摘要
本研究结合纳米乳液形成机制及其影响因素,确定了联苯菊酯纳米乳最适表面活性剂为602#和500#,最适助表面活性剂为正丁醇;通过研究联苯菊酯纳米乳液形成过程中表面活性剂、助表面活性剂与联苯菊酯最大加入量的关系,利用多元回归处理分析方法,建立了三者之间的数学模型:Y=-6.0990+1.4105Xc+0.7271Xs,其中Y、Xc、Xs分别为联苯菊酯的最大加入量、正丁醇和表面活性剂的质量百分比。本模型适用范围为:温度20.0~40.0℃;Xc:1%~3.5%;Xs:10%~15%。
The optimum surfactants of bifenthrin nano-emulsions were 602# and 500#,the cosurfactant was n-butyl alcohol,which were developed through the formation mechanism and the factors existed in nano-emulsions.Research was conducted on the relationship between the concentrations of the surfactant and n-butyl alcohol on the maximum amount of bifenthrin that could be added during formation of nano-emulsions.Multivariable regression analysis was used to establish a mathematical model: Y=-6.0990+1.4105Xc+0.7271Xs,Y and Xc and Xs were the maximum amount of bifenthrin and the mass percent of n-butyl alcohol and surfactant respectively.The application range as follows: at 20.0~40℃;Xc: 1%~3.5%;Xs: 10%~15%.
