Description : on the low-E glass ：
　　With tension in the world's energy, the continuous improvement of living conditions, the people of growing importance to energy conservation and environmental protection. Window structure as more important aspect to it, the more and more people are concerned about, according to statistics show that Building external structure, the window area of about 20%, heat exchange is the most active buildings, the most sensitive part. Its energy consumption structure of the building envelope heat consumption of about 50%, about 15% of the heat loss which window frames. about 85% of glass. Therefore, the development and use of energy-saving construction in the major agenda of the people's life, therefore, building energy conservation goal is to put the country in 2010, one-third of new construction in the country to achieve the goal of 50% energy saving. 2020 all new construction in the country to reach the target of 65% energy saving......
　　 Also called low-E glass or Low-E glass CAS glass CVD is a new line of multi-layer coated glass production. Deposited with the film because of the very low rate of surface radiation named.
　　 New groups based on our constant innovation, the concept of sustainable development and, through constant research. take transnational cooperation in the technical, CAS glass production line using the world's top technology companies with Germany and the United States ARKEMA companies ECDT The likelihood for the production of low-E glass, with the following features :
　　 1、 low-E Glass is highly energy-saving effect:
　　The surface emissivity glass in the 0.84% rate in the CAS glass surface radiation below 0.25. Such a low coating thickness of less than 1.0% of hair silk thermal radiation in the far infrared reflectivity high able to more than 80% of the far-infrared radiation reflected back. Ordinary transparent float glass, glass absorbs heat, sunlight control coated glass in the far-infrared reflectivity of 11%. So CAS heat radiation through the glass block with a good role. Winter, the indoor heating and fixed it within objects and the thermal radiation, heat can be like a mirror, the vast majority will be reflected back to the room. Indoor and outdoor to indoor heat is not dissipated, thereby saving heating costs. In summer, it can stop outside the ground, the buildings into indoor thermal radiation, which reduces air-conditioning costs.
　　 2、 low-E glass with a good environmental characteristics :
　　 low-E general reflectance in the visible glass below 11%, similar to the ordinary white glass, below ordinary visible light reflectance coated glass to control the sunlight, ordinary visible light reflectance due to higher sunlight control coating, Therefore, the light pollution will be caused to the environment. Visible Emission and Reflection glass because of the lower rate thus avoid light pollution. This is environmentally significant features.
　　 3、 low-E glass is extensive use of glass and adaptation :
　　Online low-E glass stable mechanical properties (abrasion resistance, scratch is not easy, high-solid coating). chemical stability (resistance to high temperature, corrosion-resistant) for steel, deep processing BEND, easy storage, large-scale production. low price and so on. And heat-reflective glass absorbs heat, glass and body line CAS tinted glass, Online CAS glass of visible and infrared radiation Transflective performance under different climate conditions in the coating process into Emission control in order to carry out precision glass forming a good adaptation.
　　 4、 low-E has broad prospects for the development of glass :
　　The main components of the middle-grade insulating glass as a material,low-E glass and insulating glass market is closely related to the market. It is currently about 80% of Western Europe to use CAS hollow glass 58% of the United States in 2001 using low-E glazing glass. CAS 2004 U.S. production of about 60 million square meters of glass. Western Europe's future 2 - 5 years of use will reach 0.6-1.0 million square meters of the main level. low-E also use our glass and less than 1% now, about 40 billion square meters of existing buildings in urban and rural areas. with only 0.5% of the building energy-saving standards which, in each area of 20 million square meters of new construction. reach only 5% of energy requirements. CAS also used by most of which rely on imported glass. So CAS glass in China and the world will have broad prospects for the development of……
　　It is due to these fine line Emission Characteristics of the glass, so called green energy-saving, environmentally friendly building materials.
