本文介绍了高光敏炸药需要解决的四个问题,并用Nd激光器(脉冲宽度25ns)测定了三种过渡金属配位化合物压制药住的临界起爆能,其中高氯酸·3(5)-氨基-4-肼基-1,2,4-三唑合铜(Ⅰ)药柱的起爆阈值约为40mJ/cm ̄2,比叠氮化铅药柱的小约10倍;还测定了高氯酸·5-肼-四唑合汞(Ⅱ)与透明的聚合物粘结制成的药片的临界起爆能E_c,所得结果:聚合物含量在10~30%范围内,E_c值逐渐缓慢降低;当超过30%时E_c,值急剧升高。对配位化合物(Ⅰ)言,当聚合物含量为10%时,E_c值随药片中炸药含量(mg/cm ̄2)的增加而明显下降。结论认为这类过渡金属的配位化合物是对激光敏感的新型炸药;还提到这样的现象:厚药片与单质药片比,其起爆阈值较低,而薄药片则起爆阈值较高,从而表明药片有临界厚度的问题,即当药片薄于临界厚度,即使用于厚药片所需起爆能的15倍,也不能被起爆,因此认为可能存在激光能在炸药内部产生定域(Localization)机理。
In this paper, four problems to be solved for high photoluminescent explosives are introduced. The critical detonation energies of three transition metal coordination compounds are determined by Nd laser (pulse width 25 ns), among which perchloric acid · 3 (5) The initiation threshold of 4-hydrazino-1,2,4-triazole copper (Ⅰ) was about 40mJ / cm ~ 2, which was about 10 times smaller than that of lead azide. The perchloric acid The critical initiation energy E_c of tablets prepared by bonding of 5-hydrazine-tetrazolium-mercury (II) and transparent polymer was as follows: the content of E_c gradually decreased when the content of polymer was in the range of 10 ~ 30% E_c exceeds 30%, the value rises sharply. For the coordination compound (Ⅰ), when the polymer content is 10%, the value of E_c decreases obviously with the increase of explosive content (mg / cm ~ 2) in the tablets. It is concluded that such transition metal complex compounds are laser-sensitive new explosives; mention is also made of the phenomenon that thicker tablets have a lower detonation threshold than simplex tablets and thin tablets have a higher detonation threshold, indicating that tablets There is the problem of critical thickness, ie when the tablet is thinner than the critical thickness, it can not be detonated even 15 times as much as the detonating energy required for a thick tablet, and therefore it is thought that there may be a laser localization mechanism inside the explosive.
