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 plastic plating accelerator 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 plastic plating accelerator?
Electroplated colored zinc passivation process is vital in the corrosion protection of steel and metal products. The passivation process is mainly divided into two types: trivalent chromium passivation and hexavalent chromium passivation, and each of these two technologies has its own advantages and disadvantages. In this article, a detailed comparison of trivalent chromium and hexavalent chromium passivation will be made in terms of the performance of the passivated film layer, production costs and environmental costs, in order to help plating factories to choose the appropriate passivation process!
BZ-216 trivalent chromium black zinc water is a single-dosage liquid concentrate, which is a trivalent chromium black zinc process suitable for zinc plating, suitable for rack plating and barrel plating, and can be used together with the corresponding coating, which can produce bright and uniform black passivation film on the galvanized layer.
The pH value of Bigely neutral tin plating process is nearly neutral, which is suitable for the plating of materials susceptible to acid, alkali influence or corrosion, such as special glass, ceramic materials as the substrate of the component solderable ends, leads. So, how should we maintain the plating solution in daily production?
Nickel electroplating is a common surface treatment process, widely used in the protection and decoration of various metal products. However, the nickel plating process often encounters the problem of plating peeling, which not only affects the appearance of the product, but also reduces its anti-corrosion properties. In order to have an in-depth understanding of this phenomenon, we will nickel plating peeling of the main reasons are summarized below:
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.
