十二烷基三甲基氢氧化铵与烷基糖苷复配体系的表面活性和应用性能

Surface Activities and Application Performances of Dodecyl Trimethyl Ammonium Hydroxide and Alkyl Polyglycoside Surfactant Mixtures

研究了十二烷基三甲基氢氧化铵(DTAH)与烷基糖苷(APG-0810)复配体系的稳定性、表面张力及应用性能。结果表明,复配体系总活性物质量浓度小于70 g/L时,溶液透光率大于80%,表现出良好的稳定性,且其表面张力和临界胶束浓度(CMC)均比单一表面活性剂的表面张力和CMC低。复配体系中APG-0810的加入有利于提高十二烷基三甲基氢氧化铵的起泡性、乳化性、润湿力及净洗力。

The stability,surface tension and application performances of dodecyl trimethyl ammonium hydroxide（ DTAH） and alkyl polyglycoside surfactant mixed systems were measured. The results show that the transmittance of mixtures is over 80% when the active matter mass fraction of mixtures is lower than 70 g / L,indicate the mixtures show good stability. The critical micelle concentration and surface tension of mixtures have lower value than single surfactant solution. And the mixtures show better foaming abilities,emulsifying properties,wetting properties and clearing ability than DTAH.
