4-19mm gehärtetem Glas

In fact, tempered glass is a kind of prestressed glass. Theintensity of glass can usually be raised by chemical orphysical way, to form pressure on the surface of glass sothat glass must kill the surface stress before it bearsexternal force, which increases its carrying capacity, atthe same time improves its intensity of tension. Temperedglass has two main advantages. First, its intensity can beas several times as ordinary glasses: flexural strength is3-5 times and shock strength 5-10 times of ordinary glass.Intensity is raised, the same as security. Second, itssafer. The carrying capacity of tempered glass changes itsfriability. Even small pieces of broken tempered glass willnot have acute angle, which greatly reduced its harm tohuman body.Tempered glass is able to bear or endure urgent coldurgent hot property as 2-3 times as ordinary glass,commonly it can bear the difference in temperature ofover 150 LC, and has apparent effect to preventingexploding. Tempered glass is processed by ordinary flatglass or float glass. Preference or perfect ordinary flatglass and high-class or perfect float glass are required.There are two ways to process tempered glass: one is underspecial technological conditions, to precess tempered glassby quenching method or air patenting quenching method. Theother is to change the ingredients of glass surface by ionexchange technique, then to form a compressional stress onthe surface of glass.Features of Tempered Glass:. High shock strength (4 5 times than ordinary flat glass). High bending strength (5 times than ordinary flat glass). Good thermal stability. Smooth and clean. Transparent and curable. Tempered glass has another name of security glass, because the small pieces when it break are graininess without acute angle. Tempered glass is classified to flat and curved surface tempered glass by shape. Flat tempered glass is sorted to 4, 5, 6, 8, 10, 12, 15 and 19 mm. Curved surface glass is sorted to 5, 6 and 8 mm. By presentation quality, tempered glass can be classified to two kinds: premium grades and salable product. By the statues of splinters, three kinds.
