Typically two-thirds of the overall use of glass as long as the heating time can be at or near the tempering temperature, followed by a slow rise glass, 12mm glass, after a period of time the internal temperature of the glass is mainly used for homogenization and stress relief, but this time is a must, Heze tempered glass, it helps to improve the quality and yield toughened glass. Lowe coated glass may be tempered in the furnace should be heated with forced convection system, glass roof, so as to ensure the quality of the quality of tempered glass. Steel process plate glass can be divided into two processes and chemical tempering process physical steel, steel glass technology means through ion substitution way to ionic radius larger potassium ion replacing the glass surface layer of sodium ions, the glass surface layer "congestion" produce molecular structure, causing the glass surface compressive stress layer in order to achieve the purpose of improving the performance of the glass. After the glass is heated to a temperature of steel, with the same intensity on the whole piece of cooling glass uniform cooling, thus obtained glass, the surface layer of the stress distribution, consistent stress magnitudes, glass doors, when it is broken, the whole piece glass broken into irregular pieces of mesh, this product is called a full glass. Glass door, Yaohui quality assurance (certification), Heze glass by Glass Co., Ltd. Jinan Yaohui. 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. Yaohui glass in Jinan leadership with the staff warmly welcome all inquiries negotiations to create the Jinan Yaohui glass better future.
