摘要:

基于机械物理法的基本原理,以废旧热固性酚醛树脂为研究对象,分析其回收机理。采用响应面法中的Box-Behnken模式,对回收工艺参数中最主要的三个因素(转速、时间和入料粒径)进行试验优化设计,并建立了多元二次模拟方程。试验结果表明:转速、时间和入料粒径对热固性酚醛树脂降解的显著程度由高到低分别为转速、入料粒径、时间,热固性酚醛树脂降解率最大时的回收工艺参数是转速2940r/min、时间95min、入料粒径071mm。

Abstract:

Based on the fundamental of mechanical physical method, the waste thermosetting phenolic resins was researched and the recovery mechanism was analysed. By using Box-Behnken model of response surface methodology, a series of experiments for optimizing three main factors (speed, time and size) of recovery process parameters were designed and a quadratic polynomial equation model was constructed. The results show that: the order of the important effects of speed, time and size on the degradation of thermosetting phenolic resins is speed>size>time,when the degradation rate is the biggest,  the recovery speed,time and size for waste thermosetting phenolic resins recycling  are 2940r/min,95min,and 071mm respectively.

Key words: thermosetting phenolic resin, mechanical physical method, response surface methodology, recycling
