To remove surface active substances by matting with activated carbon. Or filtration to make the foam less stable, which are effective measures; Other measures should also be taken to reduce the amount of surface-active substances brought in to Z. The electroplating speed can be significantly reduced by the introduction of organic matter. Although the chemical formula is conducive to a high deposition rate, the coating thickness cannot meet the requirements after the organic matter is loaded, so activated carbon can be used to treat the tank.

When the zinc layer is seriously damaged and endangers the iron matrix, the zinc will produce electrochemical protection on the matrix, the standard potential of zinc is -0.76V and the standard potential of iron is -0.44V. When zinc and iron form microbatteries, the zinc will be dissolved as the anode, and the iron will be protected as the cathode. Obviously, the atmospheric corrosion resistance of hot dip galvanizing is better than that of electric galvanizing.

Dip plastic six side barbed wire corrosion lost the original characteristics, in the shape, color and mechanical properties and other aspects will change, resulting in equipment damage, pipeline leakage, in particular, is prone to fracture, lose the original protective function.
