Disadvantage of tempered glass: 1 glass and steel post can no longer be cut, and processed glass door, only in front of the glass on steel processed to the desired shape, and then the steel processing. 2 tempered strength, although stronger than ordinary glass, but the glass in the temperature changes when there is a possibility blew (his own rupture), while ordinary glass blew possibility does not exist. 3 tempered glass surface is uneven exist tempered glass, with a slight thinner. Thinning because after glass melt soften, after strong wind it quickly cooled, it inside gap smaller 12mm glass crystal glass, the pressure becomes large, steel and glass in the front than in thinner steel . Under normal circumstances 4-6MM tempered thin glass after glass window 0.2-0.8MM, 8-20MM toughened glass after thinning 0.9-1.8MM. To determine the specific level according to the device, which is also the reason mirror glass can not be done. Flexible glass is much larger than ordinary glass, a 1200mm × 350mm × 6mm tempered glass, can occur by the force of the deflection of up to 100mm, when the external force is removed, still restitution, but there can be only ordinary glass bending a few millimeters. Good thermal stability, thermal shock when the subject, less prone to burst is another characteristic of tempered glass. This is because stress can offset part of the glass so that the tensile stress generated due to thermal shock. Tempered glass thermal shock, the maximum safe operating temperature of 288 ℃, can withstand 204 ℃ of temperature changes. Glass window | Dongying glass | Yaohui trusted by Jinan Glass Co., Ltd.
