Description

Verfahren zur Herstellung zusammengesetzter Porzellan- und Steinzeugkörper Die Herstellung großer Formstücke aus Porzellan, Steinzeug oder ähnlichen keramischen Stoffen, wie sie insbesondere in der Elektrotechnik, z. B. als Hochspannungsisolator, benötigt werden, ist bisher begrenzt durch die Schwierigkeiten, die in Sehwindung, Rißbildung und inneren Spannungen bestehen und dann auftreten, «renn ein gewisses Maß der Formstücke überschritten wird. Man hat sich in den meisten Fällen, insbesondere bei der Herstellung großer Isolatoren, durch das Verkitten der Formstücke geholfen, das jedoch verschiedene Nachteile besitzt. Da als Kittsubstanz meist nur Zemente in Frage kommen, dürfen die Fugen solcher zusammengesetzter Stücke mechanisch nicht hoch beansprucht werden. Da ferner alle Zemente wasseraufnahmefähig sind, mußten die Verbindungsstellen nach innen gelegt und sorgfältig vor Feuchtigkeit geschützt werden, da sonst die Gefahr der Isolationsverminderung und des Zerfrierens besteht.Process for the production of composite porcelain and stoneware bodies The production of large shaped pieces from porcelain, stoneware or similar ceramic Substances such as those used in electrical engineering in particular. B. as a high voltage insulator, required is so far limited by the difficulties involved in visual curl, Cracking and internal tension exist and then occur, "run a certain Dimension of the fittings is exceeded. One has for the most part, in particular in the production of large insulators, helped by cementing the fittings, however, this has several disadvantages. Usually only cement is used as the cement substance come into question, the joints of such assembled pieces must not be mechanical are highly stressed. Furthermore, since all cements are water-absorbent, they had to the connection points are placed inwards and carefully protected from moisture otherwise there is a risk of reduced insulation and freezing.

lach dem vorliegenden Verfahren gelingt es,- Formkörper aus beliebigen keramischen Massen in jeder gewünschten Größe und Gestalt von außerordentlicher Festigkeit herzustellen, wodurch sich eine Reihe neuer Konstruktionsmöglichkeiten eröffnet.According to the present method, it is possible to - moldings from any ceramic masses in any desired size and shape of extraordinary Establish strength, which opens up a range of new design options opened.

Das Verfahren besteht darin, daß die Formstücke aus einzelnen, durch Fugen getrennten Stücken zusammengesetzt werden, wobei die Fugen aus Hartgummi hergestellt werden.The method is that the fittings from individual, by Joints separate pieces are put together, the joints made of hard rubber will.

Zur Durchführung des Verfahrens werden die miteinander zu verbindenden Stücke zweckmäßig an den Paßflächen von Glasur entblößt bzw. an diesen Stellen ohne Glasur hergestellt, vorteilhaft mit einer vulkanisierbaren Gummilösung bestrichen und sodann unter Zwischenlegung einer noch plastischen Hartgummimasse unter Druck zusammengefugt und durch Erwärmung oder chemische Behandlung das Material der Fuge zum Abbinden bzw. Erhärten gebracht.In order to carry out the process, the Pieces expediently bare of glaze on the mating surfaces or without glaze in these places Glaze produced, advantageously coated with a vulcanizable rubber solution and then with the interposition of a still plastic hard rubber compound under pressure joined together and the material of the joint by heating or chemical treatment brought to setting or hardening.

Es ist bereits vorgeschlagen worden, Porzellangegenstände zwecks genauer Bearbeitung, Anbringung von Gewinden usw. an den zu bearbeitenden Stellen mit einem Hartgummiüberzuge zu versehen, da letzterer sich leichter und präziser bearbeiten läßt.It has already been suggested to use porcelain objects in order to be more precise Machining, application of threads, etc. at the points to be machined with a To provide hard rubber covers, as the latter can be machined more easily and precisely leaves.

Das vorliegende Verfahren bezweckt dagegen lediglich die Verbindung von Porzellan-bzw. Steinzeugteilen miteinander, wodurch eine andere mechanische Verbindungsart der Teile vollkommen überflüssig wird.The present proceedings, on the other hand, are only intended to provide a connection of porcelain or. Stoneware pieces with each other, creating a different mechanical Type of connection of the parts is completely superfluous.

So hergestellte Körper aus keramischen Massen zeigen auch bei den größten Gesamtabtnessungen die guten Eigenschaften des an- gewandten Materials, zugleich hohe Festigkeit, völlige Wasserundurchlässigkeit und gute Isolation.Bodies made of ceramic masses produced in this way show the good properties of the versatile material, at the same time high strength, complete impermeability to water and good insulation.
