Tempered glass is a kind of prestressed glass, in order to improve the strength of the glass, the commonly used method of chemistry or physics, formed on the glass surface compressive stress, the glass can first offset surface stress of external force, so as to improve the bearing capacity of reinforced glass itself, wind, cold and heat, shock resistance etc..
Toughened glass features
Tempered glass is a glass heating quality of the softening point, in the glass surface rapid cooling, the compression stress distribution on the surface of the glass, and Zhang cited the stress in the center layer. Because the compression has strong equal stress, so that the pressure generated by Zhang Yin stress is glass strong compression force offset, thereby increasing the safety glass.
1: after tempering strength increased mechanical strength, impact resistance of glass, bending strength can reach 4 - 5 times of ordinary glass.
To improve the thermal stability of 2: tempered glass can withstand huge temperature difference and not damaged, resist and variable temperature capacity is 3 times the ordinary float glass of the same thickness.
3 improved safety: tempered glass by strength after damage, rapid appearance of small angle grain, so as to maximize the personal safety.
