ABSTRACT

Encapsulation is proposed as a safer way of handling energetic materials. Different encapsulation methods for explosives, such as solvent evaporation, spray coating and supercritical carbon dioxide assisted encapsulation, were explored. Explosive training aids, where energetic materials, such as triacetone triperoxide (TATP), erythritol tetranitrate (ETN) and trinitrotoluene (TNT), are encapsulated in a polymer matrix were developed, followed by comprehensive quality control testing, including differential scanning calorimetry (DSC), thermogravimetric analysis-infrared spectroscopy (TGA-IR), gas chromatography-mass spectrometry (GC-MS), high-resolution mass spectrometry (HRMS) and sensitivity testing, and finally field approved by canine units trained on the pure explosive.

摘要

封装被提议作为处理高能材料的更安全的方式。探索了不同的炸药包封方法，如溶剂蒸发、喷涂和超临界二氧化碳辅助包封。开发了将三过氧化三丙酮 (TATP)、四硝酸赤藓糖醇 (ETN) 和三硝基甲苯 (TNT) 等高能材料封装在聚合物基质中的爆炸训练辅助设备，然后进行了全面的质量控制测试，包括差示扫描量热法 (DSC) , 热重分析-红外光谱 (TGA-IR), 气相色谱-质谱 (GC-MS), 高分辨率质谱 (HRMS) 和灵敏度测试, 最后经过纯炸药训练的犬类单位的现场批准。
