Alumina refineries run under high temperature, strong alkaline dust and acid waste gas all year round, which forms highly corrosive mixed medium on steel equipment. Conventional anti-rust coating fails rapidly under dual erosion of alkali dust and hot flue, especially tropical Africa & Southeast Asia alumina projects with severe atmospheric corrosion.
FLDC three-layer matched anti-corrosion system for alumina plant conveyors, furnace frames and waste gas pipelines:

1. Modified high-adhesion epoxy zinc-rich primer
2. High-solid alkali-resistant micaceous iron intermediate coat
3. Heat & acid dual resistant aliphatic polyurethane topcoat
   Core Advantages:
   ✅ Simultaneously resist high-temp alkaline powder and acidic flue gas
   ✅ Adapt tropical high temperature & high humidity mining climate
   ✅ Strong mechanical shock resistance for material conveying equipment
   ✅ Large tank industrial packaging fit smelter bulk procurement
   ✅ Pass mineral medium aging test for overseas mining tender
