乳化剂用量对石蜡微胶囊性能的影响

The Effect of Emulsifier Dosage on the Performance of Microencapsulated Paraffin

针对太阳能利用以及一些蓄热场合,选取了熔点合适的石蜡,以脲醛树脂为囊壁,采用原位聚合法制备了石蜡—脲醛树脂微胶囊,拟将此微胶囊添加到上述应用场合的传热流体中,提高传热流体的热容。探讨了乳化剂用量对微胶囊蓄热性能和表观形态的影响,可望为工业化生产应用、开发新的储热材料提供技术指导。

Certain paraffin was chosen for core material,which was adapted to solar energy utilizing and the other thermal storage system.Urea-formaldehyde polymer was used as wall material.Urea-formaldehyde microencapsulated paraffin by means of situ polymerization,which was hoped to be added into heat transfer fluid of solar energy utilizing and other thermal storage system to increase the specific heat of fluid.The effect of emulsifier dosage on the performance of microencapsualtion was studied.The results of experiment were analyzed,and the guidance is brought up to develop industrial production and new thermal storage material.
