Patentirt im Deutschen Reiche vom 2. Juni igoo ab.Patented igoo in the German Empire from June 2nd.
Vorliegende Erfindung bezieht sich auf ein Verfahren zur Herstellung von dunklen Portlandcementen dadurch, dafs man als Zusatz zu den Rohmaterialien Chlorkalk benutzt.The present invention relates to a method for producing dark portland cements by using chlorinated lime as an additive to the raw materials.
Diese Beimengung, welche die Farbe des Cementes beeinflufst, übt auf die sonstigen Eigenschaften desselben keinen Einflufs aus. Die Festigkeit und die Eigenschaft der Volumenbeständigkeit sind in so hohem Mafse vorhanden wie bei dem gewöhnlichen Cement, und entspricht das neue Product vollkommen den Anforderungen der deutschen Normen.This admixture, which affects the color of the cement, affects the others Properties of the same have no influence. The strength and the property of volume stability are present in as high a measure as in the ordinary cement, and the new product corresponds perfectly to the Requirements of the German standards.
Der besondere Vortheil, den man durch das vorliegende Verfahren erzielt, ist, dafs, wenn diese Cemente zur Kunststeinplattenfabrikation verwendet werden, dieselben im Gegensatze zu den meisten gewöhnlichen Cementen keine Flecken erzeugen, sondern gestatten, absolut gleichmä'fsige Färbungen herzustellen.The particular advantage obtained by the present method is that if these cements are used for the manufacture of artificial stone slabs, the same in contrast to them Most common cements do not stain, but allow, absolutely to produce uniform colorations.
Zur Ausübung des Verfahrens bezw. zur Herstellung dunkler, bis schwarzer Cemente verwendet man als Zusatz zu den Rohmaterialien ■Chlorkalk in Mengen von 1 bis 5 pCt, je nach den gewünschten Farbtönen, gegebenenfalls unter Zusatz geringer Mengen Eisenoxyd.To exercise the procedure respectively. used for the production of dark to black cements as an additive to the raw materials ■ Chlorinated lime in quantities of 1 to 5 pCt, depending on the desired color shades, optionally with the addition of small amounts of iron oxide.
Die chemischen Einwirkungen, die sich durch ■den Zusatz von Chlorkalk beim Brennen mit »den Rohmaterialien ergeben, sind folgende:The chemical effects resulting from ■ the addition of chlorinated lime when burning »The raw materials are as follows:
Der Chlorkalk wirkt oxydirend auf die Eisenverbindungen des Rohmaterials und der Kohle, so dafs die höchsten Oxydationsstufen des Eisens entstehen und dadurch die grüne bis schwarze Farbe erzeugt wird.The chlorinated lime has an oxidizing effect on the iron compounds of the raw material and the coal, so that the highest degrees of oxidation of iron arise, and thereby the green to black Color is generated.
Das bei der Verwendung des gewöhnlichen Cementes so oft vorkommende Fleckigwerden auf den Kunststeinplatten gründet sich häufig darauf, dafs sich verschiedene SchwefeleisenundSchwefelcalciumverbindungen bilden. Durch den Zusatz des Chlorkalkes entstehen nun aber flüchtige Chlorschwefelverbindungen, wodurch die fleckenbildenden Schwefelverbindungen beseitigt werden.The staining that so often occurs with the use of ordinary cement On the artificial stone slabs it is often based on the fact that various iron sulphide and calcium sulphide compounds are formed form. However, the addition of the chlorinated lime creates volatile chlorosulphur compounds, which causes the staining sulfur compounds are removed.
