Abstract:
plating agent--ammonium zinc chloride regeneration device Chengdu Siyou mechanical and electrical equipment company Zhang Zhu 0 overview in the hot-dip galvanizing production process, plating agent is a crucial catalyst, it plays an important role in the formation of a strong anti-corrosion zinc protective layer on the surface of the plated parts. The plating aid should have the following conditions: (1) dissolve the residual iron salt on the surface of the plated parts after acid washing; (2) prevent the surface of the plated parts after acid washing from re-oxidation; (3) can...
