采用湿式超微粉碎加工工艺,以悬浮率(≥90%)、筛析、热贮[(54±2)℃、14d]稳定性为标准,通过对不同润湿分散剂、增稠剂、防冻剂、消泡剂的筛选,得到了20%虫酰肼·甲胺基阿维菌素苯甲酸盐悬浮剂的最佳制剂配方为虫酰肼19%,甲胺基阿维菌素苯甲酸盐1%,农乳500#1%,宁乳34#4%,NNO0.9%,凸凹棒土1%,乙二醇5%,黄原胶0.1%,消泡剂0.2%,水补足至100%。产品悬浮率≥90%,分散性良好,热贮稳定性合格。
Using wet ultrafine grinding process, the wetting and dispersing agent, thickener and antifreeze were used as the standard in the suspending rate (≥90%), sieving and heat storage [(54 ± 2) ℃, 14d] Agent and defoamer, and the best preparation formula of 20% tebufenozide methicillin-benzoate suspending agent was 19% of tebufenozide, 18% of emamectin benzoate 1% of salt, 500% of agronomy 500%, 4% of natamycin 34%, NNO 0.9%, 1% of attapulgite clay, 5% of ethylene glycol, 0.1% of xanthan gum, 0.2% of defoaming agent, To 100%. Product suspension rate ≥ 90%, good dispersion, heat storage stability qualified.
