1. Surface pretreatment: Before painting, the metal surface needs to be thoroughly cleaned to remove impurities such as oil stains and dust. Next, degreasing treatment is carried out to remove oxides and dirt from the metal surface, improving the adhesion of the coating.
2. Choose the appropriate coating: The selection of coating is very important for metal surface coating. Common coatings include solvent based coatings, water-based coatings, and powder coatings.
3. Coating technology: The main process of metal surface coating technology includes preparation work, surface treatment, coating, and curing. During the coating process, it is necessary to control the thickness of the coating to ensure its uniformity and performance.
