1. Surface treatment of industrial aluminum profile:

The surface treatment of industrial aluminum profiles is also called surface pretreatment, which uses physical and chemical substances to remove dirt on the surface of industrial aluminum profiles, leaving the aluminum profile body exposed, which is convenient for later oxidation treatment on the surface of industrial aluminum profiles.

2. Surface degreasing process:

The purpose of the degreasing process for industrial aluminum profiles is to remove industrial lubricating oil and anti-corrosion oil on the surface of industrial aluminum profiles, as well as dirt and impurities attached to the surface of the profiles, to ensure uniform alkali corrosion and the cleaning of alkali corrosion tanks, and to improve the quality of surface treatment of industrial aluminum profiles .

3. Acid etching process:

The surface acid etching process of industrial aluminum profile is to perform surface acid corrosion treatment after degreasing. The main purpose is to remove the oxide formed after the oxidation of other metal elements on the surface of industrial aluminum profile and the oxide film of the natural profile of the profile, making the surface bright silver.

4. Alkaline etching process:

The main purpose of the alkaline etching process of industrial aluminum profiles is roughly the same as that of the acid etching process. It removes the residual substances and degraded layers on the surface of the industrial aluminum profile during the oxidation process, and eliminates the scratches left on the surface during the extrusion process; industrial aluminum The alkali etching treatment on the surface of the profile plays a vital role in the overall quality of the surface.
