A brief discussion on four methods of polishing aluminum profile shells

With the progress of the times, various means of transportation have developed, such as airplanes, ships, cars and even household products, office furniture all use aluminum profile shells, which can be said to be used in many fields and are very widely used, and are closely related to people's lives. However, every year we have a lot of aluminum profile shells that are oxidized and lose their luster, and at this time they need to be polished.

There are three general polishing methods, namely polishing, mechanical polishing, and electropolishing. In the process of polishing cars or ships, we must grasp the order of priority, first mechanical polishing, then electropolishing, so that it can be bright and restore the past luster, and it can also be colored on the aluminum profile shell.

Here are five polishing methods to restore the past luster of the aluminum profile shell.

According to different usage requirements, we list five methods for treating the surface of the aluminum profile shell:

1. Anodizing, remove the aluminum oxide on the aluminum profile shell and perform effective polishing.

2. Electrolytic polishing, electrolytic polishing uses chemical reactions with electrolytic polishing as the anode and insoluble metal as the cathode to immerse in the electrolytic cell, pass direct current, dissolve the anodized aluminum, and the aluminum oxide disappears from the aluminum profile shell to restore the luster.

3. Chemical polishing can be used as a pre-treatment process for protective decorative electroplating, or as a pre-treatment process for chemical film formation such as phosphating blue. If the anti-rust passivation aqueous solution is immersed before painting, the aluminum oxide on the surface of the aluminum profile shell can be eliminated.

4. After the anodizing of the electrolytic reaction, the color is developed, and various colors are formed on the oxide film, and then the coloring is carried out, which depends on your requirements.

The above four are commonly used polishing methods, which are also relatively low-cost and highly operable. They can effectively remove aluminum oxide on the surface of the aluminum profile shell, achieve the effect of polishing, and restore the original gloss of the aluminum profile shell.
