The treatment steps before stainless steel Etching are the key links to ensure the quality and effect of Etching. The following is a brief introduction to the pre-treatment steps of stainless steel Etching.
First of all, cleaning is the first step in the pre-treatment of stainless steel Etching. The purpose of this step is to remove grease, dirt and other impurities on the surface of stainless steel to ensure that the Etching liquid can evenly and fully contact the surface of stainless steel. Cleaning is usually done by solvent cleaning or alkaline cleaning agent cleaning to ensure thorough cleaning of the surface.
Secondly, grinding and polishing are important steps in the pre-treatment of Etching. Through grinding and polishing, the oxide layer, scratches and other unevenness on the surface of stainless steel can be removed to make the surface smoother and flatter. This helps to improve the accuracy and clarity of Etching and make the pattern more delicate and beautiful.
Next, degreasing is also essential. Degreasing can further remove grease and residues on the surface of stainless steel to prevent them from interfering with the action of Etching liquid during Etching. Degreasing usually uses organic solvents or alkaline degreasing agents to ensure thorough removal of grease.
Finally, the preparation of the anti-corrosion layer is the last step of Etching pre-treatment. The function of the anti-corrosion layer is to protect the parts that do not need Etching and prevent Etching liquid from damaging them. The anti-corrosion layer usually uses materials with good corrosion resistance, such as ink, paint, etc. When making the anti-corrosion layer, it is necessary to ensure that it has good bonding with the stainless steel substrate and the pattern lines are clear and accurate.
In summary, the processing steps before stainless steel Etching include cleaning, grinding and polishing, degreasing, and the preparation of the anti-corrosion layer. The strict implementation of these steps can ensure the quality and effect of Etching and lay a solid foundation for subsequent Etching processing.
