摘要
含能材料的球形化可以显著提升炸药晶体的加工及应用性能。基于目前国内外对典型含能材料球形化技术的相关研究,从结晶策略角度综述了球形单晶体、球形聚结晶体以及球形分支晶体的研究进展。重点介绍了各球形产品的结晶工艺、球形化机理及降感效果。指出球形产品具有流动性好、堆密度高、感度低的特点,应用潜力巨大,建议结合晶体工程思维,建立各典型含能材料结晶基础数据库、强化在线过程监测、完善模型计算以及多学科交叉研究,为含能材料球形化结晶工艺精确调控和工业生产提供指导。
The spheroidization of energetic materials can significantly improve the processing and application properties of explosive crystals.Based on the current research on spheroidization technology of typical energetic materials both in China and abroad,the research progress of spherical single crystals,spherical agglomerates and spherical branched crystals are reviewed from the perspective of crystallization strategy.The crystallization process,spheroidization mechanism and desensitization effect of spherical products are emphatically introduced.It is showed that spherical products have the virtues of good flowability,high bulk density and low sensitivity,and have great potential in explosive applications.Combining crystal engineering thinking,it is suggested to construct the crystallization database of typical energetic materials,strengthen online process monitoring,improve model calculations and multidisciplinary cross study,thus providing guidance for precise regulation and industrial production of spherical crystallization process of energetic materials.
