摘要
Abstract
This thesis mainly studies the composite stabilizer of a series of anionic/cationic sur-factant ,and selects sodium dodecyl benzene sulfonate(SDBS)and tetradecyl trimethyl ammonium chloride(TTAC)as velvet pouch formation system .Adding polymer into the system under the conditions that the total concentration of surfactant is 0 .02 mol/L and V(SDBS)∶V(TTAC)=7∶3 ,the viscosity of the system increases ,surface tension reduces ,friction between the mole-cules increases ,binding force of the surface molecules decreases ,and all of that make the system stabilization .Analysis of the particle size shows that the particle size becomes larger and distribu-ted evenly after adding polyving akohol(PVA) of 0 .2% mass fraction into the velvet pouch sys-tem .When studying the stability of the system ,velvet pouch system would be damaged by CaCl2 and MgCl2 ,while the stability would become better by adding PVA ,and could not be easily dam-aged by salt .关键词
