How to improve the carrying capacity of tempered glass

Tempered glass is actually a kind of prestressed glass. In order to improve the strength of the glass, chemical or physical methods are generally used to form compressive stress on the surface of the glass. When the glass receives external force, the surface stress is mainly offset, and then the bearing capacity is improved to enhance the glass's own resistance. Wind pressure, cold and heat, shock, etc.

One is that the strength is improved several times compared to ordinary glass, and it is resistant to bending. The flexural strength is 3 ~ 5 times that of ordinary glass, and the impact strength is 5 ~ 10 times that of ordinary glass. Together with increasing strength, it also improves safety.

The second is the use of safety, its bearing capacity can be increased to improve the fragile properties, even if the tempered glass is damaged, there are no small fragments with acute angles, and the damage to the human body is greatly reduced. The quenching and thermal resistance properties of tempered glass are better than ordinary glass There are 2 ~ 3 times of progress, and generally acceptable changes in temperature difference above 150 LC, which has a significant effect on avoiding thermal cracking.

Tempered glass is the heating of high-quality float glass close to the softening point, rapid cooling on the surface of the glass, so that the compressive stress is spread on the surface of the glass, and the tensile stress is on the central layer. The resulting tensile stress is offset by the strong compressive stress of the glass, and then the safety of the glass is added.

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

High strength: The impact strength of tempered glass with the same 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 good thermal stability, the acceptable temperature difference is 3 times that of general glass, and the temperature difference of 200 ℃ can be accepted.
