Abstract

The invention relates to a mixture of materials for generating gases in a gas generator. The mixture of materials consists of a mixture of 70 to 90 per cent by weight of sodium azide (NaN3), zero to 30 per cent by weight of a binary oxide material and zero to 30 per cent by weight of an activator material. The mixture of materials has the advantage that the residue remaining after burning off does not contain any elemental sodium and therefore does not react with water.

Description

Stoffgemisch zur GaserzeugungMixture of substances for gas generation

Die Erfindung bezieht sich auf ein Stoffgemisch zur Erzeugung von Gasen bestimmter Mengen und bestimmten Reinheitsgrades durch Reaktion von Komponenten festen Aggregatzustandes, wobei das Stoffgemisch nach Patent ... (Patentanmeldung P 32 38 468.3) aus einer Mischung von Natriumazid (NaN3) und Reaktionsstoffen besteht.The invention relates to a mixture of substances for the production of Gases of certain quantities and certain degrees of purity through reaction of components solid state of aggregation, the mixture of substances according to patent ... (patent application P 32 38 468.3) consists of a mixture of sodium azide (NaN3) and reactants.

Im Hauptpatent (Hauptpatentanmeldung) ist ein.Stoffgemisch zur Gaserzeugung mit einem Gasgenerator beschrieben, das eine Stickstofferzeugung mit hoher Ausbeute und.mit hohem Reinheitsgrad ermöglicht. Das dort vorgeschlagene Stoffgemisch besteht aus Natriumazid (NaN3), dessen Stickstoffanteil (N) nach Zünden eines Wärmeprozesses durch Reaktion mit einem Reaktionsstoff freigesetzt wird. Die Erzeugungsrate hängt dabei nach dem ZUnden von der Abbrandgeschwindigkeit ab, die durch Veränderung der Mischungskonzentration beeinflußt werden kann. Zum besseren Abführen des erzeugten Gases (Stickstoff) wird das S-toffgemisch in Granulatform benutzt, wobei jedes Granulatkorn aus dem Stoffgemisch oder das Stoffgemisch aus Granulatkörnern jeweils reiner Stoffe hergestellt werden kann. Mit diesem Stoffgemisch ist es, wie bereits erwähnt, möglich, eine hohe Ausbeute zu erzielen, aber es ist unbefriedigend, daß der Rückstand elementares Natrium enthält, das in Kontakt mit Wasser reagiert und zu unerwünschter Wasserstofferzeugung führt.In the main patent (main patent application) there is a mixture of substances for generating gas described with a gas generator that generates nitrogen with high yield and.with a high degree of purity. The mixture of substances proposed there exists from sodium azide (NaN3), its nitrogen content (N) after ignition of a heating process is released by reaction with a reactant. The generation rate depends after the ignition of the burn rate, which is determined by changing the Mixture concentration can be influenced. For better discharge of the generated Gas (nitrogen), the mixture of substances is used in granulate form, with each granulate grain from the mixture of substances or the mixture of granules of pure substances can be produced. With this mixture of substances it is possible, as already mentioned, obtain a high yield, but it is unsatisfactory that the residue is elemental Contains sodium, which reacts in contact with water and leads to undesired hydrogen production leads.

Die Erfindung geht von der Lösung des Hauptpatentes (Hauptpatentanmeldung) aus mit der Aufgabe, ein Stoffgemisch zur Gaserzeugung vorzusehen, dessen Rückstand nicht mit Wasser reagiert. Gemäß der Erfindung ist diese Aufgabe dadurch gelöst, daß das Stoffgemisch aus einer Zusammensetzung von 70 bis 90 Gewichtsprozenten Natriumazid (NaN3), null bis 30 Gewichtsprozenten eines binären Oxidstoffes und eines Aktivatorstoffes von null bis 30 Gewichtsprozenten besteht.The invention is based on the solution of the main patent (main patent application) with the task of providing a mixture of substances for gas generation, its residue does not react with water. According to the invention, this object is achieved by that the mixture of substances consists of a composition of 70 to 90 percent by weight sodium azide (NaN3), zero to 30 percent by weight of a binary oxide substance and an activator substance from zero to 30 percent by weight.

Das erfindungsgemäße Stoffgemisch hat den Vorteil, daß der nach dem Abbrennen verbleibende Rückstand kein elementares Natrium mehr enthält und daher in Verbindung mit Wasser nicht mehr reagiert. Für den binären Oxidstoff kann dabei Bortrioxid (B203) oder Siliziumdioxid (SiO2) benutzt werden, während für den Aktivator Schwefel (S) oder Phosphor (P) eingesetzt werden kann. Der Sauerstoff des jeweils verwendeten binären Oxidstoffes sorgt beim Abbrennen für die Bindung des Natriums 9 so daß im Rückstand kein elementares Natrium auftritt. Die Ausbeute des erzeugbaren Stickstoffes ist bei diesem Stoffgemisch im Vergleich zum Hauptpatent (Hauptpatentanmeldung) zwar etwas geringer, dafür ist aber der Rückstand frei von elementarem Natrium. Die Aktivatorstoffe Schwefel (S) oder Phosphor (P) werden zur Beeinflussung der Abbrandgeschwindigkeit mit der dazu jeweils erforderlichen Konzentration zugefügt. Diese Stoffe tragen zur Natriumbindung ebenfalls bei.The mixture of substances according to the invention has the advantage that the after Burning off remaining residue no longer contains any elemental sodium and therefore no longer reacts in contact with water. For the binary oxide, it can Boron trioxide (B203) or silicon dioxide (SiO2) can be used while for the activator Sulfur (S) or phosphorus (P) can be used. The oxygen of each The binary oxide used ensures that the sodium is bound when it burns off 9 so that no elemental sodium occurs in the residue. The yield of the producible In this mixture of substances, nitrogen is in comparison to the main patent (main patent application) a little less, but the residue is free of elemental sodium. The activators sulfur (S) or phosphorus (P) are used to influence the Burn rate added with the concentration required in each case. These substances also contribute to the binding of sodium.
