In the production process of using electroless nickel plating solution, sometimes the electroless nickel coating of the workpiece will be rough, which will affect the appearance and performance of the coating.And the roughness of the electroless nickel plating layer is the improper addition of the electroless nickel plating solution used?
In the production process of using high-phosphorus electroless nickel plating solution, sometimes the plating solution will be poisoned.That is, the amount of hydrogen evolution on the workpiece is less than that under normal conditions, the deposition rate is very slow, and some workpieces stop deposition after entering the plating solution for a few minutes.How can the plating solution be poisoned?
In the production process of using galvanized trivalent chromium black passivator, sometimes the color of the workpiece is slow during passivation, which affects the efficiency of production.So what is the reason for the slow coloring when the workpiece is passivated?
In the production process of alkaline galvanizing, sometimes the brightness of the coating of the workpiece is not enough, we will add more alkaline galvanizing brightener to improve the brightness of the galvanizing layer.And sometimes the coating is not bright, even if the brightener is added, the brightness of the coating is not improved, why is this?
In the production process of using medium-phosphorus electroless nickel plating solution, sometimes a layer of electroless nickel plating is easily deposited on the tank wall and tank bottom of the plating tank, which will affect the product quality and the service life of the plating solution.So, how should we avoid depositing electroless nickel coating on the tank wall and tank bottom during the production process?
In the production process of using galvanized trivalent chromium black passivator, sometimes the coloring of galvanized workpieces is slow during passivation, which affects the efficiency of production.What is the reason for this phenomenon?
