Characteristics of tempered glass

Characteristic security
When glass is damaged by external forces, the fragments will form blunt edged small particles resembling honeycomb shapes, which are not likely to cause serious harm to the human body.

High-intensity
Tempered glass of the same thickness has an impact strength that is 3 to 5 times that of ordinary glass, and a bending strength that is 3 to 5 times that of ordinary glass.

Thermal stability
Tempered glass has good thermal stability and can withstand a temperature difference three times that of ordinary glass, with a temperature variation of 300 ℃.

Advantage
1. It has a strength several times higher than ordinary glass and is resistant to bending.
2. It is safe to use, and its increased load-bearing capacity improves its fragility. Even if tempered glass is damaged, it will form small fragments without sharp angles, greatly reducing the harm to the human body.; The rapid cooling and heating resistance of tempered glass is 3-5 times higher than that of ordinary glass, and it can generally withstand temperature differences of over 250 degrees, which has a significant effect on preventing thermal cracking. It is a type of safety glass. To ensure the safety of qualified materials for high-rise buildings.

Shortcoming
Disadvantages of tempered glass:
1. Tempered glass cannot be further cut or processed. It can only be processed to the desired shape before tempering.
2. Although tempered glass has stronger strength than ordinary glass, it has the possibility of self explosion (self rupture), while ordinary glass does not have the possibility of self explosion.
3. The surface of tempered glass may have unevenness (wind spots) and a slight thinning in thickness. The reason for thinning is that after the glass is melted and softened, it is rapidly cooled by strong wind, which reduces the crystal gaps inside the glass and increases the pressure. Therefore, the glass is thinner after tempering than before tempering. Generally, 4-6MM glass becomes thinner by 0 after tempering. 2-0. 8MM, 8-20MM glass becomes thinner by 0 after tempering. 9-1. 8MM. The specific degree depends on the equipment, which is also the reason why tempered glass cannot be used as a mirror.
4. The flat glass used in buildings that has been tempered through a tempering furnace (physical tempering) generally undergoes deformation, and the degree of deformation is determined by the equipment and technical personnel's process. To some extent, it affects the decorative effect (except for special needs).
