[China Glass Network] Energy conservation is a new theme in today's society. Building energy consumption accounts for a relatively high proportion of total social energy consumption. It is known that China's new construction area is nearly 4.5 billion square meters per year, of which more than 99% are high-energy buildings. The environmental protection and energy conservation of buildings is extremely urgent. Doors and windows, especially glass, are the weaker parts of building energy loss, accounting for about 30% of the building area, while energy consumption accounts for 2/3 of the total energy consumption, which is the main reason for building heating and cooling energy consumption. In the past five years, researchers have conducted extensive exploration and research, and the use of energy-saving glass has also increased. Recently, low-emission coated glass, solar-controlled coated glass, glass film, heat-absorbing glass, insulating glass, vacuum glass and other energy-saving glass have been developed. The average annual growth rate of products and usage is more than 40%, but these products are often limited by the reasons of low visible light transparency, complicated process conditions and high price. Beijing Zhisheng Weihua's transparent thermal insulation coating is a relatively recent development of a glass energy-saving thermal insulation coating that can block the infrared light and ultraviolet light of the sun, while maintaining high visible light transmittance, because it is environmentally friendly and separated. The reason of good heat effect, simple preparation process and low cost provides a new direction for the problem of glass insulation, and has a good application prospect in the field of architectural glass.
Zhisheng nano glass insulation coating only needs to apply a few micron thickness, so that the indoor and outdoor temperature difference can reach 6 degrees Celsius, the infrared shielding rate reaches 70%, the visible light transmittance reaches 80%, and the ultraviolet blocking reaches 99%. The air conditioner can also achieve the effect of “warm winter and cool summerâ€. This coating is ZS-311 transparent thermal insulation coating produced by Beijing Zhisheng Weihua Company.
Comparative test of thermal insulation effect of transparent thermal insulation coating:
150mm × 100mm × 5mm glass two pieces, one glass coated ZS-311 transparent heat insulation coating, the other one is not painted, brushed one side, two hollow boxes, thermometer, exposed to the sun, different time Test the temperature inside the box and the results show:
The contrast test between the coated glass and the blank glass. At the beginning of the test, the temperature in both chambers increased. After 1 hour, the temperature gradually increased. During the whole process, the temperature of the compartment in which the paint was applied was always lower than that. The temperature on the side of the brush. After 0.5 h of irradiation, the difference between the two room temperatures reached 5 ° C, and the temperature difference increased with time. After 12 h, the air temperature difference was 7 ° C. It can be seen that ZS-311 Zhisheng transparent heat insulation coating has obvious summer glass insulation and cooling effect.
