INITIATING ELEMENT FOR NON-PRIMARY EXPLOSIVE DETONATORS

摘要

An initiating element of non-primary explosive type comp-rising a confinement containing secondary explosive, having afirst end adapted for ignition of the secondary explosive byigniting means, optionally via delay and flame-conducting py-rotechnic compositions, a second end adapted for delivering adetonation impuls and a intermediate portion in which the se-condary explosive upon ignition is able to undergo a deflagra-tion to detonation transition. At least a part of the seconda-ry explosive is modified to give increased reaction rates atlow pressures.
