CL-20/HMX混合体系的热分解

Thermal decomposition of CL-20/HMX mixed system

用高压差示扫描量热法(PDSC)研究了六硝基六氮杂异伍兹烷/奥克托今(CL-20/HMX)混合体系在常压及高压下的热分解行为,比较了混合体系在不同压强下的热分解特征,用Ozawa法获得了0.1、1、3 MPa下混合体系中CL-20的热分解动力学参数,讨论了混合体系组分的混合比和压强对其热分解动力学参数的影响。结果表明,随着压强的增大及HMX含量的增高,CL-20分解表观活化能提高。

The thermal decomposition behavior of CL-20/HMX mixed system under different pressure was investigated by means of high-pressure DSC, and the thermal decomposition characteristics of the mixed systems under different pressure were compared. The thermal decomposition kinetic parameters of CL-20/HMX mixed system under 0. 1 MPa, 1 MPa,3 MPa pressure were calculated by Ozawa method. The effects of ingredient mixture ratio and pressure on thermal decomposition kinetic parameters were analyzed. The results show that the apparent activation energy of CL-20 in the system increases with pressure and HMX content.
