Description
Verfahren zur Herstellung von dünnen Röhrchen oder Plättchen äus keramischer Masse für technische Zwecke Bei der Fabrikation. von elektrischen Kondensatoren mit keramischem Dielektrikum werdest für die Herstellung eines möglichst dünnen Scherblens als Dielektrikum zur Steigerung der Kapazität eines solchen Kondensators hohe Anforderungen an die Verformüngstechnik gestellt. Diese keramischen Isolierteile werden größtenteils in Form von Röhrchen oder dünnen Plättchen hergestellt, wobei die Röhrchen allgemein im sog. keramischen Ziehverfahren geformt werden.Process for the production of thin tubes or plates made of ceramic Dimensions for technical purposes during manufacture. of electrical capacitors with ceramic dielectric will be used for the production of the thinnest possible Scherblens as a dielectric to increase the capacity of such a capacitor high demands are placed on the deformation technology. These ceramic insulating parts are mostly produced in the form of tubes or thin plates, whereby the tubes are generally shaped using the so-called ceramic drawing process.
Es wurde nun gefunden, daß es in Anlehnung an das seit sehr langer Zeit biet kunst= gewerblichen Porzellanen geübte Verfahren zur Nachbildung von Tüll, Spitzen, Pflanzenblättern usw. gelingt, mit viel einfacheren Mitteln ein beliebig dünnwandiges . keramisches Röhrchen herzustellen. Hierzu wird aus glattem Filterpapier z. B. eih Röhr geformt und dieses Filterpapierrohr mit keramischem Masseschlicker getränkt. Im Brand verascht das Filtrierpapier. Die keramische Masse ist aber trocken und besitzt genügend mechanische. Festigkeit, bis mit fortschreitender Temperatur die Sinterung und die Verfestigung des Scherbens eülsetzt.It has now been found that it has been based on that for a very long time Time offers art = commercial porcelains practiced methods for replicating tulle, Tips, plant leaves, etc. can be made as desired with much simpler means thin-walled. to manufacture ceramic tubes. This is done using smooth filter paper z. B. Eih tube shaped and this filter paper tube with ceramic mass slip soaked. The filter paper burns up in the fire. However, the ceramic mass is dry and has enough mechanical. Firmness until with increasing temperature the sintering and solidification of the body takes place.
Auf diese Weise lassen sich beliebig dünne Wandstärken bis herab zu einigen hundertstel Müliinetern formen.In this way, wall thicknesses as thin as desired can be achieved Shape a few hundredths of a millimeter.
Das Verfahren läßt sich auch zur Herstellung von sehr dünnen Plättchen verwenden, die bei dem Preßverfahren in der Matrize beschädigt werden würden.The process can also be used to produce very thin platelets use, which would be damaged in the pressing process in the die.
