«Cordtex» and «Primacord» are two of the many brands that have been used as the umbrella term for this material. «Detonating cord» – a flexible cord containing an average core of explosives that, when detonated, has sufficient force to detonate other plugs – sensitive explosives with which it is in contact. The 2002 film We Were Soldiers showed that the detonation rope was used by U.S. cavalry troops to remove trees from a landing zone. nThe detonation cord (detonation fuse) is similar to the safety fuse, but contains a highly explosive explosive instead of black powder. The first successful, patented in France in 1908, consisted of a lead pipe, about the same diameter as the safety fuse, filled with a TNT core. n A primer cord coil was used by Alan Alda`s character, Hawkeye, in the television series M*A*S*H (season 9, episode 12, «Depressing News») to demolish his newly constructed replica of the Washington Tongue Pusher Monument. Creating a sliding knot from a detonating cord results in an improvised on-site device that can be quickly used to cut a locked door handle from a door. The detonation cord can be glued and explode into several rings on the contour of a human-sized military target, breaking a human-sized hole in wooden doors or bright interior walls. Sandblasting cord is also used directly in the demolition of buildings, where thin concrete slabs must be broken on channels drilled parallel to the surface, an advantage over dynamite because a minimum of lower explosive force can be used and smaller diameter holes are sufficient to contain the explosive. [2] Anything much more important than these uses requires the use of additional explosives. The detonation cord (also called detonation cord, detacord, detcord, detcord, primer cord or sun cord) is a thin and flexible plastic tube usually filled with pentaerythritol tetranitrate (PETN, pentrite).
Since PETN explodes at a rate of approximately 6,400 m/s (21,000 ft/s), any usual length of the detonation cord appears to explode immediately. It is a high-speed fuse that explodes instead of burning and is suitable for detonating explosives. The detonation rate is sufficient to be used to synchronize multiple loads so that they explode almost simultaneously, even if the loads are placed at different distances from the priming point. It is used to reliably and cost-effectively connect several explosive charges together. Typical applications include mining, drilling, demolition, and warfare. Class A explosives. Risk of detonation such as dynamite, nitroglycerin, picric acid, lead azide, mercury fulminate, black powder, explosive caps and detonation primer. Low-efficiency detonation cables can be used as a precision cutting load to remove cables, pipes, wiring, fiber, and other utility harnesses by placing one or more complete windings around the target. The detonation bead is used in commercial boilers to break the clinker (solidified coal ash slag) that adheres to pipe structures.
In addition, a vertically centered rope that is lowered into the water of a borehole can remove blockages that impede the flow of water. The higher-efficiency detonation cord can be used to cut down small trees, although the process is very uneconomical compared to using bulk explosives or even a chainsaw. A high-performance explosive cord placed by divers was used to remove old dock piles and other underwater obstacles. The detonating cord, also called cord and primacord, is a hollow cord filled with an explosive material. It is fired from a detonator and is capable of initiating the detonation of some other explosives at any number of points and according to any desired pattern.n In Filipino, the corresponding word mitsa was used in the phrase mitsa ng buhay, which translates to «flaming rope of life», a metaphor for something that is very likely to cause death by direct danger (for example, extreme sports, against smoking). The explosive cord is evaluated in explosive mass per unit length. This is expressed in grains per foot in the United States or grams per meter elsewhere.
