摘要
为了明确农药制剂配方中不同类型助剂对药液性能的影响,用旋滴法测定了分散剂、润湿剂及复合表面活性剂体系水溶液的表面张力变化.结果表明,分散剂DC04、润湿剂WLNO 200与其它农药助剂比较,具有较高的表面活性,二者复配后表面活性剂体系水溶液的表面张力曲线与润湿剂的表面张力曲线相近,复配比在3∶1时可产生明显的协同效应,表面张力最低.
In order to study the effect of pesticide adjuvant on the property of pesticide solution, the surface tension of the solution added with dispersant, wetting agent and their combination were determined by spinning drop method. The results showed that the treatments added with dispersant DC04 and wetting agent WI.NO 200 had higher surface activity, the curves of the surface tension of the combination treatment and the wetting agent treatment were similar, and the surface tension reached to the lowest when the ratio of the dispersant to the wetting agent was 3： 1, under this ratio the synergistic reaction of the dispersant and the wetting agent was obvious.
