　Tempered glass
Toughened glass is common glass through the toughened glass furnace heated to softening point nearby, and then the uniform cooling rapidly after get the surface of the glass with a strong uniform pressure stress, make its mechanical strength increase, effectively improve the resistance of the glass wind pressure and impact resistance performance, and improve the thermal shock resistance of the glass.
The character of toughened glass:
1, safety: glass break subsequent similar alveolate SuiXiao obtuse Angle grain, won't harm the body.
2, high strength: tempered glass strength is common glass 4 ~ 5 times.
3, deflection: better than common glass big 3 ~ 4 times.
4, thermal stability, toughened glass has good heat stability, can bear temperature is common glass 3 times, can bear 300 ℃ of temperature changing.
5, extensive application: it is widely used for mechanical strength and security requirement of high places
