Often the problem with iron wire galvanized coating roughness, blisters on the coating, slow deposition rate.
1 rough coatings, passivation film does not shine. Bath temperature is too high; the cathode current density is too large, plating zinc content is too high or sodium hydroxide and DPE content in liquid is too low; the plating solution with solid particles or different metal impurities such as too much will cause this type of failure.
Blister 2 coating, bonding force. Before plating processing not good; bath temperature is too low; additive quality is not good or additives and organic impurities, too much will cause the binding force is not good.
3 slow deposition rate, deep plating ability difference. Low bath temperature; cathodic current density is small; the plating solution of sodium hydroxide content or DPE content is too low, turbid bath or lead different metal impurities will appear this kind of problem.
