What are the main features of glass-lined equipment (enameled equipment)?

　　1, corrosion resistance: resistant to various concentrations of inorganic acids, organic acids, organic solvents and weak alkalis and other media corrosion. But for hydrofluoric acid and fluoride ion-containing media, temperature higher than 180 ℃ concentration greater than 30% of concentrated phosphoric acid and strong alkaline media is not applicable.

　　2, impact resistance: mechanical impact resistance is greater than or equal to 220 × 10- 3J (standard sample). Use should be avoided when the impact of hard objects.

　　3, insulation: porcelain surface through the 20,000-volt high-voltage test rigorous inspection.

　　4, temperature resistance: temperature resistance to rapid changes in temperature ---- cold shock 110 ℃, hot shock 120 ℃ use temperature 0 ℃ ~ 120 ℃.

　　5, surface finish: glass-lined surface smooth and clean, not easy to bond materials, easy to clean and discharge; isolation of metal ions, no metal ions contaminate the medium, to ensure that the medium quality, flavor, color and lustre are not affected, especially for food and beverage industry.

　　6. Abrasion resistance: good, no obvious scratches (ZB/TG94006 standard).

　　It is because of the above characteristics of glass-lined equipment, glass-lined equipment applications are as follows: glass-lined equipment is widely used in the chemical industry, pharmaceuticals, dyestuffs, pesticides, organic synthesis, petroleum, food manufacturing and the defense industry and other industrial production and scientific research, reaction, evaporation, concentration, synthesis, extraction, polymerization, saponification, mineralization, chlorination, nitrification, etc., in place of expensive stainless steel and non-ferrous metals.
