Tempered glass is actually a kind of pre-stressed glass. In order to increase the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface. When the glass withstands external forces, it first cancels the surface stress, thereby improving the bearing capacity and improving the glass resistance. Tensile strength.
There are two main advantages of tempered glass. The first is that the strength is several times higher than that of ordinary glass, the bending strength is 3 to 5 times that of ordinary glass, and the impact strength is 5 to 10 times that of ordinary glass. Out of security. Use safety is the second major advantage of tempered glass. Its increased bearing capacity improves fragile properties. Even if the tempered glass is destroyed, small fragments with no acute angles appear, which greatly reduces the harm to human bodies. The tempered glass has a resistance to rapid cooling and heating that is 2 to 3 times higher than ordinary glass. Generally, it can withstand changes in temperature difference above 150LC, which has a significant effect on preventing thermal explosion.
Tempered glass is processed by ordinary flat glass or float glass. Ordinary flat glass requires special or first-class products; float glass requires superior or first-class products.
There are two kinds of processes for producing tempered glass: one is to process ordinary flat glass or float glass under specific process conditions through quenching or air cooling quenching. The other is that ordinary flat glass or float glass is processed by ion exchange method to change the composition of the glass surface to form a laminated stress layer on the glass surface.
Tempered glass has the characteristics of high impact strength (4 to 5 times higher than ordinary flat glass), high bending strength (5 times higher than ordinary flat glass), good thermal stability, and smooth, transparent, and cuttable characteristics. When it is damaged by super strong impact, the fragments are scattered fine particles without sharp edges, so it is also called safety glass.
Tempered glass is divided into flat tempered glass and curved tempered glass according to shape. There are eight types of flat tempered glass thicknesses of 4, 5, 6, 8, 10, 12, 15, 19mm, and three types of curved tempered glass thicknesses of 5, 6, and 8mm.
Tempered glass is divided into two categories: superior product and qualified product according to its appearance quality.
Tempered glass is divided into: I, II and III.
