How to deal with after etching？

1. Cleaning of etching parts

After the etching is completed, the etching parts should be washed in time. If necessary, use the diluted neutralization solution to neutralize it, because the etching solution is a very corrosive liquid. If it is residual on the surface of the etching workpiece, it will cause corrosion damage or discoloration of etching products in the future, so the process of washing is very important and must be paid attention to.

2. Clearance of corrosion resistance layer

After the etching part is cleaned, it should be dried after cleaning, and then removes the protective coating in the most effective way. If it is pasted with a pasted organic film, it can be peeled directly; Clear.

3. Surface precision

The etching parts can be superficial according to the needs and design requirements. If the surface is required, the electrolytic polishing can be performed. On the one hand, the residues such as anti -corrosion materials can be completely removed. In addition, increase the brightness of the surface by polishing. If you need flat or matte, matte treatment is used.

4. Surface passivation or coloring

The etching components used in the project such as etching text or patterns of the inner cavity of the plastic mold, and the surface should be passivated or protective after etching. Because these steel materials or copper, stainless steel, etc. are easy to oxidize and rust. For products used in decoration, coloring or coating processing according to the product requirements and needs. The coloring treatment is mainly to use chemical coloring, electrolytic coloring and other methods to make the eroded products coloring, increase the color and effect of decorative decoration, can perform electroplating decorative plating layers, or paint various colored paint, which becomes a colorful color decoration.
