| 摘 要： | 用T-JUMP/FTIR技术研究了模拟燃烧条件下RDX的热裂解过程.通过分析裂解产物随时间的分布规律及温度与压力对裂解过程的影响,提出了RDX可能的快速热裂解机理及影响快速热裂解机理的因素.结果表明,RDX裂解气相产物主要有CO2、N2O、NO2、HNCO、NO、CO和HCN,且在不同的测试条件下产物的相对含量有明显变化:在600℃、0.1～0.4 MPa条件下,裂解5 s以内的NO2与NCN含量比随压力的升高而下降;HCN与N2O含量比随压力的提高而增大;在0.1 MPa压力条件下,随着温度的升高,HCN与N2O的含量比趋向于增大.RDX快速热裂解的初期存在两个竞争反应,即C-N和N-N键的断链竞争反应;提高温度和在0.1～0.4 MPa压力范围内提高压力对生成HCN的N-N键断裂反应有利.

| Abstract: | The pyrolysis process of RDX was investigated by using T-JUMP/FTIR test.The influence of temperature and pressure on the fast thermolysis process and the distributing law and relative quantity of gas products with respect to temperature and pressure were analyzed.The possible fast thermolysis mechanism of RDX was validated.The factors affecting the fast thermolysis mechanism were analyzed.The results show that the main gas products of RDX thermolysis are CO2,N2O,NO2,HNCO,NO,CO and HCN,which relative content... |
