Some customers ask why the pre-treatment step of degreasing should be added before flash tinning of cold rolled steel plates? And how to choose the right steel electrolytic degreasing powder?
In recent years, with the application of aluminum alloy in industrial production, in order to improve the performance and appearance of aluminum alloy, people began to take the plating process, there are a lot of plating people think that the pretreatment process of aluminum alloy is the same as the plating of ordinary workpieces, not knowing that, due to the specificity of aluminum alloy substrate, if we take the same process as the ordinary plating pre-processing, then it will lead to the problem of the poor bonding of the plating layer with the substrate, so it is necessary to sort out the pretreatment process. Therefore, it is necessary to sort out the pre-treatment process. In this article, let's talk about how to use zinc sinking water.
The rust removal process of the phosphating pre-treatment of steel parts is actually the same meaning as the pickling of the electroplating pre-treatment of steel parts, which is to remove the oxide and rust on the surface of the substrate, but also to activate the substrate surface. So can you replace hydrochloric acid with an acid activator in this process?
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.
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.
Regarding the production of zinc alloy plating, why the plating layer will blister, we have summarized the following reasons and countermeasures:
