What is the procedure for the process of copper plating on stainless steel plates?
The stainless steel plate copper plating process currently generally has two processes.
1. The first is vacuum plating. Electroplating is a process in which a metal film is adhered to the surface of a metal or other material by electrolysis. It can prevent corrosion, improve wear resistance, electrical conductivity, light reflectivity and enhance aesthetics.
The process flow is: spraying a primer on the material and then plating. Since the material is a plastic part, air bubbles, organic gases are left in the injection molding, and moisture in the air is taken in when placed. In addition, since the surface of the plastic is not flat enough, the surface of the directly electroplated workpiece is not smooth, the gloss is low, the metallic feeling is poor, and bubbles, blisters and the like may occur. After spraying a primer, a smooth and flat surface is formed, and the generation of bubble blisters in the plastic itself is eliminated, so that the electroplating effect is exhibited.
2, the second is water plating is currently the most used, stainless steel water plating process is: in the aqueous solution does not rely on the external power supply, relying on the reducing agent in the plating solution for chemical reduction reaction, so that the metal ions are continuously reduced A process for forming a metal plating on a self-catalyzing surface. Its processing process firstly removes wax and degreasing treatment of the plated workpiece. After activation, the alkali copper is electroplated first. The plating time is about 10 minutes. After the tank is removed, it is washed, neutralized and activated, and then copper bright plating is performed. The plating time is more than 20 minutes. When the plating layer is thick enough, the bath is washed, activated, and directly plated with nickel and black. The plating time is uniform on the surface of the workpiece, and then washed, dried, and processed. The copper brightly plated workpiece can also be blackened after being washed with water, generally immersed in a 5% potassium sulfide aqueous solution, repeatedly flipped, and when the surface of the workpiece is black or brown, the workpiece is taken out, washed, dried, and waited. machining. Then, the workpiece plated with black nickel and gun color or blackened is polished with a nylon wheel, and the weight of the polishing is determined according to the requirements of the patina. When the workpiece reaches the desired effect, the electroplating varnish is sprayed, that is, we say No fingerprint processing and then drying the package is fine.
