采用湿式超微粉碎法加工工艺对29％吡·戊悬浮种衣剂进行了研究。对润湿分散剂、增稠剂、成膜剂、防冻剂进行筛选实验,确定了优化配方。制剂经低温和热贮稳定性实验,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 mulit particle method was used to study the 29% pyrene / pentasodium suspension coating agent. The wetting and dispersing agent, thickener, film-forming agent, antifreeze screening experiments to determine the optimal formula. After low temperature and heat storage stability of the preparation experiment, the appearance of no obvious stratification, good water dispersion, the indicators are in line with the standards of suspended seed coating.
