Description

Herstellung von mit Wasser jäh und vollständig abbrennenden Phosphiden in Form von Preßlingen Es ist bekannt, Phosphide in Form von Preßlingen in der Weise herzustellen, da:ß man ein unter Verwendung von Bindemitteln, wie Dextrin, Salmiak, Kolophonium, zu Blökken gepreßtes Gemisch von Metalloxyden mit amorphem Phosphor durch Erhitzen umsetzt. Der Vorteil des Verfahrens besteht darin, daß das Phosphormetall nicht pulverförmig, sondern stückig anfällt und sich so leichter verarbeiten läßt. In bezug auf die Reaktionsfähigkeit dieses Erzeugnisses, insbesondere hinsichtlich der Geschwindigkeit und Vollständigkeit des Reaktionsverlaufes bei der Zersetzung dieser Blöcke durch Wasser, ist jedoch ein Unterschied gegenüber dem aus stückigem Ausgangsmaterial, beispielsweise gebrochenem Kalk, hergestellten Phosphid nicht festzustellen. Typisch für diese in verschiedener Weise hergestellten Stoffe ist aber die Tatsache, daß nach Wasserzutritt eine zunächst heftige Gasentbindung einsetzt, die jedoch bald nachläßt, so daß ein. erheblicher Anteil (5o0/1o und mehr) Phosphorwasserstoff für die praktische Verwertung ausfällt.Production of phosphides that burn off suddenly and completely with water in the form of compacts It is known to use phosphides in the form of compacts in the manner to produce, that: ß one using binders such as dextrin, salmiac, Colophony, a mixture of metal oxides pressed into blocks with amorphous phosphorus converted by heating. The advantage of the process is that the phosphorus metal not in powder form, but in chunks and so easier to process. With regard to the responsiveness of this product, especially with regard to the speed and completeness of the course of the reaction during decomposition these blocks through water, however, is a difference compared to that from lumpy Starting material, for example broken lime, does not produce phosphide ascertain. Typical of these substances manufactured in various ways is but the fact that after the admission of water an initially violent release of gas begins, which soon wears off, so that a. considerable proportion (50/10 and more) of phosphine for practical recycling fails.

Bei der Verwendung von Phosphiden zur Markierung des Standortes von Torpedos kommt es nun darauf an, daß der Phosphorwasserstoff möglichst vollständig innerhalb etwa 3o Minuten nach dem Schuß entbunden wird; die später frei werdende Menge geht nutzlos verloren. Andererseits ist aber auch der während der ersten Laufzeit, etwa bis zur zehnten Minute nach dem Abschuß des Torpedos, entwickelte Phosphorwasserstoff völlig verloren.When using phosphides to mark the location of For torpedoes it is now important that the phosphine is as complete as possible is delivered within about 30 minutes of the shot; the one that will become free later Lot is wasted uselessly. On the other hand, it is also the case during the first term Until about the tenth minute after the torpedo was launched, hydrogen phosphide evolved completely lost.

Erfindungsgemäß kann man Phosphide in Form von Preßlingen, die den sich hieraus ergebenden Anforderungen entsprechen, in der Weise erzeugen, daß man fertig gebildetes Phosphid, z. B. Phosphorcalcium, gepulvert und gegebenenfalls unter Zuhilfenahme von Zusatzstoffen, die die rasche Gasentbindung fördern, zu Preßlingen verarbeitet und diese nach dem Verfahren des Patents q.6o 323 mit wasserlöslichen bzw. wasserdurchlässigen Hüllen umkleidet.According to the invention you can phosphides in the form of compacts that the correspond to the resulting requirements in such a way that one finished phosphide, e.g. B. phosphorus calcium, powdered and optionally with the aid of additives that promote the rapid release of gas, to compacts processed and these according to the method of the patent q.6o 323 with water-soluble or water-permeable covers.

Als Zusatzstoffe bei der Herstellung der Preßlinge kommen die Reaktion mit Wasser und den raschen Zerfall der Preßlinge fördernde Stoffe in trockenem Zustande, z. B. Oxalsäure, Natriumbisulfit, Alkalihydroxyd usw., in Frage. Ausführungsbeispiel Stückiges Phosphorcalcium wird in einer geschlossenen Kugelmühle unter Zusatz von 5 Teilen Natriumbisulfit auf zoo Teile Phosphorca.lcium vermahlen. Das entstandene pulverförmige Gemisch wird mittels einer Tablettenpresse zu etwa zamm im Durchschnitt messenden Kugeln verpreßt. Diese Kugeln werden dann gemäß dem Verfahren des Patents 460 323 in einem Drehofen mit einer Schmelze von Natriumbichromat überzogen und entsprechen in diesem Zustande den oben beschriebenen Forderungen an ein Leuchtmittel für die Kennzeichnung des Standortts, vön '@`orpeä`ö`, As additives in the production of the compacts, the reaction with water and substances promoting the rapid disintegration of the compacts come in a dry state, e.g. B. oxalic acid, sodium bisulfite, alkali hydroxide, etc., in question. Exemplary embodiment Lumpy phosphorus calcium is ground in a closed ball mill with the addition of 5 parts of sodium bisulfite to give zoo parts of phosphorus calcium. The resulting powdery mixture is pressed by means of a tablet press into spheres measuring approximately together on the average. These balls are then coated with a melt of sodium dichromate in a rotary kiln in accordance with the method of patent 460 323 and in this state meet the above-described requirements for a Illuminants for the identification of the Location, vön '@ `orpeä`ö`,
