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 TATI3 based PI3X 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 oressure does not change ohviouslv.
