Tempered glass

Abstract

The invention relates to a tempered glass which is prepared from the following raw materials in parts by weight: 6-10 parts of waste glass, 5-10 parts of calcite, 5-7 parts of borax, 3-8 parts of clarifier, 7-10 parts of bauxite, 4-10 parts of titanium dioxide, 3-9 parts of chromic nitrate, 6-11 parts of potassium permanganate, 4-9 parts of chalcanthite, 3-6 parts of barium hydroxide, 4-11 parts of potassium silicate, 5-10 parts of silicon dioxide, 7-9 parts of aluminum oxide and 4-9 parts of bismuth oxide. The tempered glass has the advantages of favorable strength, favorable hardness and low possibility of spontaneous explosion, and can not hurt the human body.

Description

technical field [0001] The invention relates to a tempered glass. Background technique [0002] Tempered glass is obtained by cutting ordinary annealed glass into the required size, then heating it to about 700 degrees close to the softening point, and then cooling it quickly and uniformly. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of glass, chemical or physical methods are usually used to form compressive stress on the glass surface. Wind pressure, cold and heat, impact, etc. However, the existing tempered glass cannot meet the requirements of use, and there is often a phenomenon of self-explosion. Therefore, people expect to obtain tempered glass with better performance. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the problem to be solved by the present invention is to provide a tempered glass that has good strength and hardness, does not cause harm to the human body, and has a low possi...
