Abstract

The invention discloses a miniaturized insensitiveness detonating tube detonator. The miniaturized insensitiveness detonating tube detonator includes a detonating tube 1, a bayonet plug 2, a tube shell 3, a silk pad 4, ignition powder 5, a cover cap 6, an inner tube 7, intermediate powder 8, bottom powder 9 and a bottom cap 10. Boron/ nitrate of potash is pressed into the cover cap sticky with thesilk pad, and hexanitrostilbene is loaded into the inner tube and the bottom cap; the explosive hexanitrostilbene is adopted to replace initiating explosive, the combination structure of the cover cap, the inner tube and the bottom cap is used in a matched mode during powder loading, the axial size of the detonator is reduced, the radial constraint of the powder loading is strengthened, and the burning turning to detonation of the insensitive powder loading is effectively achieved; and the detonator is high in safety and simple in process structure, and can meet the miniaturization requirements of the detonation structure.

Description

technical field [0001] The invention relates to the technical field of engineering detonation, in particular to a miniaturized insensitive nonel detonator. Background technique [0002] With the continuous advancement of human science and technology, modern industry has more and more in-depth knowledge of blasting equipment, and thus has higher and higher performance requirements for detonating devices. The improvement and innovation research of detonation technology mainly starts from two aspects, namely the precise delay of detonation and safety performance, and the ideas used have gradually changed from traditional single structure to complex structure. Due to the high sensitivity of the primary explosive in the traditional detonator, it is easy to ignite once it is impacted by the outside world, so extra care must be taken during transportation, storage and use. At the same time, a large amount of waste water is often produced in the production process, and because of i...
