According to the way of detonation, detonators can be divided into the flame detonator, electric detonator, detonating cord detonator, and electronic (digital) Detonating cord (also called detonation cord, detacord, detcord, or primer cord) is a thin, flexible plastic tube usually filled with pentaerythritol tetranitrate (PETN, pentrite). With the PETN exploding at a rate of approximately 6,400 m/s (21,000 ft/s), any common length of detonation cord appears to explode instantaneously. It is a high-speed fuse which explodes, rather than burns, and is suitable for detDetonating cord

Explosive Manufacturing, Ingredients, Gunpowder Britannica

Explosive Manufacturing, Ingredients, Gunpowder: Manufacture of black powder was accomplished originally by hand methods. Ingredients were ground together with a mortar and pestle. The next step was to use crushing devices of wood (wooden stamps), also operated by hand, in wooden or stone bowls. The stamping process was gradually Abstract: A device for cutting a detonating cord having an explosive core is provided. The device includes a detonating cord holding member having a cord holding portion, such as an aperture or recess, configured to closely receive the detonating cord so that the detonating cord is held in place relative to the holding member.Detonating cord cutter Owen Oil Tools, Inc.
