Toughened glass and ordinary glass, process and raw materials what is the difference, a little more detailed, thank you
Toughened glass is the re processed product of ordinary glass.The main components in the glass is silicon dioxide, calcium oxide and sodium oxide, so called silicate glass. There are two ways to make glass toughened. They are physical tempered (air cooled steel) and chemical steel.Tempered glass adopts a chemical tempering method. The principle is the sodium ion with the "head" the larger potassium ions replace the glass surface "head" is small, so that the glass surface is a state, which is the formation of compressive stress, so that the glass has very high impact resistance (increased by about 5 times).
Glass production process is: raw material crushing, screening, weighing, mixing, high temperature (1600 degrees) melting into glass, glass homogenization, cooling molding, cutting, annealing, cooling, inspection, packaging.The main raw materials are: quartz sand or sandstone, feldspar, soda ash, limestone, dolomite, etc., in addition to soda ash are ore raw materials, need to be broken into the appropriate size.
Same material. Tempered glass is ordinary flat glass or float glass in a specific process conditions, by quenching or air-cooled quenching processing processing, Baidu has "toughened glass" entry.
