Glass enamel equipment is made by coating a high silicon content porcelain glaze on a metal surface, and then firing it at 950 ℃ to make the porcelain glaze tightly adhere to the surface of the metal iron body. Therefore, it has the dual advantages of chemical stability similar to glass and metal strength.
Glass lined equipment is widely used in industrial production and scientific research such as chemical, pharmaceutical, dye, pesticide, organic synthesis, petroleum, food manufacturing, and national defense industries for reactions, evaporation, concentration, synthesis, extraction, polymerization, saponification, mineralization, chlorination, nitration, etc., to replace expensive stainless steel and non-ferrous metals. Corrosion resistance: It has strong corrosion resistance to various concentrations of inorganic acids, organic acids, organic solvents, and weak bases. But it is not suitable for strong alkaline, hydrofluoric acid, and fluorine-containing ion media, as well as phosphoric acid with a temperature greater than 180 ℃ and a concentration greater than 30%.
