Description
Verfahren zur Herstellung von Formkörpern, insbesondere für Bauzwecke Bausteine und andere Formkörper werden seit langer Zeit aus Ton oder tonhaltigen Mineralien hergestellt, indem diese geformt, getrocknet und gebrannt werden. Dies ist jedoch mit, gewissen Nachteilen verbunden, vor allem mit einem hohen Brennstoffaufwand. Ein anderes bekanntes Verfahren ist, aus Quarzsand und Quarzmehl mit gebranntem Kalk als Bindemittel solcheFormkörper herzustellen und sie durch längere Einwirkung von Dampf von etwa 8 atü zu härten. Dieses Verfahren erfordert wesentlich weniger Brennstoff, ist aber trotz seiner Vorteile in seiner Anwendung örtlich beschränkt, da es aus wirtschaftlichen Gründen an Gegenden gebunden ist, in denen geeigneter Sand in ausreichender Menge und in nächster Nähe zur Verfügung steht. Ein weiterer Nachteil dieses Verfahrens gegenüber den aus gebranntem Ton hergestellten Formkörpern besteht darin, daß wegen der schlechten Formbarkeit der Kalk-Sand-Mischungen weder Hohl- noch Leichtsteine angefertigt werden können.Process for the production of moldings, in particular for building purposes For a long time, building blocks and other shaped bodies have been made of clay or clay Minerals made by shaping, drying and firing them. this is, however, associated with certain disadvantages, especially with a high fuel consumption. Another well-known process is, from quartz sand and quartz powder with calcined Lime as a binding agent to produce such molded bodies and protect them by prolonged exposure to harden by steam of about 8 atmospheres. This procedure requires much less Fuel, but despite its advantages it is locally limited in its application, since for economic reasons it is tied to areas where more suitable Sand is available in sufficient quantity and in close proximity. Another Disadvantage of this process compared to the moldings made from baked clay is that because of the poor formability of the lime-sand mixtures neither Hollow or lightweight stones can be made.
Die vorliegende Erfindung hat ein Verfahren zum Gegenstand, nach dem an Stelle von Quarzsand u. dgl. Ton oder tonhaltige Mineralien mit geringen Mengen von Alkalien, Erdalkalien oder deren Verbindungen, vorzugsweise von gebranntem Kalk, unter Zusatz von Wasser innig gemischt werden. Diese Mischungen werden in an sich bekannter Weise durch Pressen, Walzen; Stampfen, Gießen o. dgl. geformt, und die hergestellten Formkörper werden dann in ebenfalls an sich bekannter `''eise durch Behandeln mit Dampf gehärtet. Dabei werden die bisher verwendeten nicht oder schlecht verformbaren Stoffe ganz oder teilweise durch bildsamere, im übrigen gleichwertige Stoffe ersetzt, so daß einerseits die Mängel der vorgenannten Verfahren in Wegfall kommen, andererseits ihre Vorteile ausgenutzt werden. Der Mischung können Füll- oder Farbstoffe oder beide zugegeben werden. .The present invention is directed to a method according to which instead of quartz sand and similar clay or clay-containing minerals in small quantities of alkalis, alkaline earths or their compounds, preferably quick lime, be intimately mixed with the addition of water. These mixtures are in themselves known way by pressing, rolling; Stamping, pouring or the like. Shaped, and the produced moldings are then also better known per se `` hardened by steam treatment. The previously used non-deformable or poorly deformable materials in whole or in part by more malleable, im other equivalent substances replaced, so that on the one hand the shortcomings of the aforementioned Procedures are no longer applicable, and on the other hand their advantages are exploited. The mix fillers or dyes or both can be added. .
Das Verfahren beruht darauf, daß an Steile der nach den bekannten Verfahren angewendeten freien Kieselsäure des Quarzes die Salze derselben, z. B. Aluminiumsalze der Kieselsäure, die; den Hauptbestandteil der Tone bilden, mit den Alkalien oder Erdalkalien, insbesondere gebranntem Kalk; in Reaktion gebracht werden, wobei ebenfalls Verbindungen von hoher Festigkeit entstehen.The method is based on the fact that at steep of the known Process applied free silica of the quartz the salts thereof, e.g. B. Aluminum salts of silica, the; form the main component of the clays, with the Alkalis or alkaline earths, especially quick lime; be brought into reaction, connections of high strength also arise.
Ein wesentlicher Vorteil des Verfahrens gemäß der Erfindung besteht darin, daß die danach hergestellten Formkörper trotz der mangelnden Wasserbeständigkeit des Tons selbst wasserfest werden und zudem raumbeständig sind, so daß das sonst beim Trocknen von Ton oder tonhaltigen Stoffen auftretende starke Schwinden nicht mehr eintritt. Außerdem tritt beim erfindungsgemäßen Verfahren gegenüber der Verwendung von gebranntem Ton eine wesentliche Ersparnis an Brennstoff ein.There is a major advantage of the method according to the invention in that the moldings produced thereafter in spite of the lack of water resistance of the clay itself become waterproof and are also spatially stable, so that otherwise The strong shrinkage that occurs when drying clay or clay-containing materials is not more occurs. In addition, the method according to the invention is not used of fired clay a substantial fuel saving.
Voraussetzung für ein gleichmäßig hochwertiges Erzeugnis ist in Anbetracht der nur in geringem Ausmaß erforderlichen Alkali- oder Erdalkalimenge eine durchaus homogene Vermischung der Ausgangsstoffe. Infolge der für die Herstellung von Formkörpern besonders günstigen Eigenschaft der Tone, insbesondere des Lehms, ergibt sich für das Verfahren gemäß der Erfindung im Gegensatz zu den bekannten Verfahren ein sehr vielseitiges Anwendungsgebiet insofern, als es sich sowohl zur Herstellung sehr fester hohlraumfrei-er als auch sehr leichter, poröser Körper eignet und diese, z. B. bei Herstellung von Bausteinen, als Voll- und Lochsteine hergestellt werden können. Weiter eignet sich das Verfahren auch besonders gut für die Herstellung von Formkörpern, die für spezielle Zwecke bituminöse Stoffe enthalten müssen. Diese Stoffe werden der Mischung in feinst verteilter Form, z. B. als wäßrige Dispersion, zugesetzt oder während des Mischverfahrens in den Mischungen dispergiert. -Die Menge des Zusatzwassers richtet sich nach dem für die Herstellung .der Formkörper angewendeten Arbeitsverfahren, nach dem Mischungsverhältnis der Ausgangsstoffe sowie nach den von den fertigen Körpern verlangten Eigenschaften und auch nach der Art und Menge der gegebenenfalls der Mischung beigemischtenA prerequisite for a consistently high quality product is in consideration the only small amount of alkali or alkaline earth required homogeneous mixing of the starting materials. As a result of the production of moldings particularly favorable property of the clays, especially the loam, results for the method according to the invention in contrast to the known methods a very Versatile application in that it is very suitable for both manufacture solid void-free as well as very light, porous body is suitable and this, z. B. in the production of blocks, as solid and perforated blocks are made can. The method is also particularly suitable for production of moldings that must contain bituminous substances for special purposes. These Substances are added to the mixture in finely divided form, e.g. B. as an aqueous dispersion, added or dispersed in the mixtures during the mixing process. -The amount of the make-up water depends on that used for the production of the moldings Working method, according to the mixing ratio of the starting materials and according to the properties required of the finished bodies and also according to the type and quantity which may be added to the mixture
