介绍了一种氨烷基膦酸型水处理剂二甲基氨基甲叉二膦酸(DMAMDP)的合成方法,并进行了缓蚀阻垢性能的研究。结果表明,DMAMDP在阻碳酸钙、硫酸钙、磷酸钙和稳定锌等方面,以及缓蚀性能均优于常用有机膦酸水处理剂HEDP和ATMP。
The method of synthesis on[(dimethyIamino)methylene]bisphosphonic acid was intnoduced.The performance of inhibiting scale and inhibiting corrosion of the synthetic product was studied and a contrast with two commonly used water treatment agents,HEDP and ATMP were carried out.The experimental result showed that the seale inhibition and the corrosion inbibition of DMAMDP were prior to HEDP and ATMP.
