使用激光粒度分析仪,对生物基固化剂718A微胶囊进行粒径分布分析。微胶囊制备:分别在转速2000rpm,2500rpm,3000rpm和3500rpm下,以NSF3007C作为乳化剂,乳化剂浓度2wt%,温度40℃,持续4h。
Using a laser particle size analyzer, the particle size distribution of the bio-based curing agent 718A microcapsules was analyzed. Microcapsule preparation: NSF3007C was used as an emulsifier at a rotational speed of 2000rpm, 2500rpm, 3000rpm and 3500rpm, respectively, with an emulsifier concentration of 2wt% and a temperature of 40 ° C for 4h.
