We use decorative chrome additives to formulate the tank solution after the film, the better chrome plating solution should have 7~8cm bright range of plating, no burnt ash in the high end, and no yellow film or color film in the low area. But in the actual production, there are always some failures, what are the causes of such failures? And how to adjust?
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 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.
Lead ion impurities in the plating solution are not very common during the application of alkaline galvanizing additives, but they have a significant impact on the plating solution.
We need to follow these two principles in order to quickly troubleshoot and solve problems when flaking with hard chrome additives.
