【摘要】 防治B炸药渗油、抑制其药柱尺寸不可逆长大、增强其力学性能和降低感度是B炸药改性研究的重要内容。本课题采用一种芳香共聚物包覆RDX制作了一种改性B炸药。检测结果表明,B炸药经过改性后,渗油率降低了47.6％,强度提高了2倍,尺寸长大率降低了75％,感度也有所降低。更多还原

【Abstract】 It is mainly concerned the modification of Composition B to control exudation, restrain irreversible size growth, enhance mechanical properties and decrease sensitivity. A kind of modified Composition B was made with coated RDX by a kind of aromatic copolymer in this work. Experimental results show that the exudation percentage and the size growth percentage of modified Composition B could be decreased by 47. 6% and 75% respectively,and in the mean time,the mechanical intensity could be increased by 2 times. The sensitivity could be decreased to a certain degree, compared to that of Composition B without modification.更多还原
