Abstract

Properties and mechanism of a non-phosphorus inhibitor were studied, in the simulate condition of a circulation cooling system. The inhibitor enable control the corrosion of system containing both carbon steel and copper alloy, which is similar to a real circulation cooling system. Studies showed that the inhibitor showed excellently corrosion inhibition properties and protect metals well. Scale inhibition experiment showed that the rate of scale inhibition could reach up to 98%. Therefore, the environment-friendly inhibitor is an efficiency inhibitor and could control both corrosion and scaling for the circulation cooling conditions.
