摘要
通过试验筛选出15%毒死蜱颗粒剂的优选配方及小试工艺。采用浸渍法工艺,分别探索天然载体和人工挤压造粒载体,制备高含量的缓释型颗粒剂产品的优选配方及小试工艺条件。产品质量稳定合格,颗粒流动性好,热贮(54±2℃,14d)分解率≤5%,破碎率≤10%,配方对载体材料的适应性良好,可满足不同生产成本及缓释用途的用药需求。
The optimum formula and laboratory scale processof chlorpyrifos 15%granules were screened out by tests.The slow-release granules with high aicontentwere preparedbyimmersion processto use natural and artificial carriersproduced by extrusion pelleting respectively.The productquality was proved to be stable with good flowability.After stored at 54±2℃ for 14 d,the decomposition rate of the prepared sample was less than 5%,and the broken rate was less than10%.The formula showed good adaptability for carried particles and could meet various market demandsfor slow-release products with different production cost.
