Explanation

Powdery mixture with ammonium nitrate as the main component and combustible agent, sensitizer and other additives (dampproofer, surfactant and flash reducer, etc.). Common combustible agents are wood flour, pitch, paraffin, aluminium powder and diesel oil, and sensitizer is 2,4,6-trinitrotoluene or hexogen. The explosion energy is large and the detonation sensitivity is high, which can be used for both civilian and military purposes. The biggest drawback is moisture absorption and poor water resistance. There are many kinds of them. According to their composition, they can be divided into two categories: single explosive containing and single explosive free. According to their water resistance, they can be divided into two categories: water resistant and non water resistant. According to their use, they can be divided into military and civilian categories. In China, the latter can be divided into three categories: rock type, open-air type and coal mine safety type. Amonit from abroad is for civilian use. The most common military is Amato and Amonal, and some military ammonium nitrate explosive contain hexogen or guanidine nitrate. Generally, one stage mixing method (high-temperature heavy weight method) or two stage mixing method (low-temperature light weight method) is used to generate by a wheel mill, and is widely used in civil blasting.
