Punched aluminum veneer, as a widely used material in fields such as architectural decoration, billboards, curtain walls, etc., its surface treatment method is also an important aspect. Oxidation treatment is one of the common surface treatment methods. The characteristics of oxidation treatment for punched aluminum veneer will be introduced from the following aspects.

1. Principle of oxidation treatment

Oxidation treatment is a surface treatment method that improves the corrosion resistance and wear resistance of punched aluminum veneer by forming a dense oxide film on its surface. Specifically, oxidation treatment utilizes chemical reactions to oxidize free radicals on the surface of aluminum into stable compounds, forming an oxide film to protect the aluminum surface.

1. Characteristics of oxidation treatment

(1) Strong corrosion resistance: Oxidation treatment can form a dense oxide film on the surface of punched aluminum veneer, thereby improving its corrosion resistance and effectively resisting the erosion of corrosive media such as acid and alkali.

(2) Good wear resistance: Oxidation treatment can form a high hardness oxide film on the surface of punched aluminum veneer, thereby improving its wear resistance and effectively resisting scratches, wear and other damages.

(3) Rich colors: Oxidation treatment can prepare oxide films of different colors according to different processes and treatment conditions, thus meeting different decorative needs.

(4) Easy to clean: The oxide film formed by oxidation treatment has good self-cleaning performance, which can effectively prevent dirt and dust from adhering, making it easy to clean and maintain.

(5) Environmental Protection and Health: The chemicals used in the oxidation process have minimal impact on human health and the environment, making it a relatively environmentally friendly and healthy surface treatment method.

1. How to carry out oxidation treatment

In order to carry out effective oxidation treatment, the following steps need to be followed:

(1) Cleaning: Before conducting oxidation treatment, it is necessary to clean the punched aluminum veneer to remove surface oil stains and impurities.

(2) Anodizing: Place punched aluminum veneer as an anode in an electrolytic cell and apply direct current for electrolytic reaction to generate a dense oxide film on its surface.

(3) Water washing: Place the punched aluminum veneer after anodizing treatment into water for water washing to remove residual electrolyte and impurities on the surface.

(4) Dyeing: If it is necessary to dye punched aluminum veneer, the dyeing operation can be carried out after washing with water to obtain surface effects of different colors.

The oxidation treatment of punched aluminum veneer is one of the commonly used surface treatment methods, which has strong corrosion resistance and wear resistance characteristics. By implementing reasonable operational procedures and precautions, the quality and efficiency of oxidation treatment can be improved to meet the needs of different occasions.
