When we use alkaline galvanizing additives for barrel plating production, sometimes the coating of the workpiece will have obvious burrs, which will affect the appearance of the workpiece.So where do the burrs of the galvanized layer come from?
In the production process of nickel plating, sometimes the nickel plating layer of the workpiece is easy to burn, which affects the appearance and performance of the workpiece.The unqualified coating quality of the workpiece will affect the progress of production.Is this an improper use of nickel plating additives?
After we use the trivalent chromium color zinc passivator normally, the galvanized workpiece can obtain a uniform and bright color film layer.But sometimes the color of the hole position after color passivation of the galvanized workpiece will be darker, showing a yellow-green color.Is this the improper operation of trivalent chromium color zinc passivator?
When we use the trivalent chromium blue zinc passivation solution, the galvanized workpiece can obtain a good bright blue appearance.However, sometimes yellow spots appear on the appearance of the workpiece after passivation, which seriously affects the appearance quality of the workpiece.Is this caused by improper use of trivalent chromium blue zinc passivation solution?
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?
