【摘要】 为了研究不同敏化剂对水浴加热后乳化炸药爆炸威力的影响,将含有不同敏化剂的乳化炸药经水浴加热不同时间后进行水下爆炸实验并得到压力时程曲线,通过对压力时程曲线进行计算得到相应的爆炸性能参数。结果表明,不同敏化剂敏化的乳化炸药爆速、压力峰值、冲量、比冲击波能、比气泡能以及总能量总体上随着水浴加热时间增加而降低,其中,NaNO₂敏化的乳化炸药总能量在水浴加热1h后降低量大于10%,物理敏化的乳化炸药总能量在水浴加热1h后降低量小于5%。另外,NaNO₂敏化的乳化炸药在水浴加热后容易散失雷管感度,而物理敏化的乳化炸药不存在散失雷管感度现象。更多还原

【Abstract】 In order to study effects of different sensitizers on explosion power of emulsion explosives after water-bath heating,the pressure-time curves of emulsion explosives with different sensitizers after different time durations of waterbath heating were measured through underwater explosion tests. The corresponding explosion performance parameters were calculated using the curves. The results showed that detonation velocity,peak pressure,impulse,specific shock energy,specific bubble energy and total energy of emulsion explosives with different sensitizers decrease with increase in waterbath heating time; the total energy of emulsion explosives sensitized by NaNO₂ decreases by more than 10% after one hour of water-bath heating,while that of emulsion explosives sensitized by physical sensitizer decreases by less than 5% after one hour of water-bath heating; emulsion explosives sensitized by NaNO₂ is easy to lose cap sensitivity after water-bath heating,but there is not such a phenomenon for emulsion explosives sensitized by physical sensitizer.更多还原
