| 摘 要： | 本文采用聚氧丙烯二胺、三氯化磷和甲醛为原料合成了一种大分子有机膦酸-聚氧丙烯二胺四亚甲基膦酸（PDAMP），并对其结构进行了表征。采用鼓泡法测试其阻碳酸钙垢行为，结果表明：在10mg／L以下时其阻垢性能较差，但在20mg／L时PDAMP表现出很好的阻垢性能，阻垢率达到60％以上，并且具有良好的析晶延迟作用；PDAMP的阻垢行为与单分子有机膦酸不同，而与聚合物PAA相似。

| Abstract: | A new phosphonic acid,polyoxypropylenediaminetetramethylene phosphonic acid(PDAMP),was synthesized,and the structure was identified with FT-IR and 31P-NMR.Bubbling method was used to test scale inhibition behavior of PDAMP,and it was found that: 1) the ability of scaling inhibition was poor when the dosage was less than 10mg/L.But it was very good at 20mg/L with scale inhibition rate of over 60%,moreover,the crystal-delaying behavior was observed;2) scale inhibition behavior of PDAMP is similar to PAA-a polyelecrolyte inhibitor. |
