How do explosives work?

There are two types of explosives: low explosives such as gunpowder, and high explosives like TNT. Low explosives are generally a mixture of flammable substances and oxidation substances that burn at speed between several cm/s to 400 m/s, but usually at the bottom of this scale. High explosives are rather chemical compounds (one type of molecule) than duo - these detonate rather than deflagrate, create a supersonic shock wave of 1,000 - 9,000 m/s.

Low explosives work in the same way as hot wood or coal: together with combine with an oxidation substance, and warm and warm and warm and warm and warm and smooth gases, are formed. Depending on the oxygen level in the surrounding medium, deflagration occurs with more or less speeds and violence. Deflagration resembles detonation at higher levels.

High explosives are chemically unstable compounds, often including several nitrate groups. When it is exposed to sufficient heat or mechanical shock, high explosives suddenly change theirMolecular structure, deteriorate to reaction products and release a lot of energy in the process.

There are nine primary reaction sequences forming parts of the detonation process of high explosives, known as priorities. For example, Priority 1 includes a combination of metal with chlorine and releases excess energy in this process. Other priorities include a combination of hydrogen with chlorine, metal with oxygen, carbon and oxygen, hydrogen and oxygen, carbon monoxide and oxygen, nitrogen with itself, oxygen with each other and hydrogen with itself. In any given explosive, several of these reactions can occur, each of which releases a large amount of energy.

Since some explosives require extreme heat for firing, explosive chains must be set, where one explosive with lower energy is detonated with a blaster cap, WH, WH, WH, which provides the basis for explosion other substances.

Four Standard PopThe compound or mixture must have a qualification as an explosive include rapid gas expansion, heat generation (exothermic reaction), response speed and response initiation, which means that explosive can be ignited in a controlled manner. Another desirable quality of explosives for practical use is a limited amount of toxicity.
