What are the surface treatment technologies for industrial aluminum profiles?

Surface mechanical treatment of industrial aluminum profiles:

Mechanical treatment is one of the main methods for surface treatment of industrial aluminum profiles. Often, it plays an irreplaceable role. Mechanical treatment can generally be divided into: polishing (polishing, polishing, polishing Bull polishing), sand blasting (ball), polishing, rolling other methods. The exact method used depends mainly on the type, production method, initial surface state, required finishing level of industrial aluminum profiles. After surface treatment, industrial aluminum profiles can achieve the following goals.

(1) Provide good surface conditions to improve surface finishing quality. Severe appearance defects often occur in the production process of industrial aluminum profiles. Smooth glossy surfaces can be obtained through mechanical treatment, which provides good surface conditions for subsequent anodizing, chemical oxidation, other surface treatments, greatly improves the surface smoothness of industrial aluminum profiles.

(2) Improve the grade of industrial aluminum profiles. Although industrial aluminum profiles have formed a smooth surface during the production process, these products usually do undergo mechanical treatment before anodizing. However, with the development of society, users have put forward higher requirements, such as polishing, matte, satin. Extruded industrial aluminum profiles can be mechanically polished polished to eliminate defects such as extrusion lines even achieve a mirror like surface. If methods such as sanding, sandblasting, brushing are used for treatment, a matte sanded surface is formed. After other surface finishing treatments, the quality of the product is greatly improved, primary products can be upgraded to advanced products.

(3) Reduce the impact of welding. A large number of industrial aluminum welding parts are applied in industry. Due to the influence of high temperature solder, the microstructure of the weld metal changes the appearance color is inconsistent. Mechanical treatment can reduce the welding effect.

(4) Produce decorative effects. In aluminum handicrafts household daily necessities, most require aesthetics refinement. The decorative effect of stripes on aluminum sheets was studied through some special mechanical methods, such as sanding polishing.

(5) Obtain a clean surface. After being solved by mechanical equipment, industrial production of aluminum can obtain an oil-free, rust free, uniform color tone. The surface of the aluminum substrate can be thoroughly exposed for cleaning, the next step of processing process engineering construction can be carried out.
