Verfahren zur Herstellung von durchscheinendem Kampfer in Formstücken.
Dio vorliegende Erfindung betrifft ein Verfahren zur Herstellung von durchscheinenden Blöcken, Platten, Stangen oder sonstigen Formstücken aus körnigem, pulverförmigem oder kristallisiertem Kampfer. Das Verfahren besteht darin, dass man des Kampfer im luftverdünnten Raum in die gewünschte Form presst.
Es ist zwar bekannt, Kampfer durch langsame Sublimation in ein"durchscheinenden, festen Körper von bestimmter Form überzuführen. Diese Behandlung ist aber mit erheblichen Verlusten an Material verbunden und erfordert beträchtliche Zeit. Auch ist es üblich.
Kampfer lediglich durch Pressen in bestimmte Körperform zu bringen, jedoch haben solche
EMI1.1
undurchsichtigen Stellen durchsetzt.
Erfinder hat nun erkannt, dass diese Erscheinungen durch die beim Pressen eingeschlossene Luft hervorgerufen werden, aber dadurch, dass das Pressen im luftverdünnten Raum vorgenommen wird, nicht entstehen können.
Es können zur Ausführung des Verfahrens Pressen fast jeder Bauart benützt werden, bei denen die eigentlichen Pressorgan (Presstopf und Pressstempel) mit einer Luftpumpe in Verbindung stehen, die während des Pressens die Luft aus dem Pressraum absaugt.
Auch kann man die Pressen, namentlich dann, wenn die Zu-und Abführung des Pressgutes selbsttätig geschieht, in einem Raum aufstellen, in dem dauernd ein Luftunterdruck erhalten wird.
Das Verfahren kann bei jeder Temperatur durchgeführt werden, die die Schmelz- wärme des Kampfer nicht überschreitet, und der Druck entspricht dem gewöhnlich beim Pressen von Kampfer nach der, alten Methode angewendeten Druck von ungefähr 50 kg und darüber auf den cm2, d. h. er muss genügend sein, das Aneinanderhaften der Kampferpartikel zu ermöglichen.

Process for the manufacture of translucent camphor in molded pieces.
The present invention relates to a method for the production of translucent blocks, plates, rods or other shaped pieces from granular, powdery or crystallized camphor. The process consists of pressing the camphor into the desired shape in an air-diluted room.
It is known to convert camphor into a "translucent, solid body of a certain shape by slow sublimation. However, this treatment is associated with considerable losses of material and requires considerable time. It is also common.
To bring camphor into a certain body shape only by pressing, but have such
EMI1.1
opaque places interspersed.
The inventor has now recognized that these phenomena are caused by the air enclosed during pressing, but cannot arise because the pressing is carried out in the air-diluted space.
Almost any type of press can be used to carry out the process, in which the actual press element (press pot and press ram) are connected to an air pump that sucks the air out of the press chamber during pressing.
The presses can also be set up in a room in which a negative air pressure is maintained at all times, especially when the material to be pressed is fed in and discharged automatically.
The process can be carried out at any temperature not exceeding the heat of fusion of the camphor, and the pressure corresponds to the pressure usually used in pressing camphor according to the old method of about 50 kg and above to the cm2, i.e. H. it must be sufficient to allow the camphor particles to adhere to one another.
