Global thermal power plants are upgrading denitrification facilities in 2026. SCR denitrification reactors and auxiliary flue equipment run continuously at 180‑240℃, suffering dual corrosion of high‑temperature sulfur‑containing flue gas and ammonium salt crystal deposition. Ordinary high‑temperature paint cracks and peels quickly under ammonium salt crystallization erosion, bringing frequent shutdown maintenance losses for power enterprises.
FLDC custom‑made three‑layer OM‑5 anti‑corrosion system dedicated for SCR denitrification steel structures:
- OM‑5 high‑temperature anti‑rust primer (continuous resistance up to 250℃)
- OM‑5 ammonium‑salt‑resistant intermediate coat, block crystal medium penetration
- OM‑5 heat‑resistant weatherable topcoat for outer casing
Core Advantages:
✅ Stable performance under long‑term 240℃ operating temperature
✅ Resist sulfur‑containing flue gas & ammonium salt crystal corrosion
✅ Excellent thermal‑shock resistance, no peeling under frequent temperature fluctuation
✅ Strong adhesion on high‑temp carbon steel reactor shell
✅ Meet thermal power plant anti‑corrosion acceptance standards
