塑料电镀工艺及其日常维护

Process for electroplating on plastics and its routine maintenance

介绍了适用于电镀的塑料种类,提出了一种塑料电镀的工艺,其流程主要包括:化学除油,粗化,中和,预浸,钯活化,解胶,化学镀镍,镀焦铜或者镀镍,镀酸铜,镀半光镍,镀高硫镍,镀全光镍,镍封和镀铬。给出了各工序的溶液组成及工艺参数。分析了漏镀、结合力不良、挂具上镀、麻点等故障的产生原因,并给出了解决方法。

The types of plastics suitable for electroplating were introduced. A process for electroplating on plastics was developed. The process flow consists of chemical degreasing, roughening, neutralizing, pre-dipping, palladium activating, peptizing, electroless nickel plating, pyrophosphate copper plating or nickel plating, acid copper plating, semi-bright nickel plating, high-sulfur nickel plating, full-bright nickel plating, nickel sealing, and chromium plating. The bath composition and operation parameters of individual procedure were given. The causes of some troubles, such as skip plating, poor adhesion, plating on racks, and pitting, were analyzed, and their countermeasures were presented.
