摘要
用不同种类的分散剂、润湿剂、崩解剂、填料进行配方组合,制成制剂后检测其悬浮率、崩解性等指标,确定了36%噻虫啉水分散粒剂的制剂生产配方为噻虫啉36%,萘磺酸盐混合物10%,萘磺酸盐10%,硫酸铵20%,轻质钙33.2%。该配方制剂经热贮稳定性检测,有效成分分解率小于1.1%,悬浮率大于93.3%,润湿时间小于23s,崩解性时间为33s,达到水分散粒剂的产品标准要求。
In this article, different thiacloprid formulations, by the directions of different kinds of dispersing agent and wetting agent, disintegrant agent, were made up and check out according to indexes of suspensibility, disintegration etc. The direction of formulation was chosen, which was made up of thiacloprid 36%, CBZ 10%, naphthalene sulfonate 10%, ammonium sulphate 20%, and calcium carbonate（light） 33.2%. The test of thermal storage stability showed that the decomposing rate of thiacloprid was less than 1.1%, suspension rate more than 93.3%, wetting time less than 23 s, disintegration time less than 33 s, which was in accord with the sandard of quality criterion of WG.
