Description

Schmelzflüsse für säurebeständige Schmelzfarben Durch Patent 536 528 sind Schmelzflüsse zur Herstellung keramischer Schmelzfarben unter Schutz gestellt, welche sich zum Dekorieren keramischer Waren, z. B. solchen aus Porzellan, eignen und gegen Säuren, wie sie beispielsweise zur Geschirreinigung Verwendung finden, sich ausgezeichnet beständig erweisen Diese Schmelzflüsse sind dadurch gekennzeichnet, daß sie neben basischen Bestandteilen, wie Alkalien, Erdalkalien, Bleioxyd u. dgl., und sauren Bestandteilen, wie Kieselsäure, Borsäure u. dgl., noch Eisenoxyd in die Säurebeständigkeit des Schmelzflusses bzw. der daraus hergestellten Schmelzfarben erhöhenden Mengen, vorzugsweise solchen von o,oj Molen und mehr, enthalten.Melt flows for acid-resistant enamel colors by patent 536 528 melt flows for the production of ceramic enamel colors are protected, which are suitable for decorating ceramic goods, e.g. B. those made of porcelain, are suitable and against acids, such as those used for washing dishes, prove to be extremely resistant These melt flows are characterized by that in addition to basic constituents such as alkalis, alkaline earths, lead oxide and the like, and acidic constituents such as silica, boric acid and the like, nor iron oxide in the Acid resistance of the melt flow or the enamel colors made from it increasing amounts, preferably those of o, oj moles and more.

Bei derartigen Schmelzflüssen können die Basen etwa in folgenden Grenzversätzen vorhanden sein: 0,35 his o,85 Pb0, 0,4.5 - o, i Alkali bzw. Erdaikali, 0,2 - 0,05 FeO, während neben i bis 2 Molen Kieselsäure noch z. B. o,i bis o,4. Mole Borsäure anwesend sein können.In the case of such melt flows, the bases can be present in the following limit offsets: 0.35 to 0.85 Pb0, 0,4.5 - o, i alkali or earth alkali, 0.2-0.05 FeO, while in addition to 1 to 2 moles of silica still z. B. o, i to o, 4. Moles of boric acid may be present.

Auf Grund eingehender Versuche hat es sich nun ergeben, daß der Gehalt der Schmelzflüsse an Borsäure weitgehend verringert oder auf Anwesenheit von Borsäure vollkommen verzichtet werden kann, da die Anwesenheit von Borsäure in gewissem Maße der säurebeständigmachenden Wirkung des Eisenoxyds entgegenzuwirken vermag und man Schmelzflösse, welche Eisenoxyd in die Säurebeständigkeit gewährleistenden Mengen enthalten, in einwandfreier Beschaffenheit auch ohne die Mitwirkung von Borsäure bzw. bei Anwesenheit ganz geringer Mengen von Borsäure erhalten kann.On the basis of detailed experiments it has now been found that the salary the melt flow of boric acid is largely reduced or due to the presence of boric acid can be completely dispensed with, since the presence of boric acid to some extent and one can counteract the acid-resistant effect of iron oxide Melt rafts, which iron oxide in the quantities guaranteeing acid resistance contained, in perfect condition even without the involvement of boric acid or in the presence of very small amounts of boric acid.

Ein diesen Bedingungen entsprechender Grenzversatz für einen Schmelzfluß gemäß Erfindung kann z. B. folgende Zusammensetzung haben. Ein derartiger Versatz vön der allgemeinen Formel . lä-Bt sich z. B. erschmelzen aus einer Mischung von i82,7 Teilen Bleioxyd, io,6Teilen Soda, 8 Teilen Eisenoxyd, 78,4 Teilen Kieselsäure.A boundary offset corresponding to these conditions for a melt flow according to the invention can, for. B. have the following composition. Such an offset from the general formula. z. B. melt from a mixture of i82.7 parts of lead oxide, io, 6 parts of soda, 8 parts of iron oxide, 78.4 parts of silica.

Auch derartige Schmelzflüsse eignen sich, wie gefunden wurde, in ausgezeichneter Weise zur Herstellung säurebeständiger Schmelzfarben.As has been found, melt flows of this type are also extremely suitable Way of making acid-resistant enamel colors.

Zwecks Herstellung von säurefesten Schmelzfarben, wie solche z. B. zum Dekorieren von keramischen Gegenständen Verwendung finden, kann man, z. B. derart verfahren; daB man. Versätze nach. der Erfindung mit für Schmelzfarbenherstellurig üblichen Farbkörpern, z. B. Metalloxyden, mischt, z. B. im Verhältnis q.o Teile Farbkörper auf Zoo Teile des Schmelzflusses. Durch entsprechende Bemessung des Anteils von Eisenoxyd lassen sich reine und leuchtende Farbtöne von Gelb, Grün, Schwarz, Braun u. dgl. erzielen.For the production of acid-resistant enamel colors, such as such. B. find use for decorating ceramic objects, you can, for. B. like this procedure; that one. Offsets after. of the invention for producing enamel colors usual color bodies, e.g. B. metal oxides, mixes, e.g. B. in the ratio q.o parts Color bodies on zoo parts of the Melt River. By measuring the proportion accordingly pure and luminous shades of yellow, green, black, Braun and the like.
