ABSTRACT

On 15 high nitrogen and three polynitrated polyazaarenes (including six azido-derivatives), the paper demonstrates the relations between their impact sensitivities (Edr) on the one hand and the volume heats (ρQmax) or a representative of detonation pressure (ρD2) of their explosion or their enthalpies of formation (ΔHform) on the other. The semi-logarithmic subrelations between the Edr and ρQmax values are limited by the mechanism of primary fission. While the mentioned relations between Edr and ρQmax values for azido derivatives predominantly show the expected course, in the case of the remaining high-nitrogen EMs, the opposite is the case, i.e., an increase in ρQmax values corresponds to a decrease in impact sensitivity. The same is valid for ρD2 values as an independent variable. Taking the energy content of the studied EM molecules, represented by ΔHform values, instead of the heat of explosion, yields unambiguous semilogarithmic relations, according to which the growth of the ΔHform values increases impact sensitivity. The results obtained indicate that it is necessary to distinguish between the influences of the performance and the energetic content of high-nitrogen energetic materials on their initiation reactivity.

能量含量及其输出对高氮含能材料冲击敏感性的影响

摘要

对 15 种高氮和 3 种多硝化聚氮杂芳烃(包括 6 种叠氮衍生物),本文论证了它们的冲击敏感性(E dr)一方面与体积热(ρQ max)或代表爆轰压力(ρD 2 ) 它们的爆炸或它们的形成焓 ( ΔH形式) 在另一个上。E drρQ最大值之间的半对数子关系受到初级裂变机制的限制。虽然E drρQ max之间的关系叠氮基衍生物的值主要显示预期的过程,在剩余的高氮 EM 的情况下,情况正好相反,即ρQ最大值的增加对应于冲击灵敏度的降低。这同样适用于作为自变量的ρD 2值。取所研究的 EM 分子的能量含量,以ΔH形式值表示,而不是爆炸热,产生明确的半对数关系,根据该关系,ΔH形式的增长值会增加影响敏感性。所得结果表明,有必要区分高氮含能材料的性能和含能量对其引发反应性的影响。
