In order to be able to solve the shortcomings of electrogalvanized iron wire direct selling in alluvial surface to partially remove the surface film layer, surface interference and other defects can be found according to the basic technology; Excessive lather is caused by soaps and soaps of surfactants such as human fat brought into the tank. A moderate rate of bubble formation would be harmless. The fine homogeneous particles of large denser in the tank can stabilize the foam layer, but the accumulation of too many solid particles will cause explosion.
Activated carbon mat was used to remove surfactants. Or make the bubble not too smooth according to overthinking, these are all reasonable countermeasures; Other measures should also be adopted to minimize the amount of surfactant introduced. The introduction of organic matter can make electroplating process speed down sharply.
Galvanized iron wire blackening can be effectively prevented, such as: keep the workplace dry, reduce and do not use chemical substances, operators with clean gloves, etc. In addition, hot dip zinc factory can be required, zinc must be passivated after dipping, passivated zinc has better anti-discoloration effect, can effectively prolong the time of discoloration, the combination of the two, discoloration should be able to solve. Galvanized iron wire has good toughness and elasticity, zinc content can reach 300 grams/square meter. It has the characteristics of thick galvanized layer and strong corrosion resistance.
