Definitions
- Dry manufacture of pyrotechnic articles pyrotechnic objects.
- the technical field of the invention is that of pyrotechnic objects, in particular intended to be used in the field of automobile safety, for example in airbag gas generators.
- the invention relates more particularly to a process for the dry manufacture of pyrotechnic objects, in particular intended to be used in the field of automobile safety. It also relates to said objects, new Persian, and their uses.
- New propellants used in automotive safety may have a load factor higher than 95% and it is then necessary to use another manufacturing process.
- This manufacturing method is for example the compression using a compression machine or a pelletizer.
- pellets The production of pellets is based on the following steps:
- a granulation step which may, itself, possibly be followed by a shaping step of the compressed objects.
- US Pat. No. 6,143,102 describes a pyrotechnic composition that can be used in the form of pellets.
- a pyrotechnic composition comprises guanidine nitrate, basic copper nitrate and one or more metal oxides. It is obtained by wet process.
- the granulation step makes it possible to obtain granules. The formation of granules is necessary in order to obtain a suitable flow of the material to the downstream pelletizer and thus to allow its proper operation.
- the granulation can be carried out by different routes and for example in "slurry" (mud or paste in English).
- the "slurry" route consists in putting the charges in solution in a solvent, for example water and then evaporating the solvent.
- the evaporation of the solvent can be carried out for example by atomization.
- Spraying involves spraying the solution into fine droplets in a stream of hot air to crystallize the material to form granules.
- This type of known manufacturing process has the disadvantage of being quite expensive and having low productivity.
- the granules obtained are then compressed in a pelletizer to form pellets of pyrotechnic compounds.
- US Patent 5,489,349 describes original pyrotechnic objects and their method of production. According to said process, from powders, small fragments are first generated by compacting. Said small fragments are then agglomerated by compression at low pressure. Said small fragments retain their individuality in the structure of the final product.
- the object of the invention is therefore to provide a method of manufacturing pyrotechnic objects, simple, having a very satisfactory productivity, and a low investment cost.
- This goal is achieved by combining a technology (dry process) with a selection of raw materials.
- compacted objects such as pellet or small ball, directly resulting from a compaction / compression step
- the process of the invention is particularly suitable for compositions with a high level of charge (greater than 95%, even (almost) 100%) and of which at least one of the charges flue. This is the case for example compositions containing guanidine nitrate.
- the method of the invention is a method for the dry manufacture of pyrotechnic objects which comprises:
- the pulverulent raw materials in question comprise at least one reducing filler chosen from guanidine derivatives (such as guanidine nitrate: NG), metal hydrides (such as TiH 2 ), alkali metal hydrides (such as LiH) and alkalino -terrous (such as CaH 2 ); and at least one oxidizing charge selected from alkali metal nitrates (such as K, Na and Li nitrates), alkaline earth metal nitrates (such as Sr, Be and Ba nitrates) and nitrates basic metals (such as basic copper nitrate, BCN); at least one of said reducing and oxidizing charges having the property of flowing.
- guanidine derivatives such as guanidine nitrate: NG
- metal hydrides such as TiH 2
- alkali metal hydrides such as LiH
- alkalino -terrous such as CaH 2
- the pulverulent raw materials in question preferably comprise at least one guanidine derivative.
- they comprise guanidine nitrate.
- said pulverulent raw materials comprise guanidine nitrate (NG) and basic copper nitrate (BCN).
- NG guanidine nitrate
- BCN basic copper nitrate
- said raw materials do not contain any other oxidizing or reducing charges than said guanidine nitrate (NG) and basic copper nitrate (BCN).
- the mixture of pulverulent raw materials is used by any mixing technique suitable for mixing such materials (powders).
- Compaction is generally implemented by passing the mixture of raw materials between two rolls, rotated in opposite directions. A roller compactor is therefore generally used. Compaction pressures are generally between 1500 and 6000 bar.
- the mixture of raw materials obtained at the end of the mixing step can be transferred, to undergo the compaction step, by a monovis or multivis system.
- the method of the invention includes a (single) simultaneous step of dry compaction and compression, at the conclusion of which (directly) pellets or small balls of a volume are obtained (directly). between 10 mm 3 and 2 cm 3 .
- This single compaction / compression step can be performed within a roller compactor, the outer surface of at least one cylinder being hollowed out with cells of adequate dimensions.
- the raw material mixture is compressed within said cells.
- the roller compactor has cells (corresponding) on the surface of each of its two cylinders.
- Pellets and small balls volumes between 10 mm 3 and 2 cm 3 have been reported . This usually corresponds to pellets and small balls whose mass is between a few tens of milligrams and 10 grams.
- pyrotechnic objects that can be obtained by the first variant of implementation of the method, as described above; objects, of the pastille or small ball type, having the volume and the composition as specified above;
- the method of the invention comprises a "conventional" dry compaction which generates a ribbon of compacted material.
- the surface of the cylinders of the intervening compactor is not worked. She is perfectly flat.
- the compacting pressure is generally between 1500 and 6000 bar, regardless of the exact variant of implementation of said compaction: compaction / compression or "conventional" compaction.
- the ribbon of compacted material obtained after the implementation of a "conventional" dry compaction is generally not valued as such. It is used to feed a granulator.
- the method of the invention in the context of its second implementation variant, therefore generally also comprises dry granulation of the compacted mixture. It can be summarized as follows: dry mix + dry compaction + dry granulation.
- Dry granulation is generally carried out by forced passage of the compacted mixture through a calibrated grid.
- a forced passage is generally made using a rotor which causes the fragmentation of said compacted mixture against said grid.
- Dry granulation is therefore generally implemented using one or more granulators each consisting of a rotor and a calibrated grid.
- the granulation can advantageously be supplemented by sorting the granules obtained, in order to obtain perfectly calibrated granules.
- the rejected granules or non-calibrated material residues are advantageously reused (recycled in the process) to undergo a new granulation step.
- pyrotechnic objects - this time granular type, advantageously granulated calibrated - can be obtained directly used in pyrotechnic systems, such as gas generators.
- These granules generally have dimensions of the order of a few hundred microns to a few millimeters; their dimensions remain generally less than 5 mm.
- Such granules can in particular be obtained, from the raw materials identified above, very dense; that is to say having a density greater than 90% of the theoretical density.
- pyrotechnic objects that can be obtained by the second variant of the process of the invention supplemented by dry granulation, as described above; granule type objects having the density and composition as specified above;
- the process of the invention allows the preparation of such granules, which can be used directly.
- the method of the invention in the context of its second implementation variant, may comprise, following the granulation step, a step of dry compression of the granules obtained. It can be summarized as follows: dry mix + dry compaction + dry granulation + dry compression.
- the granules obtained can therefore, according to another alternative embodiment of the method of the invention, serve to feed a compression machine.
- the pressure applied to the granules is generally between 1500 and 6500 bar, to obtain dense objects of thickness close to 2 mm. This pressure applied to the compression is generally greater than the pressure applied to the compaction.
- the compression implemented on the granules of the invention makes it possible to obtain dense compressed pyrotechnic objects (having a density greater than 90% of the theoretical density), in particular of the pellet type (the compression step is then implemented in a pelletizer), wafer or monolith. This list is not exhaustive.
- pyrotechnic objects obtainable by the second variant of the process of the invention supplemented by dry granulation and dry compression, as described above; objects of the compressed objects type (for example, pellets, wafers, monoliths, etc.) having the density and the composition as specified above;
- the selected technology allows, in particular, from the selected raw materials (in particular NG + BCN); + the direct obtaining of pellets and small performing balls; + obtaining directly usable granules.
- FIG. 1 is a schematic view of an embodiment of the manufacturing method. according to the invention
- FIG. 2 represents, in plan view, the cycle of a rotary pelletizer that can be used in the implementation of a variant of the method according to the invention
- FIG. 3 represents an example of compacting cylinder comprising cells for directly obtaining compacted / compressed objects.
- the manufacturing method according to the invention comprises a mixing step 1 of the raw materials forming the composition.
- mixing can be carried out using various devices known in the state of the art.
- the mixing can be carried out using a "turner" 10, a convective mixer 11 screw or for example a mixer 12 convective pale.
- the mixture of constituents is made dry.
- the mixture obtained then undergoes a compaction step 2 and optionally a granulation step 2bis.
- this granulation step is carried out in the dry process, that is to say that it does not require the use of a solvent.
- the mixture in the form of a powder is first injected into a compactor 20 to undergo a compaction step.
- the injection along the direction (S) of advance of the material is for example carried out using a screw system 13 opening into the compactor 20.
- the compactor 20 is in the form of two cylinders (200, 201) disposed in parallel and spaced so as to leave between them a gap at which the mixture is compacted.
- the two cylinders (200, 201) are rotated about their respective axes in opposite directions and at the same speed. Pressure is applied to the material between the rolls.
- the direction of rotation of the rolls (200, 201) is chosen so as to advance the material in the forward direction (S) defined by the worm 13.
- the compacted mixture exiting the compactor 20 is for example in the form of plates (ribbons) or pellets or small balls when there is compression.
- the plates from the compactor can then be introduced into the granulator.
- granulation is carried out using a rotor 21 rotating close to a gate 22.
- the wheel 21 makes it possible to force the plate of material to pass through a gate 22.
- the plate, passing through through the orifices of the grid 22, is thus ground into granules.
- the granules obtained are then sorted so as to be of a certain size.
- a system with two superposed grids 23, 24 can be used.
- the upper grid 23 has a longer mesh length than that of the lower grid 24.
- the granules obtained, if they are of the desired size, pass through the upper grid 23 while the too large granules remain on this grid 23.
- the too small granules pass through the upper grid 23 and through the lower grid 24.
- the granules located between the two grids (23, 24), that is to say neither too small nor too large, will be either used for the manufacture of compressed objects such as pellets, wafers or monoliths (said granules are compressed for this purpose), or directly used as such. Granules that are too big and too small can be reinjected into the compactor 20.
- pelletizing step 3 The pelletization of the pyrotechnic composition (pelletizing step 3) can be carried out using a rotary pelletizer whose operating principle is shown in FIG. 2 or, for example, using a alternative tabletting machine (not shown).
- the granules are continuously poured into a hopper comprising a feed shoe 300 in front of which a number of dies 31 carried by a turret are continuously running.
- Two punches (32, 33), lower and upper, are associated with each matrix 31.
- the lower punch makes it possible to dose the granules poured into the matrix 31 by means of the shoe 300 of feed.
- a leveling device 36 then makes it possible to remove the overflow of granules from the matrix 31.
- the lower punch 32 and the upper punch 33 come closer, by example using pressure rollers 34, until compressing the granules located between them.
- the pyrotechnic compound formed by compression between the two punches is then ejected.
- the compression step can be suppressed, obtaining dense and calibrated granules that can be sufficient to feed a pyrotechnic system.
- the step of shaping granules by forced passage through the grid 22 and the compression step can be suppressed, the compression in the form of pellets or small balls being then performed during compaction.
- the each of the compacting cylinders (200, 201) has cavities (A, Figure 3).
- the cells A may have different geometric shapes, and have, for example, an oblong, square or circular section.
- each cell A of each of the cylinders (200, 201) is associated and corresponds to a cell of the other cylinder.
- the mixture of pyrotechnic material is therefore not only compacted between the rolls (200, 201) but also compressed directly in the form of pellets or small balls in the cells A.
- the suppression of the compression step ( subsequently) increases the production rate and significantly reduces the cost of production.
