How does detonation cord work?

Detonation Cord consists of a high-explosive (either PETN or RDX) core wrapped in a reinforced, waterproof, olive-drab plastic coating that transmits a detonating wave. When the explosive core is detonated by a blasting cap, the wave travels along the cord to other blasting caps or explosive charges attached to it.

What color is det cord?

Both detonating cord and time fuse are olive drab in color, but time fuse has a black core (black powder) and detonating cord has a white core (PETN).

What is primer cord used for?

Primaline® Detonating Cord PRIMALINE det cords are flexible linear explosives with a core of PETN explosive encased in a plastic outer jacket. PRIMALINE detonating cords are designed for use as trunklines and/or downlines in abrasive mining, quarrying and construction applications.

What is Codex wire?

Cordtex is a type of detonating cord generally used in mining. It uses an explosive core of pentaerythritol tetranitrate (PETN) inside its plastic coating. It is used to “daisychain” a sequence of explosives together. It can also be used in short lengths in simple boobytraps and early warning devices.

What is the most powerful eXplosive material?

One of the most powerful explosive chemicals known to us is PETN, which contains nitro groups which are similar to that in TNT and the nitroglycerin in dynamite. But the presence of more of these nitro groups means it explodes with more power.

What is Pek explosive?

EPX-1 is a new plastic explosive (in the research stage) which has been prepared for military and civilian applications. EPX-1 explosive contains pentaerythritol tetranitrate (PETN) with different particle size as explosive filler bonded by nonenergetic thermoplastic binder plasticized by dibutyl phthalate (DBP).

How much does detonation cord cost?

DETONATING CORD

Grain/Foot	Length	Price
40	1 Spool (1,000 Feet)	$1,075.00
50	100 Feet	$125.00
50	1 Spool (1,000 Feet)	$695.00
80	100 Feet	$175.00

Is det cord flammable?

With the PETN exploding at a rate of approximately 6400 m/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 detonating high explosives.

What is a high velocity explosive?

High Explosives: A high explosive is any chemical mixture that detonates with a reaction velocity over 5000 feet per second.

What is the most powerful high explosive?

HMX is the most powerful high explosive produced in industrial quantities today. It is a relatively insensitive, temperature-stable and safe-to-handle high explosive that makes it useful in a variety of applications both in military and civilian end products.

What kind of cord is a detonating cord?

Detonating cord. Detonating cord (also called detonation cord, detacord, det. cord, detcord, primer cord or sun cord) is a thin, flexible plastic tube filled with PETN (pentaerythritol tetranitrate). With the PETN exploding at a rate of approximately 4 miles per second, any common length of det cord appears to explode instantaneously.

What kind of cord explodes at 4 miles per second?

Detonating cord (also called detonation cord, detacord, det cord, detcord, primer cord or sun cord) is a thin, flexible plastic tube filled with PETN ( pentaerythritol tetranitrate ). With the PETN exploding at a rate of approximately 4 miles per second, any common length of det cord appears to explode instantaneously.

When do you use the velocity of detonation?

The velocity of detonation is sufficient to use it for synchronising multiple charges to detonate almost simultaneously even if the charges are placed at different distances from the point of initiation. It is used to reliably and inexpensively chain together multiple explosive charges.

How big is a 50 grain detonator cord?

For example, “50 grain det. cord” refers to detonating cord which has 50 grains of explosive per foot of length—or approximately 10 g/m.

How does detonation cord work? Detonation Cord consists of a high-explosive (either PETN or RDX) core wrapped in a reinforced, waterproof, olive-drab plastic coating that transmits a detonating wave. When the explosive core is detonated by a blasting cap, the wave travels along the cord to other blasting caps or explosive charges attached to it.…
