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, after filtration test, then take a small amount of electroplating solution, after zinc powder treatment test, check the problem is caused by solid particles or copper, lead and other foreign metal impurities. Test them one by one and it’s not hard to find the cause of the problem. Galvanized iron wire coating foaming, binding force is not good.

The impregnated hexagonal wire mesh will lose its original characteristics after corrosion, and will change in shape, color and mechanical properties, resulting in equipment damage, pipeline leakage, etc., specifically, it is easy to break and lose the original protection function. Usually there are three kinds of metal corrosion: physical corrosion, chemical corrosion, electrochemical corrosion, corrosion in addition to the chemical properties and organizational structure of the metal itself, but also related to the surrounding medium, such as wet environment than dry environment easy corrosion, more impurities than impurities less easy corrosion, high temperature conditions than low temperature conditions easy corrosion. After understanding these, we can effectively prevent the corrosion of impregnated hexagonal wire mesh, prolong the service life of products.
