Description

Verfahren zur Herstellung von Gemischen aus 1Vlineralstoffen und Leichtmetallpulver Zur HersteIhmg poröser Baustoffe benutzt man u. a. ein Verfahren, bei dem einem Gemisch von Zement mit Sand, Kalkschiefer oder ähnlichen Stoffen fein verteiltes Aluminium zugefügt wird. Das Aluminiumpulver wird nach Anfeuchtung dieser Betonmischung durch den beim Abbinden frei werdenden Kalk unter Gasentwicklung zersetzt. Die entstehenden Gasbläschen lockern, den. Beton schaumartig auf. Die Herstellung des Aluminium- ioder ähnlicher Leichtmetallpulver ist, da man es aus dünn gewalzten Folian durch Zerkleinerung in Pochwexken oder auf ähnliche Art .erzeugen muB, um die erforderliche Feinheit zu erreichen, sehr langwierig und kostspielig. Zweck des vorliegenden Verfahrens ist, :die Herstellung des Pulvers in bequemerer Weise und zu geringeren Gestehungskosten zu ermöglichen und dabei das für die Zubereitung des Schaumbetons benötigte Sand-Metallpulver-G-emisch in einem Arbeitsgange zu gewinnen.Process for the production of mixtures of 1lineral materials and light metal powder For the manufacture of porous building materials one uses, among other things. a process in which one Mixture of cement with sand, limestone shale or similar materials, finely divided Aluminum is added. The aluminum powder is after moistening this concrete mixture decomposed by the lime released during the setting process with evolution of gas. The emerging Loosen gas bubbles, the. Foam-like concrete. The manufacture of the aluminum ior similar light metal powder, as it is made from thinly rolled folian Crushing in Pochwexken or in a similar way To achieve delicacy is very tedious and costly. Purpose of the present proceedings is: the production of the powder in a more convenient way and at a lower cost to enable and thereby the required for the preparation of the foam concrete sand-metal powder-G-emic to win in one operation.

Auf Grund eingehender Versuche ist gefunden worden, daß die Hexbeiführung der feinen Verteilung des Metalls unmittelbar ausgehend vom geschmolzenen Zustande dadurch erfolgen kann, daß man das Metall in die durch. Rührei oder auf andere geeignete Weise bewegte und durcheinanderge:.wirbelte Massee des Sandes oder Kalkschiefers einfließen läßt, worauf :die Umwixbelung das Ganzen so lange fortgesetzt wird, his das Metall :erstarrt ist. Man hat bereits vorgeschlagen, zur Herstellung von Metallpulver beliebige anorganische Stoffe mit geschmolzenem Metall zu verrühren (vgl. Patent 390 969). Diese Stoffe werden jedoch später zwecks Isolierung des Metallpulvers durch Auflösen u. a. wieder aus der Mischung entfernt. Die voräqgeade Erfindung ist dagegen darauf abgestellt, Mischungen, von LeiichtmetaRpulver mit solchen mineralischen Stoffex. herzustellen, wie sie zum Aufbau von Gasbeton dienen, aus .denen das Leichtmetallpulver nicht isoliert wird. Der Stand wird zweckmäßig vorn dem Einbringen des Metalls erhitzt, damiit die Erstarrung des Metalls so lange vemägert wird, bis dieses infolge der Bewegung und durch Mischung mit dem Sand in feinst verteilte Form übergeführt ist. Die Korngröße des Metallpulvers kann durch Änderung der Rührgeschwindigkeit und der Abkühlungsdauer beliebig geregelt werden.On the basis of extensive experiments it has been found that the hexaducting of the fine distribution of the metal can take place directly from the molten state by inserting the metal into the through. Scrambled eggs or in some other suitable way agitated and mixed-up mass of sand or limestone slate flows in, whereupon the agitation is continued until the metal has solidified. It has already been proposed to stir any inorganic substances with molten metal for the production of metal powder (cf. Patent 390 969). However, these substances are later removed from the mixture again for the purpose of isolating the metal powder by dissolving, among other things. The previous invention, on the other hand, is geared towards using mixtures of light metal powder with such mineral substances. produce the way they are used to build aerated concrete, from .denen the light metal powder is not isolated. The stand is expediently heated before the metal is introduced, so that the solidification of the metal is aggravated until it is converted into finely distributed form as a result of the movement and by mixing with the sand. The grain size of the metal powder can be regulated as required by changing the stirring speed and the cooling time.

Als Ausgangsstoff zur Herstellung des Metallpulvers kann außer dem Reinaluminium des Handels und weniger reinen Aluminiumsorten auch jede beliebige Aluminiumlegierung oder auch Magnesium und dessen Legierungen benutzt werden.As a starting material for the production of the metal powder can also Commercial pure aluminum and any less pure aluminum types, too Aluminum alloy or magnesium and its alloys are used.
