safety

When the glass is damaged by external force, the fragments will be broken into small particles like honeycomb-shaped obtuse angles, which will not cause serious harm to the human body.

high strength

Same thicknessTempered glassThe impact strength is 3 to 5 times that of ordinary glass, and the bending strength is 3 to 5 times that of ordinary glass.

Thermal stability

Tempered glass has good thermal stability, can withstand a temperature difference of 3 times that of ordinary glass, and can withstand changes in temperature difference of 3 00 ℃.

advantage

Compared with ordinary glass, the strength is increased several times, and it is resistant to bending. And it is safe to use, and its increased load-bearing capacity improves the fragile nature. Even if the tempered glass is damaged, it will show small fragments without acute angles, which greatly reduces the harm to the human body. Compared with ordinary glass, tempered glass has a rapid cooling and heat resistance of 3 ~ 5 times, and can generally withstand a temperature difference of 2 5 above 0 degrees, which is obvious for preventing thermal cracking Effect. It is a kind of safety glass. To ensure the safety of qualified materials for high-rise buildings.

Disadvantages

Disadvantages of tempered glass:

1 . The tempered glass can no longer be cut and processed. The glass can only be processed to the required shape before tempering and then tempered.

2 . Although the strength of tempered glass is stronger than ordinary glass, but tempered glass has the possibility of self-detonation (self-rupture), while ordinary glass does not have the possibility of self-detonation.

3 . The surface of tempered glass will have unevenness (wind spots), with a slight thickness thinning. The reason for the thinning is that after the glass is softened by hot melting, it is rapidly cooled by strong wind force, so that the crystal gap inside the glass becomes smaller and the pressure becomes larger, so the glass is thinner after tempering than before tempering. In general, {{1}} ~ {{2}} mm glass becomes thinner after tempering 0. 2 ~ 0. 8 mm, {{6} } ~ 2 0mm glass is thinned after tempering 0. {{1 0}} ~ 1. 8 mm. The specific degree depends on the equipment, which is why the tempered glass cannot be mirrored.

4. The flat glass used for construction after passing through the tempering furnace (physical tempering) will generally have deformation, and the degree of deformation is determined by the equipment and technical personnel. To a certain extent, it affects the decorative effect (except for special needs).
