Tempered glass and ordinary glass technology and raw materials What is the difference in detail Thank you
General material the same. Tempered glass is the ordinary flat glass or float glass in a specific process conditions, quenching or air-cooled quenching method from the processing, has "tempered glass" entry.
The production process of the glass is: raw material crushing, sieving, weighing, mixing, high temperature (1600 degrees) melting into glass liquid, glass liquid homogenization cooling forming, cutting, annealing, cooling, inspection, packaging.
The main raw materials are: quartz sand or sandstone, feldspar, soda ash, limestone, dolomite, in addition to soda ash are ore raw materials, need to break into the appropriate size.
Tempered glass is a reusable product of ordinary glass.
The main components of its glass is silica, calcium oxide and sodium oxide, so called sodium silicate glass. There are two ways to temper glass, physical steel (air-cooled steel) and chemical steel.
Tempered glass is used in the chemical steel method. The principle is to use the "head" of the larger potassium ions to replace the glass surface "head" smaller sodium ions, making the glass surface was tensioned, that is, the formation of compressive stress, so that the glass has a very high impact resistance Increased by 5 times).
Physical tempered architectural glass also makes the glass surface compressive.
