Definitions

the present invention relates to improvements made to the continuous manufacturing and packaging of syrupy explosive compositions, having the property of solidifying rapidly, without sticking, so as to be sufficiently rigid and coherent to allow packaging in a paper case on a packaging machine. '' cutting type packing.
syrupy explosives have appeared on the market (also called “boullies” or “slurry”) in which the detonation support is provided by the redox reaction which takes place after ignition, between a prepared oxidizing solution hot, mineral or organic salts dissolved in water and a reducing premix consisting of solid combustible materials, mainly aluminum of different types, excluding any traditional explosive material proper.
a prepared oxidizing solution hot, mineral or organic salts dissolved in water and a reducing premix consisting of solid combustible materials, mainly aluminum of different types, excluding any traditional explosive material proper.
Such explosives are described in particular in United States patent 3,121,036 and in Belgian patent 575,043.
the sensitivity is mainly due to the presence of aluminum of the "paint" type while a complementary sensitivity is ensured as a function of the density of the gas microbubbles resulting from a chemical reaction within the mass. ; a more or less rubbery plastic texture is imparted to the explosive by gelation, by means of a crosslinking agent, of the guar gums present in the formula.
compositions lies in an increase in safety during manufacture, during storage, transport and use, while the methods of implementation offer a more extensive diversification than for conventional explosives.
this type of composition has a double defect.
the detonation capacity and the ability to transmit from one cartridge to another require increasingly fine sensitizers, and this at increasing rates; on the other hand, the plastic consistency of the cartridges makes them compressible, which in blast holes, may lead to the detonation being stopped under the effect of the compression waves which propagate in front of the detonation front.
the sensitivity could be increased so as to already ensure detonation for cartridge diameters less than 20 mm; an important additional advantage is due to the fact that certain explosives of this species can have a solid texture, instead of having a plastic consistency, which allows them to better resist the effects of the compression waves described above; the efficiency is all the greater as the manufacture is carried out from a solution rich in ammonium nitrate, that is to say at a higher crystallization point.
the disadvantage which the generally improved explosive porridge presents is a great difficulty of conditioning: the viscosity of some of them is such as the usual means (machines of the chub-pack type or barrels of extrusion) are not suitable.
a conventional sealing of the product cooled in tanks as it is carried out for traditional explosives (dynamites for example) from an extrusion screw or a cutting machine of the Rollex type offers the double disadvantage of being a discontinuous process and of completely desensitizing the explosive.
the cooled product is in the form of a solid mass, however powdery and brittle, too inconsistent to be easily cartoned. This is particularly the case for the composition described in US Patent 4,033,264 which describes the product obtained as a friable gelled explosive composition.
the present invention therefore aims to improve syrupy explosive compositions and to offer a process for their preparation which makes it possible to obtain explosives with a final solid texture allowing solidification which makes the product rigid but nevertheless sufficiently coherent for packaging in a case. paper on a cartoning machine of the cutting type is facilitated.
the aim is to obtain a product which solidifies rapidly without however sticking.
the invention relates to a continuous process for the production of cartridge-like syrupy compositions, characterized in that an oxidizing solution prepared hot, known per se, containing mineral or organic salts dissolved in water, and a premix are mixed.
reducing agent consisting of solid fuels based on combustible metals and a hardening agent introduced in solid form, prior to the final solidification of the composition, the mixture then being cartridge-filled using a cutting machine, preferably a cartoner Rollex type.
said mixture undergoes rapid and immediate cooling at the outlet of the device for mixing the oxidizing solution and the reducing premix.
Cartridges prepared using this composition and according to the above method are surprisingly characterized by aptitude characteristics of 6 cm in air in the case of the invention.
composition of the invention is no longer compressible, no "channel effect" is observed, as is the case for the composition described in Belgian patent 698,434 in which setting or hardening of the composition is ensured by metal salts.
the hardening agent necessary for extrudability is of the carboxymethylcellulose type; its content according to the invention, expressed as a percentage by weight relative to the final formula of the explosive composition is advantageously between 1 and 3%, preferably between 1.5 and 2.5% and very particularly advantageously is from around 2%.
Carboxymethylcellulose is a well known product in the porridge explosives industry; it is often cited as a fuel and thickener; this is the case in DE-A patents 1,813,173; 2,826,589 and 2,643,499, in patents FR-A 1,550,925 and 1,244,201 or also in patent US-E 26,115, US-A 3,235,425 and 3,524,777; certain particular properties have been found and claimed for it, such as for example to obtain better crosslinking (US-A patents 3,344,004 and 3,251,781) or better water resistance as well as longer storage (GB patent- A 1.238.818) or even improved stability (patent FR-A 2.006.804); in all these cases, it is an integral part of the oxidizing solution: it is associated with the aqueous phase either directly or in premix with glycol (GB-A 2 013 173 patent).
the carboxymethylcellulose acts as a hardening agent, essential for cloudability on a cartridge-type cutting machine, provided that it is incorporated, necessarily, in the solid part of the composition (that is to say with the reducing premix); it is therefore not, as in the aforementioned documents, a simple thickening (which would only have effects on the greater or lesser viscosity of the product), neither a crosslinking action (which would make the dough too plastic for the intended purpose), nor an improved water resistance or stability action.
the action of the hardening agent can be enhanced by the presence of a crosslinking agent based on chromium or antimony which acts on guar gum when the latter is present.
syrupy explosive compositions are well known to those skilled in the art and the invention extends to the compositions of the state of the art having the characteristic of the invention of containing a hardening agent in the solid combustible premix. . It appeared that the presence in the solution of a crystal regulator of the family of methyl naphthalene sulfonates sodium gives particularly favorable results.
a solution at 80 ° C. is prepared containing: and on the other hand, a premix containing:
the mixing in the proportion 87 parts by weight of solution and 13 parts by weight of premix is carried out by simple passage in a slurry mixer from where it is carried, either by gravity or by pumping, on the conveyor belt of the machine Rollex, cooled by water and air, and conveyed under the knife of the machine, in the form of a carpet ready for cutting, at the temperature of about 40 to 45 ° C, that is to say sufficiently cooled and coherent to be stuffed.
Each cut is individually molded in a paper case which, once closed, ensures and maintains the shape of the cartridge thus obtained.
the density of the explosive which conditions the weight of the cartridges, can, if necessary, be adjusted by bringing to the mixer at the same time as the solution and the premix of Example 1, 0 to 0.8 parts by weight of NO 2 Na in solution 75/25; the explosive preferably with 0.4 part by weight of N0 2 Na, packed in 30 mm / 200 g gives, without confinement, an aptitude in air of 6 cm and a detonation speed of 3800 to 4100 m / s per priming with a detonator at 440 mg of hexogen, at a density of 1.10-1.15.
Example 1 determines whether the atomized aluminum is replaced by silicon we obtain, at density 1.10:
the explosive power of Example 1 determined with a lead block is 400 cc, that is to say equivalent to that of a very good quality dynamite.
the process remains compatible with all the formulas based on the solution of Example 1 in which the content of combustible metal in the premix varies from 0 to 8 parts by weight. This will be illustrated in the following two examples giving the characteristics of the two extreme formulas.
the effect of the self-crosslinking guar added to the premix can be reinforced by 0.5 part by weight of a crosslinking agent based on chromium or antimony.
Example 2 To 86 parts by weight of the solution of Example 1, 14 parts by weight of a premix consisting of: The rest of the operations take place as in Examples 1 to 4. The product has excellent anti-sticking properties and can be easily implemented on a cartoning machine.
the hardening agent of the carboxymethylcellulose type can also be combined with the polyacrylamide.
Example 1 87 parts by weight of the solution of Example 1 are mixed with 13 parts by weight of the following premix: The characteristics of the products are the same as for Example 1.
Example 1 The solution of Example 1 is replaced by the following solution: The rest of the operations are carried out as in the previous examples and the results obtained are similar.
