硼含量对含铝炸药水下爆炸能量的影响

将铝硼混合添加到含铝炸药(配方体系为Al/B/AP/RDX/wax)中,采用水下爆炸法,研究硼含量对含铝炸药水下爆炸能量的影响。结果表明,水下爆炸中,随着硼含量的增加,炸药的冲击波能降低,气泡能先增加、后逐渐减小;当硼质量分数为10%时,炸药水下爆炸总能量达到最大值5.942 MJ/kg,比含铝样品提高5%,其中气泡能为4.999 MJ/kg,比含铝样品提高7%,是TNT的2.2倍。在含铝炸药中添加少量的硼粉,可以提高炸药的水下爆炸能量水平。

Influence of Boron Content on Underwater Explosion Energy of Aluminized Explosive

Mixture of aluminum and boron was added to RDX-based explosives with the formulation of Al/B/AP/RDX/Binder, and underwater explosion were performed to study the influences of boron content in the mixture on the deto-nation energy of the explosives. The test results indicate that the shock wave energies decrease with the increase of boron content in underwater explosion, while the bubble energies increase firstly and then decrease. When the mass fraction of boron is 10%, the total energy of the explosive reachesa maximum of 5. 942 MJ/kg, which is 5% higher than the alumi-nized explosive. The bubble energy is 4. 999 MJ/kg, which is 2. 2 times of that of TNT, and 7% higher than that of the aluminized sample. Adding some boron powders to Al-B mixture can improve the underwater detonation energy of the alumi-nized explosive.
