摘要

It has been found that polymers lightweight CONTAINING MOLECULAR are a hydroxamic acid CORROSION INHIBITORS EXCELLENT FOR IRON AND STEEL ALLOYS CONTACT INDUSTRIAL WATERS. WHEN THE WATERS CONTAIN hardness ions such as calcium, magnesium and mixtures thereof, WATER TREATED PREFERABLY WITH COMBINATIONS polymers containing hydroxamic acid and polymers INHIBITORS / dispersant SCALE, WHOSE POLYMERS NOT CONTAINING FUNCTIONAL GROUPS hydroxamic acid. Polymers containing hydroxamic acid and the polymer blend YE hydroxamic acid inhibitors / dispersing SCALE CAN formulated with other corrosion inhibitors.
