The pretreatment work before continuous electroplating mainly includes the following steps:
1. Degreasing treatment: use alkaline or acidic degreasing liquid to remove grease, wax and other impurities on the metal surface to ensure the adhesion and quality of the plating layer.
2. Water washing treatment: Put the metal parts that have been degreened into water and clean them completely to remove the degrease liquid and other residues.
3. Pickling treatment: The metal parts that have been washed with water are placed in an acidic solution for pickling treatment to remove oxides, rust and other impurities on the metal surface, so that the metal surface is smooth and smooth.
4. Washing again: Put the pickled metal parts into water for complete cleaning to remove the residual acid solution and other impurities.
5. Activation treatment: Put the metal parts that have been washed with water into the activation liquid for activation treatment to increase the adhesion and quality of the plating layer.
6、continuous electroplatingTreatment: Put the activated metal parts into the plating tank for treatment, so that the metal surface forms a uniform plating layer to improve the appearance quality and corrosion resistance of the product.
7. Washing again: Put the treated metal parts into water for complete cleaning to remove residual plating solution and other impurities.
8. Drying treatment: The metal parts that have been washed with water are dried to make the surface dry and smooth for the next processing.
In short, the pretreatment before continuous electroplating is very important, which can ensure the adhesion and quality of the plating layer, thereby improving the appearance quality and corrosion resistance of the product.
