Description

Verfahren zur Herstellung einer Beize für Elektronmetall. Es ist bereits bekannt, die unter dem Namen Elektronmetall bekannte Aluminium-Magnesium-Legierung durch eine oxydierende Beize mit einer Schutzschicht zu versehen, um das Metall beständig gegen Einflüsse der Luft und des Wassers zu machen.Process for making a pickle for electron metal. It is already known, the aluminum-magnesium alloy known under the name electron metal to provide a protective layer to the metal by means of an oxidizing stain to make it resistant to the effects of air and water.

Die Erfindung hat nun die Herstellung einer besonderen Beize zum Gegenstand, die nach Angaben des Erfinders die bisherigen oxydierenden Beizen an Einfachheit der Behandlung und Wirksamkeit übertrifft. Es wird gemäß der Erfindung eine Beize verwendet, deren unterscheidender Bestandteil Natriumperborat ist. Die Beize besteht aus Salpetersäure, destilliertem Wasser, Natriumchromat, Kalisalpeter und Natriumperbörat. Hiervon sind Salpetersäure und Chromar schon früher als Bestandteile -der Beize für Flektronmetall verwendet worden.The subject of the invention is the production of a special stain, which, according to the inventor, the previous oxidizing stains in terms of simplicity outperforms the treatment and effectiveness. It becomes a stain according to the invention used, the distinguishing component of which is sodium perborate. The stain persists from nitric acid, distilled water, sodium chromate, potassium nitrate and sodium perborate. Of these, nitric acid and chromar are already used as components of the stain has been used for flectron metal.

Man mischt zweckmäßigerweise 25 kg chemisch reine Salpetersäure spez. Gewicht 1,2, 25 g .chemisch reines -Natrium chromicum und 5oo g -technisch reinen Kalisalpeter unter Zusatz von 25 kg destilliertem Wasser, läßt diese Lösung etwa eine halbe Stunde bis zur vollständigen Auflösung der einzelnen Bestandteile stehen und setzt ihr dann 25o g technisch reines Natriumperborat zu. Damit ist die Beize fertig.It is advisable to mix 25 kg of chemically pure nitric acid spec. Weight 1.2, 25 g of chemically pure sodium chromicum and 5oo g of technically pure Potash nitrate with the addition of 25 kg of distilled water, this solution leaves about Stand for half an hour until the individual components have completely dissolved and then add 250 g of technically pure sodium perborate to it. That’s the stain done.

Das Elektromnetall wird kurz in die Beize eingetaucht, in kaltem Wasser abgespült, darauf kurz in kochendes Wasser getaucht und schließlich 'mit Sägespänen o. dgl. trockengerieben. Die Oberfläche des Elektrons ist nunmehr glänzend silberweiß, ähnlich der des Aluminiums und vollständig luftbeständig. Die Beize schützt aber nicht nur die Oberfläche des Elektrons, sondern sie ist auch in das Metall eingedrungen und hat dieses verändert, so daß das Elektron nach Angaben des Erfinders selbst bei mechanischer Beanspruchung seiner. Oberfläche und bei der dadurch bedingten Abnutzung luftbeständig bleibt, selbstverständlich solange letztere nicht das normale Maß überschreitet.The electric metal is briefly immersed in the stain in cold water rinsed, then briefly dipped in boiling water and finally 'with sawdust or the like rubbed dry. The surface of the electron is now shiny silver-white, similar to that of aluminum and completely air-resistant. But the stain protects not only the surface of the electron, but it has also penetrated the metal and has changed this so that the electron according to the inventor himself with mechanical stress on its. Surface and the resulting Wear and tear remains air-resistant, of course, as long as the latter is not the normal Exceeds measure.

Das Mengenverhältnis der einzelnen Bestandteile der Beize zueinander kann innerhalb gewisser Grenzen verändert werden, j e nachdem man eine schwache oder eine starke Beize herstellen will.The proportions of the individual components of the stain to one another can be changed within certain limits, according to a weak one or want to make a strong stain.
