Definitions

the present invention is in the field general of industrial explosives for civil use.
It relates to new explosive emulsions particularly suitable for slaughter hard rocks in quarries or on construction sites.
Water-in-oil cartridge-type explosive emulsions are well known to those skilled in the art.
emulsions Compared to the usual dynamites, which contain 25% to 45% nitroglycerin, emulsions aforementioned explosives offer safe use and very clearly improved manufacturing. In counterpart, they are much less powerful and release less explosion energy.
a person skilled in the art has long been at the search for explosive emulsions of the aforementioned type, presenting both safety and sensitivity to initiation of cartridge-containing explosive emulsions known and the power of dynamites, namely a detonation speed close to 6000 m / s measured in diameter 80 mm confined, and a total energy measured under water greater than approximately 1100 cal / g.
sensitizing molecules such as nitrate hydrazine and organic nitrates, especially amine nitrates such as methylamine nitrate, or well again reaction catalysts such as copper chloride, or even very oxidizing reagents such as chlorates or perchlorates.
Patent application EP 598 115 describes for example energetic explosive emulsions based on nitrate ammonium containing an amine nitrate and / or nitrate hydrazine as a sensitizer.
US Patent 4,371,408 describes explosive emulsions based on ammonium nitrate and sodium nitrate sensitized with an amine nitrate and containing CuCl 2 as a detonation catalyst.
detonation velocity close to 6000 m / s measured in diameter 80 mm confined and a total energy measured under water greater than 1100 cal / g, which can even exceed 1200 cal / g, with a energy efficiency greater than 80%.
the object of the present invention is therefore to new cartridge type explosive emulsions water-in-oil sensitized by a gas phase dispersed and comprising ammonium nitrate, sodium nitrate, water, fuel hydrocarbon, emulsifier and aluminum.
the aforementioned weight contents are expressed by compared to the sensitized explosive emulsion and have to be understood limits included.
the above-mentioned new explosive emulsions according to the invention are in particular devoid of chlorates and perchlorates, for example those of ammonium, of metals alkaline or alkaline earth, devoid of molecules sensitizers of the organic nitrates type, by example of alkylamine nitrates and nitrates alkanolamines, or hydrazine nitrates, for example example of hydrazine nitrate and methylhydrazine, free of metal catalysts such as copper chloride.
chlorates and perchlorates for example those of ammonium, of metals alkaline or alkaline earth
molecules sensitizers of the organic nitrates type by example of alkylamine nitrates and nitrates alkanolamines, or hydrazine nitrates, for example example of hydrazine nitrate and methylhydrazine, free of metal catalysts such as copper chloride.
the hydrocarbon fuel can be a mixture of several hydrocarbon fuels and the emulsifier a mixture of several emulsifiers.
the hydrocarbon fuel can be aliphatic, cycloaliphatic, aromatic, saturated or unsaturated.
We may for example include toluene, xylenes, petrol, kerosene, fuel oil, paraffins, oils, especially paraffinic oils or naphthenics, fatty acids and their derivatives, waxes, and mixtures thereof, namely any mixture of at least minus two of the above compounds.
the hydrocarbon fuel is chosen from the group consisting of oils, waxes, paraffins and their mixtures.
the emulsifier can be any well known emulsifier skilled in the art promoting physical stability water-in-oil emulsions by lowering the interfacial tension between the 2 phases of the emulsion.
the emulsifier is preferably chosen from the group consisting of polymeric emulsifiers which simultaneously comprise hydrophilic chains and hydrophobic chains, such as derivatives of polyisobutylene and succinic anhydride, amines, in particular those containing from 12 to 24 atoms of carbon, fatty acid esters such as monooleate sorbitan, sorbitan laurate, palmitate sorbitan and sorbitan stearate, alkylaryl sulfonates, and mixtures thereof.
polymeric emulsifiers which simultaneously comprise hydrophilic chains and hydrophobic chains, such as derivatives of polyisobutylene and succinic anhydride, amines, in particular those containing from 12 to 24 atoms of carbon, fatty acid esters such as monooleate sorbitan, sorbitan laurate, palmitate sorbitan and sorbitan stearate, alkylaryl sulfonates, and mixtures thereof.
Aluminum used in the context of this invention is finely divided, preferably powdery.
Its particle size is generally between 0.1 ⁇ m and 250 ⁇ m, better still between 0.5 ⁇ m and 150 ⁇ m.
the explosive emulsions according to the invention are sensitized by a dispersed gas phase, according to a method well known to those skilled in the art.
nitrites such as nitrite sodium
ammonium ions of ammonium nitrate cause in situ formation nitrogen.
This reaction can be accelerated by temperature rise and / or by a urea, thiourea or thiocyanate type.
the emulsions explosives according to the invention contain between 13% and 17% by volume of dispersed gas phase, better still between 14% and 16% by volume.
the sum of the weight contents of ammonium nitrate and sodium nitrate is between 73% and 77%, better still between 74% and 76%.
the content by weight in ammonium nitrate is between 61% and 67%, better still between 62% and 65%.
the content water weight is between 4.5% and 6.5%, better still between 5% and 6%.
the content aluminum weight is between 13% and 17%, better still between 13.5% and 16.5%, better still between 14% and 16%.
the content by weight in emulsifier is between 1.5% and 4%, better still between 2% and 3.5%.
the content weight in hydrocarbon fuel is between 0.7% and 4%, better still between 0.8% and 3%, better still between 1% and 2%.
the density of explosive emulsions according to the invention is preferably between 1.26 and 1.40, better still between 1.28 and 1.37, their speed detonation measured in diameter 80 mm confined is between 5500 m / s and 6300 m / s, better still between 5750 m / s and 6300 m / s, and their total real energy, determined under water, is between 1100 cal / g and 1400 cal / g, better still between 1200 cal / g and 1400 cal / g.
the explosive emulsions according to the invention can be obtained by analogy with any process already known obtaining water-in-oil explosive emulsions sensitized by a dispersed gas phase and comprising ammonium nitrate, sodium nitrate, water, a hydrocarbon fuel, an emulsifier and aluminum.
the emulsifier may also not be incorporated into this hydrocarbon fuel stage.
the emulsion may be obtained using a turbine and simultaneously homogenized for example using a pale clover.
the 2 phases, and the emulsifier if it is not incorporated into the phase oily are pumped using metering pumps in supply lines for an foam concentrate.
aluminum, microspheres and / or the chemical gas generator are from preferably incorporated into the emulsion by kneading, in the mixer used to make the emulsion, or in a planetary shaker.
the adjuvants are preferably incorporated continuously, for example using auger, in a mixer in which also pours the water-in-oil emulsion into from the foam concentrate.
the sensitized explosive emulsion thus prepared is then sealed, possibly after a first cooling, manually or automatic, in sheaths such as paper or plastic, using an installation of packaging well known to those skilled in the art.
the cartridges obtained are then generally cooled, for example with cold water or air cold depending on the nature of the sheath, so as to stabilize the final emulsion obtained.
the aqueous phase (a) and the fatty phase (b) are then introduced into a mixer, then we realize the emulsion using a turbine while homogenizing simultaneously mixing with a pale clover.
the temperature self-maintains between 105 ° C and 110 ° C in the mixer.
the mass of explosive emulsion that we introduce in each sheath is evidently deduced from the volume of the cartridge sought, the density of the emulsion explosive that is measured before the packaging and the addition of sodium nitrite, and the volume rate sought for gas phase (about 15%).
the volume level of desired gas phase is reached and the chemical reaction of formation is then stopped of nitrogen by abruptly lowering the temperature of the emulsion, which is easily achieved by spraying cold water on the cartridges.
