Tempered glass (Reinforced glass) Glass with compressive stress on the surface. Also called strengthened glass. The use of tempering method to strengthen the glass began in France in 1874.
Generally, outdoor street lamp glass is made of tempered glass.
Tempered glass is actually a kind of prestressed glass. In order to improve the strength of glass, chemical hardening treatment or physical hardening treatment is usually used to form compressive stress on the surface of the glass. When the glass is subjected to external force, the surface stress is first offset, thereby increasing the bearing capacity. Ability to enhance the glass's own resistance to wind pressure, cold and heat, and impact.
Features:
1. The strength is several times higher than that of ordinary glass, and the bending resistance is good.
2. It is safe to use, and its load-bearing capacity is increased to improve the fragile nature. Even if the toughened glass is damaged, it will appear as small fragments without acute angles, which greatly reduces the damage to the human body. The toughened glass is more resistant to rapid cold and heat than ordinary glass. An increase of more than 3 to 5 times, generally can withstand a temperature difference of more than 250 degrees, has a significant effect on preventing thermal cracking. It is a kind of safety glass.
Safety: When the glass is damaged by external force, the fragments will become small obtuse-angle particles similar to honeycombs, which are not easy to cause harm to the human body.
High strength: The impact strength of tempered glass of the same thickness 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 more than 3 times that of ordinary glass, and can withstand temperature changes of 200°C.
Uses: Widely used in: safety glass for furniture, electronic appliances, decoration.
