摘要:
利用水悬浮法将氟橡胶包覆在硝酸肼镍(NHN)表面制备出了NHN造型粉,并将其应用于基础雷管。通过DSC研究了NHN造型粉的热性能，测试了NHN造型粉的机械感度和火焰感度以及工业基础雷管的撞击感度和起爆能力。研究结果表明：氟橡胶包覆能够提高NHN的热稳定性，且热稳定性随着氟橡胶包覆量的增加而提高；NHN造型粉的机械感度均低于原料NHN，当氟橡胶包覆量（质量分数）为9%时，撞击感度下降幅度明显，可达142.9%；NHN造型粉用在基础雷管中做起爆药，可以降低基础雷管的撞击感度并保持其起爆能力。
Abstract:
Nickel hydrazine nitrate (NHN) molding powder, coating fluororubber on NHN surface, was prepared by water suspension method and applied in basic detonators. Thermal properties of molding powder were measured by DSC. Mechanical sensitivity and flame sensitivity of molding powder, as well as the impact sensitivity and initiation ability of basic detonators were tested. The results show that of NHN coated with fluorinerubber has enhanced thermal stability, which increases with the increasing of the fluorinerubber. Besides, the mechanical sensitivity of NHN molding powder is lower than that of raw NHN, and the impact sensitivity decreases by 142.9% when the mass fraction of fluorinerubber is 9%. Furthermore, NHN molding powder used as the primary explosive in detonator will reduce impact sensitivity and maintain initiation ability of basic detonator.
