What are detonators in explosives?
A detonator, frequently a blasting cap, is a device used to trigger an explosive device. A blasting cap is a small sensitive primary explosive device generally used to detonate a larger, more powerful and less sensitive secondary explosive such as TNT, dynamite, or plastic explosive.
What are the 3 categories of high explosives?
High explosives are divided into three main categories, Primary (or Initiating) High Explosives, Secondary High Explosives, Boosters and Secondary High Explosives, Main Charge.
What explosive is in a blasting cap?
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.
What is an example of a primary explosive?
Primary explosives are used as detonators: that is, to cause the secondary explosives to explode. Mercury fulminate, picric acid, lead azide, nitroglycerine and iodine nitride are examples of primary explosives. TNT, dynamite, hexogen, HMX and Torpex are examples of secondary explosives.
What is Nonel blasting?
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.
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.
What is the most powerful military explosive?
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.
Are blasting caps illegal?
What are tertiary explosives?
Tertiary explosives, also called blasting agents, are so insensitive to shock that they cannot be reliably detonated by practical quantities of primary explosive, and instead require an intermediate explosive booster of secondary explosive. ANFO can be a tertiary explosive if its reaction rate is slow.
What is primary and secondary explosive?
type of chemical explosion …into two categories, primary and secondary. Primary explosives detonate by ignition from some source such as flame, spark, impact, or other means that will produce heat of sufficient magnitude. Secondary explosives require a detonator and, in some cases, a supplementary booster.
