摘要:
为了研究不同粒度高氯酸铵(AP)对RDX热稳定性的影响,以及AP对RDX基混合炸药能量释放的影响规律,设计了不同AP含量和粒度的AP/RDX混合炸药,并测试了其爆热和爆速。结果表明,100~150 μm、10~13 μm和2 μm 3种粒径的AP对RDX的热分解都起到了促进作用,使RDX的分解峰温降低,分别由433℃降至368℃、417℃降至365℃、375℃降至321℃;随着AP的加入及其粒度的减小,混合物中RDX的表观活化能也越小,由纯RDX的206 kJ/mol分别减至188、170和157 kJ/mol;随着AP质量分数由0提高到60%,爆速和爆热均呈增大趋势,爆速由5 390 m/s增至8 315 m/s,爆热由1 610 kJ/kg增至5 396 kJ/kg;随着AP粒度的减小,爆速有所增大,分别增至5 863、5 902和5 931 m/s,粒度对爆热没有明显影响。
Abstract:
In order to investigate the effect of different particle sizes of ammonium perchlorate (AP) on the thermal stability of RDX and the effect of AP on the energy release rule of RDX-based composite explosives, AP/RDX composite explosives with different AP content and particle sizes were designed, and their heat of explosion and detonation velocity were tested. The results show that the AP with particle sizes of 100-150 μm, 10-13 μm and 2 μm all have acceleration on the decompostion of RDX, and the decomposition peak temperature of RDX decreases from 433℃ to 368℃, 417℃ to 365℃ and 375℃ to 321℃, respectively with the decrease of particle size of AP. As the addition of AP particle and its size decreases, the apparent activation energy of RDX in the mixtures decreases from 206 kJ/mol to 188, 170 and 157 kJ/mol, respectively. With the mass fraction of AP increases from 0 to 60%, the detonation velocity and heat of explosion increase from 5 390 m/s to 8 315 m/s and from 1 610 kJ/kg to 5 396 kJ/kg, respectively. As the particle size of AP decreases, the detonation velocity increases to 5 863, 5 902 and 5 931 m/s, respectively, while there is no significant impact on the heat of explosion.
