摘要:
为了得到乙二胺?三乙烯二胺?高氯酸盐（SY）在电爆作用下的爆轰特性，以镍-铬(Ni-Cr)丝、铝(Al)丝和钨（W）丝作为等离子体源，进行了SY的等离子体起爆特性研究。在改变炸药密度、炸药粒度和添加组分进行包覆等条件下，得到相对应的起爆阈值；通过比较阈值大小以判断起爆难易程度。结果表明：炸药粒度较小或装药密度较大时，更容易起爆。等离子体起爆SY药柱时，SY粒度与装药密度相比，粒度大小对起爆难易的影响作用更大。当装药密度大、炸药粒度小时，由氟橡胶包覆的SY相对容易起爆。SY药柱对这几种金属桥丝等离子体感度由大到小的顺序为：Ni-Cr丝、W丝、Al丝。另外，药柱的中心孔径较小时更容易被起爆。
Abstract:
To study the detonation properties of SY under initiation of electric explosion, explosive bridge wires made by Ni-Cr, Al or W were used as energy conversion component to detonate SY columns. Different density, particle size, and addition of components of SY columns were tested to obtain corresponding thresholds of initiation voltage. The results show that larger density or smaller particle size is conducive to detonate. Comparing to density and particle size, the latter has a greater impact on the degree of difficulty. Under the conditions of large density and small particle, SY columns coated with fluororubber are the easiest to detonate by plasma. SY is more sensitive to the Ni-Cr plasma than to W plasma or Al plasma. In addition, small pores of the pillars are more likely to be detonated.
