Hydropower sluice steel gates operate under extremely complex conditions: long‑term alternating immersion and air exposure, river silt scouring, water‑borne chemical medium erosion. Conventional anti‑corrosion coating wears rapidly under silt impact, requiring frequent overhaul for water‑conservancy projects.
FLDC four‑layer glass‑flake heavy‑duty anti‑corrosion coating system for sluice steel gates:
- Epoxy zinc‑rich primer: cathodic anti‑rust protection for steel substrate
- High‑solid epoxy glass‑flake intermediate coat: core barrier against water and silt
- Abrasion‑resistant epoxy thick‑film reinforcing coat (splash zone enhanced layer)
- Water‑resistant aliphatic polyurethane topcoat
Core Advantages:
✅ Adapt long‑term water‑immersed & air‑exposed alternating working condition
✅ Resist river‑silt mechanical scouring and abrasion
✅ Good performance under freshwater and slightly corrosive river‑water medium
✅ Reduce overhaul frequency, extend gate service life for water‑conservancy projects
✅ Large‑container bulk‑packaging fit large‑scale hydropower bidding procurement
