Q. I want to know the uses and composition of Pickling Inhibitor used in the pre-galvanising process of cold rolled steel. A. Hello, Ishaq. Hydrochloric acid is used to remove rust and scale from steel. But hydrochloric acid will also attack and dissolve the steel itself. Pickling inhibitors are interfacially active compounds which bind to the steel as monomolecular layers, and shield it, reducing the attack on the steel.
Alum can cause stomach problems although it was once used in the pickling process to make pickles crisper. Alum is used in the canning process, particularly for pickles, to provide extra crunch. It is allowed by government agency, but its use is not recommended.
