摘要
Abstract
The RDX-based aluminized explosives with different contents of 3-nitro-1,2,4-triazol-5-one(NTO)were prepared.The sensitivities and detonation velocity of the RDX-based aluminized explosives were tested by the explo-sion probability method and the electrometric methods.Effect of the NTO content on the mechanical sensitivities and detonation velocity of RDX-based aluminized explosive was studied.The results show that with increasing the NTO content,the mechanical sensitivities of aluminized explosive decrease obviously,the impact sensitivity decreased from 34% to 2%,the friction sensitivity decreased from 30% to 2%;the detonation velocity decreases with increas-ing the NTO content at the same density.When the mass fraction of NTO is 35%,the detonation velocity decreased to 7 764 m/s,which decreased by 169 m/s compared with the RDX-based aluminized explosive without NTO.关键词
