Abstract:To explore the storage properties of the emulsion explosive after pressed by shockwave,the explosion shock wave of the emulsion explosive was tested at a period after it was pressed by shockwave in water,and the storage properties were compared and judged with its explosion shockwave crest values. The results show that there is no obvious decline of the explosion shockwave crest values in a certain period after pressed by the outside shockwave,but the explosive capacity will be worsen quickly after this period and lose the priming sensitivity by cap. The period of keeping the cap sensitivity may be several minutes,some days or even several weeks,which is related to the intensity of the pressing shockwave,the emulsifying agent,the sensitizer etc. The relationship is that the period will be shorter with the increasing of the shockwave intensity,and it will increase with the increasing of emulsifying agent content,and when the emulsion explosive is pressed by the shockwave with 108 MPa peak pressure,the period of keeping cap sensitivity declines from over 18 h to less 1 h with the increasing in the mass percent of the hollow glass microballoon from 2% to 5%,and with the increasing of the mass percent of the expanded perlite from 2% to 5%,the period declines from 24 min to several minutes.
