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 a plastic electroplating product surface treatment process. The process comprises the following steps that materials are fed for a workpiece needing to be electroplated, electrolytic degreasing is conducted in a solution, 100% tap water is adopted for being sprayed and washing, acid pickling oil removal is conducted in the solution, the 100% tap water is adopted for being sprayed and washing, and the workpiece is immersed into the 100% tap water for being washed. According to the process, electrolytic degreasing and acid pickling oil removal are combined, stubborn oil stains and dirt can be removed under the cooperation of the flowing solution, the flowing solution is adopted for degreasing and oil removal, so that the decontamination and oil removal speed is increased, and decontamination is more thorough.

Description

technical field [0001] The invention relates to a surface pretreatment method, in particular to a surface treatment process for plastic electroplating products. 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 processing time. Contents of the inv...
