Performance and Application Research of ANPyO /LLM-105 Mischcrystal and Its Moulding Powder

Performances and applications of ANPyO/LLM-105 mischcrystal and its molding powder were studied. ANPyO /LLM-105 mischcrystal was prepared by a recrystallization method using DMF as solvent. Structure and properties of ANPyO /LLM-105 mischcrystal were characterized by SEM,TG,vacuum stabilities and safety properties tests. The SEM test shows that ANPyO /LLM-105 mischcrystal has regular shape and smooth surface. The TG curve of ANPyO /LLM-105 mischcrystal is similar to that of ANPyO or LLM-105. In 48 h vacuum stability test at 200 ℃,outgassing quantity of mischcrystal is 0. 21 mL /g,impact sensitivity is 138 cm,friction sensitivity is 30%,and shock wave sensitivity is 7. 0 mm. Using F2311as binder,mischcrystal moulding powder was prepared by aqueous suspension method,and properties of the mischcrystal moulding powder were characterized by heat resistance,detonation velocity,initiation and penetration depth tests. The results show that the detonation velocity of moulding powder mixture explosive is 7 350 m /s( 1. 75 g /cm3). When the charge pressure is 5. 50 MPa and the charge density is 1. 77 g /cm3,it could be detonated stably by oilfield detonating cord,and the penetration depth is 142 mm × 10. 0 mm. Safety and explosion properties of ANPyO /LLM-105 mischcrystal and moulding powder are comparable with ANPyO,and their shock wave sensitivities are a little higher than that of ANPyO.
