What are the effects of metallic impurities, such as iron and copper ions, on the quality of the plated layer during the production process using acid tin plating brighteners?
When using potassium chloride galvanizing brightener, the product is burnt now, how to deal with it? Recently we saw this inquiry, so we decided to write an article to do the answer.
In the field of metal surface treatment, the technology of methanesulfonate tin plating is favored because of its environmental friendliness and the stability of the plating solution. While conventional tin plating processes often use strong acid or cyanide systems, the methanesulfonate system is not only environmentally friendly, but also capable of obtaining uniform plating over a wide range of current densities. However, the performance of the plating solution itself is not perfect, and it is then necessary to rely on the use of continuous bright tin plating additives to enhance it.
In the electroplating industry, the surface treatment of high carbon steel substrates has always been a technical difficulty. Although the traditional hydrochloric acid activation method can improve the activity of the substrate to a certain extent, it often leads to gray hanging on the surface, which in turn affects the quality and adhesion of the plating layer. This not only affects the aesthetics of the product, but may also lead to a decline in the performance of the product during use. In response to this problem, Bigely Technology has introduced acid salt activator BC-629.
The development of the high-phosphorus electroless nickel plating market is gradually growing, and the technology has been widely used in automotive, aerospace, electronics, metallurgy and machinery. In the continuous development of high-phosphorus electroless nickel plating technology, the focus of research is beginning to develop towards the use of new additives, improve the stability of the plating solution and other directions, in order to improve the application of the technology in a wider range of fields.
Some customers inquired about what problems would be caused by a too high pH value when using a copper pyrophosphate brightener.
