福建农林大学生物农药与化学生物学教育部重点实验室近期成功制备2.5%毒死蜱微球悬浮剂。研究人员首先采用流点法,对毒死蜱微球悬浮剂的润湿分散剂种类进行了筛选,在所筛选的10种分散剂中,SOPA和N-甲基脂肪酰基牛磺酸盐的流点值较小,分别为0.5032和0.4656。进一步筛选了增稠剂、防冻剂,较优配方为:11.2%毒死蜱聚乳酸微球、2.5%SOPA、2.5%N-甲基脂肪酰基牛磺 Fujian Agriculture and Forestry University, Pesticide and Chemical Biology Key Laboratory of Ministry of Education recently successfully prepared 2.5% chlorpyrifos microsphere suspending agent. The researchers first using flow point method, chlorpyrifos microsphere suspending agent wetting and dispersing agent were screened in the selected 10 kinds of dispersant, SOPA and N-methyl fatty acyl taurate flow point value Smaller, respectively 0.5032 and 0.4656. The thickeners and antifreeze were further screened. The optimal formulation was: 11.2% chlorpyrifos PLA beads, 2.5% SOPA, 2.5% N-methyl fatty acyl taurine
