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.
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.
In the electroplating industry, the dispersing ability of the plating solution is a key factor that affects the uniformity and quality of the plated layer on the substrate. Additives in the nickel sulfamate plating process play a vital role in regulating this property.
In recent years, with the rapid development of new energy vehicles, electroplating technology plays a key role in ensuring the performance of auto parts and reducing manufacturing costs. Zinc-nickel alloy plating process has become a popular choice in the new energy vehicle industry due to its good corrosion resistance and mechanical strength. Among them, Bigely BZ-617 alkaline zinc-nickel alloy brightener has attracted much attention because of its own properties.
When you are doing the production of electroless nickel plating, you must face a big problem: poor stability of the plating solution, slow deposition, resulting in low productivity and high production costs. What should be done?
