| 摘 要： | 为评价RDX与Al粉末在滚筒混合过程中的静电火花感度,采用尖端放电方法,测定RDX、RDX-Al混合物的静电火花感度,采用斜槽法测量了RDX、RDX-Al混合物的摩擦产生静电积累量.研究表明:RDX的不发生爆炸的最大静电火花能量为0.013 J,RDX-Al不发生爆炸的最大静电火花能量大于0.013 J;在1 m不锈钢滑槽内滑行过程中,RDX静电积累值的最大值约为-3.0～-5.0 μ/kg,此时能产生的最大火花能量为1.41×10~(-3) J,都小于RDX的不发生爆炸的最大静电火花能量0.013 J,发生50%爆炸所需的静电火花能量为0.288 J,发生100%爆炸所需的最小静电火花能量为0.577 J;RDX-Al静电积累量的最大值为1.20μC/kg,静电积累产生的电火花能量,不能直接引燃RDX-Al炸药粉末;加入3%～8%的石油醚和乙酸乙酯后,RDX-Al炸药静电积累值的最大值为1.50μC/kg,其可能产生的火花能量为1.23×10~(-4) J,此能量也小于石油醚和乙酸乙酯的最小点火能.

| Abstract: | For estimating electrostatic spark sensitivity of RDX-Al powder in the process of roller mixing,advanced charge method was taken to measure electrostatic spark sensitivities of RDX and RDX-Al,and chute method was applied to measuring electrostatic accumulations of RDX and RDX-Al in the friction condition.The investigated results show that the max electrostatic energy of RDX is 0.013 J, and that of RDX-Al is greater than 0.013 J at inexplosive condition;slipping in 1 m chute,the maxmum electrostatic accumula... |
