摘要
为了提高传统乳化炸药的爆炸威力,研制了一种贮氢玻璃微球敏化的乳化炸药。利用水下爆炸试验和猛度测试试验,研究了添加不同含量的贮氢玻璃微球的乳化炸药的爆轰性能。理论计算得到了炸药猛度的比冲量。结果表明,与普通玻璃微球乳化炸药相比,贮氢玻璃微球含量为4%的乳化炸药的冲击波超压峰值、比冲击波能、比气泡能、总能量分别提升了14.25%、14.22%、11.11%、12.67%,猛度(铅铸压缩量)提高了3.03 mm,且随着贮氢玻璃微球的含量的增加,炸药的冲击波参数逐渐降低。贮氢玻璃微球在乳化炸药中起到敏化剂与含能材料的双重作用,因此贮氢玻璃微球敏化乳化炸药的作功能力与猛度得到显著提高。
To improve the explosion power of traditional emulsion explosives,a kind of emulsion explosive sensized by hydrogen storage glass microspheres was developed. The detonation performances of emulsion explosives with different contents of hydrogen storage glass microspheres were studied by underwater explosion test and brisance test. The specific impulse of explosive brisance was obtained by theoretical calculation. Results show that compared with emulsion explosives with ordinary glass microspheres,the shock wave overpressure peak,shock wave specific energy,bubble specific energy,total energy of the emulsion explosives with 4% hydrogen storage glass microspheres increase by 14.25%,14.22%,11.11% and 12.67%,respectively,and its brisance( lead cylinder compression value) increases by 3. 03 mm. The shock wave parameters of explosive decrease gradually with increasing the content of hydrogen storage microspheres. The hydrogen storage glass microspheres play a dual role of sensitizer and energetic material in the emulsion explosive. Therefore,a significant increase in the work capacity and brisance of the emulsion explosives sensitized by hydrogen storage glass microspheres is obtained.
