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.
