微型爆炸网络用DNTF/HMX基传爆药研究
Research on the DNTF/HMX Based Booster Explosive Employed in the Microscale Explosion Network
摘要
Abstract
In order to make the explosive charged in explosion network meet the charge uniformity, low detonation velocity dispersion requirement and at the same time achieve the high detonation velocity, high security, explosion detonation in groove of small size, 3,4-dinitrofurazanfuro xan(DNTF) and HMX were chosen as the main explosive, GAP as the binder polymer, together with the other additives.A kind of booster formula was successful designed suitable for network booster and it was charged into the explosion network of microsize.The particle size and morphology of the DNTF and HMX was characterized by scanning electron microscopy (SEM).X-ray diffraction (XRD) was utilized to test the crystal.The booster charging surface were tested and observed by SEM and the detonation performance, impact sensitivity, shock sensitivity and detonation velocity were tested afterwards.The results showed that when the solid content was of 85%, the viscosity of the booster slurry can meet the requirements of charging process.After curing process the surface of booster was smooth with uniform particle distribution.The crystal of the two kinds of explosives was not changed and the density of booster charging in the groove was up to more than 1.6 g·cm-3 (92% of theoretical density).Under this density of booster charging, the critical dimension of linear detonation is 0.6 mm×0.6 mm, the detonation velocity in 0.8 mm×0.8 mm groove was 7558 m·s-1 and the velocity range was 29 m·s-1.The impact sensitivity of the DNTF/HMX based booster explosive characteristic height (H50) was 45.2 cm (5.0 kg hammer), the thickness of small scale gap was 8.74 mm in the shock sensitivity test.关键词
