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?
We all know that the trivalent chromium blue zinc passivation workpiece needs to have a good bright blue appearance, but sometimes the appearance of the workpiece will appear yellow spots after passivation, which seriously affects the appearance quality of the workpiece.Is this yellow spot caused by improper use of trivalent chromium blue zinc passivation solution?
The trivalent chromium color zinc passivation workpieces we normally produce are uniform and bright color films, and sometimes the color of the passivated holes in the workpieces will be darker, showing yellowish green.Is this the improper operation of trivalent chromium color zinc passivator?
