摘　　要：利用鼓泡法研究了甘氨酸二甲叉磷酸ＧＤＭＰ（Ｇｌｙｃｉｎｅｄｉｍｅｔｈｙ－ｌｅｎｅｐｈｏｓｐｈｏｎｉｃａｃｉｄ）在模拟冷却水中对ＣａＣＯ３垢的抑制作用，结果发现ＧＤＭＰ具有溶限效应，能有效的抑制ＣａＣＯ３垢的析出；通过对比实验还发现，其阻垢性能优于氨基三甲叉磷酸ＡＴＭＰ（Ａｍｉｎｏ－ｔｒｉｍｅｔｈｙｌｅｎｅｐｈｏｓｐｈｏｎｉｃａｃｉｄ），是一种性能优异的阻垢剂。The scale-inhibition of GDMP(Glycine dimethylenephosphonic acid) to calcium carbonate was studied by bubble method in this paper. Results show that GDMP can control CaCO3 scale to separate out from water effectively and it has threshold effect. By comparison with ATMP (Amino -trimethylenephosphonic acid), we found that the scale - inhibition of GDMP is better than ATMP, so we can say that GDMP is a kind of effective scale inhibitor to CaCO3 scale.
