What are the surface treatment methods for aluminum profiles?
Anodizing ▲

Anodizing. This is the process of connecting aluminum profiles to the anode of a DC power supply and conducting redox reactions in sulfuric acid or other electrolyte solutions to form a layer of aluminum oxide (Al2O3) film on the surface of the aluminum profile. This film has anti-corrosion, wear-resistant, and decorative effects.

Powder spraying & Mill finish ▲

Powder spraying. Powder spraying is the process of using electrostatic adsorption to spray thermosetting saturated polyester powder onto the surface of aluminum profiles, then heating and curing to form a protective film. This method has excellent corrosion resistance and the ability to withstand acid, alkali, and salt spray.

Wood grain transfer ▲

Wood grain transfer. This is a relatively new processing method that transfers the texture of wood to the surface of aluminum profiles through a special process, giving aluminum profiles the texture and texture of wood.

Electrophoretic painting. Electrophoretic painting is a surface treatment method that uniformly adheres the surface of profiles to water-soluble coatings through ion adsorption on the basis of anodizing. It has the advantages of a full, uniform, flat, and smooth coating.

Fluorocarbon spraying. Fluorocarbon spraying is the use of electrostatic spraying to spray fluorocarbon coatings (a weather resistant coating) onto the surface of aluminum profiles, and then heat and cure them. This method has excellent weather resistance, chemical resistance, and corrosion resistance.

These surface treatment methods each have their own characteristics and applicability, and suitable treatment methods can be selected according to different needs and occasions.
