  • Pure zinc is more stable in dry air. In moist air or water containing carbon dioxide and oxygen, the surface will generate a layer of basic zinc carbonate based thin film layer, which can delay the corrosion rate of zinc layer. Comparison of corrosion resistance of zinc coating in aqueous solution of acid, alkali and sodium chloride; It is also resistant to corrosion in atmospheres containing carbon dioxide and hydrogen sulfide and in oceanic atmospheres; In high temperature and high humidity air and contain organic acid atmosphere is small, galvanized layer is also easy to be corroded.

  • In order to remove defects such as surface film layer and surface inclusion of large roll galvanized wire, it can be treated by conventional technology. 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. Activated carbon mat to remove surface active substances, or through filtration to make the foam less stable, these are effective measures; Other measures should also be taken to minimize the intake of surface active substances. The electroplating speed can be significantly reduced by the introduction of organic matter.
