Description

Verfahren zur Herstellung von Kunststeinen zum Aufsaugen von Feuchtigkeit Kunststeine zum Löschen von Schreibtinte, Tusche und ähnlichem wurden bekannterweise schon lange aus verschiedenartig zusammengesetzten Massen hergestellt. In der Hauptsache verwendete man hierfür neben Ton und Zement und Silica besonders Gips. Diesen Grundstoffen setzte man Füll- und Farbstoffe zu. Bei den mit Silica oder Gips zusammengesetzten Steinen trat trotz der vorzüglichen Saugwirkung der Übelstand zutage, daß diese Steine bei ihrer Verwendung stets sehr stark Staub absonderten oder beim Hinlegen oder Berühren Spuren hinterließen. Steine mit Ton oder Zement zusammengesetzt stauben zwar nicht so stark, haben aber auch eine geringere Saugwirkung.Process for the production of artificial stones for absorbing moisture Artificial stones for erasing writing ink, Indian ink and the like have become known long made from masses of different compositions. In the main In addition to clay, cement and silica, plaster of paris was used for this purpose. These raw materials fillers and dyes were added. In the case of those composed with silica or plaster of paris In spite of the excellent suction effect, stones came to light that this Stones always gave off a lot of dust when they were used or when they were lying down or touching it. Dust stones composed with clay or cement not as strong, but they also have a lower suction effect.

Das neue Verfahren zur Herstellung dagegen ergibt Steine, welche nicht stauben und nicht abfärben, deren Saugwirkung jedoch ganz hervorragend ist.The new method of manufacture, on the other hand, results in stones that are not dust and not rub off, but the suction effect is excellent.

Das Verfahren ist folgendes: Kunststeimnassen zum Aufsaugen von Flüssigkeiten, wie Tinte, Tusche, Wasser o. dgl., werden, wie üblich, aus Zement, Silica, Gips mit Füll- oder Farbstoffen in eingefettete Formen gegossen und nach dem Abbinden aus diesen entfernt. Nachdem die Steine aus der Form genommen sind, werden sie in einem Bad von fettlösenden Stoffen, wie z. B. Benzin, Benzol, Solvenfinaphtha und ähnlichen, mit einem Zusatz von Sprit von dem anhaftenden Fettfilm befreit. Die vom Fettfilm befreite Außenfläche des Steines wird fest und hart und läßt die Innenfeuchtigkeit des Steines nach außen verdunsten, wodurch die Trockendauer erheblich herabgesetzt wird.The procedure is as follows: artificial stone for absorbing liquids, such as ink, Indian ink, water or the like, are, as usual, made of cement, silica, plaster of paris Poured into greased molds with fillers or dyes and after they have set removed from these. After the stones are removed from the mold, they are put into a bath of degreasing substances, such as B. Gasoline, Benzene, Solvenfinaphtha and similar ones, freed from the adhering grease film with the addition of fuel. the The outer surface of the stone freed from the grease film becomes firm and hard and leaves the inner moisture evaporate to the outside of the stone, which significantly reduces the drying time will.

Die so hergestellten und behandelten Steine werden dann nach dem Abbinden weiter erfindungsgemäß mit einer verdünnten Lösung von Glycerin getränkt' und getrocknet und sind gebrauchsfertig. Das Glycerin verdunstet sehr schwer und bindet den Staub; stört aber nicht die Saugwirkung.The stones produced and treated in this way are then set after they have set further soaked according to the invention with a dilute solution of glycerol and dried and are ready to use. The glycerine is very difficult to evaporate and binds the dust; but does not disturb the suction.
