改性腐植酸-膦基丙烯酸阻垢缓蚀剂的制备及性能研究

Preparation of QHA/ZPS as scale-corrosion inhibitors and their performance

采用溶液共混技术,制备了季铵化腐植酸(QHA)和膦基丙烯酸/马来酸酐共聚物(ZPS)的共混物(QHA/ZPS),与QHA和ZPS对比分析表明,QHA/ZPS共混物具有更好的阻垢、缓蚀能力,有良好的灭藻作用。当QHA/ZPS质量比为2～3∶1时,共混物的阻垢作用表现出明显的协同效应。其综合性能决定了QHA/ZPS是一种很有发展前景的多功能水处理剂。

The blends (QHA/ZPS) of quaternary humic acid (QHA) and copolymer of phosphonocontaining acrylic acid/maleic anhydride (ZPS) were prepared by solution blend.Their inhibition performance of scale and corrosion and properties of biocide were studied and compared with QHA and ZPS.Experimental results show that the blends (QHA/ZPS) have scale and corrosion inbibition performance,and biocide capability is good.When the mass ratio of QHA to ZPS is (2～3)∶1,the blends have synergic effects on scale inhibition performance.The excellent performance of QHA/ZPS determines that it is a valuable multipurpose watertreating agent.
