Abstract
Disclosed is a chromate-free passivation treatment process for aluminum profile material. The chromate-free passivation treatment process specifically comprises the steps of ash removal, deslagging rinsing, oil removal degreasing, activation degreasing, rinsing, hot dip galvanizing, rinsing, chromate-free passivation and rinsing. The process is simple and orderly. Degreasing and galvanizing are added based on a traditional process, so that the life of the profile material is prolonged, and the surface strength of the profile material is increased; the profile material is oxidation-resistant for a long time; meanwhile, a layer of thin film is formed on the surface of the profile material, and the thin film protects the surface of the profile material effectively, so that the profile material is oxidation-resistant and corrosion-resistant. The process makes the chromate-free passivation treatment on the profile material more perfect.
