| 简介 |
The strand-shaped ignition means for non-electrical ignition of a detonator, comprises a tube-like casing (1) having a multi-layer structure, an explosive brought into the casing and a sealing element (2) formed at a final section of the ignition means. The sealing element encasing the casing has a cross section profile modifying itself over its length and a wave profile in the profile. The cross section of the sealing element is enlarged in a distance of the front surface of the final section in flange-like manner. The casing is completely filled with the explosive.
