In order to use the mobile phone more conveniently, therefore, the outer shell of the mobile phone adopts an aluminum alloy enclosure, which has the characteristics of being light, portable and hard. However, the aluminum profile shell is prone to oxidation and rust, which will lose its luster. At this time, it needs to be polished. Generally, there are three types of polishing, namely polishing, mechanical polishing, and electropolishing. In the process of polishing a car or ship, it is necessary to grasp the order, first perform mechanical polishing, then electropolishing, so that a bright luster can be achieved, and coloring can also be performed on the aluminum profile shell. The following is a brief analysis of the three major chemical polishing treatment methods for aluminum alloy enclosures.
1. Use chemical reaction to polish the aluminum alloy enclosure:
Using the characteristics of chemical reaction anodization, the anode of the power supply is attached to the aluminum oxide aluminum profile shell to achieve the polishing treatment effect.
2. Use electrolysis reaction to polish the aluminum alloy enclosure:
The use of chemical reactions for pre- and post-treatment processes can also be used as pre-treatment processes for chemical film formation such as phosphating and bluing. If the rust preventive passivation aqueous solution is dipped before painting, the aluminum oxide on the surface of the aluminum profile shell can be eliminated.
Three, use chemical reaction for electroplating polishing:
We can use chemical reaction to coat the aluminum alloy enclosure with electroplating effect to prevent oxidation, which can indirectly achieve the polishing effect.
The above four chemical aluminum alloy enclosure polishing methods are commonly used and economical methods, which can effectively remove the oxide layer of the aluminum profile shell and restore the original luster and texture.
