The difference between anode oxidation and chemical oxidation of aluminum profiles

Aluminum profile oxidation method has anode oxidation and chemical oxidation mode, But the chemical oxidation method of the oxidation film is relatively thin, so it is not very commonly used.

The differences are as follows:

Anode oxidation is the placement of industrial aluminum profiles in acid-base solution, the two ends of aluminum through high-voltage direct current, so that it has an electrolytic reaction and the aluminum profile surface forms a dense transparent oxide film layer.

Chemical oxidation does not require power, only the aluminum profile is soaked in chemical potions so that the aluminum on the surface of the aluminum profile oxidation reaction to produce an oxide film.

1. Anode oxidation is an electrochemical reaction, and chemical oxidation belongs to a pure chemical reaction.

2. The anodized film is thick, can reach 10-15μ , chemical oxidation film is thinner, only 0.3 to 0.5μ .

3. The industrial aluminum profile after anode oxidation is not conductive, while the aluminum profile after chemical oxidation has good conductivity. Because aluminum profile anodized film is thick, alumina is insulated, so wrapped in the alumina film aluminum profile is also insulated.

The chemical oxidation film is very thin, it will not affect the conductivity of aluminum profiles, so chemical oxidation is also called conductive oxidation. Aluminum profile products with conductivity requirements generally will use the method of chemically oxidized.

4. Anode oxidation after the hardness and wear resistance of industrial aluminum profiles will also be improved, chemical oxidation will not change.

5.Anode alumina profiles resistant to dirt, easy to clean. The aluminum that conducts electrical alumina is not resistant to dirt and is easy to leave a handprint.
