The explosive charge is the explosive mass which is brought into direct contact with solid objects in order to destroy them, regardless of whether this charge is loosely placed, placed and covered or placed in a borehole.
These are either military explosives or civil explosives (e.g. gelatinous explosives , powdered explosives or emulsion explosives ), which usually consist of the following substances or their mixtures:
Explosives are explosives that explode at high detonation speeds (3,500 to 9,000 m / s) . Through this rapid release of energy and the subsequent development of explosive clouds under high pressure, they have a destructive effect on their surroundings.
Explosives are often used to destroy obstacles in order to gain space behind or next to them. They are therefore used, for example, in mining or to blow open doors or walls by the police or the military . In fragmentation hand grenades, for example, they are used to disperse metal fragments as widely as possible (which were previously in a closed jacket around the explosive charge), which in turn penetrate the human body due to their high speed and the associated impulse and are intended to injure or kill the person concerned.
Unusual areas of application can also be found in the technical field: For example, explosive charges can be used to connect two different metal plates (similar to bimetal ) , as in explosion welding .
