bags, the two market objects work together for environmental protection.

There is commercial responsibility in a rpet bag. It seems that the businessmen pay the environmental cost and it influences the interests of businessmen. But for long term benefits, a business unit who has the courage to take public responsibility is bound to win more and wider range consumer trust and social reputation. It is conducive to the development of their own. Source:http://www.cnmhc.com

Policies and implementations of reusable bags

Since plastic bags have been put into use, they bring great convenience for human life and form a heavy environmental burden on the earth. ‘White pollution’ situation becomes worse, people begin to re-examine the environmental problems caused by plastic bags. More and more countries and regions are actively taking measures to limit the use of plastic bags. The global community began to say ‘no’ to plastic bags.

Europe: gets remarkable results on ‘white pollution’. With the continued popularity of environmental protection concept, the EU countries have taken various measures to deal with the ‘white pollution’, and achieve remarkable results. Stimulate free plastic bags cause more pollution. Many EU countries, large-scale retail stores, began to stop providing free plastic bags. This proved to be deal with the "white pollution" an effective way.

In the Netherlands, Belgium and Luxembourg, following the large supermarket chains Carrefour to stop providing free plastic bags in 2006, the Del Hydes and GB supermarkets from July 2007 onwards, in addition non-packaged foods and frozen fruits and vegetables, but no longer provide free plastic bags for other commodities. Ask customers for plastic bags, the supermarket plastic bags the size and quality according to different charge 0.05 euros (about $ 0.07) to 1.69 euros ($ 2.6) per fee.

Since 2004, Belgium began to push the limits of plastic shopping bags to call for supermarkets and other shopping sites no longer provide free plastic bags, while the customer's first purchase with the bad, the supermarkets, and free trade. By 2010, these measures are all the supermarkets in Belgium Walloon response.

In EU countries, a growing number of large supermarkets is not only no longer a one-off free plastic bags, disposable bags, but also ask the customer to charge VAT reusable bag. As the plastic bags of different size and quality, the fees charged are not the same, if the customer purchased a 0.3 euros (0.46 dollars) in disposable plastic bags, then one of the 0.1 euros ($ 0.15) fee for the cost of 0.2 euros ($ 0.3) for green taxes, these costs will be for plastic recycling and processing.

Irish Environment Minister pointed out that the plastic bag tax, allowing the public to change behavior, recognizing the importance of environmental protection. He believes that the tax effect is immediately visible, its positive impact on the environment is obvious, because the Irish environmental authorities found that ‘white trash’s indeed reduced. It is through this approach, in recent years, Ireland is not only effective control of the "white trash", but also increase the tax, made a double benefit effect.

The EU also attaches great importance to plastics recycling, because of increased packaging waste recycling rate of packaging materials can not only reduce energy consumption, save construction costs of waste incineration site, you can also reduce the production of packaging materials caused by environmental pollution, effectively reduce greenhouse gas emissions.

Africa: Governance plastic bags with varying results. Rwanda, South Africa and Kenya in recent years, the three African countries have taken to reduce "white pollution" of the measures, the measures taken by the three countries vary, and the results are very different. Three measures of Rwanda is the most stringent. It began in 2005 prohibiting the use and production of the thickness of 100 microns or less plastic bags, and also prohibits supermarkets and farmers markets to provide customers with plastic bags.

Implementation of the ban on plastic bags in Rwanda was very strict, and some supermarkets have been provided to the customer for breach of regulations was ordered closed plastic bags. Implementation of the ban before, Rwanda has had to organize a nationwide large-scale activity to pick up plastic garbage. Rwandan capital, Kigali airport asked passengers to discard plastic bags or store in the airport, at the same time buy bags. He himself had been the work of staff at the airport, taking away the plastic bag. Today, Rwanda is Africa's most neat and clean one of the countries, which pays close attention to environmental management of the government of Rwanda are not unrelated.

South Africa has suffered the pain of plastic bag pollution, scattered on the highway next to the fence and trees on the beach bags everywhere. South Africa in May 2003 introduced legislation to prohibit the production and import less than 80 microns thickness of plastic bags, violators can be fined up to 10 million rand (about $ 13,000) fine, and possibly jail.

Kenyan government announced a ban on production and imports of ultra-thin plastic bags with thickness of less than 30 microns last year and taxes 120% for other plastic bags.. Nakumate is Kenya's largest supermarket, it has 19 stores across the country. Kenya, the’ plastic limit’ after the enactment of Nakumate introduced a blue non-woven bags produced, on the cash register, each customer can get a free shopping bag .Source: http://www.cnmhc.com

What is the real reusable shopping bag

There are many kinds of shopping bags. Somebody thinks that the biodegradable shopping bags are the best, they will not produce pollutions after use and discarding. That is a wrong thought. Vice president of international food packaging association, Dong Jinshi says that, in order to ensure the resilience of plastic bags, currently on the market there are only 1 / 3 to 1 / 4 biodegradable plastic bags are with biodegradable ingredients, the others are difficult to degrade. Degradation of components according to the different degradation time of biodegradable plastic bags takes months to years. Although more than white trash ‘digest’ a short time a lot, but after a lot of waste in the environment is still very serious. Meanwhile, the current biodegradable plastics, there are still relatively low intensity (not strong), the problem of high cost. Therefore, the solution is not biodegradable plastic shopping bags polluting the most effective way. Relative to the recycling bag, now more international focus is to reduce the use of the premise of effective waste plastics recycling.
Plastic shopping bags are consumable products in daily people ‘s life , every year China consumes a lot of plastic shopping bags. Plastic shopping bags provide convenience for consumers, while, due to excessive use and recycling is not in place and other reasons, also caused a serious waste of energy resources and environmental pollution. In the ‘plastic limit’ implementation occasion of the year, many people mention this topic again - mixed, revived. Policies promulgated by the state policy require each person's understanding of consumer behavior and good co-ordination. Plastic shopping bags have been deep into the details of everyday life inside; Less and recycling use become everyone's responsibility.Reusable bags or reusable shopping bags are not just concern that whether the material is environmentally friendly, but also the consumer behavior. And it is the most critical one. No matter what kind of material shopping bags, if consumers do not use will result in waste and pollution.

Non woven bags are the ideal alternative. Firstly, the bag is strong and durable; the useful life is more than one year. But the plastic bags can not be damaged by sharp objects and heavy objects, it is usually difficult to re-use after using in a dozen times; Secondly, the bag is easy to recycle. The plastic’s main raw material is polyethylene due to molecular structure and stability, they are not easily broken,. If a large number of plastics bags are abandoned easily in the environment, they will cause the ‘white pollution’ and waste of resources. Thirdly, non woven bag can be made from old clothes, old bags, side bags, or a simple modification system into, that it really environmentally friendly and fashionable. Source: http:// www.cnmhc.com

Production process of reusable bag

The general production processes of reusable bags are: choose fabrics - cutting plant cut brace - printing - sewing - packaging.
When receiving an order of reusable bags, the first is to choose the fabric. The excellent fabric is good for the production of reusable bags .we should first choose the fabric with no crease, small differences in vertical and horizontal pull and hard hand feel. In selection of the fabric weight, the practical is appropriate.
Sometimes choose the fabric whose surface is gloss. Fabric surface gloss, so prepare for the post-printing, a good print, then print out the effect of one is very good. Thus, the overall effect will be very prominent, so go out shopping bags, will be well received by consumers. Sometimes choose to be hard on the fabric feel a bit. Hard little fabric, can be quite up, sustain them, highlighting the overall feeling of nonwoven bag, very practical, I am shopping, put a certain weight of objects, not broken is not bad. Safe and practical are standards of choosing the reusable shopping bags.
Similarly, the required vertical and horizontal tensile fabric small differences, but also to ensure that the load-bearing areas in shopping bags, has excellent performance. Fabric is good, into the warehouse, the next thing is how these Jumbo bags made of woven, cut a piece of it planted, a small section of fabric.
Reusable bag is a three-dimensional rectangular or cube. Well, it has six faces, which, at the top is empty, so there are only five shopping bags face, and then a large area before and after, left and right sides, with a bottom surface. Referred to here is the production of nonwoven bag sewn method and ultrasonic bag which is quite different. According to size, with automatic slicing machine, cutting machine, the fabric cut into small pieces the size of fabric required. Including a large cut is used to print the front and rear with three sides with the bottom of the fit. Then the side, carry hand side of the bag. This is called cutting, refers to the hand and carry bag this side, because they are very narrow, it must be cut into small strips to match the finished product.
The printing: screen printing is generally used, because it is a piece of hand-printed, so progress will be faster than the machines that print to a slower, of course, will cost more than the machine to print to a high point, but its advantages, is also very obvious, very small amount can be printed, the error rate is relatively low. Printing, pay attention to the printed text, graphics have good fullness, and size to be able to grasp the whole shopping bag highlight the effect.
Sewing: according to certain specifications, and style, like sewing clothes, the large fabric, small pieces, carry hand, edging and other fabric sewn together to see the finished product on a shopping bag. This includes a lot of sewing methods, such as hand and carry a large interface, you need not need to cross, a cross is to increase firmness. Edge is to take a few lines, with the length of the packet and so on.
Packing. Cartons in accordance with certain specifications, a box of 100 pieces, or 200 pieces a box, print fonts on the boxes, so that boxes of reusable bags through the logistics departments are sold to the general consumers. Now reusable bags are with a large number of styles. The work and processes of each kind are slightly different. Source:http://www.cnmhc.com
