Silver sand Anodizing profiles

The purpose of sandblasting before oxidizing aluminum alloy profiles is to remove the oxidized layer and other impurities from the surface, so that the surface is well-prepared for subsequent oxidizing treatment. The following are the general steps for sandblasting in our factory:

Preparation:

Prepare the sandblasting equipment, including sandblaster, abrasive, compressed air, etc.

Ensure that the work area is well ventilated to prevent dust and grit from flying while wearing personal protective equipment such as respiratory masks, protective eyewear and gloves.

Clean surfaces:

Clean aluminum profiles thoroughly to remove oil, dust and other contaminants from the surface. Cleaning can be done with detergents and solvents.

Sandblasting:

Place the cleaned aluminum alloy profile in the sandblasting machine and adjust the parameters of the sandblasting machine, such as sandblasting pressure, grit flow, etc., to achieve the ideal sandblasting effect.

Use appropriate abrasives to sandblast the aluminum alloy profile. Commonly used abrasives include aluminum oxide sand, glass beads, etc. The specific selection depends on the requirements of the treatment and the characteristics of the surface.

When sandblasting, pay attention to controlling the distance and angle of the sandblasting gun to ensure even treatment of the surface and to avoid damage to the profile or formation of an uneven surface.

Cleaning and inspection:

After completing the sandblasting treatment, remove the aluminum alloy profile from the sandblasting machine and clean it up to remove any residual grit and dust.

The treated aluminum alloy profile is inspected to ensure that the surface treatment meets the requirements and there are no obvious defects or untreated parts.

Oxidizing treatment:

After the sandblasting treatment is completed, oxidation treatment can be carried out immediately to prevent the oxidized layer from being generated again. The specific steps of oxidation treatment can be determined according to the subsequent treatment process.

These steps are the basic process of sandblasting treatment before oxidation of aluminum alloy profiles in general. In practice, they can be adjusted and optimized according to the specific situation to ensure that the quality of the final product meets the requirements.
