摘要:
采用破乳剂Tween80，在温度70 ℃、搅拌速度400 r/min的条件下将乳化基质、乳化炸药在400 mL的水溶液中进行破乳。检测破乳过程中水溶液的电导率变化，绘制电导率-时间曲线，以此判断乳化基质、乳化炸药储存期间的稳定性。论述了实验原理及影响实验的因素。实际检测了乳化基质和乳化炸药在自然储存及冷冻储存条件下电导率-时间曲线的变化规律。检测结果与显微镜观察破乳情况和实际爆破性能对比表明，电导率法检测得到的结论与显微镜观察的析晶破乳状态及实际爆破性能基本一致。最终，通过大量的生产线检测数据确定了一组电导率-时间曲线作为标准曲线，以此为依据可快速判断乳化炸药的储存期。
Abstract:
Demulsifier Tween80 was used to demulsify emulsion matrix or emulsion explosive in 400 mL aqueous solution at 70 ℃ and 400 r/min. Conductivity changes of the aqueous solution during demulsification were detected, an conductivity-time curves were drawn. The stability of emulsion matrix or emulsion explosive during storage could be determined. By analyzing experimental principle and factors affecting the experiment, change rules of the conductivity of emulsion matrix or emulsion explosive with time under natural storage and freezing conditions were obtained. The detection results of conductivity method are basically consistent with the crystallization and demulsification state and bursting performance observed by microscope. Finally, according to a large number of production line test data, a conductivity-time curve was determined as the standard curve. Based on this, the storage period of emulsion explosives can be quickly determined.
