Numerical Modeling on the Accelerated Aging of JOB-9003 Explosive
From the thermogravimetry (TG) curves of JOB-9003 explosive at the heat rate of 5, 10 and 20 K-min-1 respectively, the thermal decomposition activation energy, pre-exponential factor, mechanism function and kinetic equation of JOB-9003 explosive were calculated by Ozawas equation and the decomposition extent. Based on the derived kinetic equation, the density, composition and heat of formation on different decomposition extent of JOB-9003 explosive, at accelerated aging temperatures 70℃, 75℃, were computed respectively. The detonation parameters of JOB-9003 explosive under different aging condition were computed by means of the VLWR code.
