真空蒸镀炸药为爆炸网络提供了一种小尺寸装药技术。探究炸药成膜机理对研究薄膜炸药的爆轰性能有重要意义。本文以太安作为被蒸镀材料 ,在实验室条件下进行热蒸发 ,得到太安薄膜。对其进行红外光谱分析 ,并用扫描电镜观察其表面形貌。通过对薄膜分子结构和分子间作用力的分析 ,并结合前人的研究成果 ,推断出太安薄膜是岛状生长形成的多晶薄膜。 Vacuum evaporation of explosives for the explosive network provides a small-size charge technology. Exploring the mechanism of explosive film formation is of great significance for studying the detonation performance of film explosive. In this paper, Tai’an as the material being evaporated, thermal evaporation under laboratory conditions, Tai’an film. The infrared spectrum analysis was carried out and the surface morphology was observed by scanning electron microscopy. Through the analysis of the molecular structure of the film and the intermolecular force, combined with the previous research results, it is concluded that the polyanion film formed by island-like growth is Tai’an film.
