Introduction of vacuum glass

Vacuum glassWindows and doors is a vacuum glass + profile into the doors and Windows. So-called vacuum glass is will two tablets glass, a for white glass, another a for low radiation degrees film glass (LOW-E glass) of four week with glass powder melt seal, Zhijian with small of support real separated, its thickness for 0.1~0.2mm, each 25mm deployment a formed matrix, balance atmosphere pressure, in high temperature Xia exhaust pumped into vacuum, then will exhaust mouth with glass melting seal died. Vacuum pressure in 0.1PA (an atmospheric pressure of 100000pa).
　　
　　Glass vacuum heat insulation, sound insulation, condensation prevention works
　　
　　As we all know, heat transfer there are three ways a, b convection c direct conduction, thermal radiation. Vacuum glass vacuum chamber with no air, there is no direct transmission medium to form convection, conduction conditions a, b damage, improve the thermal resistance of vacuum glass. Production in the two pieces of glass and vacuum glass, glass is a LOW-E film, its metal film placed in the vacuum chamber, neither oxidation guarantees use life and its reflection infrared efficiency into full play, effectively reduce transmission of radiant heat. Above, the principle of vacuum glass thermal insulation is used in pot. So the insulation performance than insulated glass 4 times, 6 times higher than single layer of glass. A standard vacuum insulation glass 370mm thick concrete walls.
　　
　　Due to the characteristics of vacuum glass structure, the existence of vacuum, no sound transmission medium, blocking transmission of sound, sound insulation performance than insulated glass about 10dB. Excellent sound insulation properties. Vacuum vacuum layer of glass without air and no water vapor molecules, sealed, thermal resistance, and in the winter will not produce condensation.
