Composting provides a way not only of reducing the amount of waste that needs to be disposed of, but also of converting it into a product that is useful for gardening, landscaping, or house plants.
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.
Pickling and Passivation Stainless steel can corrode in service if there is contamination of the surface. Both pickling and passivation are chemical treatments applied to the surface of stainless steel to remove contaminants and assist the formation of a continuous chromium-oxide, passive film.
