【摘要】 本文通过对工业碱中非有效成分的单因素分析和正交多因素实验，探讨了影响三元复合体系界面张力的主要因素，结果表明，碱中Fe3+、Mg2+、Ca2+对三元复合体系的界面张力的影响不大，钠离子是影响三元复合体系界面张力的主要因素，提出了钠离子对三元复合体系的影响机理，即Na+离子浓度的变化会使表面活性剂分子在油水界面上形成的吸附双电层及表面活性剂亲水头基的静电斥力发生改变。另外，通过对单因素和水质因素的评价，对主要因素进行评价分析，并结合工业碱的成分拟合数据，确定了油田用工业碱的使用标准。更多还原

【Abstract】 The main factors to affect the interfacial tension of the ternary compound system bythe non-active ingredients in industrial alkali were studied via univariate analysis andorthogonal multi-factor tests. It was found that Fe3+, Mg2+, Ca2+in alkali had less effecton the interfacial tension of the ternary complex system, but sodium ion affected theinterfacial tension of the ternary compound system significantly. The mechanism of theeffect of sodium ion on the ASP system was proposed, and the absorption double electriclayers between oil-water interfaces formed from the surfactant molecules and theelectrostatic repulsion come from the hydrophilic head groups in surfactant moleculeswould change with the concentration of Na ions. The using standard of industrial bases inoil field was given based on the evaluation of single factors and water quality factors, theevaluation and analysis of major factors, and the fitted data of the components ofindustrial alkali.更多还原
