Description

Verfahren zur Herstellung farbiger Zemente aus geschmolzenem und gemahlenem Magnesiumoxyd oder Magnesit Es ist bekannt, farbige Zemente durch Beimischung von Mineralfarben u. dgl. zu der zementartigen Grundsuhstanz herzustellen.Process for the production of colored cements from molten and ground Magnesium oxide or magnesite It is known to make colored cements by admixing To produce mineral paints and the like for the cementitious base.

Diese Herstellung farbiger Zemente, bei der ein bestimmter Farbton durch .einfache Mischung erzielt wird, bedingt verschiedene Nachteile. Man ist zur Erzielung satter Farbtöne genötigt, der Grundsubstanz .einen sehr hohen Prozentsatz des Farbpulvers beizumischen, wodurch die spezifische Eigenart der zementartigen Grundsubstanz ungünstig beeinflußt, unter Umständen sogar aufgehoben wird. Außerdem ist es auf diese Weise nicht möglich, licht- und wetterbeständige Farbtöne herzustellen. Auch werden solche Farben zumeist durch die chemischen Verunreinigungen der Atmosphäre beeinträchtigt.This production of colored cements in which a certain shade is achieved by .simple mixing, causes various disadvantages. One is to Achieving rich color tones required, the basic substance. A very high percentage to mix in the color powder, creating the specific character of the cementitious Basic substance is adversely affected, possibly even canceled. aside from that it is not possible in this way to produce lightfast and weather-resistant colors. Such colors are mostly caused by the chemical pollution of the atmosphere impaired.

Zur Vermeidung dieser Nachteile wird nach dem neuen Verfahren wie folgt verfahren;: Magnesiumoxyd oder Magnesit wird gemeinsam mit einem färbenden Metalloxyd geschmolzen, wobei sich beide Stoffe miteinander chemisch verbinden, wodurch ein durch gewöhnliche Einflüsse unzerstörbarer Farbkörper entsteht. Als Metalloxyde kommen z. B. Kobalt- und Nickeloxyd in Frage. Zur Herstellung bestimmter Farbnuancen kann man aber auch Gemische von Metalloxyden anwenden. Ferner kann man den Farbton dadurch variieren, daß man z. B. zu einer Magnesium-Kobaltoxyd-iMischungtA.luminiumoxyd zufügt, wodurch man ein rotstichiges Blau oder Violett erhält.To avoid these disadvantages, according to the new method, such as Proceed as follows ;: Magnesium oxide or magnesite is used together with a coloring Metal oxide melted, whereby both substances chemically combine with each other, whereby a body of color is created that is indestructible by ordinary influences. as Metal oxides come e.g. B. cobalt and nickel oxide in question. For the production of certain Color nuances can also be used as mixtures of metal oxides. Furthermore, one can vary the hue by z. B. to a magnesium-cobalt oxide mixture tA.luminiumoxyd adds, which gives a reddish blue or purple.

Man kann auf diese Weise sowohl lebhafte als auch abgetönte Farben von großer Mannigfaltigkeit erhalten.In this way, you can have both vivid and tinted colors preserved of great diversity.

Die Anwendung der nach dem neuen Verfahren hergestellten farbigen Zemente erstreckt sich auf alle Gebiete der Kunst und des Kunstgewerbes, wie z. B. zur Herstellung von Plastiken, in der Freskomalerei und ähnlichen Anwendungsgebieten, wo ästhetische Wirkungen erzielt werden sollen.The application of the colored produced by the new process Cement extends to all areas of the arts and crafts, such as B. for the production of sculptures, in fresco painting and similar areas of application, where aesthetic effects are to be achieved.
