Description
Verfahren zum Glasieren von Zementwaren,' besonders Asbestzementschiefer u. dgl. Es ist schon mehrfach vorgeschlagen worden, Zementwaren aller Art zu glasieren, teils um sie widerstandsfähiger zu machen, teüls zu Verzierungszwecken. So hat man auf Zementgegenstände, die in der Masse besondere Flußmittel enthielten, Glasflüsse aufgetragen und eingebrannt. Anderseits sind auch Platten aus Asbestzementschiefer mit Glasuren versehen worden. Doch haben sich diese Erzeugnisse anscheinend nicht bewährt, weil das Einbrennen der Glasur zu hohe Temperaturen erfordert, bei denen die Platten brüchig werden.A method of glazing of cement products, particulary u 'asbestos cement slate. Like. It has already been proposed several times to glaze cement goods of all kinds, partly to them more resistant to ma chen, teüls to decorating purposes. For example, glass fluxes were applied and burned onto cement objects that contained special fluxes. On the other hand, plates made of asbestos-cement slate have also been provided with glazes. However, these products have apparently not proven themselves because baking the glaze requires temperatures that are too high, at which the plates become brittle.
Nach der Erfindung sollen solche Platten, in erster Linie Asbestzenentplatten, dadurch mit einer dauerhaften Glasur versehen werden, die verhältnismäßig niedrige Temperaturenerfordert, daß man die Platten, zweckmäßig schon vor ihrer völligen Erhärtung, mit solchen Flußmitteln überzieht oder oberflächlich tränkt, die mit den Bestandteilen des Zements oder Asbestes, also Tonerde-, Kalk- oder Magnesiasilikaten, einen leichten, Schmelzfluß bilden, so daß also die Glasur erst durch eine im Schmelzfluß entstehende Vereinigung. der Zementbestandteile und der aufgebrachten Stoffe gebildet wird. Solche Stoffe sind z. B. Fluorid:e, in erster Linie Alkalifluoride, die als wäßrige Lösung aufgebracht werden können. Bei dem Brande und der in: ihm, teilweise auch schon vorher. erfolgenden chemischen Reaktion, z. B. mit den Kalkbestandteilen des Zements, entstehen unlösliche Fluorverbindungen, die im Schmelzfluß einen wetterfesten, in der Oberfläche verankerten: Überzug bilden.. Die nach dem Trocknen der aufgetragenen Schicht erfolgende Erhitzung kann entweder durch Brennen der Gegenstände in: einem geeigneten Ofen oder durch Bestreichen derselben mit einer Gebläseflamme o. dgl. bewirkt werden.According to the invention, such panels, primarily asbestos panels, as a result, they are provided with a permanent glaze, the relatively low one Temperatures require that the plates, expediently before their complete Hardening, coated with such fluxes or superficially impregnated with the components of cement or asbestos, i.e. alumina, lime or magnesia silicates, Form a light, melt flow, so that the glaze only through one in the melt flow emerging association. of the cement components and the applied substances will. Such substances are z. B. Fluoride: e, primarily alkali fluorides, which are used as aqueous solution can be applied. In the fire and in: him, partly even before. chemical reaction taking place, e.g. B. with the lime components of the cement, insoluble fluorine compounds are formed, which form a weatherproof, anchored in the surface: form coating .. After drying the applied Heating can take place either by burning the objects in: a suitable oven or by brushing the same with a fan flame or the like. be effected.
Selbstverständlich können der überzugsschicht beliebige Mineralfarben u. dgl. zugemischt werden.Of course, any mineral colors can be used for the coating layer and the like.
