Materials of qualified quality should be kept marked for reference when used. In order to remove the surface film, surface inclusion and other defects on the surface of the large roll galvanized wire on the surface of the sedimentary layer to the local surface, it can be found and treated by conventional technology; Excess foam is caused by soaps and saponable fatty surfactants being brought into the tank. Moderate foam formation rates may be harmless. The presence of small homogeneous particles of large denier in the tank can stabilize the foam layer, but the accumulation of too many solid particles can cause explosion.

If the coating roughness is not caused by the above reasons, it may be caused by impurities in the plating solution. Can take a small amount of electroplating solution, filtration test, and then take a small amount of electroplating solution, with zinc powder treatment after the test, check the problem is solid particles or copper, lead and other foreign metal impurities caused by. One by one, it’s not hard to find the cause of the problem. Galvanized iron wire coating blister, poor adhesion.
