Description

technical field [0001] The invention relates to an energy-gathering explosive device, in particular to a combustion-to-detonation energy-gathering explosive device, which belongs to the technical field of explosive devices. Background technique [0002] In the traditional detonation method, the detonator is mainly used as the detonation material. But used detonator layer (as lead azide etc.) in detonator, its production and use process all can cause serious pollution to environment; Detonator is prone to explosion accident in production, storage, transportation process; And the use of detonator has One-time feature, if used in large-scale projects, the price is more expensive. In order to solve these problems, the predecessors designed a flyer-type non-priming detonator based on the principle of combustion to detonation. The detonator solves the pollution problem and safety problem of the priming charge of the traditional detonator, but its production price is expensive, a...
