Glass is a brittle material typical window glass, a variety of reasons, the glass surface covered with micro-cracks. When the glass surface by the tensile stress, micro-cracks began to expand, and finally from the surface rupture, causing damage to the glass. If you can eliminate the effects of these microcracks tempered glass, glass strength 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 12mm tempered glass bridge, forcing microcracks orientation. The actual strength of annealed glass microcracks due to uncertainty there is often considerable dispersion of 5mm tempered glass, and the actual strength of tempered glass is relatively stable. Good performance monolithic fire-resistant glass, simple installation structure. Monolithic fire glass through physical steel processing, has all the properties of tempered glass, glass products are safe. A product is good optical performance, transmission and ordinary float glass; high-strength glass B is 6 times that of ordinary float glass; C physical and chemical tempering steel combination of methods, potassium ions penetrate the surface of the glass so that the micro- crack greatly reduced, the mechanical strength of glass and thermal shock strength is greatly improved.
