采用湿法超微粉碎法制备40%硫磺·多菌灵悬浮剂,并通过流点法和优化组合法对润湿分散剂、增稠剂、防冻剂、防腐剂、消泡剂等助剂进行试验筛选,最终确定了优选配方。并对优选配方制备的悬浮剂产品进行性能检测,结果表明产品质量稳定、悬浮率高、析水率低、低温稳定性和热贮稳定性合格、各项指标符合悬浮剂的标准要求。 40% sulfur and carbendazim suspending agent was prepared by wet ultrafine grinding method, and the additives such as wetting and dispersing agent, thickener, antifreeze, preservative and antifoaming agent were carried out by flow point method and optimization combination method Test screening, and ultimately determine the preferred formula. The results showed that the product has the advantages of stable quality, high suspension rate, low water loss rate, low temperature stability and heat storage stability. The indexes are in line with the standard requirements of SC.
