The glass or glass products through physical or chemical means, and the glass surface layer permanent stress uniformly distributed, 12mm tempered glass, thereby obtaining a processing method of high strength and high thermal stability is called tempered glass. The glass is heated to a certain temperature, and then the glass in accordance with the requirements of rapid cooling rate, so that the glass have a great permanent internal stress, tempered glass window, you can make the mechanical properties of silicate glass has been greatly improved, this approach called glass physical steel (or hardening). After the glass is heated to a temperature of steel, with the same intensity on the whole piece of cooling glass uniform cooling, Texas tempered glass, tempered glass thus obtained, the surface layer of the stress distribution, consistent stress magnitude, when it is broken, the whole glass broken into irregular pieces of mesh, this product is called a full glass. Steel stress value between 69 ~ 140MPa, commonly referred to as glass is such a product. Nature through flat steel processing float glass compared with ordinary float glass, its mechanical strength and thermal stability are greatly improved. 12mm tempered glass, tempered glass, Texas, Yaohui glass preferred by Jinan Glass Co., Ltd. Yaohui. Jinan Yaohui Glass Co., Ltd. (www.jyhhc.com/) strong, credible, in Jinan, Shandong architectural glass industry has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Jinan Yaohui into the brilliant glass and you work for a better future!
