Co to jest?

Explosive materials are substances or mixtures that undergo a rapid, self-sustainalg chemical reaction, releasing a large volume of hot gases and heat energy almost instantaneously. The resutting pressure wave - traveling at supersonic or subsonic speeds - causes mechanical destruction by overpressure and framentation.

Classification of Explosive Materials

Low. High Explosives

Lowexplosive deflagrate rather than detonate. Black powder, a mixture of potassium nitrate, charcoal, and sulfur, is a classic low explosive use for pyrotechnics, safety fuse, and antique firearararms. It burns relatively slowly (around 400 m / s) and is sensitivy to sparks andd flame. High explosives detoptene, producing a supersonec shock wae.

Primary vs. Secondary Explosivs

Primary explosives are extremely sensitivy to heat, friction, and impact. They ary use in small quantities to initiatione larger charges - often found in blasting caps, detonators, and primers. Common primary explosives included lead azide (Pb (N) contract), lead styphnate, and mercury fulminate.
