The glass-lined equipment is made by coating the high silicon content enamel onto the surface of metal body and then firing them at high temperature ( ~ 900℃ ) in order to achieve a high adhesive strength of the enamel on the steel basic body. The glass-lined equipment, therefore, has high mechanical features and corrosion resistance. Substituting stainless steel and nonferrous metal equipment, the glass-lined equipment is widely used in fine chemical, pharmaceutical, dyestuff, pesticide, metallurgical and food industries. Corrosion resistance stability: very high corrosion resistance against inorganic acid, organic acid, organic solvent with different concentration and weak base, but not applicable to alkali, hydrofluoric acid, fluoride-bearing medium and phosphoric acid with concentration above 30% at temperature over 180℃. Thermal shock resistance: resistance to sudden cooling 110℃, resistance to sudden heating insulation performance: the enamel surface should be strictly tested at 20kv.
