Description

Herstellung eines für Rostschutz-Ölanstriche geeigneten Pigmentes Um aus schwerspathaltigen Erzen ein für Rostschutz-Ölanstriche geeignetes Pigment zu erhalten, werden nach dem Verfahren des Patents 648 49 schwerspathaltige Erze nach Auflösen -des Schwerspats in einer- Natriumsulfatschmelze durch Umrühren oder durch Einblasen von Luft oxydiert und die Oxydationsprodukte durch Auslaugen des Natriumsulfats in Wasser in. feinste Mischung mit dem gebildeten Bariumsulfat gebracht. Es hat sich nun gezeigt, daß die Verwendung eines Salzes mit niedrigerem Schmelzpunkte an Stelle des Natriumsulfats vorteilhafter ist, da die Beständigkeit einzelner Metalloxyde durch die hohe Temperatur der Natriumsulfatschmelze beeinträchtigt wird.Preparing a composition suitable for rust proof oil paint pigment in order to obtain a material suitable for rust proof oil paint pigment of barytes protean ores, according to the process of the patent 648 49 heavy spar protean ores oxidized by dissolving -des Schwerspats in on the one sodium sulphate melt by stirring or by injection of air and the oxidation products are brought into a very fine mixture with the barium sulphate formed by leaching the sodium sulphate in water. It has now been shown that the use of a salt with a lower melting point instead of sodium sulfate is more advantageous, since the stability of individual metal oxides is impaired by the high temperature of the sodium sulfate melt.

Als Salze mit niedrigerem Schmelzpunkte kommen beispielsweise die Alkalinitrate in Betracht. Als Nitrate haben sie den weiteren Vorzug, daß sie ein Einblasen von Luft, wie es bei Verwendung seiner Natriumsulfatschmelze vorgesehen ist, entbehrlich machen, da bereits der Sauerstoff der Nitrate die Erze zu oxydieren vermag. Beispiel i oo g Blei-Zink-Eisen-Sulfide, die Schwerspat bzw. Bariumsulfat enthalten, werden in eine Schmelze von Zoo g Natronsalpeter @eingebracht und so lange erhitzt, als eine Gasent'wicklung stattfindet. Darauf wird- die Schmelze in Wasser eingetragen. Nach Auslaugen des Salzes und Trocknen des Rückstandes ergibt sieh ein rotbraunes Pulver, das sich als Rostschutzpigment eignet.Salts with a lower melting point are, for example, the Alkaline nitrates into consideration. As nitrates they have the further advantage that they are a Blowing in air as intended when using its sodium sulphate melt can be dispensed with, as the oxygen in the nitrates already oxidizes the ores able. Example i oo g lead-zinc-iron sulfides, the heavy spar or barium sulfate contained, are brought into a melt of Zoo g sodium nitrate @ and so on heated for a long time when a gas development takes place. Thereupon - the melt is in Water entered. After leaching out the salt and drying the residue gives see a reddish brown powder that works as a rust preventive pigment.
