Detonating cord shall be handled and used with care to avoid damaging or severing the cord during and after loading and hooking-up. Detonating cord connections shall be competent and positive in accordance with approved and recommended methods.
What is the velocity of det cord?
The velocity is approximately 6,400 metres (21,000 feet) per second.
Who makes det cord?
Dyno Nobel manufactures the world’s most well known brands of detonating cord (det cord), available in a wide variety of coreloads (from 7.5 to 400 gr/ft) and either a textile jacket (Primacord®) or a plastic jacket (Primaline®), for a wide variety of mining explosive needs.
How does det cord work?
description. Detonating cord, also called Cordeau and Primacord, is a hollow cord filled with an explosive material. It is fired by a detonator and is capable of initiating the detonation of certain other explosives at any number of points and in any desired pattern.
How fast does dynamite fuse burn?
Safety fuses are manufactured with specified burn times per 30 cm, e.g. 60 seconds, which means that a length of fuse 30 cm long will take 60 seconds to burn.
Can you buy det cord in the UK?
Detonating Cord is a linear explosive consisting of a PETN powder wrapped in a flexible plastic outer coating. Manufactured in the EU, EPC-UK is able to supply a comprehensive range of cord weights for a variety of applications.
What explosive is in det cord?
cord, detcord, primer cord or sun 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.
What is c4 made of?
C-4 or Composition C-4 is a common variety of the plastic explosive family known as Composition C, which uses RDX as its explosive agent. C-4 is composed of explosives, plastic binder, plasticizer to make it malleable, and usually a marker or odorizing taggant chemical.
What is Nonel detonator?
Nonel is a shock tube detonator designed to initiate explosions, generally for the purpose of demolition of buildings and for use in the blasting of rock in mines and quarries.
What is used to detonate TNT?
TNT neither absorbs nor dissolves in water, which allows it to be used effectively in wet environments. To detonate, TNT must be triggered by a pressure wave from a starter explosive, called an explosive booster.
What are blasting agents?
BLASTING AGENT – Any material or mixture, consisting of fuel and oxidizer, intended for blasting, not otherwise defined as an explosive, provided that the finished product, as mixed for shipment or use, cannot be detonated by means of a No.
What is electric detonator?
Electronic detonators are modern, fully programmable and intelligent high strength detonators. Each detonator contains a circuit board that can be programmed to initiate at precise millisecond timing within a firing sequence.
What is the difference between high explosives and low explosives?
Explosives fall into two categories – high explosives and low explosives. The main difference between these two categories is the velocity of detonation. High explosives detonate at a rate greater than the speed of sound whereas low explosives deflagrate. Deflagration involves particle to particle burning.
