RDX/aluminum composites were prepared by the spray-drying method with F₂₆₀₂ as a binder. The morphology and covering effect of composites were characterized by scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). The effect of the processing parameters on the morphology of the samples was investigated. The impact sensitivity and thermal decomposition behavior of RDX/aluminum composites were also measured and analyzed. Optimal morphology of samples was achieved when the inlet temperature, nitrogen flow rate, and suspension feed flow rates were 80°C, 473 L·h^-1, and 4.5 mL·min^-1, respectively. In addition, RDX/aluminum composites with the same content were prepared by a coverage-mixing method for comparative analysis. Experimental results showed that the thermal sensitivity and the impact sensitivity of RDX/aluminum composites prepared by the spray-drying method were significantly lower than those of RDX/aluminum composites prepared by the coverage-mixing method.

喷雾干燥法制备RDX /铝复合材料的性能

用F ₂₆₀₂作为粘合剂通过喷雾干燥法制备RDX /铝复合材料。通过扫描电子显微镜（SEM）和X射线光电子能谱（XPS）表征了复合材料的形貌和覆盖效果。研究了加工参数对样品形态的影响。还测量和分析了RDX /铝复合材料的冲击敏感性和热分解行为。当入口温度，氮气流速和悬浮液进料流速分别为80°C，473 L·h ^-1和4.5 mL·min ^-1时，样品的形态最佳。， 分别。另外，通过覆盖混合法制备具有相同含量的RDX /铝复合材料以进行比较分析。实验结果表明，喷雾干燥法制备的RDX /铝复合材料的热敏性和冲击敏感性明显低于覆盖-混合法制备的RDX /铝复合材料的热敏性和冲击敏感性。
