Tempered glassIn fact, it is a kind of prestressed glass. In order to improve the strength of the glass, chemical or physical methods are generally used to form a compressive stress on the surface of the glass. When the glass receives external force, it first offsets the surface stress, and then improves the bearing capacity and enhances the glass's resistance to wind pressure Sexuality, coldness and heatness, impact, etc.

The first is that the strength is several times higher than ordinary glass, and it is resistant to bending. The bending strength is 3 ~ 5 times that of ordinary glass, and the impact strength is 5 ~ 10 times that of ordinary glass. Increasing the strength also improves safety.

The second is the safety of use. The load-bearing capacity can be increased to improve the fragile properties. Even if the tempered glass is damaged, it has small fragments without acute angles, which greatly reduces the damage to the human body. There is an increase of 2 ~ 3 times, and it is generally acceptable to change the temperature difference above 150 LC, which has a significant effect on avoiding thermal cracking.

Tempered glass is the heating of high-quality float glass near the softening point, rapid cooling on the surface of the glass, so that the compressive stress is distributed on the surface of the glass, and the tensile stress is on the central layer. The induced tensile stress is offset by the strong compressive stress of the glass, and then the safety of the glass is increased.

Safety: When the glass is destroyed by external force, the fragments are broken into small obtuse particles similar to honeycomb, which is not easy to damage the human body.

High strength: The impact strength of tempered glass with equal thickness is 3 ～ 5 times that of ordinary glass, and the bending strength is 3 ～ 5 times that of ordinary glass.

Thermal stability: Tempered glass has excellent thermal stability, the acceptable temperature difference is 3 times that of general glass, and the temperature difference of 200 ℃ can be accepted.
