Powdered ammonium nitrate explosives, explosive mechanical mixture of species is one of the most widely used industrial explosive with medium power and a certain sensitivity. It is hygroscopic and caking after moisture sensitivity and significantly reduced power while producing gas. Energy (such as mechanical, thermal, electrical, optical) the role of primary explosive in weak external excitation, can burn occurs, and can quickly transformed into a sensitive explosive detonation. Pure ammonium nitrate is stable at room temperature for blow, collision or friction insensitive. However, at high temperatures, high pressure and material that can be oxidized there will be an explosion in the production, storage and use of safety regulations must be strictly observed.
The main characteristics of the rock ammonium nitrate explosives and Scope
More sensitive to the impact of friction but not ignite flames; allow the moisture content of not more than 0.3%; density 0.95 ~ 1.1g / mL; Brisance 12 ~ 14mm; explosive force of 280 ~ 360mL; soaking before detonation distance 4 ~ 8cm; martyrdom after flooding burst from the 2 ~ 4cm; detonation velocity 3600 ~ 3750m / s
