When using copper pyrophosphate brighteners, various insoluble or undissolved solid particles in the plating solution are called mechanical impurities. When it settles on the surface of the workpiece and is enclosed in the plating layer, the plating layer is obviously rough.
When using decorative chrome additives, in order to ensure the quality of the plated layer, the plating plant should use a low ripple DC output power supply. However, in actual production, plating failures can also occur if not operated properly.
Plating plant in the use of alkaline copper brightener, the tank solution has impurities should be how to deal with? In this issue, we will analyze the article.
When using alloy chemical degreasing powder, why the degreasing effect is always unsatisfactory? On the one hand, it has something to do with the quality of degreasing powder, on the other hand, it may have something to do with the lack of ultrasonic cleaning. So why ultrasonic degreasing can make the degreasing effect become better?
What are the advantages of the cyanide-free galvanizing process? Let's analyze it today.
Hard chrome additive application process, due to the hexavalent chromium layer is easy to passivate (trivalent chromium chromium plating layer in trivalent chromium chromium plating solution passivation is poor; metal chromium passivation coefficient as high as 0.74, second only to aluminum and titanium), therefore, plating is not allowed to be a very short time in the middle of the power outage (the requirements of the workpiece and the hanging device should be elastic contact, the hanging device and the cathode copper rod to ensure that the conductive is good).
