Fields aplikasi:
Municipal drinking water supply pipes.
Proses Aplikasi:
Electrostatic spraying, dip coating, etc.
Kewaspadaan:
The steel pipe surface should be free of oil and moisture; the surface treatment quality should reach Sa2 1/2 level (GB/T 8923); the anchor pattern depth should be 50-90 mm; dust and abrasives on the steel pipe surface should be blown clean. Preheating temperature should be controlled between 180-230°C.
The product should be stored in a well-ventilated, dry indoor environment with a temperature below 30°C, away from heat sources, corrosive chemicals, and chemical solvents, and protected from strong light exposure. The stacking height should not exceed four layers. Avoid long-term pressure and ensure the packaging box is sealed to prevent caking and moisture, which can affect fluidization performance.
To ensure thorough curing of the epoxy coating and better anti-corrosion performance, it is recommended to preheat the steel pipe surface to above 170°C to improve the curing completion rate.
Do not mix with other anti-corrosion powders or recycled powders. Thoroughly clean the spraying equipment when changing colors to ensure drinking water safety and compliance with health standards.
