(www.landglass.com) located in Luoyang City, Henan Luoyang City Road on the 12th king, Contact: Mr. Qin five, coated and tempered coated glass Low-E glass, especially Low-E glass The steel production, is the largest problem, difficult to master the technical parameters of a glass in the presence of steel production. When the coated glass and Low-E glass tempering glass up and down the biggest difficulty is not the same on both sides of the heat absorption rate. Glass surface has a high emissivity (approximately 0.9), the surface temperature rises too fast, but low emissivity coated surface (as low as 0.1 to 0.23), the heating process a large amount of the reflected radiation, by thermal radiation is not easy transmitted to the inner surface of the glass. This asymmetric heat absorption rate, resulting in an asymmetric upper and lower surfaces of the glass sheet temperature, causes bending glass, from a variety of defects fog, falling film, optical distortion, arcuate and the like. 2.3 Measures for controlling thermal deformation due to uneven cooling caused by the stress generated in the cooling process is uneven, the cooling rate can be adjusted by adjusting the glass surface air pressure gate. If the glass is bent downward, which can be adjusted by increasing the pressure at the bottom of the grille to improve cooling rate of the surface under glass; if the glass bending upward, through the upper portion of the gate to increase the wind pressure on the glass surface to increase the cooling rate regulation.
