40%唑醚·啶酰菌水分散粒剂配方及工艺研究

Research on Formulation and Technology of Pyraclostrobin+Boscalid 40% WG

通过对润湿剂、分散剂、填料等进行筛选,确定40%唑醚·啶酰菌水分散粒剂配方。分散剂采用Mortwet D425(4%)、AJ-002(2%)、REAX910(2%)与聚羧酸盐分散剂SP-2836(2%)或Geropon T36(2%)复配,以K12为润湿剂,玉米淀粉为填料。所制水分散粒剂有较高的悬浮率,较好的热稳定性。生产中水分散粒剂烘干优选流化床沸腾烘干方式,不同的捏合设备以及捏合时间对产品性能有影响,但粉碎方式对产品影响不大。

The preparation of pyraclostrobin ＋ boscalid 40% WG was studied by screening different wetting agents, dispersants and carriers. Mortwet D425 （4%）, AJ-002 （2%）, REAX910 （2%） mixed with SP-2836 or GeroponT36 （2%） as dispersant, K12 used as wetting agent, corn starch as filler was put in pyraclostrobin ＋ boscalid 40% WG. The WG had high suspension rate and good thermal stability. Fluidized drying method was suitable for preparation WG, kneading equipment and mixing time affected the performance of the product.
