Embodiment Construction

[0017] Brief description of the production process: The powdered ammonium nitrate passed through the ammonium nitrate pulverizer is 50%-80% through a 40-mesh sieve as a standard. At room temperature, a certain amount of powdered emulsion explosive (sensitizer) is added for mechanical mixing. A certain compound oil phase is added to the material, and the material can be discharged after mixing for 10-15 minutes. In order to solve the problem of low density of expanded ammonium nitrate explosives and powdered emulsion explosives, low blasthole filling density and volume power, in the production process, 50%-80% of crushed ammonium nitrate is controlled to pass through a 40-mesh sieve to effectively control the size of ammonium nitrate powder. The powdery emulsion explosive is filled into the gaps of the accumulated ammonium nitrate, thereby increasing the quality of the explosive per unit volume, fundamentally increasing the density of the explosive roll, and solving the problem of ...

Abstract

The powdered industrial no-TNT ammonium nitrate explosive has in its composition oxidant ammonium nitrate as main component, powdered emulsified explosive as sensitizing agent, certain amount of oil phase and no TNT. By means of technological measures, ammonium nitrate particle size is controlled effectively for reasonable gradation with powdered emulsified explosive particle, raised explosive density and raised explosive brisance per unit volume.

Description

Technical Field: [0001] Industrial powdery trapezium-free explosive is an industrial powder compounded with the oxidant ammonium nitrate as the main raw material, using powdered emulsion explosives instead of TNT in ordinary ammonium nitrate explosives, as a sensitizer, and adding a certain compound oil phase. Explosive, it is suitable for blasting operations in various places. Background technique [0002] At present, the recognized ammonium nitrate explosive is an industrial powdery ammonium nitrate explosive compounded with oxidant ammonium nitrate as the main raw material, TNT as the sensitizer, wood powder and other additives. For many years, our country has been using TNT as a sensitizer. In the process of production and use, there is a lot of dust, waste water and waste gas pollute the surrounding environment seriously, and it has caused great harm to the physical and mental health of production operations and construction personnel. Therefore, our national explosion admin...
