Abstract
In a first aspect, the present invention relates to a granulated explosive based on a water-in-oil emulsion with one or more oxygen carriers. water, one or more fuel carriers and emulsifier. The invention also relates to a method for producing a granulated explosive according to the invention based on a water-in-oil emulsion containing oxygen carriers, water, fuel carriers and emulsifier. The invention lastly relates to a granulated explosive obtainable using the method according to the invention and to the use of the granulated explosive according to the invention.
Claims25
A granulated explosive based on a water-in-oil emulsion, comprising:
- oxygen carrier with a mass fraction of 78 to 90%;
- water with a mass fraction of 5 to 10%;
- fuel carrier with a mass fraction of 3 to 7%;
- and
- emulsifier with a mass fraction of 0.1 to 3%.
A method for producing a granulated explosive based on a water-in-oil emulsion containing oxygen carrier, water, fuel carrier and an emulsifier, comprising:
- providing a water-containing phase with the oxygen carrier;
- providing a phase with the fuel carrier and the emulsifier;
- heating i) the water-containing phase with the oxygen carrier and, separately therefrom, heating ii) the phase comprising the fuel carrier and the emulsifier;
- uniting the water-containing phase and the phase comprising the fuel carrier and the emulsifier to form a united composition in a reactor and homogenizing the united composition to form the water-in-oil emulsion;
- cooling and granulating the water-in-oil emulsion, optionally with shaping processes;
- and optionally comminuting and classifying granules which are granulated from the water-in-oil emulsion.
