Problems solved by technology

[0003] However, there are grease and dirt on the surface of plastic products before electroplating. If they are not cleaned, the quality of the electroplated workpieces after electroplating will be affected. It is difficult to completely clean the grease and dirt in the current process. pollution, which not only affects the progress of the process, but also prolongs the processing time

Abstract

The invention discloses an electroplating surface treatment technology combining electrolytic degreasing and acid pickling oil removal. The technology comprises the following steps that a workpiece needing to be electroplated is discharged; electrolytic degreasing is carried out in a solution; 100% tap water is adopted for carrying out spraying and washing; acid pickling oil removal is carried outin the solution; 100% tap water is adopted for carrying out spraying and washing; and the workpiece is soaked in the 100% tap water to be washed. According to the technology, electrolytic degreasingand acid pickling oil removal are combined, under cooperation of the flowing solution, fast oil dirt and scale can be removed, degreasing and oil removing in the flowing type solution are adopted, thespeed of removing dirt and oil is increased, and thus the dirt is removed more thoroughly.

Description

technical field [0001] The invention relates to a surface pretreatment method, in particular to an electroplating surface treatment process combining electrolytic degreasing and pickling degreasing. Background technique [0002] Plastic electroplating products have the advantages of light weight, good corrosion resistance, easy molding and metal organic solvent resistance, light resistance, metallic luster, thermal conductivity, electrical conductivity, electromagnetic shielding, and easy welding. They are used in automobiles, motorcycles, Widely used in hardware, electronics, communication and other industries. [0003] However, there are grease and dirt on the surface of plastic products before electroplating. If they are not cleaned, the quality of the electroplated workpieces after electroplating will be affected. It is difficult to completely clean the grease and dirt in the current process. Pollution not only affects the progress of the process, but also prolongs the ...
