When using galvanizing additives, uneven plating is the main problem that leads to the low pass rate of one-time galvanizing of products, so what harm will uneven plating cause? And how to solve it?
Some electroplating factories in the zinc plating after the delivery inspection found that the parts plating layer thickness is not uniform, the same parts in different locations at the plating thickness varies; in addition, the plating layer appearance is not uniform, after the installation of the long-term exposure to the air or wet environment, there will be a number of minor spots, pinholes or pockmarks, over time the defects will be gradually enlarged, which will affect the plating layer of the appearance and the performance of the use of the workpiece, especially the The functional properties of the workpiece will also be affected.
In addition, some electroplated zinc parts over-passivated, passivated surface discontinuity, un-passivated areas gradually corrode out of control later will also interfere with the use of the characteristics of the parts.
Therefore, in order to improve the uniformity of the plating layer, we need to use a good quality galvanizing additive, Bigely galvanizing additive BZ-518, after adding it to the bath, it can increase the degree of cathodic polarization, so that the current is uniformly distributed in the system, thus improving the dispersing ability of the bath, and obtaining the plating layer with detailed organizational structure and a very high degree of finish.
