Anodizing champagne door aluminum profile

The manufacturing process of aluminum alloy profile oxidation champagne is a complex and precisely controlled process involving multiple steps. The following is a detailed manufacturing process:

1. Surface pretreatment

Cleaning: Use alkaline or acidic cleaning agents to remove surface oil, dust and other contaminants. Ensure that the surface is clean and free of impurities.

Degreasing: Further use degreasing agents to remove grease on the surface.

Water washing: Rinse the aluminum alloy surface thoroughly with clean water to remove the cleaning agent residue.

Pickling: Use acidic solution for pickling to remove the oxide layer and surface impurities and increase surface activity.

Water washing again: Rinse with water again after pickling to ensure that there is no acid residue on the surface.

2. Anodizing

Anodizing tank: Immerse the aluminum alloy profile in the anodizing tank, and the tank liquid is usually a sulfuric acid solution.

Electrification: Apply electricity to the aluminum alloy profile to make it an anode, and the current density and voltage are adjusted as needed. The oxidation time is usually controlled at 20-30 minutes.

Oxide film formation: A dense oxide film is formed on the surface of the aluminum alloy through electrochemical reaction.

3. Coloring treatment

Electrolytic coloring: Put the oxidized aluminum alloy profile into the electrolytic coloring tank, and deposit metal particles in the oxide film by powering on and metal salts in the electrolyte (such as tin salts, nickel salts, etc.) to form a champagne color.

Control current and time: Strictly control the current density and coloring time to ensure uniform color.

Dye coloring (optional): Sometimes organic dyes are used for coloring. Select appropriate dyes and process parameters according to needs.

4. Sealing treatment

Hot water sealing: Immerse the colored aluminum alloy profile in boiling water, and close the micropores in the oxide film through the action of high-temperature water.

Cold water sealing (optional): Use the cold water sealing process, and usually add chemical additives (such as nickel salts, nickel nitrate, etc.) to enhance the sealing effect.

5. Post-processing

Drying: Dry the aluminum alloy profile after sealing to ensure that there is no moisture residue on the surface.

Surface treatment: Perform surface polishing, spraying and other treatments as needed to improve the appearance quality and corrosion resistance.

Quality inspection: Use spectrometers, colorimeter and other equipment to inspect the quality of the product to ensure uniform color and qualified oxide film thickness.

6. Packaging and storage

Packaging: Use appropriate packaging materials and methods to prevent damage during transportation and storage.

Storage: Store the product in a dry, ventilated environment to avoid corrosion and contamination.

Through the above steps, high-quality oxidized champagne aluminum alloy profiles can be produced. Each step requires precise control of process parameters and strict implementation of process specifications to ensure product color consistency and oxide film performance.
