Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Es sind Verfahren der Herstellung von Kunststeinen bekannt geworden, bei welchen das in Formen gebrachte Gemenge unter hohem Druck und gleichzeitiger Evakuierung der Einwirkung von Hitze ausgesetzt wird. Dieses Verfahren ist umständlich, zeitraubend und erfordert eine verwickelte Einrichtung zur Erzielung des hohen Druckes und zur Herbeiführung des Vakuums.There are methods of manufacturing artificial stones have become known in which the mixed mixture under high pressure and evacuation at the same time exposed to heat. This procedure is cumbersome, time consuming and requires an intricate facility for high pressure and induction of the vacuum.

ίο Durch das neue Verfahren sollen diese Mängel beseitigt werden.ίο The new procedure addresses these shortcomings be eliminated.

Das Wesen der Erfindung besteht darin, daß das ungefärbte oder gefärbte, aus Stoffen wie Asche zusammen mit feingeflocktem, mineralischem Faserstoff bestehende Preßgut in feiner Verteilung mittels leicht verdampfbarer Bindemittel, wie in Lösung gebrachter Öle, zu einem Teig verarbeitet wird und dann in geschlossener, aber nicht abgedichteter Preßform, die dem Fortschreiten des Preßdruckes entsprechend nachspannbar ist, einem mäßigen Druck ausgesetzt wird. Das Preßgut wird dann erhitzt, nachgepreßt, wiedererhitzt und dann schnell abgekühlt.The essence of the invention is that the undyed or colored, made of fabrics like ash together with finely flaked, mineral fiber material existing pressed material in fine distribution by means of easily evaporable binders, such as those brought into solution Oils, made into a dough and then placed in a closed but unsealed Die, which can be re-tensioned according to the progression of the pressing pressure, one moderate pressure is applied. The material to be pressed is then heated, re-pressed and reheated and then cooled quickly.

Das Gemisch wird in Formen gefüllt, und diese Formen werden durch einen mittels Klammern o. dgl. festgehaltenen Deckel verschlossen, aber nicht abgedichtet. Hierauf wird die gefüllte Form unter einer gewöhnliehen Presse gepreßt und dann in den Trockenofen gebracht. Die sich bildenden Gase suchen zu entweichen, was jedoch durch den Deckelverschluß erschwert wird. Infolgedessen entsteht ein starker, innerer Druck. Es erfolgt dann ein Nachpressen, worauf die Form wieder in den Ofen kommt. Hierbei zeigt es sich, daß das vergaste Lösungsmittel unter Feuererscheinung verbrennt. Schließlich wird die Form aus dem Ofen genommen und nach Bedarf nochmals gepreßt. Oder es wird der Formling sogleich herausgenommen. Nach rascher Abkühlung ist er sofort gebrauchsfertig. The mixture is filled into molds, and these molds are made by means of a Clamps or the like. Fixed lid closed, but not sealed. On that the filled form is pressed under an ordinary press and then placed in the drying oven brought. The gases that are formed try to escape, but this is done through the lid lock is made more difficult. As a result, there is strong, internal pressure. There is then a re-pressing, whereupon the shape again comes in the oven. It was found that the gasified solvent appeared under fire burns. Finally, the mold is taken out of the oven and used as needed pressed again. Or the molding is taken out immediately. To it is ready for use immediately after cooling down.
