Abstract

Zur Herstellung eines Keramikteiles verwendet man zwei Formkörper (14/15) aus porösem Kunststoff, die zwischen zwei Anpressplatten (4a/4b) angeordnet sind. In den Form­ körpern (14/15) befinden sich parallele Kanäle (2), die von einem Kanalnetz (3a/3b) der Anpressplaten (4a/4b) gespeist werden und in Form von Sacklochbohrungen bis knapp an den zur Scherbenbildung dienenden Formraum heranrei­ chen. Two are used to manufacture a ceramic part Shaped body (14/15) made of porous plastic, which between two pressure plates (4a / 4b) are arranged. In the form bodies (14/15) are parallel channels (2) by a duct network (3a / 3b) of the pressure plates (4a / 4b) is fed and in the form of blind holes to just under the shape space used for the formation of the cullet chen.

Nach dem Einfüllen des Schlickers wird derselbe zwecks Beschleunigung der Filtration unter Druck gehalten. Nach dem Ablaufen des Rück- und Hohlraumschlickers, d.h. nach der Bildung des Scherbens (13), wird der verbleibende Hohlraum unter pneumatischen Druck gesetzt, um das Nachlaufen zu verhindern und die weitere Verfestigung zu erreichen. After filling the slip, it is used for the same purpose Accelerated filtration kept under pressure. To the drainage of the back and cavity slip, i.e. to the formation of the body (13), the remaining one Cavity pressurized to the pneumatic To prevent run-on and further solidification to reach.

Das in die Formkörper (14, 15) eingedrungene Filtrati­ onswasser (W) wird im Grenzbereich des Scherbens (13) gehalten, gegebenenfalls durch ein gezieltes Zusammenwir­ ken des pneumatischen Hohlraumdruckes und eines von aussen an die Formkörper (14, 15) angelegten Gegendruc­ kes. Dadurch steht das Filtrationswasser (W) für den Ablöse­ vorgang zur Verfügung. The filtrate which has penetrated into the shaped body (14, 15) onswasser (W) is in the border area of the body (13) held, if necessary through a targeted cooperation pneumatic cavity pressure and one of on the outside against the molded body (14, 15) kes. As a result, the filtration water (W) stands for detachment operation available.

Verwendung zur Herstellung von Geschirr und Sanitär­ keramik, aber auch zur Verarbeitung anderer Substanzen, z.B. Asbestschlicker, zu Formlingen. Use for the manufacture of dishes and sanitary ceramics, but also for processing other substances, e.g. Asbestos slip, to moldings.
