用弹簧探针法测试含硼铝炸药的爆轰性能
Detonation Property Measurement of Explosive Containing B /Al by Spring Electric Pin Method
摘要
Abstract
To explore the application of B /Al compound powder in thermosetting plastic bonded explosive ,six kinds of HMX based explosives containing boron (B) and aluminum (Al) were designed and prepared by adding oxidizer ammonium perchlorate (AP) ,B/Al compound powder and binder hydroxyl-terminated polybutadiene (HTPB) .Three kinds of Φ50mm explosive cylinders containing B /Al with shell and without shell were prepared respectively .The spring electric pin method was applied to measure detonation velocities of explosive cylinders with shell and without shell respectively .The detonation pressures were calculated by the experienced formula and relative dent depth method respectively ,the influence of B/Al compound powder content on detonation property was discussed .The results show that the explosives GH-4 ,GH-5 ,GH-6 are solidified by manual casting ,the densities of Φ50 mm explosive cylinders are between 1 .530 -1 .570 g/cm3 ,the deto-nation velocities are between 6 .900 - 7 .400 mm/μs ,and the detonation pressures are about 19 GPa ,the manual casting is suitable for screening of explosive formulas ;While the explosives PF-1 ,PF-2 and PF-3 are solidified by void vibration cast-ing ,the densities of Φ50 mm explosive cylinders are about 1 .693 g/cm3 ,the detonation velocities are between 7 .800 -8 .000 mm/μs ,and the detonation pressures are about 24 GPa .The explosive PF-3 with B/Al compound powder mass ratio of 1 : 1 and mass fraction of 20% ,the combination effect of metalized explosive leads a little of B /Al compound powder to take reaction in reaction area ,comparing to other formulas ,the detonation velocity and detonation pressure of explosive are higher .It indicates that the spring electric pin method can be an additional method for detonation velocity measurement ,and it can be adopted if copper foil electric pin method can′t be taken .关键词
