摘要:
为获得高威力且热稳定性良好的乳化炸药，研制了一种含有TiH2的乳化炸药，并对该乳化炸药的性能进行测定。爆速、爆热和猛度实验研究发现，加入TiH2会使乳化炸药爆速微降，同时提升其爆热和猛度。当乳化炸药中TiH2质量分数为2%、4%时，爆热分别增加了4.21%、5.66%；猛度分别增加了15.29%、17.20%。TG-DTG实验研究发现，加入TiH2不会影响乳胶基质的热分解过程，但会降低其表观活化能。当乳化炸药中TiH2的质量分数为2%、4%时，乳化基质的表观活化能分别降低了21.04%、12.61%。TiH2能够在不影响乳化基质热分解过程的同时，提高乳化炸药威力。
Abstract:
In order to obtain the emulsion explosive with high power and good thermal stability, an emulsion explosive containing TiH2 was developed, and its properties were measured. Through the experimental study on detonation velocity, detonation heat and brisance, it is found that the addition of TiH2 will slightly reduce the detonation velocity of emulsion explosive while improving its detonation heat and brisance. When the mass fraction of TiH2 in the emulsion explosive is 2% and 4%, the detonation heat increases by 4.21% and 5.66%, and the brisance increases by 15.29% and 17.20%, respectively. TG-DTG experiment shows that the addition of TiH2 will not affect the thermal decomposition process of the emulsion matrix, but will reduce its apparent activation energy. When the mass fraction of TiH2 in the emulsion explosive is 2 % and 4 %, the apparent activation energy of the emulsion matrix decreases by 21.04% and 12.61%, respectively. The addition of TiH2 can improve the power of emulsion explosive without affecting the thermal decomposition process.
