- all the constituents other than the binder and which are soluble in water will be mixed with the liquid phase containing the water and the hydroxylammonium nitrate before introduction of the latter into the twin-screw extruder.
- the pyrotechnic charges thus obtained can in particular be used either in pyrotechnic extinguishers to constitute the source of engine gas in these fire extinguishers, either in pyrotechnic gas generators intended to inflate protective cushions for vehicle occupants automobile.
- the installation shown in FIG. 1 basically comprises a twin-screw extruder 1 extended by an extrusion head 2, a conveyor belt 3 passing inside an oven 4 and a cutting system 5.
- the first device consists of a pipe 6 connected via a tap 7 to a tank 8 provided with an agitator 9.
- a second device feed consisting of a hopper 10 and a belt carrier 11.
- the tank 8 contains a liquid mixture A consisting with water, hydroxylammonium nitrate and, if applicable constituents other than the binder and soluble in water such as ammonium nitrate.
- the reactive constituents with respect to water are not incorporated into this aqueous liquid phase.
- the conveyor belt 11 feeds the hopper 10 with a mixture of granules B comprising granules of binder and, if necessary, granules of additives not soluble in water and in particular oxidizing granules not soluble in water such as hexogen or octogen.
- Extruder 1 is temperature controlled to have an internal temperature between 50 ° C and 60 ° C when the binder is polyvinyl alcohol.
- the liquid phase A and the granules B are mixed in the extruder 1 to form, by gelation of the binder, a composite paste with an amorphous structure which is extruded through the extrusion head 2 in the form of a profiled rod 12.
- This rod may be a simple cylindrical strand, possibly provided with internal channels, to give, after cutting, loose grains or be a rod of larger dimensions, with, if necessary, a worked external profile, to give after cutting. solid or annular blocks.
- This rod 12 is led through the conveyor belt 3 through a heated oven to cause hardening of the gelled binder.
- the binder is polyvinyl alcohol
- the temperature of the oven will be close to 80 ° C. and the residence time of the rod in the oven will be a few minutes.
- Example 1 Example 2 water 8 15% polyvinyl alcohol 20% 15% hydroxylammonium nitrate 68.5% 66.5% ammonium nitrate 3.5% 3.5%

De manière particulièrement préférée tous les consitutants autres que le liant et qui sont solubles dans l'eau seront mélangés à la phase liquide contenant l'eau et le nitrate d'hydroxylammonium avant introduction de cette dernière dans l'extrudeuse bi-vis.
Le premier dispositif consiste en un tuyau 6 relié par l'intermédiaire d'un robinet 7 à un bac 8 muni d'un agitateur 9.
Ce jonc 12 est conduit par l'intermédiaire de la bande transporteuse 3 au travers d'une étuve chauffée pour provoquer le durcissement du liant gélifié. Lorsque le liant est l'alcool polyvinylique la température de l'étuve sera voisine de 80°C et le temps de séjour du jonc dans l'étuve sera de quelques minutes.
