Manufacturing  process of glass

 

Glass is an amorphous inorganic non-metallic material, which is usually made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, and a small amount of auxiliary raw materials. Its main components are silica and other oxides. The chemical composition of ordinary glass is Na2SiO 3, CaSiO 3, SiO 2 or Na2O CaO 6SiO 2, etc. The main component is silicate compound salt, which is an amorphous solid with irregular structure. Widely used in buildings, used for wind insulation and light transmission, belongs to mixtures. Others are colored glasses mixed with oxides or salts of certain metals, tempered glasses made by physical or chemical methods, etc. Some transparent plastics, such as polymethyl methacrylate, are sometimes called plexiglass.
