  • Deion of additives for plating aid
    The additive is composed of low surface tension active agent, cleaning agent of silicon, sulfur, phosphorus and other raw materials on the surface of l, dehydrating agent of work piece, iron ion complexing agent and so on. The cleaning effect on the steel surface is removed, and the iron salt or oxide remaining on the surface of the workpiece after pickling is removed, so that the iron and steel parts have more surface activity when they enter the zinc bath. Extend the time of rust return from the plating pool to the zinc pot in the air.
