As a commonly used plate in the construction industry and product manufacturing industry, aluminum plate not only has the advantages of good rigidity, high strength, light weight, but also has many types. Many friends in order to improve the decorative effect of aluminum panels, some friends like to paint on aluminum panels, so what aspects should be paid attention to when painting aluminum panels?
1. Before painting, the surface of the aluminum plate should be cleaned with solvent, especially the oil stains on the surface. This is to improve the adhesion of the primer, but it does not require sand blasting or polishing on the surface of the aluminum plate, which is very simple to handle.
2. When spraying primer on the surface of aluminum plate, it is necessary to first mix the epoxy primer and curing agent according to the correct ratio, then add an appropriate amount of epoxy diluent, and be sure to stir it evenly. Then, spray the mixture evenly on the surface of aluminum plate, which requires about two to three times of spraying, until the surface paint film reaches the specified thickness.
3. The aluminum plate manufacturer understands that after the primer on the surface of the aluminum plate is dried, it is necessary to spray the top coat. Before spraying the top coat, it is necessary to first mix the fluorocarbon paint and the curing agent according to the correct proportion, then add an appropriate amount of fluorocarbon paint thinner, and be sure to stir it evenly. Then, evenly spray the aluminum plate surface for about two to three times until the surface paint film reaches the specified thickness. After painting, if it is confirmed that the paint film is intact, the aluminum plate can be used normally after the paint layer is completely dried.
The above contents are precautions to be taken when painting aluminum panels, so as to achieve a more beautiful effect and ensure that the paint will not easily fall off after painting aluminum panels.
