Description

Verfahren zur Herstellung von Körpern aus bildsamer 1Vlasse. Zusatz zum Patent 418 708. Die Erfindung betrifft eine weitere Ausbildung und Verbesserung älterer Verfahren des Erfinders zur Herstellung dauerhafter Gegenstände aus keramischen und hydraulisch erhärtenden Massen, besonders nach Patent 418708.Process for the production of bodies from plastic 1Vlasse. additive See patent 418,708. The invention relates to a further form and improvement prior method of the inventor for making permanent articles from ceramic and hydraulically hardening compounds, especially according to patent 418708.

Man kann nämlich in vielen Fällen, anstatt nach der ersten oder der endgültigen Formgebung einen allseitig wirkenden starken Druck anzuwenden, auch die Masse vor der Formgebung, also solange sie ein noch zu verarbeitendes rohes Werkstück in Form eines Blocks, einer Platte o. dgl. bildet, dem allseitigen hohen Druck aussetzen. So kann die Rohmasse vor dem Formen in feuchtem, halbfeuchtem oder auch trockenem Zustande dem starken Druck unterzogen und dann aus der gepreßten und gegebenenfalls abgebundenen Masse das eigentliche geformte Gebilde oder mehrere Gebilde durch Drehen oder in sonst bekannter Weise herausgearbeitet werden.In many cases, instead of following the first or the Applying strong pressure from all sides to final shaping, too the mass before shaping, i.e. as long as it is a raw material that has yet to be processed Workpiece in the form of a block, a plate or the like. Forms the all-round high Apply pressure. So the raw mass can be in moist, semi-moist or also subjected to the strong pressure in the dry state and then from the pressed and optionally set mass, the actual shaped structure or more Forms can be worked out by turning or in any other known manner.

Wird die Pressung beispielsweise in einem flüssigen Druckmedium ausgeführt, so 'besteht die Gefahr, daß dieses zum Teil in die zu verdichtende Masse eindringt. Lm dieses zu verhindern, kann gemäß der Erfindung die zu pressende Masse mit einer dünnen Schicht von Kautschuk oder anderen geeigneten Stoffen umgeben werden, die das Eindringen verhindern, aber die Übertragung des Druckes auf den zu pressenden Körper in vollem Umfange gestatten. Die Anwendung einer solchen Zwischenschicht ist von großer praktischer Bedeutung; sie kommt auch in solchen Fällen in Frage, wo die Formgebung des Gebrauchsgegenstandes aus noch nicht verdichteter Rohmasse geschieht.If the pressing is carried out, for example, in a liquid pressure medium, so 'there is a risk that this partially penetrates into the mass to be compacted. To prevent this, according to the invention, the mass to be pressed with a be surrounded by a thin layer of rubber or other suitable material prevent the penetration, but the transfer of the pressure to the one to be pressed Allow the body to its full extent. The application of such an intermediate layer is of great practical importance; it can also be used in such cases where the shape of the commodity is made from raw material that has not yet been compacted happens.

Ebenso läßt sich das Eindringen des Druckmediums dadurch vermeiden, daß den zu pressenden Körpern Stoffe zugesetzt werden, die das Druckmedium abstoßen. Ist ersteres z. B. Wasser, so wird bei keramischen 1Zassen durch Zusatz von Öl, Fett o. dgl., z. B. auch durch Ceresit, die Wasseraufnahme beim Pressen verhindert.The penetration of the pressure medium can also be avoided by that the bodies to be pressed substances are added which repel the pressure medium. Is the former z. B. water, then with ceramic 1Zassen by adding oil, Fat or the like, e.g. B. also through Ceresit, which prevents water absorption during pressing.
