In the application process of zincate galvanizing additive, we always hope that the distribution of the thickness of the galvanized layer on the workpiece is as uniform as possible.And sometimes the thickness of the galvanized layer deposited on the workpiece is not uniform. What are the disadvantages?
The correct addition of alkaline zincate zinc plating additives can ensure that the product obtains a good coating. However, improper addition will adversely affect the quality of the coating. Therefore, how to correctly use and supplement additives directly affects the quality of alkaline zinc plating.
With the development of zinc plating technology, zinc plating chemicals are becoming more and more mature. The zinc electroplating chemicals on the market have little difference in function, dosage and use parameters, but the price is quite different. Why?
Some customers reported that the alkaline zinc-nickel alloy brightener being used is not easy to use, the plating solution is unstable, and the plating solution needs to be treated frequently; the workpiece has poor coating uniformity, brittleness
In the process of using alkaline zinc plating additives, sometimes the coating of the workpiece is prone to blistering and poor adhesion, which seriously affects the quality of the coating. What causes this?
Most of the rusty or thick surface parts are removed by mechanical methods such as sandblasting and shot blasting, but after mechanical rust removal, ensure that the surface of the workpiece is clean and free of scale.
