PMAH-AM-MA的阻垢缓蚀性能及其应用

The Characteristic and Application of the Scale-Corrosion Inhibition of PMAH-AM-MA

评定了PMAH-AM-MA水质稳定剂的阻垢、缓蚀性能.其阻碳酸钙垢、磷酸钙垢及硫酸钙垢的效果分别为96.7％,95.8％和97.2％;缓蚀率为83.9％.探讨了PMAH-AM-MA的阻垢缓蚀机理.并将它应用于甘肃白银稀土公司烧碱厂的循环冷却水,现场测得其阻垢(主要指钙垢)效果为90.2％.试验结果表明了PMAH-AM-MA水质稳定剂具有优异的阻垢、缓蚀性能和广泛的工业应用前景.

The scale-corrosion inhibiting performances of PMAH-AM-MA water stabilizer are evaluated. Inhibiting scale ratios of PMAH-AM-MA to CaCO3,Ca3(PO4)2 and CaSO4 are 96. 7% ,95. 8% and 97. 2% and inhibiting corrosion ratio is 83.9%. The mechanism of it has been discussed. PMAH-AM-MA has been applied to the circulating cooling water of Caustic Soda Factory of Gansu Baiyin Rare Earth Company. And inhibiting scale ratio of it to calcium scale is 90.2%. The results indicate that PMAH-AM-MA has excellent scale and corrosion inhibition efficiency, and broad prospect in industrial application.
