The maximum temperature difference between the general case of fire appeared in the glass edge and an intermediate portion, when the glass is broken glass from the edges begin to improve the glass edge to withstand the stress of temporary measures is a monolithic fire-resistant glass manufacturing and installation of the key. After high-strength steel and glass blew phenomenon exists, in the production of hot-dip treatment is generally done. Heating temperature, heating time than normal glass high of about 10%, this will fully eliminate the residual stress in the glass, and be conducive to the formation of high strength steel. Steel process plate glass can be divided into physical steel technology and chemical tempering process two glass factories, steel glass technology means through ion substitution way to ionic radius larger potassium ion replacing the glass surface layer of the sodium ions 12mm steel glass, the glass surface layer have a "congestion" molecular structure, resulting in 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 tempered glass 8mm, the surface layer of the stress distribution, consistent stress magnitude, when it is broken, the entire piece of glass broken into irregular pieces of mesh, this product is called a full glass.
