What is in a blasting cap?
A detonator, frequently a blasting cap, is a device used to trigger an explosive device. This compound is formed from lead azide, lead styphnate and aluminium and is pressed into place above the base charge, usually TNT or tetryl in military detonators and PETN in commercial detonators.
What is a detonating device?
explosive device. Share Give Feedback External Websites. Blasting cap, also called Detonator, device that initiates the detonation of a charge of a high explosive by subjecting it to percussion by a shock wave.
What explosive is used in blasting caps?
mercury fulminate
Fuse caps contain explosives like mercury fulminate, lead azide, and lead styphnate. Fuse caps are usually small metal tubes 1” – 2” in length and approximately ¼” in diameter. Fuse caps can detonate if subjected to heat, shock, or static electricity.
Are blasting caps legal?
No person shall store or keep blasting caps, detonating or fulminating caps, or detonators in a magazine in which any other type of explosive is stored or kept.
How much power does a blasting cap have?
0.25 amps
Blasting Caps are designed to have a minimum firing current of 0.25 amps.
What is the most powerful explosive material?
PETN. 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 Gelignite mean?
: a dynamite in which the adsorbent base is largely potassium nitrate or a similar nitrate usually with some wood pulp.
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. Nonel is a contraction of “non electric”.
What is a Class B explosive?
Class B Explosives – a term formerly used by the U.S. Department of Transportation to describe explosives that possess a flammable hazard. (Currently classified as Division 1.3 materials.)
What sets off a blasting cap?
Blasting cap The primer may be set off by the brief application of heat (from a burning fuse or an electrically heated wire), by friction, or by mechanical shock (like the impact of the firing pin of a gun).
How are blasting caps used in the military?
Blasting Caps (Electric and Non-Electric) It is used to detonate all military explosives. When initiated by time-blasting fuse, primer or detonating cord, the ignition charge detonates the intermediate charge which detonates the base charge, which initiates the explosive charge.
How are ordinary detonators used in the military?
Ordinary detonators usually take the form of ignition-based explosives. While they are mainly used in commercial operations, ordinary detonators are still used in military operations. This form of detonator is most commonly initiated using a safety fuse, and used in non time-critical detonations e.g. conventional munitions disposal.
Why was the detonator used in the Manhattan Project?
This type of detonator was invented in the 1940s as part of the Manhattan Project to develop nuclear weapons. The design goal was to produce a detonator which acted very rapidly and predictably.
What are the different types of detonators for lead?
Well known detonators are lead azide [Pb (N 3) 2 ], silver azide [AgN 3] and mercury fulminate [Hg (ONC) 2 ]. There are three categories of electrical detonators: instantaneous electrical detonators ( IED ), short period delay detonators ( SPD) and long period delay detonators ( LPD ).
