摘要
比较研究了水、氟利昂、HCFC141b 发泡聚氨酯泡沫塑料的热分解过程。采用两种方法建立动力学方程并求解了各动力学参数,根据结果分析了脲段含量对聚氨酯泡沫塑料的热分解表观活化能的影响。
Thermal degradation of water,CFC 11,HCFC 141b blown polyurethane samples are studied by a thermolgravimetric method.Kinetics equation is set up via Coats Redfern and Ozawa Flynn and various kinetical parameters are worked out. The effect of urea concentration on apparent activation energies of the degradation process is analyzed.
