为了研究超细与复合途径对炸药性质的影响 ,运用 YL G型高效研磨机制备出 RDX/Al超细复合粒子 ,并以水和乙醇作研磨介质进行了比较研究 ,并对复合粒子粒度、粒子形貌、热力学性能、粒子组分及爆热等进行了较全面的研究。结果表明 :在水中研磨有助于粒子的复合 ,而在乙醇中研磨则有利于粒子的超细化和分散。在乙醇中研磨样品由于高能物质 (C2 H5O) 3Al的生成 ,其爆热提高明显。为了解释这些现象 ,提出了超细复合模型及超细 RDX/Al复合炸药热分解模型 ,其结论与实验结果相符合。
In order to study the influence of ultrafine and complex route on the properties of explosives, the RDX / Al composite particles were prepared by YL G high efficiency mill and compared with water and ethanol as grinding media. The particle size, Morphology, thermodynamic properties, particle composition and explosion heat conducted a more comprehensive study. The results show that: grinding in water helps to compound the particles, while grinding in ethanol is conducive to the ultrafine particles and dispersion. Grinding samples in ethanol due to the generation of high-energy material (C2 H5O) 3Al, the burst heat increased significantly. In order to explain these phenomena, the ultrafine composite model and the thermal decomposition model of ultrafine RDX / Al composite explosives are proposed. The conclusions are consistent with the experimental results.
