Features of Tempered Glass
Tempered glass belongs to safety glass ; and it is a kind of prestressed glass . To increase the strength of the glass , a physical method is used to form a compressive stress on the glass , a physical method is used to form a compressive stress on the glass surface .When the glass receives an external force , it will first counteract the surface layer stress , thereby improving the load carrying capacity , and enhancing the capacity to againsr wind pressure , cold , heat , impact and so on .
Safety
When the glass is damaged by an external force , the broken pieces will form like a honeycomb obtuse-angled small particle , which will not cause considerable damage to the human body.
High Rigidity
Under the same thickness , the impact strength of tempered glass 3 to 5 times more than the ordinary glass , and the bending strength is also 3 to 5 times than the srdinary glass.
Thermal Stability
Tempered glass has good thermal stability , which can bear 3 times the temperature difference of ordinary glass with 250

Advantages
Firstly, the strength is several times higher than ordinary glass,and it is resistant to bending. The second is safety. Its carrying capacity improves the fragile nature, the broken pieces are small but without acute angles , which will greatly reduce the damage to the human body. Tempered glass's heat-resisting property is 3 to 5 times higher than ordinary glass. Generally , it can bear a temperature differece of 250 degrees or more . It has a sigrdficant effect on preventing hot burst. It is a type of safety glass that protects high-rise buildings. The building provides qualified materials for safety.
Disadvantages
Disadvantages of Tempered Glass
The tempered glass cannot be cut and processed again. The glass can only be shaped as requested before tempering and then tempered.
Tempered glass is stronger than the ordinary glass but there is the possibility that it will explode by itself, which the ordinary glass won't happen.
The surface of the tempered glass will be inflated (wind spot) , which will cause the slight change for the thickness. The reason why the glass is getting thinner is because after the glass got soften in the furnace and got cool down by the strong wind , the crystal gap inside the glass will become smaller, and the pressure will be higher, then the glass will get thinner after the tempering. Normally, one 4~6mm glass will reduce 0.2~0.8mm after the tempering , 8~20mm glass will reduce 0.9~ 1.8mm . The actual situation is depending on the specific cases, that's also why the tempered glass cannot make mirror.
Features of Heat Strengthened Glass
Heat Strengthened glass is between ordinary flat glass and tempered glass. It has some of the advantages of tempered glass, such as higher stre ngth than ord in ary glass, and avoiding the poor flatness, easy to get self-explode, and broke by whole of tempered glass in the same time. When the heat Strengthened glass breaks, it will crack radially along the source. Generally , there will be no tangential crack propagation, so the entire structure will not collapse after the damage.
