What is the tempered glass? What is the difference with ordinary glass?
Tempered glass is actually a kind of prestressed glass, in order to improve the strength of the glass, usually using chemical or physical methods (physical means that the wind quenching, the current building glass are used in this method) in the glass surface to form compressive stress, glass bear external force When the first to offset the surface stress, thereby enhancing the carrying capacity, improve the glass tensile strength. The main advantages of tempered glass are two, the first is the strength of several times higher than the ordinary glass, bending strength is 3 to 5 times the ordinary glass, the impact strength is 5 to 10 times the normal glass to improve the strength at the same time also increased The security. The use of safety is the second major advantage of tempered glass, its increased carrying capacity to improve the fragile nature, even if the destruction of tempered glass was no small angle of the small pieces of damage to the human body greatly reduced. Tempered quenching and cooling properties of tempered glass than ordinary glass has 2 to 3 times the increase, generally can withstand more than 150 ℃ temperature difference, to prevent the thermal cracking has a significant effect.
From the appearance of the general do not see how much different with ordinary glass, but through the polarized sunglasses can be seen on the tempered glass with rainbow plaque - some of the old micro-van front can also be seen, this is tempered glass The unique phenomenon.
