Features of tempered glass:    Tempered glass and semi-tempered glass are the glass surface obtained by heating and quenching the normal glass with strong and uniform compressive stress.    Glass with multiples in strength.    Surgery of tempered glass The compressive stress is above 90MPa, and the surface compressive stress of semi-tempered glass is between 24-69MPa.       1.  Safety: After the glass is broken, it becomes a honeycomb -like crushed small blunt corner particles, which will not cause major harm to the human body.     2.  High -strength: The strength of the tempered glass is 4 to 5 times that of ordinary glass.     3.  Deepness: 3 to 4 times larger than ordinary glass.      4.  Heat stability: The tempered glass has good thermal stability. The temperature that can withstand it is 3 times that of ordinary glass. It can withstand the temperature difference of 300 ° C.     Tempered glass is a safety glass and is widely used in places with high requirements for mechanical strength and safety.Such as: glass doors, architectural curtain walls, Facade       windows, indoor partitions, Furniture, close to heat sources and Partitions in severely affected areas by hot and cold …
