  • Removal of surface-active substances by activated carbon matting. Or make the bubble unstable according to overworry, these are all reasonable countermeasures; Other strategies should also be used to minimize the amount of surfactant taken in. The introduction of organic matter can make the electroplating process speed drop sharply. Galvanized iron wire blackening can be effectively prevented, such as: the work site to keep dry, reduce and do not use chemicals, operators with clean gloves and so on. In addition, hot dipping zinc factory can be required, after dipping zinc must be passivation treatment, passivation treatment of zinc has a better anti-discoloration effect, can effectively prolong the discoloration time, the combination of the two, discoloration should be able to solve.

  • Hot dip galvanizing is then oiled and chromed. The quality of hot-galvanized sheet produced by this method is significantly improved compared with that by wet galvanizing method. It is only valuable for small-scale production. Continuous galvanizing production line includes a series of pretreatment procedures, such as alkali degreasing, hydrochloric acid pickling, water washing, solvent coating, drying, etc., and the original plate needs to be annealed in cover furnace before entering the galvanizing line.

  • Therefore, when the zinc reaches saturation in the solid melt, the two elements of zinc and iron atoms are diffused with each other, and the zinc atoms diffused into (or infiltrated into) the iron matrix migrate in the lattice of the matrix and gradually form an alloy with the iron, while the iron diffused into the molten zinc liquid forms an intermetallic compound FeZn13 with the zinc and sinks into the bottom of the hot galvanized pot, that is, zinc slag. When the workpiece is removed from the zinc leaching solution, the surface of the pure zinc layer is formed, which is hexagonal crystal, and its iron content is not more than 0.003%.

  • The derusting steel parts are immersed in the melted zinc liquid at about 500℃, so that the surface of the steel member is attached with zinc layer, so as to achieve the purpose of anti-corrosion. The surface of galvanized wire coating can see whether the quality of galvanized wire is good or not. If the strength of zinc attached to the wire is very poor, then this galvanized wire do not buy, because this galvanized wire must be poor galvanized wire.
