Synergist Action of Some Inhibitors Mixtures for Anticorrosive Protection of Steel in Cooling Waters

摘要

It was studied the anticorrosive action of some inhibitors mixtures for steel protection in cooling waters. By X-rays analysis it was determined the composition of solid deposits formed in coolers. Inhibitor mixtures containing magnesium lignosulphonate, sodium tripolyphosphate and zinc sulphate present a synergist action in the process of corrosion inhibition for OLC 45 steel in cooling waters, obtaining increased efficiencies.
