After the surface of the chain link fence is cleaned up, it should be dipped galvanized according to the different requirements of the substrate material and coating to obtain a good coating.

Recipe introduction:

How to deal with chain link fence before electroplating?

Composition and process conditions

Sodium hydroxide 80~120g/L Additives appropriate

Zinc sulphate 30~40g/L, time, secondary zinc dip 20~30s

Nickel sulfate 30~40g/L temperature 20~30℃

Potassium sodium tartrate 80~100g/L

Composition of zinc dipping additives for chain link fence

Three kinds of surface potentials, sodium dodecyl sulfate, sodium dodecylbenzene sulfonate, and betaine, were selected through the experiment of chain link fence. The surface active agent is adsorbed on the surface of the chain link fence to make the zinc immersion solution spread more easily on the surface of the substrate. The stabilizer in the zinc immersion solution is generally Cu+ complexing agent, which can generate Cu-S and Cu-N chemicals with it, which can stabilize the zinc immersion solution.
