Stripping in galvanizing a regenerative process
Within the manufacturing course of action we find the stripping phase. The galvanizing process is where small inaccuracies may occur. The step where galvanized layers not in compliance with the standards are removed from the artifact to allow the new entry into the production line is called stripping.
We might define stripping as a “degalvanization” procedure, also used as a periodical facility maintenance in order to clean them up and submit them again to a galvanizing process. The generally used area for stripping is usually outside the galvanizing process and nonetheless not adjacent to the pickling plant.
The tanks used for the stripping are placed within an acids-resistant containment basin. Its materials in this stage are immersed in a hydrochloridric acid and water solution at room temperature. Its duration varies depending on the thickness of the artifacts’ spelter coating.
From the stripping bath, once exhausted, it is possible to retrieve the zinc-chloride residue (there are specialized companies for carrying out this task), avoiding expensive disposal costs and reducing the overall treatment’s carbon footprint.
