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, the production cost and the environmental protection cost, in order to help plating factories to choose the suitable passivation process.
In zinc-nickel alloy plating and passivation treatment, yellowing phenomenon often occurs at the corners and holes, which seriously affects the overall aesthetic and protective performance. In this regard, the application of Bigely Zn-323 zinc-nickel alloy trivalent chromium blue zinc passivator effectively solves these problems. Today's article will help you analyze the advantages of Zn-323 and its merits in practical applications.
After we perform palladium activation in the plastic plating process, we also need to perform accelerating. What is the main function of the accelerating? What kind of electroplating accelerator do we need to choose? Let's discuss these two questions in this article.
Electroless nickel plating is widely used in various industrial fields, but pinholes often occur when the thickness of the plated layer is large, thus affecting the bonding and overall quality of the plated layer. In this issue, we will introduce how nickel plating wetting agent can improve the quality of electroless nickel plating layer and avoid the problem of pinhole plating.
A good potassium chloride galvanizing brightener is not only reflected in the bright uniform appearance, but also has a superior performance, and through the performance test can understand the brightener is good or bad. Take BZ-528 potassium chloride galvanizing brightener of Bigely Technology as an example for performance test:
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?
