Zinc alloy die casting is easy to blister, which is a problem for many electroplating factories, because it is related to the straight-through rate of electroplating products, and will affect whether die-casting factory customers will continue to choose them. Therefore, it is very urgent to solve this problem. In this article, we will analyze the importance of pre-treatment wax and oil removal process for improving the binding force of zinc alloy coating.
Parts degreasing is an important process of plating pretreatment, plating parts degreasing quality is good or bad, will directly affect the quality of plating layer. For example, in the previous article, I have mentioned the nickel plating process, degreasing is not complete, it will cause the plating layer pinhole appearance. Therefore, it is very important to do a good job of degreasing. And when we choose alloy electrode degreasing powder, phosphorus-free is a very important index.
In the electroplating process, removing wax is an easily overlooked but important production process. In this article, we will introduce the definition of dewaxing water and the role of Bigely dewaxing water in the electroplating production process.
Some customers asked that in the production process of using zinc-nickel alloy colored passivator, the passivation film of the workpiece appeared black phenomenon, what is the cause of this?
With the continuous development of science and technology, the electroplating industry is also improving and innovating. Bigely electroplating zinc-nickel alloy blue passivator is an important raw material in the electroplating process, which has become a new favorite in the electroplating industry with its good performance and ideal anti-corrosion effect. So, how exactly does Bigely electroplating zinc-nickel alloy blue passivator help to improve the corrosion resistance of electroplated products? This article will analyze the following aspects.
As we all know, in the production process of plastic plating, the colloidal palladium adsorbed on the surface of the plastic workpiece after palladium activation does not have catalytic activity, which is due to its surroundings are wrapped by divalent tin ions, the use of peptizer can dissolve the palladium around the divalent tin so that it is exposed to deal with, so that palladium ions will have catalytic activity. So what do we need to pay attention to when we use the peptizer?
