针对碳酸钙垢的控制，合成了一种新型环保型阻垢剂MLn。采用红外光谱、核磁共振氢谱、热重分析和凝胶渗透色谱等手段对ML15的结构和热性能进行了表征和测试。通过静态阻垢试验研究了MLn共聚物对CaCO3在人工冷却水中的阻垢性能，结果表明，随着MLn聚合度从5增加到15，对CaCO3的阻垢作用增强，MLn的投加量对CaCO3的阻垢效果有重要影响。结合扫描电镜（SEM）和X射线粉末衍射（XRD）分析研究了对碳酸钙形成的影响。提出了钙离子与聚乙二醇（PEG）之间的相互作用是抑制冷却水系统结垢的根本动力。
For the control of calcium carbonate scales, a novel environmentally friendly type of scale inhibitor MLn was synthesized. The structure and thermal property of ML15 were characterized and measured by FT-IR, H-1-NMR, TGA and GPC. The anti-scale property of the MLn copolymer towards CaCO3 in the artificial cooling water was studied through static scale inhibition tests, the observation shows that CaCO3 inhibition increase with increasing the degree of polymerization of MLn from 5 to 15, and the dosage of MLn plays an important role on CaCO3 inhibition. The effect on formation of CaCO3 was investigated with combination of scanning electronic microscopy (SEM) and X-ray powder diffraction (XRD) analysis. Inhibition mechanism is proposed that the interactions between calcium and polyethylene glycol (PEG) are the fundamental impetus to restrain the formation of the scale in cooling water systems.
