-
摘要: 研究了液膜破损机理, 讨论了某些参数即各种表面活性剂及浓度, 各种载体对提铜液膜体系破损的影响。实验结果表明, 在一定范围内, 随着表面活性剂浓度的增加;液膜的稳定性增加, 含有阴离子的表面活性剂(LMS-2)的LIX984的液膜体系最稳定, 其次为含有高分子非离子的表面活性剂(LMA-1), 而聚胺型的表面活性剂(L113B)稳定性最低。合理选择表面活性剂的种类及用量, 有助于提高液膜体系的稳定性。Abstract: The effects of surfactants and their concentration on breakage of emulsion membrane have been examined in experiment.The result show that the breakage ratio will increase as the concentration of surfactants in membrane phase increases.The emulsion membrane containing negative ionic(LMS-2)is not the easiest to break, and membrane contain hi gh molecular nonionic(LMA-1).The breakage of membrane containing polyamine type nonionic(L113B)is largest.Reasonable selection of surfactant and its concentration in membrane is helpful for improving the stability of emulsion membrane.
