DETONATING COMBINATION, RELAY FOR DETONATOR COMPRISING SUCH DETONATING COMBINATION AND DETONATOR COMPRISING SUCH RELAY

摘要

Detonating combination, relay for detonator comprising such a detonating combination and detonator comprising such a relay The present invention relates to a detonating combination intended to be placed within a detonator. This explosive combination includes two compositions including: a) a first composition comprising at least one thermite and at least one explosive, said at least one thermite comprising particles of nanometer, submicrometer, micrometer or submillimeter size, or mixtures thereof; said first composition further comprising solid microspheres of micrometric or submillimetric size, or mixtures thereof when said at least one thermite consists essentially of particles of nanometric or submicrometric size, or mixtures thereof; said at least one explosive comprising particles of nanometer or submicrometer size, or mixtures thereof; said first composition having a porosity of between 30% and 70%, preferably between 35% and 65%, and b) a second composition comprising at least one explosive comprising particles of nanometric, submicrometric, micrometric or submillimetric size, or mixtures thereof. The invention also relates to a relay comprising such a detonating combination, as well as a detonator comprising such a relay.
