Many customers choose cheaper colloidal palladium activators in the production process of plastic electroplating. Little did they know that cheap activators not only have low concentration, poor activity, large dosage, but also high production costs. So, choosing high concentration colloidal palladium activators can save production costs!
A customer inquired that the blue white passivation of their own alkaline zinc workpieces is always prone to yellowing, but the passivation solution has been adjusted several times without solving this problem.
We all know that oily acidic zinc plating brighteners have high COD values due to the presence of surfactants or additives, making wastewater treatment more difficult.
We all know that in the production process of using acid copper brighteners, the presence of monovalent copper in the plating solution will affect the brightness of the coating and reduce the quality of the acid copper coating. So what should we do with the monovalent copper in the plating solution?
A customer has reported that during the production process using chemical nickel plating additives, the porosity of the workpiece coating is large and the corrosion resistance is poor. What is the reason for this phenomenon?
We all know that sulfuric acid hydrochloric acid based tin plating brighteners have been widely used due to their high current efficiency, fast deposition speed, low electroplating cost, and easy treatment of wastewater.
