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 is the process of preserving or expanding the lifespan of food by either anaerobic fermentation in brine or immersion in vinegar. The resulting food is called a pickle, or to prevent ambiguity, prefaced with the adjective pickled.The pickling procedure will typically affect the food's texture and flavor.In East Asia, vinaigrette (vegetable oil and vinegar) is used as the pickling medium. Another distinguishing characteristic is a pH 4.6 or lower, which is sufficient to kill most bacteria.Pickling can preserve perishable foods for months.atural fermentation at room temperature, by lactic acid bacteria, produces the required acidity. Other pickles are made by placing vegetables in vinegar. Unlike the canning process, pickling (which includes fermentation) does not require that the food be completely sterile before it is sealed.
