Description
Verfahren, um einen Stoff in Körper von vorausbestimmbarer Form und Grösse zu bringen. Verfahren, um Stoffe, zum Beispiel Na triumsulfid etc., in Körper von varauis- bestimmbarer Form und Grösse zu bringen, bei dienen man den !Stoff in geschmolzenem Zustande auf temperierte Flächen auftropfen lässt, sind bekannt.
Dabei werden, um ein Anhaften der Substanzen auf den Flächen zu vermeiden, diese zum Beispiel mit einem hauchfeinen Überzug von Vaseline versehen.
Auf diese Weise .gewinnt man runde Kör per in. Oblaten- !bis fast .Halbkugelform, je nach der Wahl der Tropfhöhe und der Tem- peralurdes Sclhmelzflus:ses.
Es wurde nun die Beo!baehtung gemacht, dass die Form der Körper nicht nur von der Tropfhöhe und der Temperatur des Schmelz- flusses .abhängig ist, sondern in weitgehen dem Masse von der Art der Vorbehandlung der Tropffläche. Die Ofberflächensp.annung der Tropfen ;genügt in vielen Fällen nicht, um Blättchen von der gewünschten Dicke zu liefern.
Dieses wind aber erreicht, wenn man die Oberflächen mit einem -dünnen Überzug eines hochviskosen, Stoffes versieht, wodurch der Ausbreitung des Tropfens in weitgehen- .dem Masse entgegengewirkt wind. Man .er hält .so Körper von erheblicher Dicke.
Zur Vorbehandlung der Oberflächen kann man hochviskose Öle .oder Fette verwenden, überhaupt alle Stoffe von hoher Viskosität, die wasserabstossend wirken.
Das. Aufbringen der viskosen :Stoffe auf die Oberfläche in genügend dünner Schicht bereitet in vielen Fällen ,Schwierigkeiten, die sich aber leicht vermeiden lassen, wenn man die Behandlung der Flächen bei höherer Tem peratur, bei der -die Viskosität vermindert ist, vornimmt, oder aber die viskosen .Stoffe in Form von Lösungen anwendet und läas Lö sungsmittel verdampft.
Auf diese Weise er hält man bequem hauchdünne Überzüge:, die zur Verunreinigung von Chemikalien keine Veranlassung .geben. Verwendet man hoch viskose Mineralöle, wie Zylinderäl oder Hoch- druckkampresso-renäl zur Vorbehandlung der Flächen, so löst man diese am besten in Ben zin. Je nach dem gewünschten Grade der Vorbehandlung der Oberflächen wendet man 20-, 10-, 5-, ja 1%ige Lösungen an. Nach dem Verdampfen des Benzins verbleibt auf .den Oberflächen ein hauchdünner Überzug des hochviskosen Öls.
Process to bring a substance into a body of a predictable shape and size. Processes to bring substances, for example sodium sulfide, etc., into bodies of a form and size that can be determined by varauis, in which the substance is allowed to drip in a molten state onto temperature-controlled surfaces are known.
In order to prevent the substances from sticking to the surfaces, they are provided, for example, with a very fine coating of Vaseline.
In this way round bodies are obtained in wafer-like to almost hemispherical shape, depending on the choice of drop height and the temperature of the mud flux.
The observation has now been made that the shape of the bodies is not only dependent on the drop height and the temperature of the melt flow, but also largely on the type of pretreatment of the drop surface. The surface tension of the droplets is in many cases insufficient to produce leaflets of the desired thickness.
This wind is achieved, however, if the surfaces are provided with a thin coating of a highly viscous substance, which largely counteracts the spread of the droplet. You hold a body of considerable thickness.
Highly viscous oils or fats can be used to pretreat the surfaces, in general all substances of high viscosity that have a water-repellent effect.
The. Application of the viscous: substances on the surface in a sufficiently thin layer causes difficulties in many cases, but these can easily be avoided if the treatment of the surfaces at a higher temperature, at which the viscosity is reduced, or else the Applies viscous substances in the form of solutions and allows solvents to evaporate.
In this way, you can easily hold wafer-thin coatings, which do not give rise to any chemical contamination. If you use highly viscous mineral oils such as cylinder oil or high-pressure campresso oil to pretreat the surfaces, it is best to dissolve them in benzine. Depending on the desired degree of surface pretreatment, 20, 10, 5, even 1% solutions are used. After the petrol has evaporated, a very thin coating of the highly viscous oil remains on the surfaces.
