钢化玻璃

Float glass is heated to the softening point, then rapidly cool the glass surface. so that the compression distirbute in the glass surface.It is the tempered glass via the two step. Advantage: (1) high mechanical strength:6 mm thick tempered glass can withstand the attack of the weightof 227grams of glass balls at a distance of 2.5 meters high. (2) thermal shock resistance:Tempered glass can be as -40. To 327. C, rapid temperature changes, the glass will not be broken (3) good safety performance:When tempered glass is struck and broken,the fragment is usually in granular form and hurt no body.
