An inorganic enamel material with superior chemical corrosion resistance (to acids, alkalis, and wastewater) and aging resistance was successfully developed through optimized enamel formulation design, specifically for enamel-assembled tanks in biomass energy applications. In accordance with the design specifications for assembly tanks, high-strength steels suitable for double-side enameling were selected. Laser cutting was employed for precise hole perforation. The surface was then subjected to sandblast, followed by enameling and firing. The enamel-assembled tank has the characteristics of excellent acid, alkali and sewage resistance, outstanding bond and a long lifetime, making it an ideal corrosion-resistant storage and transportation equipment solution in the field of biomass energy engineering.
