目的研究高氮量单基火药吸收硝化甘油增能及钝感以后的物理、力学性能．方法通过压缩实验、落锤冲击实验、爆热实验等方法进行研究．结果高氮量单基火药增能后，其力学强度略有下降，但仍然远高于双基或三基火药；钝感层与基体火药的界面粘结强度明显提高．当吸收硝化甘油１４．１％时，表征能量的爆热提高约５．４％，在６５℃加速老化９０ｄ后，仍无脱粘现象发生．结论所研究的增能钝感火药能有效地增加能量，改善基体火药与钝感层的粘结强度，具有重要的工程应用价值．
Aim To study the physical and mechanical properties of high nitrogen single base powder for absorbing nitroglycerin after energization and desensitization. Methods Compression experiments, drop-hammer impact experiments, detonation experiments and other methods were carried out. Results The mechanical strength of the high-nitrogen mononuclear gunpowder decreases slightly after being energized, but it is still much higher than that of the birefringent or triple-base gunpowder. The interfacial bond strength between the base layer and the base gunpowder is obviously improved. When 14.1% of nitroglycerin was absorbed, the detonation of characterizing energy increased by about 5.4%. After accelerated aging at 65 ℃ for 90 days, no debonding occurred. Conclusions The energized insensitive gunpowder can effectively increase the energy and improve the bond strength between the matrix gunpowder and the insensitive layer, which has an important engineering application value.
