The situation and development trend of China building coated glass

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. Building energy consumption as a large, real impact on people's lives and health, how to improve building energy efficiency and green building standards for building energy saving has become the focus.

Low-E coated glass and thin-film photovoltaic glass and will become the mainstream of the market trends for energy-saving, environmental protection and green energy, green building construction solar integration play a decisive role. Market demand, potential for development is good, adapts to energy conservation policies, is a manufacturer of architectural coatings-related focus, in order to better safeguard the healthy development of architectural coatings market, the manufacturers need to focus on the following aspects.

First, the manufactures should focus on development capacity for sustainable technology and have a certain ability to develop new products and titanium dioxidetechnologies. The second is to increase investment in product testing equipment and improve product testing methods and product quality. Third, combining with the market situation and eliminating the backward technology. Meanwhile, they shpuld timely adjust the company's product structure. Fourth, basing on their own terms, the manufactures need to break up the conventional wisdom. The bigger equipment doesn’t mean that the quality is better. The imported equipment is not mean to be better than domestic equipment. But according to the object of the enterprise market and market share, as long as the enterprise adapt to the corresponding market areas and levels, the companies will continue to grow and develop. Fifth, focus on enterprise hardware and software, 30% of efforts is for equipment, 50%for technology and 20% for management. Among them, technology is the key point in future survival.
