Toughened Tempered Safety Glass

Tempered glass is the so-called safety glass, toughened tempered safety glass is through the principle of material tempering, when the glass heats up to close to the softening state in the instant cooling, so that the glass inside the tempered stress layer, thereby increasing the glass surface of the pressure resistance and impact resistance, so it will be more strong, not easy to break. And even after broken particles are not very sharp, will not cause harm to the human body.

Tempered glass or also known as safety glass, are all strengthened glass, glass itself has a high compressive strength, when the glass is subjected to external force, the pressure layer can offset part of the tensile stress, to avoid the fragmentation of the glass, although the toughened tempered safety glass is in a larger tensile stress state, but the inside of the glass without defects, will not be built into damage, So as to achieve the purpose of improving the strength of glass.

The mechanical strength of tempered glass is 4 to 5 times that of ordinary glass. The thickness of 5mm tempered glass, bending strength can generally reach the impact strength of domestic is about 1.53 to 3 times that of ordinary glass; The mechanical strength of tempered glass is 4 to 5 times that of ordinary glass. The thickness of 5mm tempered glass, the bending strength can generally reach the impact strength of domestic is about 1.53 to 3 times that of ordinary glass.

1. Tempered glass is safe. When it is damaged by the outside world, it will not be like ordinary glass, but will appear as honeycomb-like obtuse-angled small particles, which will not easily cause harm to the human body;

2. Tempered glass has high strength. Compared with ordinary glass of the same thickness, the impact resistance of tempered glass is 3-5 times stronger, and the bending resistance is 3-5 times stronger;

3. Tempered glass is unstable. The temperature difference that tempered glass can withstand is 3 times that of ordinary glass, and the temperature difference it can withstand is about 300°C.

One is to process ordinary flat glass or float glass through quenching or air-cooling quenching under specific process conditions. The other is to process ordinary flat glass or float glass through ion exchange to change the composition of the glass surface to form a compressive stress layer on the glass surface.
