In the electroplating process, degreasing is of great importance as a key pretreatment process. However, many electroplating factories often have to face a troublesome problem when electrolytic degreasing: frequent smoke and irritating odor during operation. These phenomena not only bring health hazards to the operators, but also seriously affect the environmental quality of the workshop. In this article, we will discuss the causes and solutions of this problem in depth, and provide suitable improvement measures for electroplating plant owners.
Electroless nickel plating is an important surface treatment technology. Unlike conventional electroplating processes, electroless nickel plating does not require an applied electric current and forms a homogeneous, compact nickel-phosphorus alloy layer on the surface of the workpiece through a chemical reduction reaction. The properties of this coating can vary depending on the phosphorus content, thus playing a crucial role in different industrial applications.
In the electroless nickel plating process, the hardness of the plated layer is an important assessment index, which is related to the electroless nickel plating products can be sustainably applied in industrial production, so what are the methods of plating layer hardness testing? This issue of the article we will introduce two methods.
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.
