摘要 分别采用激光粒度仪、光学显微镜、高效液相色谱、X-射线衍射等方法对球形化处理前后的奥克托今(HMX)颗粒的形貌、化学纯度、晶体缺陷等晶体品质进行了表征,采用TG-DSC和5s爆发点实验研究了其热性能,测试了其撞击感度、摩擦感度和静电感度。结果表明,球形化HMX颗粒基本为球形,表面光滑,颗粒透光均匀,内外缺陷少,热稳定性提高,颗粒密度分布集中,以HMX为基的浆状炸药的流散性明显改善,机械感度和静电感度变化不明显。 The crystal quality and properties of spherical HMX such as particle size distribution, morphology, particle defects, chemical purity, thermal properties and sensitivities were characterized by laser light scattering, optical microscopic, optical microscopic with matching refractive index, density gradient technique, differential scanning calorimetry (DSC)and sensitivity tests. Resuits show that the crystal quality of HMX particles is improved after being spherically disposed. Comparing with original HMX particles, spherical HMX particles become more round and more smooth, their internal and surface defects are reduced, the particle diaphaneity is better, the particle density distribution becomes narrow, thermal stability and rheology of explosive based on spherical HMX particles are improved.
