After using potassium chloride galvanizing additives for production, the electroplating plant needs to do black zinc passivation, but do you know all the production considerations? If you want to get a good quality passivation coating, you need to master the following eight matters.
Over the past decades, plating on plastics has gradually become an important process in many industries, such as electronics, automotive and home appliances, and has also had a profound impact on the environment and the economy. In this article we come to Bigely to introduce two advantages of the alkaline electroless nickel plating process in the production of plastics plating:
In the electroless nickel plating process, the use cycle of the plating solution is a crucial parameter, which not only affects the quality of the plated layer, but also directly relates to the speed of plating. Therefore, it is necessary to know what problems will be caused if the MTO of electroless nickel plating solution is too short? Especially what is its effect on the plating speed?
I am Mr. Li, the head of a manufacturer focusing on nickel plating of copper and aluminum parts. However, the workpieces after plating often have problems of peeling and bad bonding, which makes me very distressed. These problems not only affect the appearance quality of the products, but also make our customers lose confidence in our products. I heard that the use of electroless nickel plating process can solve the problem, but this is something I am not familiar with, and I need to seek the guidance of the additive supplier.
In the production process of trivalent chromium color passivation, the gloss of the passivation film is one of the important indicators of its quality. However, the problem of poor passivate film gloss is often encountered in practice. This phenomenon involves a variety of factors, including the composition of the trivalent chromium colored zinc passivator, the quality of the plating layer, and the control of the passivation process.
In the current condition of high environmental protection requirements, traditional Cr(VI) passivators are gradually being eliminated from the market due to their toxicity and pollution.
