Post-plating treatment of hot-dip galvanized wire for enhanced protection function, decoration and other special purposes (passivation, hot melting, closing and hydrogen removal, etc.). After galvanized, chromate passivation or other conversion treatment is generally required, forming the corresponding type of conversion film is one of the key processes to ensure the quality of plating. Because hot-dip galvanized wire has a long anti-corrosion life, a wide range of applications, hot-dip galvanized wire to net, rope, wire and other ways are widely used in heavy industry, light industry, agriculture, widely used in the manufacture of wire mesh, highway guardrail and construction engineering and other fields.

The management system of the rinsing water after the steel wire pickling should be regularly and regularly discharged after the rinsing water, and the rinsing water should be kept clean and low acid value as far as possible. The pH control is more appropriate. The concentration of plating aid should not be too high. Hot plating wire must be added ammonium chloride and zinc chloride according to the data of laboratory analysis, and the specific gravity of the composite solution is controlled in the range of 50~80g/L. The addition of ammonium chloride or zinc chloride raw materials without the results of laboratory analysis shall be subject to criticism and education, and economic treatment if necessary.
