Description

Glasurverfahren. Es ist bekannt, daß man auf Tonwaren, Porzellan, Steingut und dgl. dadurch Glasuren erhalten kann, daß man wasserlösliche Alkalisilikate aufträgt, die sich dann unter der Einwirkung der Kohlensäure aus der Luft oder künstlich zugeführter Kohlensäure unter Abscheidung von Kieselsäure zersetzen und eine glänzende, zusammenhängende Glasur bilden. Diese lackähnlichen Glasuren haben den CTbelstan:d, daß leicht Risse eintreten und ein Abspringen erfolgt, eine Folge der eigenartigen :Ausdehnungsverhältnisse der Kieselsäure bei Temperaturveränderungen. Bei der bisherigen Glasierung mit Alkalisilikaten bestand nur ein mechanisches Anhaften an den Untergründen, wodurch die angeführte Trennung von der Unterlage hervorgerufen wurde.Glaze process. It is known that pottery, porcelain, Earthenware and the like. Glazes can be obtained by using water-soluble alkali silicates applies, which is then under the action of carbonic acid from the air or artificially the added carbon dioxide decompose with the separation of silica and a shiny, form coherent glaze. These lacquer-like glazes have the CTbelstan: d, that cracks easily appear and spring off, a consequence of the peculiar ones : Expansion ratios of the silica with temperature changes. With the previous one Glazing with alkali silicates was only a mechanical adhesion to the substrates, whereby the mentioned separation from the document was caused.

Das vorliegende Verfahren besteht darin, claß man Alkalisilikate auf plastische Massen aus Fluorsilikaten und Ton aufträgt und auf die überzogenen Gegenstände, gegebenenfalls nach dem Trocknen, entweder die Kohlensäure der Luft oder künstlich zugeführte Kohlensäure und kohlensäurehaltige Gasmischungen einwirken lädt. Die Silikate und die verbindungsfähige Kieselsäure verbinden sich chemisch mit den aus Fluorsilikaten und Ton bestehenden Grundkörpern. Infolgedessen tritt ein festes Haften des Überzuges auf der Unterlage ein, .und das Abspringen und Rissigwerden unterbleibt oder wird zum mindesten verringert. Der Zusatz der Kieselsäurealkalien kann vor oder nach dem Formen oder vor oder nach dem Trocknen der Gegenstände stattfinden. Den Alkalisilikaten können Farben, Farbstoffe oder :sonstige Zusätze, welche die Oberfläche verändern, wie z. B. Zinkstaub, Aluminiumstaub, Graphit, Kohle u. d'-,I., zugesetzt werden.The present process consists in classifying alkali silicates applies plastic masses of fluorosilicates and clay and on the coated objects, if necessary after drying, either the carbonic acid of the air or artificially added carbon dioxide and carbonated gas mixtures act loads. the Silicates and the bondable silica combine chemically with the Fluorosilicates and clay existing basic bodies. As a result, a solid occurs Adhesion of the coating to the substrate, and the chipping and cracking does not occur or is at least reduced. The addition of silicic acid alkalis can take place before or after the molding or before or after the drying of the objects. The alkali silicates can contain colors, dyes or: other additives which the Change the surface, such as B. zinc dust, aluminum dust, graphite, coal and d '-, I., can be added.

Das Verfahren ist besonders für die Masse nach Patent 4o65 i 7, nach welchem man fluorwasserstoffsaure Verbindungen. mit Salzsäure oder Schwefelsäurebehandelt und dieMischung mit 1lagnesiumsilikaten und Aluminiumsilikaten, z. B. Speckstein, Talkum, Asbest u. dgl., vermischt, bestimmt.The method is particularly suitable for the compound according to patent 4o65 i 7, according to which one one hydrofluoric acid compounds. treated with hydrochloric acid or sulfuric acid and the mixture with magnesium silicates and aluminum silicates, e.g. B. soapstone, Talc, asbestos and the like, mixed, determined.

Die Menge des Alkalisilikates und die Konzentration der Lösungen richtet sich nach der gewünschten Dicke der Schicht.The amount of alkali silicate and the concentration of the solutions are determined depending on the desired thickness of the layer.

Man kann Alaun, Phosphorsäure und auch Ole zugeben.You can add alum, phosphoric acid and also oils.
