Abstract

The invention relates to a production method of waste-containing powdery emulsion explosive. The waste-containing powdery emulsion explosive comprises the following raw materials: ammonium nitrate, calcium nitrate, urea, waste powdery emulsion explosive, water, emulsifier and oil phase. The waste powdery emulsion explosive means the rock type powdery emulsion explosive which is in moisture-adsorption, demulsification and devitrification phenomenon, and out of detonator sensitivity and detonation ability. The specific production operation steps are as follows: heating and dissolving water phase component of the powdery emulsion explosive, dividing the powdery emulsion explosive into three parts, slowly adding the water phase for three times, dissolving and dispersing to form the water phase liquor; preparing compounded oil phase by melting the emulsifier and oil phase; and under the stirring state, adding the water phase liquor in the compounded oil phase, emulsifying to obtain powdery emulsion explosive matrix. The use rate of the waste powdery emulsion explosive is more than 50%, the processing problem of the waste explosive is solved, the operation is convenient, and the production process is safe.

Description

technical field [0001] The invention belongs to the technical field of preparation of industrial explosives, in particular to a production method of powdery emulsion explosives. Background technique [0002] Powdered emulsion explosive is a new type of powdered industrial explosive developed in the 1980s. It uses a low water content oxidant solution or molten oxidant fine droplets as the dispersed phase, and specific carbonaceous fuel and emulsifier The composed oil phase solution is a continuous phase. Under certain technological conditions, a water-in-oil latex matrix is ​​formed by strong shearing, and then a powder made by spraying powder, rotary flash evaporation or crushing after cooling and solidification. ammonium nitrate explosive. Because it has the advantages of both powdered ammonium nitrate explosive and emulsion explosive, and the explosive component does not contain strong explosive, no need for bubble sensitization, excellent explosive performance, high work...
