75℃下TATB基高聚物粘结炸药爆轰性能

摘要

为研究TATB基高聚物粘结炸药（ PBX）在高温下的爆轰性能，采用标准隔板试验、电测法、ZWB253-2008标准方法和圆筒试验测试了其在25℃和75℃下的冲击波感度、爆速、爆压及比动能。结果表明，与25℃相比，75℃下TATB基PBX的冲击波感度和比动能增大，爆速降低，爆压无明显变化。%To study the detonation performance of TATB based polymer bonded explosive ( PBX) at high temperature, the sensitivi-ty to shock wave, detonation velocity, detonation pressure and specific kinetic energy of the TATB based PBX at 25 ℃and 75 ℃were tested by standard gap test, electrometric method, standardization method, ZWB253-2008 and cylinder test, respectively. Results show that in comparison with those of 25℃, the shock wave sensitivity and specific kinetic energy of PBX at 75℃increa-ses, whereas the detonation velocity decreases slightly and the detonation pressure does not change obviously.
