In the electroplating industry, alkaline galvanizing brighteners are widely used, and they can effectively improve the gloss and overall appearance quality of the plated layer. However, the presence of excessive iron impurities in the plating solution can have a significant impact on the plating process. In this article, we will discuss in detail the effects of excessive iron impurities in the plating bath when using alkaline galvanizing brighteners and mention why using Bigely alkaline galvanizing brightener, BZ-518, is a wise choice.

The presence of iron impurities in the plating solution will adversely affect the galvanized layer. When the iron content in the plating solution exceeds a certain limit, such as reaching more than 50mg/L, the surface of the galvanized layer is prone to darkening and blackening, or even black streaks. This is due to iron impurities in the electroplating process and zinc ion competition, affecting the normal deposition of zinc, resulting in uneven coating structure, corrosion resistance decreased. In addition, iron impurities may also trigger an increase in the brittleness of the plating layer, reducing the service life of the product.

Advantages of using Bigely alkaline galvanizing brightener BZ-518

Bigely alkaline galvanizing brightener BZ-518 has good plating performance, and the addition of the de-adulterant BZ-518C can reduce the interference of iron impurities in the production. BZ-518 brightener not only has good dispersing ability and deep-depositing ability, which ensures even and bright plating, but also has a good stability of plating solution and a long service life.
