PETN和RDX在无起爆药雷管中作为激发药的对比性研究

为了探讨激发药对无起爆药雷管延期时间的影响,通过对比PETN和RDX分别作为激发药引起无起爆药雷管延期时间的差异,根据热点起爆理论对数据进行分析.结果表明,对于无起爆药瞬发电雷管,PETN和造粒RDX均可作为激发药,但PETN的延期时间(8.33ms)小于造粒RDX(9.35ms)；对于无起爆药非电延期雷管,造粒RDX作为激发药时延期时间稳定,雷管起爆可靠；PETN可作为无起爆药瞬发非电雷管或低段别(12～13段)非电延期雷管的激发药.

Research on the Performance of PETN and RDX as the Excitation Powder

The difference of the delay time of non-primary detonator was compared by using PETN and RDX as the excitation powder, and the data were analyzed based on hot spot initiation theory. The results show that in non-primary instantaneous electric detonator, PETN and granulated RDX can be used as the excitation powder, but the delay-time of PETN (8.33 ms) is shorter than that of granulated RDX (9.35 ms), in non-primary non-electric delay detonator, the delay-time of the granulated RDX as the powder is steady; PETN can be used as the excitation powder in instantaneous or lower non-primary non-electric delayed detonator.
