In the production process of using chromium plating additives, the plating solution is more sensitive to impurities. When the impurity content is high, it will affect the brightness of the coating and the performance quality of the coating.So what are the impurities that affect the plating solution?
In the process of using nickel plating additives, the sections of some workpieces are layered and discontinuous.Some of these delaminations are between the nickel plating layer and the substrate, and some are between the nickel layer and the nickel layer. How are these delaminations formed?
We will find the presence of sodium carbonate in the bath after using the alkaline zinc-nickel alloy additive for a period of time.So where do these sodium carbonates come from?
When we use nickel plating brightener to produce, sometimes the coating of the workpiece will have gray-black or black stripes, which will seriously affect the appearance of the product.So how should the workpiece be dealt with when this phenomenon occurs?
In the production process of using nickel plating additives, we sometimes find that the nickel plating solution contains zinc ions, which leads to the phenomenon of black stripes on the nickel plating layer of the workpiece.So where do the zinc ions in the plating solution come from?
We use high-sulfur nickel additives to obtain nickel coatings with a sulfur content of 0.12% to 0.25%.It is mainly used for the protection of steel and zinc alloy substrates and the intermediate layer of decorative coatings, which can effectively improve the corrosion resistance of coatings.So when we use high-sulfur nickel additives, how should the bath be maintained?
