What is a detonating tube?

Detonating tube diameter 1.5mm, an outer diameter of 3mm, an inner wall coated with a thin layer of explosive HMX and aluminum powder and other additives, is coated with about 20mg per meter, when given the appropriate initiation energy, a thin layer of the inner wall of explosives will be It is blasted at a speed of 1900 to 2000 m/s. The detonating tube itself has no explosive properties and will not explode due to vibration, shock, friction and flame. During the explosion of the detonating tube, only the tube flash can be seen, and the tube body will not be broken. See Figure 1.

The detonating tube has good electrical resistance, explosion resistance, impact resistance and water resistance. The detonating tube performance is stable and good. It is possible to detonate a kilometer at a time without having to have an indirect force. Even in the middle of the detonating tube, any kinking, drawing deformation, and folding, etc., do not affect the normal explosion. The detonating tube itself cannot directly detonate general industrial explosives.
