Chemical tempering low temperature ion exchange is simple alkali salt solution of glass in 400 ℃, chemical tempering and tempering principle is different, mainlyused to enhance physical toughened thick glass, chemically strengthened to reinforce the thickness of thin glass, which is often used in chemically tempered glass products are mobile phone glass, display glass, the scanner glass glass,printer, plasma TV glass, chemically tempered also not necessarily can onlytoughened glass thickness thin, high glass can also make good tempered, its advantage is tempered and flexible, suitable for different size, different thickness,different shapes of glass processing, in the range of 0.3-19 mm glass, toughenedits surface more than physical smooth, light transmittance is better, and noexplosion occurred the phenomenon.
