摘要
为了实现CA/CL-20点火起爆序列的微型化制备,基于喷墨打印技术,以叠氮化钠墨水、铜盐墨水、CL-20墨水为前驱体,采用分层打印的方式在SCB上原位制备了叠氮化铜(CA)和CL-20炸药,制成SCB+CA+CL-20微型化点火起爆序列,并通过发火性能试验及RDX雷管-铅板起爆试验对其性能进行了研究。结果表明:原位制备的CA在作用过程中发生了爆燃转爆轰,且能够点燃CL-20;SCB+CA+CL-20样品的点火持续时间超过6ms,而SCB裸桥和SCB+CA样品均小于2ms,表明打印的CL-20未发生爆轰,而是以燃烧为主;SCB+CA+CL-20点火起爆序列能够可靠起爆RDX雷管,并将铅板炸穿。
In order to achieve the miniaturization preparation of CA/CL-20 ignition and initiation sequences,based on inkjet printing technology,sodium azide ink,copper salt ink,and CL-20 ink were used as precursors to prepare copper azide(CA)and CL-20 explosives in situ on SCB through layered printing,resulting in the SCB+CA+CL-20 miniaturized ignition and initiation sequences,and its performance was studied through ignition performance test and RDX detonator-lead plate detonation test.The results show that the CA prepared in situ undergoes deflagration to detonation transition during the reaction process,and can ignite the CL-20;The ignition duration of the SCB+CA+CL-20 sample is more than 6 ms,while those of the SCB bare bridge and SCB+CA samples are both less than 2 ms,indicating that the printed CL-20 did not undergo detonation,but mainly burned;The SCB+CA+CL-20 ignition and initiation sequence can reliably initiate the RDX detonator and penetrate the lead plate.
