摘要/Abstract

摘要： 通过自由基聚合法，以马来酸酐（MAH）、2丙烯酰胺基2甲基丙磺酸（AMPS）和丙烯酰胺（AM）为反应单体，成功制备了P(MAH-AMPS-AM)共聚物，并将其应用于循环水阻垢。利用FTIR对其化学结构进行了表征，以阻垢率为研究对象，详细探讨了P(MAH-AMPS-AM)共聚物的阻垢效果与投加量、水样温度及溶液pH之间的关系；进一步通过SEM考察了阻垢剂对钙垢晶体的影响。结果表明，P(MAH-AMPS-AM)共聚物对CaCO3和CaSO4均具有良好的阻垢性能，在阻垢剂的投加量为15 mg/L时，其阻碳酸钙垢的阻垢效率达到93.8 ％；其投加量为18 mg/L时，阻硫酸钙垢的阻垢效率达到92.8 %，且在水样温度为80 ℃时仍具有较好的阻垢效果;P(MAH-AMPS-AM)共聚物能有效破坏钙垢晶体的规整性，使晶体产生大量缺陷，从而起到抑制结垢的能力。

Abstract: A maleic anhydride-co-2-acrylamide-2-methylpropanesulfonic acid-co-acrylamide copolymer was synthesized by radical polymerization using maleic anhydride (MAH), 2-acrylamido-2-methylpropanesulfonic acid (AMPS) and acrylamide (AM) as comonomers, and its structure was characterized by Fourier-transform infrared spectroscopy. This copolymer was used as a scale inhibitor for circulating water, and the effects of inhibitor concentration, water temperature and pH value on the inhibiting effect of the inhibition system were investigated. Moreover, the calcium scaling morphology was observed by scanning electron microscopy. The results indicated that this copolymer could act as a good scale inhibitor for CaCO3 and CaSO4 and achieved a scale inhibition rate of 93.8 % for CaCO3 at the concentration of 15 mg/L and 92.8 % for CaSO4 at the concentration of 18 mg/L. In addition, this copolymer exhibited high inhibition efficiency at a water temperature of 80 ℃, and it could destroy the regularity of calcium scale crystals, thus resulting in a large number of defects in the calcium scale crystals and giving a scale-inhibiting effect.
