Description

Putz-, Polier- und Schleifmittel. Die Erfindung betrifft ein Putz-, Schleif-und Poliermittel, das aus dem bei der Herstellung von reinem Aluminiumoxyd aus Bauxit oder Ton in großen Mengen anfallenden Rotschlamm besteht. Dieser Rotschlamm enthält neben wesentlichen . Mengen von Eisenoxyd' und Silikaten noch kleine Mengen von kaustischen Alkalien oder Soda, die bei der Verwendung als Poliermittel eine reinigende Wirkung ausüben. Außerdem befindet sich im Rotschlamm noch eine geringe Menge des nicht aufgeschlossenen: Bauxits, der infolge seiner hohen spezifischen Härte die Schleiffähigkeit des Rohmaterials günstig beinflußt.Cleaning, polishing and abrasive preparations. The invention relates to a cleaning, Grinding and polishing agent obtained from the manufacture of pure aluminum oxide consists of bauxite or clay, which is produced in large quantities of red mud. This red mud contains besides essential. Quantities of iron oxide and silicates still small quantities of caustic alkalis or soda, which when used as a polishing agent have a cleansing effect. There is also a small amount in the red mud Amount of undigested: bauxite, which as a result of its high specific Hardness has a favorable influence on the ability of the raw material to be grinded.

Gemäß der Erfindung- wird der anfallende gewaschene" Rotschlamm durch Trocknen vom Wasser befreit; und da sich bei dieser-Gelegenheit der Alkaligehalt in Gestalt eines weißen Anfluges auf der Oberfläche der Masse teilweise auswittert, so -muß man durch sehr feines Mahlen und Sichten für die gleichmäßige Verteilung des- Alkalis in der Masse Sorge tragen.According to the invention, the resulting washed "red mud" is through Drying freed from water; and since on this occasion the alkali content partially weathers in the form of a white touch on the surface of the mass, so you have to go through very fine grinding and sifting for even distribution take care of the alkali in the mass.

Der fein gepulverte und gesichtete Rotschlämm bildet ohne weiteren Zusatz und ohne weitere Verarbeitung ein ganz vorzügliches Mittel für Putz=, Schleif- und Polierzwecke, insbesondere für Metalle, da die in der Masse enthaltenen Alkalien reinigend wirken, während die stets vorhandenen restlichen Bestandteile des Bauxits gleichzeitig eine schleifende .und polierende Wirkung haben: Man kann auch der Masse geringe -Mengen von Fetten oder Ölen zusetzen, die mit dem Alkali, gegebenenfalls beim Erwärmen, eine Seife bilden und dadurch kur Reinigung der zu putzenden Metalloberflächen beitragen. In ähnlicher Weise kann man natürlich auch Alkohol, Erdwachs oder ähnliche Stoffe mit dem trockenen Rotschlammpulver innig vermischen, wodurch eine Putzpaste entsteht.-Man hat schon Putzmittel usw. vorgeschlagen, die als hauptsächliche Bestandteile Eisenoxyd und Silikate und gegebenenfalls alkalisch- wirkende Bestandteile enthalten. Die Erfindung liegt also nicht in der Herstellung eines Putz-, Schleif- und Poliermittels aus diesen Stoffen, sondern in der Verwertung eines in großen Mengen gewonnenen wertlosen Abfallproduktes für Putz-, Schleif- und Polierzwecke, welches _ die eben erwähnten Bestandteile enthält.The finely powdered and sifted red mud forms easily Addition and without further processing a very excellent agent for plaster =, sanding and polishing purposes, especially for metals, since the alkalis contained in the mass have a cleaning effect, while the remaining components of the bauxite are always present have a grinding and polishing effect at the same time: one can also use the mass Add small amounts of fats or oils to the alkali, if necessary when warming up, form a soap and thereby quick cleaning of the metal surfaces to be cleaned contribute. In a similar way you can of course also use alcohol, earth wax or the like Mix the fabrics intimately with the dry red mud powder, creating a plaster paste - Cleaning agents etc. have already been proposed as the main components Contain iron oxide and silicates and possibly alkaline components. The invention does not therefore lie in the production of a cleaning, grinding and polishing agent from these substances, but in the recovery of one obtained in large quantities worthless waste product for cleaning, grinding and polishing purposes, which _ the contains mentioned ingredients.
