Description

Verfahren zur Herstellung von Initialsprengstoffen mit definierter elektrischer Leitfähigkeit _ ._1 Gegenstand des Hauptpatentes ist ein Verfahren zur Herstellung von Initialsprengstoffen mit definierter elektrischer Leitfähigkeit, insbesondere für elektrische Zündmittel, durch Erzeugen des Initialsprengstoffes durch chemische Reaktion mehrerer flüssiger Partner auf oder in einem inerten Trägerstoff, wobei als Trägerstoff ein feinverteilter, vorzugsweise kolloidaler, elektrisch leitfähiger oder halbleitender Stoff benutzt wird, der in einem der flüssigen Reaktionspartner in disperser Verteilung gehalten wird.Process for the production of initial explosives with a defined electrical conductivity _ ._1 The subject of the main patent is a process for the production of initial explosives with defined electrical conductivity, especially for electrical detonators, by generating the initial explosive through chemical reaction of several liquid partners on or in an inert carrier, a finely divided, preferably colloidal, electrically conductive carrier material or semiconducting substance is used, which is in one of the liquid reactants is kept in disperse distribution.

Bei dem Verfahren nach dem Hauptpatent wird der auf oder in den Trägerstoff an- bzw. einzulagernde Initialsprengstoff den Partnern in Teilkomponenten zugefügt und erst beim Mischen der Partner durch chemische Reaktion erzeugt.In the method according to the main patent, the is on or in the carrier initial explosives to be added or to be stored are added to the partners in sub-components and only generated by a chemical reaction when the partners mix.

Demgegenüber wird nach vorliegender Erfindung eine Abänderung des Verfahrens vorgeschlagen, und zwar dergestalt, daß der in einem flüssigen Lösungsmittel gelöste Initialsprengstoff durch Zugabe eines flüssigen Fälimittels ausgefällt und auf oder in dem in einem der beiden Reaktionspartner dispergierten Trägerstoff zur Abscheidung gebracht wird, wobei als flüssige Fällungskomponente nur solche Flüssigkeiten verwendet werden, die kein Lösevermögen für den Initialsprengstoff besitzen, jedoch mit dem Lösungsmittel des Initialsprengstoffes mischbar oder darin löslich sind.In contrast, according to the present invention, a modification of the Process proposed, in such a way that the in a liquid solvent dissolved initial explosive precipitated by adding a liquid precipitation agent and on or in the carrier dispersed in one of the two reactants for Deposition is brought, with only such liquids as the liquid precipitation component are used that have no solvency for the initial explosive, however are miscible with or soluble in the solvent of the initial explosive.

So kann z. B. der bekannte Sprengstoff Hexanitromannit in der Weise auf eine Trägersubstanz, beispielsweise Graphit, abgeschieden werden, daß das Hexanitromannit zunächst bei Zimmertemperatur (20° C) in Azeton gelöst, dieser Lösung der Trägerstoff als Kolloid zugegeben und die Dispersion in dünnem Strahl aus einer Kapillare in Wasser von Zimmertemperatur eingeleitet wird. Dabei ist es nötig, die Mischung dauernd kräftig durchzurühren. Die Zuleitung ist unter den Flüssigkeitsspiegel zu legen.So z. B. the well-known explosive hexanitromannite in the way be deposited on a carrier substance, for example graphite, that the hexanitromannite first dissolved in acetone at room temperature (20 ° C), this solution is the carrier added as a colloid and the dispersion in a thin stream from a capillary in Room temperature water is introduced. It is necessary to keep mixing stir vigorously. The supply line is to be placed under the liquid level.

Da Hexanitromannit in Wasser unlöslich, Azeton dagegen löslich ist, beginnt das Hexanitromannit rasch mit einem Kristallisationskerneffekt auf den Trägerstoff auszukristallisieren.Since hexanitromannite is insoluble in water, whereas acetone is soluble, the hexanitromannite begins quickly with a crystallization core effect on the carrier crystallize out.
