Description

Die Verwendung von Aluminium zur Erzeugung hoher Temperaturen ist bekannt. So wird z. B. Aluminium mit der äquivalenten Menge Eisenoxyd zur Reaktion gebracht, wobei als Reaktionsprodukte Aluminiumoxyd und flüssiges Eisen entstehen. Weiterhin ist vorgeschlagen worden, Aluminium mit der äquivalenten Menge Schwefel zu mischen und durch Zusammenschmelzen mit diesem unentmischbar zu machen. Die durch Entzündung eines solchen Gemisches eingeleitete Reaktion ist ebensowenig wie die zuerst angeführte auf die Mitwirkung des Luftsauerstoffs angewiesen.The use of aluminum to generate high temperatures is known. So is z. B. brought aluminum with the equivalent amount of iron oxide to the reaction, with aluminum oxide and liquid iron are formed as reaction products. Furthermore is It has been proposed to mix aluminum with the equivalent amount of sulfur and to make it immiscible by merging with it. The one from inflammation The reaction initiated by such a mixture is as little as the first mentioned dependent on the cooperation of the oxygen in the air.

Die Verbrennung von fein verteiltem Aluminium lediglich mit Hilfe des Luftsauerstoffs bietet jedoch wegen der entstehenden Schlacke sowie auch wegen der Regelbarkeit der Wärmeentwicklung, beispielsweise zum Löten, Verzinnen und Schweißen, aber auch zur Verwendung für beliebige andere Heizzwecke, besondere Vorteile.The combustion of finely divided aluminum only with the help of atmospheric oxygen offers because of the resulting slag as well as because of the controllability the heat development, for example for soldering, tinning and welding, but also for use for any other heating purpose, particular advantages.

Schwierigkeiten macht hierbei die schwere Entzündlichkeit des Aluminiums besonders dann, wenn die Wärmeentziehung durch die zu heizende Vorrichtung sehr groß ist und die einzelnen Aluminiumteilchen dicht aufeinanderliegen. Um diese Schwierigkeiten zu beseitigen, hat man vorgeschlagen, dem AIuminium einen Teil des zur Verbrennung benötigten Sauerstoffs in chemisch gebundener Form beizumengen. .Ein solches Gemenge ist demnach ein durch überschüssiges Aluminium abgeschwächter Sprengstoff, dessen sprengstoffartige Natur sich z. B. dann wieder zeigt, wenn durch teilweises Entmischen an einer Stelle des Gemenges eine Anreicherung des Sauerstoffträgers eingetreten ist. Die Herstellung, Lagerung und auch der Gebrauch eines solchen Heizstoffs ist also mit Gefahr verbunden. Hierzu tritt noch die Gefahr der Selbstentzündung, wenn man, wie ebenfalls vorgeschlagen wurde, als Sauerstoff träger das durch Feuchtigkeit unter Wärmeentwicklung zersetzliche Baryumsuperoxyd anwendet.Difficulties are made here by the difficult flammability of aluminum when the heat extraction by the device to be heated is very large and the individual aluminum particles lie close together. To these difficulties too Eliminate, it has been suggested that the aluminum part of what is needed for combustion Add oxygen in chemically bound form. . Such a mixture is accordingly an explosive weakened by excess aluminum, its explosive-like one Nature z. B. then shows again when an enrichment of the by partial segregation at one point of the mixture Oxygen carrier has occurred. The manufacture, storage and also use such a fuel is therefore associated with danger. In addition there is the danger of Auto-ignition if, as has also been suggested, the oxygen-carrier is that uses barium superoxide which is decomposable by moisture with the development of heat.

Gegenstand der Erfindung ist ein aus Aluminiumpulver bestehender und zum Verbrennen ausschließlich mit Hilfe des Luftsauerstoffs bestimmter Heizstoff, der leicht entzündlich ist, gefahrlos hergestellt und angewendet werden kann und sich durch Lagerbeständigkeit auszeichnet.The invention relates to an aluminum powder and to be burned Exclusively with the help of the oxygen in the air, certain heating fuel, which is highly flammable is, can be manufactured and used safely and has a long shelf life excels.

Es hat sich gezeigt, daß Aluminiumpulver dadurch leicht entzündlich gemacht werden kann, daß man ihm eine geringe Menge Schwefel in elementarer oder chemisch gebundener Form beimengt. So bewirkt ein Schwefelgehalt von r bis 5 Prozent eine bedeutende Steigerung der Entzündlichkeit, wie sie für alle in Frage kommenden Verwendungszwecke genügt. Neben der gefahrlosen Herstellung, Lagerung und Anwendung bietet ein solcher Heizstoff auch den Vorteil, daß er ohne Gefahr in bekannter Weise durch Pressen unter beliebigem Druck in Formen brikettiert werden kann.It has been shown that this makes aluminum powders easily flammable can that you give him a small amount of sulfur in elemental or chemically bound Form added. For example, a sulfur content of r to 5 percent has a significant effect Increase in flammability as they are for all possible uses enough. In addition to the safe production, storage and use, such Heating fuel also has the advantage that it can be produced in a known manner by pressing under any risk Print can be briquetted into molds.
