Description

Verfahren zum Vorbereiten keramischer lasse für die Pressung in Matrizen. Beim Formen plastischer Masse für keramische Zwecke mittels Matrizen in Pressen wird, um das Anhaften der Masse an den Matrizen zu verhindern, gewöhnlich der Masse ein Ölzusatz gegeben. Um diesen Zusatz zu vermeiden, also die Masse ohne (J', nur mit Wasser anmengen zu können, ist ein neues Vorbereitungsverfahren der Masse riützlicli, welches den Gegenstand der vorliegenden Erfindung bildet. Dieses Verfahren gesteht darin, daß die Masse nicht in teigförmigem Zustand zugeführt wird, sondern in einem Zwischending zwischen teigförtnigem und pulverförmigem Zustand. Die teigförtnigeMasse wird mit so wenig Wasser an-"einen"t, daß sie durch Reiben in einen krümeligen Zustand versetzt werden kann. Diese Mischung wird durch Reiben oder Schlagen zwischen zwei Flächen zu kleineren oder größeren Kugeln geformt, welche bei Gegenständen mit Wandstärken von i-5 mm bis zu i mm Durchmesser haben, bei größeren Gegenständen entsprechend größeren. Diese Kugeln können in der Art von Pulver in die Höhlungen der Matrizen eingeführt werden, würden aber ebenso wie teigförmige Masse an den Matrizen ankleben. Um das zu vermeiden, setzt man diesen teigförinigen Kugeln völlig trockene, pulverförmige Masse zu, mischt -sorgfältig und sorgt dafür, dafi die Presse schnell arbeitet, dann hat die Feuchtigkeit der Kugeln keine Zeit, die Umhüllung von trockenem Pulver zu durchdringen, und ein Ankleben an die Matrize erfolgt nicht. Das Verfahren kann dadurch noch vervollkommnet werden, daß man die zu Kugeln geformte Masse durch Sieben in erschiedene Größen sortiert. Indem man nun entweder gleichförmig große Kugeln odergrößere und kleinere Kugeln durcheinander mischt, sowie indem man das Quantum der zuzusetzenden pulverigen Masse v eranriert, kann man erzielen, daß das spezifische Gewicht der Masse nach Belieben in ziemlich weitem Umfange sich verändert, daß also ein bestimmter Hohlraum der Matrize mehr oder weniger Masse faßt und daß demzufolge die geformten Gegenstände höher oder niedriger ausfallen.Method of preparing ceramic lasses for pressing in matrices. When molding plastic mass for ceramic purposes using dies in presses is used to prevent the mass from sticking to the matrices, usually the mass given an oil additive. To avoid this addition, i.e. the mass without (J ', only To be able to add water to it is a new method of preparing the mass riutzlicli, which forms the subject of the present invention. This procedure confesses in that the mass is not supplied in a dough-like state, but in one Something between doughy and powdery state. The dough-like mass becomes "an" t with so little water that rubbing it into a crumbly state can be moved. This mixture is made by rubbing or beating between two Surfaces formed into smaller or larger spheres, which are used for objects with wall thicknesses from i-5 mm to i mm in diameter, correspondingly for larger objects bigger. These balls can be in the form of powder in the cavities of the dies are introduced, but would stick to the matrices just like dough-like mass. To avoid this, these dough-like balls are completely dry, powdery Add mass, mix carefully and ensure that the press works quickly, then the moisture of the balls does not have time, the coating of dry powder to penetrate, and there is no sticking to the die. The procedure can can be further perfected by sieving the mass formed into spheres assorted in different sizes. By now either balls of the same size or by mixing larger and smaller balls together, as well as by adding the quantum the powdery mass to be added varies, one can achieve that the specific The weight of the mass changes at will to a fairly large extent, that is to say a certain cavity of the die holds more or less mass and that consequently the shaped objects turn out to be higher or lower.
