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.
Why is the coating binding force still poor after plastic coarsening? In fact, this is related to the state of the plastic matrix. In this issue, we will discuss what is the meaning of the poor state of the plastic matrix? And how it causes poor coating adhesion in plastic electroplating process.
In the plastic plating process, the appearance of pinholes and pockmarks of the product often need to rework processing, increasing the production time and cost. If the defects are serious, the product may even be scrapped, resulting in a waste of resources. There are four triggers, this issue of the article we first analyze one of them, which is the electroless copper plating solution precipitation state is not good.
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.
Some customers said that they used alkaline galvanized production process, after the use of colored zinc passivator, they found that the workpiece will appear very serious discoloration phenomenon, resulting in the need to return the workpiece for rework, which caused great economic losses. So, what causes the coating of the workpiece to discolor?
To achieve a bluer trivalent chromium blue zinc passivate film color, some parameters in the passivation process need to be carefully adjusted. The following are some of the factors that may affect the color of the passivate film:
