摘要
用U形管电泳仪在电压为30V条件下测定了造纸用羧基丁苯胶乳(牌号XSBRL46C)的ξ电位;研究了十二烷基硫酸钠(SDS)、十二烷基苯磺酸钠(SDBS)、电解质溶液的浓度及pH值对ξ电位及稳定性的影响。结果表明:SDS和SDBS的浓度超过临界胶束浓度后,ξ电位增值减小;当乳液pH值小于7或大于9时,ξ电位减小,乳液稳定性降低。
The ξpotential of carboxylated styrenebutadiene rubber latex for paper making was determined by U-tube electrophoresis apparatus at 30V. The effects of concentrations of sodium dodecyl sulfate and sodium dodecylbenzene sulfonate, concentration and pH value of electrolyte solution on the ξpotential and stability were studied. The result showed that the experimental data were in good agreement with the theoretical values.
