The Benefits Of Homogeneous Tempered Glass

- Apr 26, 2018 -

Tempered glass is actually a kind of prestressed glass. In order to increase the strength of the glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass receives external force, the stress of the surface layer is firstly offset, thereby increasing the carrying capacity and strengthening the glass self-resistance. Wind pressure, cold and heat, impact and so on.

product advantages:

1, high strength, 3 to 5 times that of ordinary glass.

2, high safety performance, broken into a honeycomb-like small pieces of obtuse angle.

3, good thermal stability, can withstand more than 250 °C temperature changes, is 3 times that of ordinary glass.

The reason for the explosion of tempered glass is that sulfur and nickel impurities are mixed in the glass manufacturing process, and nickel sulfide is generated at a high temperature. Nickel sulfide has two kinds of crystals, which is α phase at high temperature (t>380°C) and β phase at low temperature. Due to the rapid cooling during tempering, the alpha phase does not have the ability to convert to the beta phase. During use, the metastable α-phase at room temperature slowly transforms into a stable β-phase, with a volume expansion of about 4% causing the tempered glass to blew. The benefits of tempered glass after homogenization

The role of the homogenizing furnace is to completely transform the nickel sulfide α phase into a low temperature stable β phase, and the baked glass can no longer be detonated (detonated), which can effectively ensure that the tempered glass does not bleed.
