采用湿式超微粉碎法加工工艺对15%吡.多悬浮种衣剂进行了研究。对润湿分散剂、增稠剂、成膜剂、防冻剂进行了筛选试验,确定了最优配方。经低温和热贮稳定性试验,制剂外观无明显分层,水中分散性良好,各项指标均符合悬浮种衣剂相关标准。
The wet micronized grinding process was used to study the 15% The wetting and dispersing agent, thickener, film-forming agent, antifreeze screening tests to determine the optimal formula. After low temperature and heat storage stability test, there is no apparent delamination of the appearance of the preparation and good dispersibility in water. All indexes are in accordance with the standards of suspended seed coating.
