摘要

为了研究结晶状敏化剂意外混入乳化炸药中的危险性，采用杜瓦瓶恒温试验法研究结晶状亚硝酸钠对硝酸铵、乳胶基质和乳化炸药热稳定性的影响。试验结果表明，在400 g样品中添加10 g亚硝酸钠的试验条件下，混合体系热稳定的临界温度范围分别为：硝酸铵40～45℃，乳化炸药45～50℃，乳胶基质则大于100℃。硝酸铵、乳化炸药和乳胶基质中的结晶亚硝酸钠临界添加量分别< 1 g，2 g和10 g。可见样品体系热稳定性：硝酸铵< 乳化炸药< 乳胶基质。样品含水量的增加可提高混有亚硝酸钠样品混合体系的热稳定性。

Abstract

To study the unexpected interfusion of crystalloid sensitizer on the safety of emulsion explosive

Dewar test was employed for studying the influence of crystalloid sodium nitrite (NaNO2) on the thermal stability of ammonium nitrate (AN)

emulsion (ANE)

and emulsion explosive (EE). The results show that when adding 10 g NaNO2 into 400 g samples

the threshold temperature of samples are AN 40—45℃

EE 45—50℃

and ANE >100℃. The critical adding amounts of NaNO2 for AN

EE and ANE are 1 g

2 g and 10 g

respectively. The order of their thermal stability is accordingly as follows: AN< EE< ANE. The increasing water content in sample is helpful for the thermal stability of the sample systems with mixed NaNO2.
