A NEW COMPLEX SCALE AND CORROSION INHIBITOR AND ITS INDUSTRIAL APPLICATION

A new kind of complex scale and corrosion inhibitor, which is used in cooling water in industries, has been exploited via orthogonal experiment. The corrosion inhibiting rate of the inhibitor reached 82.56%. The results of static inhibiting scale and corrosion evaluation tests show that the complex scale and corrosion inhibitor had satisfactory efficiency in corrosion and scale inhibition. When the concentration of the inhibitor was 50 mg/L, the corrosion and scale inhibiting rates of the inhibitor reached above 90%. In field application, it also had satisfactory efficiency.
