Abstract

The invention discloses an allochroic detonating tube with high detonation sensitivity. The detonating tube includes a tube body and detonating drug, wherein the detonating drug includes the following components in parts by weight: 90-95 parts of cyclotrimethylene trinitramine, 7-10 parts of A1 powder and 15-20 parts of an active alterant; the active alterant is laminar ultra-fine aluminum powder; cyclotrimethylene trinitramine is short cylindrical particles with a plurality of corner angles and produced by adopting a wet process fluid energy milling technology, and the particle size distribution is uniform. According to the invention, the laminar ultra-fine aluminum powder is added into the detonating drug formula and served as the active alterant; the color of the product before detonation is silver gray and becomes dark after detonation, therefore, the visual effect is remarkable, which facilitates the check of the detonating network after detonation and the judgment on whether the detonation is normal or not, the detonation sensitivity and detonation reliability of the detonating tube are greatly improved; cyclotrimethylene trinitramine in the detonating drug formula adopts a short cylindrical shape with a plurality of corner angles, and the particle size distribution is uniform, therefore, the detonation reliability of the detonating tube is improved.

Description

technical field [0001] The invention relates to a color-changing nonel with high detonation sensitivity Background technique [0002] The sensitivity of the detonator guides the degree of difficulty for the detonator to be detonated under the action of external excitation impulse (excitation impulse energy). According to the different modes of action of the exciting impulse energy acting on the nonel, the sensitivity of the nonel is divided into axial sensitivity and lateral sensitivity. The sensitivity of the detonator is its main performance index, so increasing the sensitivity of the detonator has been a research issue for this year. In practical application, the sensitivity of the detonator should neither be too low nor the higher the better, and must fall within a moderate range. In order to check whether the detonation is normal after the detonation, adding a color-changing agent to the nonel has become a current hot spot. But the plastic nonel that has added discol...
