By steel processing, can effectively enhance the mechanical strength of the glass. Physical, chemical methods, so that the flat glass surface compressive stress layer, resulting in permanent stress glass evenly distributed, so as to obtain the deep processing of high-strength and high thermal stability methods of glass that is tempered glass. Physical steel, also known as hot steel method, the other is chemical tempering method. Physical tempered glass is the glass is heated to below the softening temperature before rapid and uniform cooling. Glass is typically brittle material, due to various reasons, the glass surface covered with micro-cracks. When the glass surface of the glass by the tensile stress 8mm, micro-cracks began to expand, and finally from the surface rupture, causing damage to the glass. If we can eliminate the influence of these micro-cracks, the strength of the glass can be greatly improved. Is generally believed that the number of micro-cracks annealed glass surface more disorderly distribution, and micro-cracks in the glass surface of steel stress, some bridging glass factory, forcing microcracks orientation. The actual strength of annealed glass microcracks due to uncertainty there is often considerable discrete, but the actual strength of tempered glass is relatively stable.
