本文研究了由可再生原料制备的三种表面活性剂(APG、AE、脂肪酸钠)复配后的表面性能,主要目的是优化一元、二元、三元复配溶液和不同p H条件下产生最佳润湿性的复配表面活性剂比例。结果表明:几种复配表面活性剂溶液在界面张力、临界胶束浓度和混合胶束化过程中存在协同效应。AE-APG复配后展现了最佳润湿性能。AE-APG-脂肪酸钠三元复配体系在聚四氟乙烯表面和玻璃表面的接触角随着浓度增大而略微减小。此外,所有复配溶液在酸性、碱性及中性介质中都展现了良好的表面性能。与其他p H条件下相比,当p H=7时,AE∶脂肪酸钠(1∶2)、AE:APG(2∶1)和AE∶APG∶脂肪酸钠(1∶1∶1)提高了铝表面和玻璃表面的润湿力。以上研究表明:使用很少的表面活性剂可以达到清洗、润湿和增溶的效果,同时还可降低成本、保护环境。
In this paper, the surface properties of three surfactants (APG, AE, sodium fatty acid) prepared from renewable raw materials were studied. The main purpose of this study was to optimize the production of monobasic, binary, ternary complex solutions and different p H Optimal wettability with surfactant ratio. The results show that there are synergistic effects of several complex surfactant solutions on interfacial tension, critical micelle concentration and mixed micellarization. AE-APG compound shows the best wetting performance. AE-APG-fatty acid sodium ternary complex system Teflon contact surface and the glass surface with the concentration of the contact angle decreased slightly. In addition, all complex solutions exhibit good surface properties in acidic, alkaline and neutral media. AE: fatty acid sodium (1: 2), AE: APG (2: 1) and AE: APG: fatty acid sodium (1: 1: 1) increased at p H = 7 compared to other p H conditions Wetting power on aluminum and glass surfaces. The above studies show that: using a small amount of surfactant can achieve cleaning, wetting and solubilization effect, while reducing costs and protect the environment.
