The chemical conversion treatment in the anti-oxidation treatment of the aluminum surface of
decorative aluminum extruded profile profiles causes the metal to contact with the specific corrosive liquid. Under certain conditions, the ions in the outer nuclear etched liquid on the surface of the aluminum material undergo chemical or electrochemical reactions to form on the surface. A layer of insoluble corrosion-producing film with good adhesion.
1, rare earth conversion coating treatment of
decorative aluminum extruded profile profiles: shows a good application before placing aluminum in a solution of chromate, manganate, acid salt, etc. for a few minutes to form a conversion film rare earth bonded well to the surface of the aluminum substrate. The conversion film shows good application prospects due to its excellent corrosion resistance and non-toxic and non-polluting characteristics in the process.
2. Organosilation treatment of
decorative aluminum extruded profile profiles: organosilylation treatment is a new type of metal surface protection technology developed in recent years. It is favored by people because it has no pollution and good resistance to treatment parts. The formation of the siloxane bond can greatly improve the adhesion of the surface polymer coating to the base aluminum, and also improve the corrosion resistance of the aluminum alloy.
3. Chemical anodization treatment of
decorative aluminum extruded profile profiles: At a certain temperature, a layer of anodizing film is formed on the surface of the rate part by chemical reaction, which is called green chemical anodization method. The generalized chemical anodization method includes a chemical anodizing film in which an anodizing agent such as dichromate is involved.
This method of
decorative aluminum extruded profile profiles does not require current flow. Electrochemical oxidation on the process is simple and low cost
