| 摘 要： | 采用激波管方法研究了酚醉树脂在温度1100K～1800K范围之间的热解过程.在激波管高温和短实验时间条件下,分析了实验样品颗粒在高温气相中的传热过程,讨论了样品颗粒达到热平衡的条件.通过色谱和质谱方法检测热解产物,获得了酚醛树脂高温热解产物分布和热解速率常数.酚醛树脂高温热解最主要的产物为水、一氧化碳、氢、乙炔和苯.温度1400 K将酚醛树脂热解分为高温和低温区,分别表现出不同的热解速率常数与温度的关系.

| Abstract: | The pyrolysis of phenolic resin was studied in a single-pulse shock tube at high temperatures between 1100 K and 1800 K.Considering the very high temperature and short duration time in a shock tube,the heat transfer process of sample particles in high temperature gas was analyzed and the heat equilibrium conditions between the phenolic resin powder and the ambient high temperature gas was also discussed.The pyrolysis product distribution and the pyrolysis rate constants of phenolic resin were determined usi... |
