In the decorative electroplating process of zinc alloy die-castings, after the electroplating factory pre-deposits copper and coke copper on the workpiece, an acid bright copper plating treatment is required. The use of acid bright copper plating can enhance the brightness of the product. By taking advantage of the leveling property of the acidic bright copper plating solution, the fine pores and scars remaining on the workpiece after grinding and polishing can be filled. So, what matters should be noted during the operation process? What kind of acid copper plating brightener should be chosen then?
When zinc alloys are electroplated in an acid bright copper plating solution, there is a tendency for chloride ions to decrease. Electroplating plants should pay attention to replenishing them.
For complex workpieces with deep convexity and convexity, especially those without holes, due to the inability to promptly eliminate air bubbles within the holes, copper cannot be plated or the copper coating is very thin. In acid copper plating solutions, there is a corrosion phenomenon, and loose copper powder adheres to the surface of the workpiece, resulting in burrs or roughness on the coating. Therefore, it is necessary to avoid holes as much as possible and use acidic copper plating brighteners with good positioning performance.
When electroplating with acid copper solution at room temperature, the evaporation of the solution is small. Fill an empty anode bag with solid copper sulfate, suspend it on the edge of the tank and immerse it in the solution. The copper sulfate can be naturally dissolved and replenished.
Bigely acid copper plating brightener Cu-510 can achieve a mirror-like bright copper plating layer. It is suitable for high-filling copper plating on bathroom zinc alloy die-castings. Even in the low zone, it can obtain a copper plating layer with good brightness, which solves the problem of poor positioning performance.
