In the process of using zinc-nickel alloy natural color passivator, when there is a problem with the passivation film, such as blue passivation film, is this caused by the problem of passivator? Actually, it's not. Maybe it's the plating solution.
Zinc-nickel alloy plating is a widely used metal surface treatment process that deposits an alloy layer of zinc and nickel on a metal surface through an electrochemical reaction. This alloy layer not only combines the characteristics of both metals, nickel and zinc, but also shows good performance advantages, making zinc-nickel alloy plating especially favored in the industrial field.
ABS plastic plating products are a variety of products in which a metal film is plated on the surface of an ABS plastic product through a specific plating technique.ABS plastic plating offers many of the advantages of metal, such as a metallic sheen, improved chemical and physical durability, and improved appearance and texture, while maintaining the lightweight and cost-effectiveness of plastic.
What is colloidal palladium used for in the plastic plating process? Some people may say that colloidal palladium is used for activation. Then if you ask further, why is it necessary to carry out the activation process in the plastic plating process? It is estimated that some people will not be able to answer. This issue of the article we will take stock of the logic.
The service cycle of electroless nickel plating solution refers to the length of time that the solution can be effectively used, during which the solution can maintain its chemical properties and the quality of the coating. This cycle is affected by a number of factors, including the initial formulation of the solution, the amount of loading, the level of maintenance and management, and the quality requirements of the coating.
Mr. Shen from Jiangsu Province, is the owner of an electroplating factory engaged in acid galvanizing processing of various hardware parts. Recently, in the production process of using black zinc passivator, Mr. Shen found that the corrosion resistance of the black zinc workpiece after sealing is very poor, the workpiece is basically white rust after 24 hours of salt spray test, and the sealing film is easy to fall off, the customer can not accept such a workpiece. However, Mr. Shen extended the drying time of the workpiece, but there was still no improvement. The above Mr. Shen wants to search the Internet to see how this situation should be solved.
