铝粉含量及粒度对炸药驱动能力的影响

Effect of Aluminum Content and Particle Size on Acceleration Ability for Explosives

通过一维平板加速试验方法,研究了铝粉含量及粒度对含铝浇注PBX炸药驱动能力的影响。测试分析了不同铝粉含量或粒度的炸药配方金属加速能力,并进行了工程验证试验。结果表明,在铝含量一定范围内,炸药驱动破片金属加速能力随着铝粉含量增加先增加后减小,铝粉含量存在一个最优配比;铝粉尺寸对能量释放有影响。

The influence of aluminum content and particle size on acceleration ability of aluminized cast PBX was studied by the metal plate acceleration experiments. The metal acceleration ability of different aluminum pow- der content or particle size of the explosive formulation was tested. And the engineering verification tests were car- ried out. The results show that the explosion acceleration ability to metal plate is increasing with the increasing of aluminum content in a range. The perfect content is 15 percent in this study. The size of aluminum powder affects the energy release.
