The scaling phenomenon poses a great challenge for industrial production because of its widespread presence and the complex scaling process. Hence, we report a novel terpolymer (PIA-SAS-AM) scale inhibitor with high efficiency to obstruct the formation of calcium sulfate. Furthermore, the scale inhibition performance and mechanism were further evaluated and systematically investigated. Herein, the various influence factors (monomer ratio, polymerization temperature, initiator content, etc.) on scale inhibition were discussed in detail. By various characterization methods, the terpolymer scale inhibitor was identified, consistent with the expected structure. Based on the static scale inhibition method, the performance of the copolymer on the control of the CSD (calcium sulfate dihydrate) scale was also explored under different external environments (copolymer concentration, retention temperature, calcium concentration, etc.). Especially, the scale inhibition efficiency of CSD reached nearly 100% when the concentration of the copolymer was 16 mg/L. Additionally, the prepared terpolymer scale inhibitor has great aqueous solubility, salt, and heat resistance. This work provides novel insights into inhibiting crystal scaling and offers further guidance on polymer scale inhibitor design.

通过防止结晶来阻止硫酸钙形成的高效三元阻垢剂
结垢现象广泛存在且结垢过程复杂，给工业生产带来了巨大的挑战。因此，我们报道了一种新型三元共聚物（PIA-SAS-AM）阻垢剂，能够高效阻止硫酸钙的形成。进一步对阻垢性能和阻垢机理进行了进一步评价和系统研究。本文详细讨论了各种影响因素（单体配比、聚合温度、引发剂含量等）对阻垢效果的影响。通过各种表征方法，鉴定出三元共聚物阻垢剂，与预期的结构一致。基于静态阻垢方法，还探讨了不同外部环境（共聚物浓度、保留温度、钙离子浓度等）下共聚物对CSD（二水硫酸钙）垢的控制性能。特别是当共聚物浓度为16 mg/L时，CSD的阻垢效率接近100%。此外，所制备的三元共聚物阻垢剂具有良好的水溶性、耐盐性和耐热性。这项工作为抑制晶体结垢提供了新颖的见解，并为聚合物阻垢剂的设计提供了进一步的指导。
