CORROSION INHIBITION OF MILD STEEL BY LOW MOLECULAR WEIGHT ANIONIC POLYELECTROLYTES

摘要

ABSTRACT OF THE DISCLOSUREA method of passivating the surface of and inhibitingcorrosion of mild steel in contact with low TDS industrial watershaving low calcium and low bicarbonate concentrations whichcomprises treating said low TDS waters with at least 10 ppm and,preferably, at least 25 ppm of a low molecular weight poly-carboxylic acid polymer having a molecular weight between 500 -50,000.
