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 China telescope eyepieces 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.
