toughened glass

Toughened glass is the plate glass heated to the softening point, formed on the surface of the compression and in the glass surface rapid cooling, the compression should I re r distribution on the surface of the glass, and leads to tensile stress in the center layer. Due to strong equal compression stress, the pressure generated lead tensile stress, is glass of strong compression should be offset by force, increases safety degree of the use of glass.

Toughened glass is ordinary annealed glass first cut into required size, and then heated to near the softening point of 700 degrees, and rapid and uniform cooling of (usually glass 5-6mm under 700 degrees high temperature heating 240 seconds, cooling about 150 seconds. 8-10mm glass at high temperature for 500 seconds, 700 seconds to heat, cool down about 300 seconds. In short, depending on the thickness of the glass, the choice of heating cooling time is also different. Tempered glass surface to form a uniform compressive stress, so that the bending and impact strength of the glass can be improved, and its strength is about four times more than that of ordinary annealed glass. Have been tempered good tempered glass, can no longer be any cutting, grinding or damaged, otherwise will be due to damage even compressive stress on the balance and "destroyed".

Excellent performance

The flexural strength of the toughened glass than ordinary glass increased three times, anti impact strength than ordinary glass increased to 4-6 times, thermal stability than ordinary glass increased more than three times. Therefore, it when subjected to external force, is not easy to be damaged, even though they were damaged and splinters were peanut like small particles, no edge, harmless, safe. When the toughened glass is used in the curtain wall, the wind pressure coefficient is much larger than that of the ordinary glass.

Application range

Usually tempered glass is widely used in high-rise building doors and windows, glass curtain wall, indoor partition glass, lighting ceiling, sightseeing elevator channel, furniture, glass railings.

Can be applied in the following industries:

1  building, building templates, decoration industry (example: doors and windows, curtain wall, interior decoration, etc.)

2  1.5-3mm tempered glass used in photovoltaic solar industry

3  furniture manufacturing industry (glass tea table, furniture, etc.)

4  home appliance manufacturing industry (TV, oven, air conditioning, refrigerator and other products)

5  electronics, instrumentation industry (mobile phones, MP3, MP4, watches and clocks, and other digital products)

6  automotive manufacturing industry (automotive windshield, etc.)

7  household products industry (glass chopping board)

8  specialty industries (military glass)
