| 中文摘要: |
| 目的 为提高聚环氧琥珀酸(PESA)的阻垢缓蚀综合性能，拓展其应用范围，将2-氨基乙磺酸(SEA)引入PESA分子中，合成聚环氧琥珀酸衍生物(SEA-PESA)并应用于海水环境。方法 将PESA和SEA缩合制备了SEA-PESA，用傅里叶红外光谱和核磁氢谱表征其结构。研究了 SEA-PESA及其四元复合配方在天然海水中的缓蚀和阻垢等综合性能。结果 在海水环境中，SEA-PESA质量浓度为160 mg/L，对Q235钢片的缓蚀率为61.82%，而PESA仅为52.17%。PESA和SEA-PESA的四元复合配方的缓蚀率分别高达88.87%、96.99 %，腐蚀速率分别为0.065 52、0.017 72 mm/a，SEA-PESA四元复合配方缓蚀效果明显优于PESA，更好地契合了国标的要求。SEA-PESA四元复合配方以抑制阳极为主，是一种阳极型缓蚀剂;在海水中也表现出良好的阻垢性能，在10 mg/L用量下阻垢率达100%。结论 本研究证实了SEA-PESA用于冷却系统和热脱盐工艺过程中，特别是海水环境中抑制腐蚀和结垢方面的潜能，应用前景广阔。 |
| 英文摘要: |
| In order to improve the comprehensive scale and corrosion inhibition performance of polyepoxysuccinic acid (PESA) and expand its application range, 2-aminoethylsulfonic acid (SEA) was introduced into PESA molecule to synthesize a polyepoxysuccinic acid derivative (SEA-PESA) and applied in seawater environment. SEA-PESA was synthesized by condensation of PESA and SEA, and the structure of SEA-PESA was characterized by Fourier-infrared spectroscopy and 1HNMR. Comprehensive property of scale and corrosion inhibition were studied on SEA-PESA and its quaternary formulation in natural seawater. In seawater environment, when SEA-PESA concentration is 160 mg/L, and the corrosion inhibition efficiencies of Q235 carbon steel is 61.82%, while that of PESA is only 52.17%. The corrosion inhibition rates of the quaternary formulations of PESA and SEA-PESA were 88.87% and 96.99%, respectively, and the corrosion rates were 0.06 552 mm/a and 0.017 72 mm/a. The corrosion inhibition effect of the quaternary formulations of SEA-PESA was better than PESA’s, which better met the requirements of national standards. SEA-PESA quaternary formulation is an anodic corrosion inhibitor, which mainly inhibits the anode. It also showed good scale inhibition performance in seawater, and the scale inhibition rate reached 100% at the dosage of 10 mg/L. This study confirmed the potential of SEA-PESA for corrosion inhibition and scaling inhibition in cooling systems and thermal desalination processes, especially in seawater environment, and has a broad application prospect. |
