利用热重 -差示扫描量热 -质谱 ( TG-DSC-MS)联用技术对溶胶 -凝胶 ( Sol-Gel)法热压烧结制备碳纳米管 ( CNT) /Si O2 复合材料过程中的热分解行为特性进行了表征研究。采用多离子检测模式预定测量热分解生成的 C+ ( m/z1 2 )、OH+ ( m/z1 7)、H2 O+ ( m/z1 8)、CO2 + ( m/z2 8)等 9种正离子。实验发现 :用溶胶 -凝胶...
采用TGDSCQMSFTIR同步动力学技术对RDX的热分解过程进行了研究，结果表明，RDX在熔融之后发生分解，可以确定RDX的产物有C、H2O、CH2O、N2O、CO、CO2、NO2，可能有CH4和NH3，而几乎没有NO。采用多元非线性拟合技术进行动力学参数计算，结果表明，RDX的分解过程大致可以分为3个连续步骤，第1步反应的活化能为235kJ/mol，指前因子log(A/s-1)为22，反...
