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-A1混合物的静电火花感度，采用斜槽法测量了RDX、RDX-A1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-A1不发生爆炸的最大静电火花能量大于0.013 J；在1m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 μC/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瞥电积累量的最大值为1.20 μC/kg，静电积累产生的电火花能量，不能直接引燃RDX-A1炸药粉末；加入3%～8%的石油醚和乙酸乙酯后，RDX-A1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 mix?ing, 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-A1 in the friction condition. The investigated results show that the max electrostatic energy of RDX is 0.013 J, and that of RDX-A1 is greater than 0.013 J at inexplosive condition; slipping in 1 m chute, the max-mum electrostatic accumulation of RDX is about - 3.0 -- 5.0 μC/kg, and max electrostatic energy is 1.41 X 10-3 J, which is less than E0 0.013 J, E50 0.288 J and E_ 0.577 J of RDX; the maxmum elec-trostatic accumulation of RDX-A1 is 1.2 μC/kg，by which the produced energy can not directly fire RDX-A1 explosive powder; after adding 3 % ?8 % petroleum ether and ethyl acetate, the maxmum electrostatic accumulation of RDX-A1 explosive is 1.50 μC/kg, which produces probably 1.23 X 10 —4 J spark energy, that is less than minmum ignition energy of petroleum ether and ethyl acetate.
