Experimental Study on a Green Phosphate-free Corrosion and Scale Inhibitor
Abstract：A new phosphate-free corrosion and scale inhibitor is made from chitosan (CTS), polyaspar- tic acid(PASP), additives A and zinc salt. Compared with the traditional corrosion and scale inhibitors, the corrosion rate increased by 2.08%, the scale inhibition rate increased by 1.62%, and its cost was re- duced by 6.7 %. Besides, this phosphate-free corrosion and scale inhibitors won't cause eutrophication. In terms of economic costs, product performance and environmental consideration, the new phosphate-free corrosion and scale inhibitor is significantly superior to the traditional one, boasting obvious economic and environmental benefits.
