Abstract

The invention relates to the technical field of explosives and production thereof, and relates to an expanded ammonium nitrate explosive produced by use of trinitrotoluene wastewater and a production method thereof. The expanded ammonium nitrate explosive is produced by the production method shown as follows: the first step, ammonium nitrate, a solvent and an expanding agent are respectively weighed according to the weight ratio of ammonium nitrate: solvent: expanding agent being 100:10:0.15, wherein the solvent is a solution comprising the trinitrotoluene wastewater and purified water according to the weight ratio of trinitrotoluene wastewater: purified water being 20:80-100:0. According to the expanded ammonium nitrate explosive produced by use of the trinitrotoluene wastewater and the production method thereof, the expanded ammonium nitrate explosive is produced by use of the trinitrotoluene wastewater for full or partial replacement of water required for the production of the expanded ammonium nitrate explosive, the trinitrotoluene wastewater is not needed to be treated by complex processes, energy consumed by the treatment of the trinitrotoluene wastewater is saved and the cost is saved, at the same time the limitation of the treatment of the trinitrotoluene wastewater can be avoided, and further, waste materials can be recycled, energy can be saved, and environment can be protected.

Description

technical field [0001] The invention relates to the technical field of explosives and their production, and relates to expanded ammonium nitrate explosives produced by using trinitrotoluene wastewater and a production method thereof. Background technique [0002] Trinitrotoluene (TNT) is mainly used in the manufacture of high-velocity, high-power mixed explosives and is an important raw material for explosives. During the production and use of trinitrotoluene, waste water is inevitably produced. The waste water is red or dark brown, commonly known as "red water", which is very easy to pollute water and soil, and has great toxicity to human and animal bodies . Wastewater contains a variety of organic substances, mainly trinitrotoluene (TNT), and a very small amount of various isomers of dinitrotoluene and aminodinitrotoluene. The chemical properties of trinitrotoluene are stable, and it does not precipitate or separate after being dissolved in water, so it is difficult to h...
