composition
Binary explosives consist of two components, a solid or powdery component, usually ammonium nitrate , and a liquid, usually nitromethane . Only the mixture of the two, similar to the ANNM explosives, is capsule-sensitive and can detonate. As a rule, the mixture is only explosive for a certain period of time (a few hours) and must be destroyed after this time has elapsed.
properties
Binary explosives are of the explosive between the military and the brisanteren less explosive powder explosives .
application
Binary explosives are used for the following purposes:
- Blasting structures and parts of structures
- for clearing duds, ammunition and mines (Explosive Ordnance Disposal, EOD)
- Blasting rock
- for blasting guns
- Culture sprinkling, e.g. B. trees and wood, digging
One advantage is the problem-free storage and transportability of the individual components. Since they are not explosives, they do not fall under the Explosives Act and are therefore to be handled like chemicals. Since the quantities of the individual components are precisely matched to one another, it is not possible to halve the specified loading quantities.
