缓蚀阻垢剂的筛选及工业应用

针对现场循环冷却水的水质情况，研究了一种适用于循环冷却水的缓蚀阻垢剂配方，通过正交试验筛选出了一组最佳的浓度，使用该配方的缓蚀率达到82．56％。经静态阻垢试验和缓蚀评定试验分析，结果表明该配方有良好的缓蚀阻垢性能。当药剂配方浓度达50mg／L时，其缓蚀率和阻垢率均达到90％以上。在现场循环冷却水系统的应用中，对改善循环水水质也有很好的效果。

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.
