In the electroplating industry, trivalent chromium blue-white passivates are widely used to enhance the corrosion resistance and aesthetics of zinc and its alloy surfaces. The color of the passivation film not only affects the appearance of the final product, but also indirectly reflects the quality of the film. Below are a few key factors that affect the color of trivalent chromium blue-white passivate films.
What factors are related to the protective properties of the plated layer when we use acid zinc brighteners? According to Bigely many years of experience in electroplating technical service, it is related to the following two points.
Alkaline cyanide-free galvanizing process requires the use of a variety of additives in the production process, the common alkaline cyanide-free galvanizing additives are brightener, carrier brightener, auxiliary brightener, wetting agent and degaussing agent, etc., which can work at the same time, but also can work separately.
When selecting the right matte tin additive, considering the performance of the plating layer and the performance of the plating solution are two key factors. In this article, we will introduce how to matte fogging tin additives.
Metal impurities in the tin plating solution such as copper ions and iron ions can interfere with the tin plating process. These impurity metals can be co-deposited during the plating process, resulting in an impure composition of the plated layer, which in turn affects the physical and chemical properties of the plated layer. Therefore, it is necessary to know how to remove impurities from tin plating solution.
The decorative chrome plating process is widely used in automobiles, home appliances and consumer electronics because it not only provides a beautiful appearance, but also good corrosion resistance. However, in practical applications, problems such as poor plating alignment and insufficient plating in low areas often plague plating workers. In this article, we will introduce Bigely decorative chrome plating additive Cr-8 and discuss how it solves the problem of plating alignment.
