Abstract:

The aging degree of emulsion explosive matrix (EEM), as the principal component in emulsion explosives (EE), has a significant impact on operational performance of EE. By analyzing aging mechanism of EEM, an aging equation was derived from the kinetic of crystallization. The equation was validated by previous experimental data. The results indicate that it fits well judging by the adjusted goodness-of-fit statistic. The characteristic time in the aging equation characterizes the time required for the EEM to reach amaximum in an external environment. It is a quantification of EEM stability, which is conducive to evaluate the storage performance of different products under the same aging condition.

Key words: aging, emulsion explosive, emulsion explosive matrix, stability, crystallization

摘要:

乳胶基质作为乳化炸药的主体材料,其储存过程中的老化程度关系着产品的使用性能。通过分析乳胶基质的老化机理,从结晶动力学角度对其老化规律进行研究,得到了乳胶基质的老化方程。采用实验数据对老化方程进行验证,结果表明该方程具有很好的拟合优度。老化方程中的特征时间表征了在某种外界环境下,乳胶基质老化速率达到最大值时所需要的时间,是对乳胶基质稳定性的一种量化,有助于评判相似老化条件下,不同产品的储存性能。
