摘要:
为了提高弹药的爆轰性能,该文提出通过改变单质炸药的颗粒形态来提高炸药的装药 性能。给出了重结晶法制备球形化RDX 颗粒的实验原理和流程,测试了球形化RDX 的晶体形 状、热性能和热感度,以及以球形化RDX 为基的熔铸炸药药柱密度。结果表明,与普通RDX 颗 粒相比,球形化RDX 颗粒表面光滑,内部缺陷显著减少,熔化峰温提高1. 57 ℃,分解峰温提高 3. 66 ℃; 5 s 爆发点提高1 ℃,安全性能有所提高; 球形化RDX60 /TNT40 和RDX75 /TNT25 熔铸 炸药的装药密度明显高于普通RDX60 /TNT40 和RDX75 /TNT25 熔铸炸药。
Abstract:
In order to improve the detonation property of ammunition, the method of changing the shape of single-component explosive particle is adopted. The recrystallization principle and process of spherical hexogeon( RDX) is introduced. The crystal shape, thermal property, thermal sensitivity of the spherical RDX and the density of melt-cast spherical RDX/TNT and ordinary RDX/TNT explosive are tested. The results show that,compared with the normal RDX, the spherical RDX has less crystal defects and sleek surface, its melt peak temperature and decomposition peak temperature are seperately 1. 57 ℃ and 3. 66 ℃ higher,and the 5 s ignition point is 1 ℃ higher. The stability of spherical RDX is improved,and the densities of melt-cast spherical RDX60 /TNT40 and RDX75 / TNT25 are higher than that of ordinary RDX60 /TNT40 and RDX75 /TNT25.
