50%二氰蒽醌悬浮剂的研制

Preparation of Dithianon 50% Suspension Concentrate

采用流点法对二氰蒽醌悬浮剂的润湿分散剂进行了初筛,利用黏度法确定了润湿分散剂的最佳用量通过分析二氰蒽醌悬浮剂54℃下热贮前后平均粒径、悬浮率等物化性能确定了50%二氰蒽醌悬浮剂的最佳配方,结果表明,该产品热贮14d后,悬浮率在97%以上,分解率<2%,其他各项指标均符合悬浮剂的要求。

The components of wetting dispersants for DithianonSuspension Concentrate formulationwere screened by flowing point method.The optimum contents of the components were confirmed by mass fraction-viscosity curve.Combined with the granular size before and afterstorage at 54℃,the best formula of dithianon 50%suspension concentrate was determinedbased on the results of suspension ratio and viscosity.The experimental results showed that the suspension ratio was over 97%,the decomposition rate of the active ingredient was less than 2%,and the other parameterscomplied with the requirements for SC formulation.
