耐高硬度、高碱度、高pH值阻垢分散剂的制备及性能研究

Preparation and Performance of Inhibition and Dispersion in High Hardness,High Scale,High pH Value Medium

以马来酸(酐)(MA),2 丙烯酰胺 2 甲基丙基磺酸(AMPS),2 丙烯酰胺 2 甲基丙基膦酸(AMPP)为单体,以水为溶剂,次磷酸钠 过氧化氢为引发系统,制成三元共聚物.对该共聚物的聚合条件、聚合性能和在高硬度、高碱度、高pH值水介质中的阻垢分散性能进行讨论和实验,结果表明,该共聚物有良好的综合性能.

A copolymer was prepared from malaic anhydride (MA), 2-acrylamido-2-methylpropane sulphonic acid (AMPS) and 2-acrylamido-2-emthylpropane phosphonic acid (AMPP). The ploymerzation was initiated by hypophosphite sodium and peroxide in aqueous solution. The performance was tested when copolymer polymerzated in different condition. It was also investigated that the copolymer's inhibition and dispersion performance in high hardness, high scale, high pH value medium. The results all showed that the copolymer is a good scale inhibiter.
