We know that the theoretical strength tempered glass windows, the glass than before actual high two orders of magnitude, it is possible to improve the mechanical properties of the glass by heat treatment. Refers to the heat treatment of the glass at the glass transition temperature and the heat treatment temperature between the softening carried out. In the heat treatment process, structure and properties of the glass tends to occur a significant change, the glass transition from one state to another, with the glass composition can have very different properties. Each piece has a glass factory is 3C, 12mm tempered glass, that is, the angle between two layers of steel on the two pieces of glass have marked 3C, 3C is tempered into a glass, 5mm tempered glass, with something that can not afford to do Shandong glass, tempered glass is not really to demonstrate (see side glass is not a wavy line wavy line is ~~~ steel flower glass, if it is very straight --- that is, ordinary glass, if there are scratches, certain requirements to replace the glass surface due process or formula plus scratches caused by improper operation, bombing mouth, dark burst edges and other defects, could easily lead to stress concentration or cause glass blew. distinction tempered glass door glass and ordinary glass, Yaohui Glass quality assurance (online consultation), tempered by the Jinan Shandong Yaohui Glass Co., Ltd. Jinan Yaohui Glass Co., Ltd. (www.jyhhc.com/) Shandong Jinan, architectural glass leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
