不同溶剂中黑索今的结晶与其力学性质分析

Analysis of Mechanical Properties of RDX Crystals Obtained from Different Solvents

制备了三种黑索今晶体,第一种是由直接法制得的,其它两种是分别将第一种产品在丙酮和环己酮溶剂中重结晶得到的。试验并分析了这三种黑索今的机械性能。其中,环己酮重结晶黑索今具有最好的机械性能。数据对黑索今的应用具有一定意义。

Three types of RDX crystals were prepared. The first one was obtained from the direct production process, and the other two were recrystallized from the first one in acetone and in cyclohexanone respectively. The mechanical performances of these three RDX crystals were tested and analyzed. Among them, the one recrystallized from cyclohexanone possesses the best mechanical performances. The pressed charge column of this kind of RDX crystal did not appear breakage until the pressure was brought to (383 MPa). Besides, the crystal from cyclohexanone exhibits a smoother surface, a better transparency, and a more regular shape in comparison with others. A number of experimental results related to different RDX crystals are presented in this paper, which would be useful for RDX′s molding application.
