Description
Vorbereitung von Ton für trockene Gestaltung durch hohen Druck mittels Erhitzung. Die Verformung von Ton durch Trockenpressung leidet an dem Übelstand, daß plastischer Ton nur schwer verarbeitet werden kann. Preßlinge aus solchem lassen sich nur unter Schwierigkeiten entformen, werden leicht rissig und verlieren nach dem Pressen den Zusammenhalt.Preparation of clay for dry design using high pressure using Heating. The deformation of clay by dry pressing suffers from the inconvenience, that plastic clay is difficult to process. Let compacts out of such a thing can only be removed from the mold with difficulty, cracks easily and then lose the pressing the cohesion.
Die vorliegende Erfindung umgeht diese Mängel dadurch, daß dem Ton durch Erhitzen die Bildsamkeit genommen wird, indem die üblichen Trockentemperaturen überschritten werden, die eigentliche Brenntemperatur jedoch nicht erreicht wird, worauf sich die Verpressung ohne Mühe ausführen läßt.The present invention overcomes these shortcomings by adding to the sound the ductility is taken away by heating, by the usual drying temperatures are exceeded, but the actual firing temperature is not reached, whereupon the pressing can be carried out without any effort.
Es sind zwar schon Verfahren bekannt geworden, bei welchen der grubenfeuchte Ton durch Erhitzung getrocknet wurde. Jedoch trieb man diese nur so weit, als es für die Vermahlung zu Pulver nötig war. Im Gegensatz zu vorliegendem Verfahren war man bisher der Ansicht, daß der Zustand der Unbildsamkeit des Tones vor der Verpressung vermieden werden müßte. Es wurde deshalb vorgeschlagen, die Erhitzung bis über den für die Vermahlung zu Pulver nötigen Trockenheitsgrad hinaus, aber nicht bis zum völligen Unplastischwerden des Tones zu treiben. Die bekannten Verfahren zum Trocknen des Tones arbeiteten nur mit den gewöhnlichen Trockentemperaturen, also etwa @ioo bis 18o° C.Processes have already become known in which the pit damp Clay was dried by heating. However, one only drove this as far as it did was necessary for grinding to powder. In contrast to the present process, up to now one has taken the view that the state of the incompetence of the clay before pressing should be avoided. It has therefore been suggested that the heating be kept above the Dryness level required for grinding to powder, but not up to to drive the clay to become completely aplastic. The known methods of drying des Tones only worked with the usual drying temperatures, i.e. about @ioo up to 18o ° C.
Demgegenüber geht das neue Verfahren davon aus, dem Ton gerade durch höhere Erhitzung, als mit gebräuchlichen Trockentemperaturen erreicht wird, die Bildsamkeit zu nehmen. Er soll also gewissermaßen sehr schwach .gebrannt werden, sofern man von einem Brennen im Sinne des Wortes sprechen kann, denn hinter der eigentlichen Brenntemperatur soll die Erhitzung in den meisten Fällen sogar weit zurückbleiben.In contrast, the new process assumes that the sound just goes through higher heating than is achieved with conventional drying temperatures that To take plasticity. In a sense, it should be burned very weakly, as long as one can speak of a burning in the sense of the word, because behind the actual firing temperature, the heating should in most cases even be high lag behind.
Bei der praktischen Durchführung der Neuerung wird der zu verarbeitende Ton bzw., wenn dessen Bildsamkeit nicht allzu hoch ist, ein Teil desselben erhitzt. Der anzuwendende Hitzegrad ist dem Charakter des Tones anzupassen. Jedenfalls soll die Bildsamkeit beseitigt werden. Der Hitzegrad liegt zwischen den üblichen Trockentemperaturen und der eigentlichen Brenntemperatur. Von letzterer ist er sehr weit entfernt.In the practical implementation of the innovation, the Clay or, if its malleability is not too high, a part of it is heated. The degree of heat to be used must be adapted to the character of the clay. At least it should the malleability will be eliminated. The degree of heat lies between the usual drying temperatures and the actual firing temperature. He is very far from the latter.
Ein so behandelter Tön hat wie Tonschiefer die Eigenschaft, nach dem Pressen unter hohem Druck beim Brennen in eine feste Ziegelmasse übergeführt zu werden.A clay treated in this way, like slate, has the property that Pressing under high pressure during firing converted into a solid brick mass will.
Um den behandelten Ton zu verwerten, wird er wie Tonschiefer zerkleinert und trockengepreßt. - Unter Trockenpressung ist hier die -Verformung einer nur schwach angefeuchteten Masse zu verstehen. Die Menge des zum Pressen erforderlichen Wassers soll nur so hoch sein, d@aß der zerkleinerte Ton sich ballen läßt, ohne dabei formgerecht zu werden, ein Zustand, wie er für die Masse zür Herstellung von Formlingen mit der Ziegelpresse notwendig ist.In order to utilize the treated clay, it is crushed like slate and dry pressed. - Under dry pressing, the deformation is only weak here to understand moistened mass. The amount of water required to press should only be so high that the crushed clay can be clumped without being properly shaped to become, a state as it is for the mass for the production of Bricks with the brick press is necessary.
