In galvanized，what is the role of pickling and washing?
The role of pickling is mainly as follows:
Firstly, it removes oxides, rust and other impurities on the surface of the wire rod to make the surface clean and prepare for the subsequent galvanizing treatment, so that the zinc layer can adhere better to the wire rod.
The role of washing is:
To wash away the acid solution and its reaction products remaining on the surface of the wire rod after pickling, to avoid these residual substances from having adverse effects on the subsequent process and product quality, and also to provide a clean surface condition for entering the next fluxing process.
