摘要
研究了C12～14脂肪醇聚氧乙烯聚氧丙烯醚AEO9Pm(P=0、2和4,P=0即为AEO9)的性能,包括平衡表面张力、动态表面张力、粘度、泡沫、润湿和乳化性能.实验结果表明:随着PO数的增加,临界胶束浓度、泡沫体积和粘度降低,动态表面张力下降速度增加,润湿性和乳化能力提高.
Abstract
The performance C12-14 fatty alcohol ethoxylates propoxylates AEO9Pm(P=0,2 and 4)were studied.Equilibrium surface tension,dynamic surface tension,foam,viscosity,wetting and emulsification performance of the AEO9Pm were tested.The results were as follows:with increasing PO number for AEO9Pm,critical micelle concentration,foam volume and viscosity decrease,the rate of dynamic surface tension descent increases,wetting and emulsification performance increase.
