Surface Treatment Requirements:
Process Flow: Raw Material → Degreasing → Rust Removal → Surface Adjustment → Phosphating → Drying → Electrostatic Powder Coating (Color of Choice) → Curing → Packaging
2. Surface treatment uses electrostatic powder coating with epoxy resin, with a film thickness of 60~80 micrometers.
3. The adhesion of electrostatic powder coating meets the 0-grade requirement of GB9286.5-88 standard.
4. Hardness (wear resistance) is over 100 times that of ordinary nitrocellulose paint, meaning it withstands a 2H pencil test without any scratches.
5. Corrosion Resistance (Hydrochloric Acid Test) GB1771-91 exceeds 500 hours.
