本文研究了不同结构的烷基聚氧乙基硫酸盐与一给定的石油磺酸盐的复配物体系的抗盐性能。结果表明,烷基聚氧乙基硫酸盐表面活性剂可以显著地提高体系的抗盐尤其是抗钙能力。这些体系均具有超低界面张力(10~(-3)毫牛顿/米)。
In this paper, we studied the salt-resistance of different structure of alkyl polyoxyethyl sulfate and a given petroleum sulfonate complex system. The results show that the alkyl polyoxyethyl sulfate surfactant can significantly improve the system of salt resistance, especially calcium resistance. These systems all have ultra-low interfacial tension (10 -3 mN / m).
