摘要
简述了聚合物脱挥的传递机理和过程特征,阐述了脱挥传质机理及过程强化,从脱挥工艺和脱挥设备方面综述了聚合物脱挥过程强化的方法,指出了新型的脱挥设备与工艺是实现聚合物高效脱挥的关键,并着重阐述了超临界流体、超声空化、超重力等聚合物脱挥新技术的研究现状和发展趋势。
The transfer mechanism and process characteristics of polymer devolatilization were briefly described,and the mechanism and process intensification of devolatilization mass transfer were introduced.The methods of polymer devolatilization process intensification were summarized from the devolatilization equipment and devolatilization process,and it was pointed out that the new devolatilization equipment and process were the key to realize the high-efficiency devolatilization of polymer.The research status and development trend of new technologies of polymer devolatilization,such as supercritical fluid,ultrasonic cavitation and high gravity were emphatically expounded with 62 refe-rences.
