Description
Verfahren zur Herstellung von Initialsprengstoffen mit definierter elektrischer Leitfähigkeit 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 The subject of the main patent is a process for production of initial explosives with defined electrical conductivity, in particular for electrical detonators, by generating the initial explosive by chemical means Reaction of several liquid partners on or in an inert carrier, whereby 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 durch eine chemische Reaktion zum Ausfallen gebracht.In the method according to the main patent, the is on or in the carrier initial explosives to be deposited or stored through a chemical reaction to precipitate brought.
Demgegenüber wird nach vorliegender Erfindung in Abänderung des vorgenannten Verfahrens vorgeschlagen, den feinverteilten, elektrisch leitfähigen Trägerstoff in einer Lösung, besonders in einer übersättigten Lösung des Initialsprengstoffes zu dispergieren und den Initialsprengstoff sodann durch Temperaturerniedrigung und/oder Vakuumbehandlung auf oder in dem dispergierten Trägerstoff zur Abscheidung zu bringen.In contrast, according to the present invention, in modification of the aforementioned Proposed method, the finely divided, electrically conductive carrier in a solution, especially in a supersaturated solution of the initial explosive to disperse and the initial explosive then by lowering the temperature and / or To bring vacuum treatment on or in the dispersed carrier for deposition.
So läßt sich beispielsweise Silberazid dadurch auf eine leitfähige Trägersubstanz abscheiden, daß eine z. B. bei 50° C übersättigte Lösung von Silberazid in Methanol-Ammoniak, in der der Trägerstoff in kolloidaler Form in disperser Verteilung gehalten wird, einer Temperaturerniedrigung unterzogen wird, indem das Lösungsmittel im Vakuum verdampft wird, wodurch das Silberazid auskristallisiert und sich an den Trägerstoff anlagert.For example, silver azide can thereby be deposited on a conductive carrier substance that a z. B. at 50 ° C supersaturated solution of silver azide in methanol-ammonia, in which the carrier is kept in colloidal form in disperse distribution, is subjected to a temperature decrease by evaporating the solvent in vacuo, whereby the silver azide crystallizes and adheres to the carrier attaches.
Durch die Vakuumbehandlung wird einerseits der unter Normaldruck bei etwa 90° C liegende Siedepunkt des Lösungsmittels herabgesetzt, andererseits wird durch Entzug von Verdampfungswärme die Temperatur der Lösung herabgesetzt.Due to the vacuum treatment, on the one hand, the normal pressure at The boiling point of the solvent, which is around 90 ° C., is reduced, on the other hand the temperature of the solution is reduced by removing the heat of evaporation.
