【摘要】 合成了一系列丙烯酸─丙烯酸甲酯─丙烯酰胺阻垢分散剂，研究了共聚物浓度、钙离子浓度、水质ｐＨ值、温度及恒温时间对阻垢性能的影响。研究结果表明：该阻垢分散剂对碳酸钙、硫酸钙、磷酸钙具有较优异的阻垢性能，且对循环水硬度、ｐＨ值及温度适用范围广，可广泛用作工业循环冷却水的阻垢分散剂。更多还原

【Abstract】 In this paper, a series of Acrylic acid-Methyl acrylate-Acrylamide copolymersfor antiscalants was synthesized. The effect of the copolymer concentration, the Ca2+concentration, the PH value, the temperature and the operating time on the antiscaleproperty were studied. The experimental results showed that these copolymers have goodefficiency in reducing scale depositions of CaCO3, CaSO4 and Ca3 (PO4)2 and they aresuitable for the wide variation of the cycle water hardnes, PH value and temperature. Sothey can be widely used in cooling water for industrial cycles as antiscalant.更多还原
