农药悬浮剂润湿分散剂研究进展

Research Progress of Wetting Dispersant in Pesticide Suspension Concentrate

农药悬浮剂是将不溶于水的固体原药分散于水中而形成的分散体系。为了增加悬浮剂的稳定性,通常须加入一定量的适宜分散剂。因此,高性能新型润湿分散剂的研发具有重要意义。文章简要介绍了润湿分散剂的分类和稳定原理,讨论了农药悬浮剂研制时选择润湿分散剂应遵守的规则和选择方法,并论述了润湿分散剂研究进展情况。

Pesticide suspension concentrate is the dispersion system formed by solid TC which will not dissolve in water dispersed in water. In order to increase the stability of suspension concentrate, usually to be adding a certain amount of suitable dispersant. Therefore, it has important significance of new high performance wetting dispersant R ＆ D. This paper briefly introduced the classification and stability principles of wetting dispersant, described the rules and selection approaches of various wetting dispersants in different pesticide suspension concentrates, and discussed the progress in study of wetting dispersant.
