  • The invention technology is used to put zinc block into the plating aid pool regularly, so that the bivalent iron in the plating aid becomes trivalent iron, and plays an important measure to stabilize the PH value within a numerical range, and also facilitate the filter filter out the trivalent iron ions in the plating aid; Ferric ion is controlled between 0.3 and 1.0g/L; When hydrogen is not released in the plating aid, the zinc block is continued. It is an effective measure to reduce zinc slag, improve the fluidity of zinc liquid and reduce the thickness of zinc layer to play the role of plating aid filter.

  • 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.
