Kindwei Tempered glass film is actually a kind of pre-stressed glass. In order to increase the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass withstands external forces, it first cancels the surface layer stress, thereby improving the carrying capacity and improving the glass. tensile strength.

There are two main advantages of tempered glass film. The first is that the strength is several times higher than that of ordinary glass, the bending strength is 3 to 5 times that of ordinary glass, and the impact strength is 5 to 10 times that of ordinary glass. Improved security. Use safety is the second major advantage of physical toughened glass. Its increased load capacity improves fragile properties. Even if the toughened glass is destroyed, small fragments without acute angles are displayed, which greatly reduces the harm to human bodies. The tempered glass has a resistance to quenching and heating that is 2 to 3 times higher than that of ordinary glass. Generally, it can withstand temperature changes of more than 150 degrees, which has a significant effect on preventing cracking.
