摘要:

随着“绿色化学”的发展, 防腐阻垢剂也逐步趋向环境友好型. 通过电导率法探讨了不同温度及浓度下聚环氧琥珀酸(polyepoxysuccinic acid, PESA)的阻碳酸钙垢、碳酸钡垢和硫酸钡垢的性能. 结果表明: PESA的阻垢性能良好, 且随着浓度的增加, 其阻碳酸钙垢和硫酸钡垢的性能也不断增强; PESA阻碳酸钡垢的性能随其浓度的增加先增强后减弱, 并在40 mg/L时达到峰值; 随着温度的升高, PESA阻碳酸钙垢的性能逐渐减弱, 而阻碳酸钡垢和硫酸钡垢的性能逐渐增强. 实验结果证明, PESA是一种优良的阻垢剂, 适用于在一般温度下阻碳酸钙、硫酸钙及硫酸钡型的垢. 此外, 电导率法具有操作简便、快捷的特点, 适用于针对以上几种垢的阻垢性能研究.

Abstract:

With the proposal and development of green chemistry, corrosion inhibitors tend to be environmental friendly. This paper explores the anti-scale performance of polyepoxysuccinic acid (PESA) on CaCO3 scale, BaCO3 scale, BaSO4 scale at different temperatures and different concentrations with conductivity measurement. The results showed that the ability of anti-scale performance of PESA was good. With the increasing of its concentration, the anti-scale performances of PESA on CaCO3 and BaSO4 continued to strengthen, while BaCO3 decreased after the concentration rised to 40 mg/L. With temperature
increasing, its anti-scale performance of CaCO3 scale decreased, while BaCO3 scale and BaSO4 scale increased. Therefore, PESA is an excellent anti-scale inhibitor suitable for inhibiting CaCO3, CaSO4, and BaSO4 at normal temperature of the factory. Moreover, the conductivity measurement is simple and fast, and it can be used in exploring the anti-scale performance of scale inhibitors.
