Description
Verfahren zur Herstellung von für heramische Nassen, Gläser, Glasuren, ferner für die Wasserglas- sowie die Hörtelfabrikation verwendbarem Blinstuff. <B>-</B> Die Verwendung des Bimstuffes zur Her stellung keramischer Massen, Glasuren und <I>Gläser</I> ist bereits früher vorgeschlagen wor den.
Die praktische Ausführung dieses Ge dankens scheiterte jedoch daran, dass die Gläser und Glasuren wegen der Ungleich mässigkeit ihrer Farbe, die keramischen Massen infolge Schlierenbildungen nicht den zu stellenden Anforderungen entsprachen.<B>-</B> Es wurde nun gefunden, dass der Bimstuff sich sehr gut für keramische Zwecke, Gla-- suren und Gläser, ferner für die Wasserglas-, sowie die Mörtelfabrikation verwenden lässt, wenn man ihn vorher von den beigemengten Teilchen des Nebengesteins ("Schiilferchen") befreit hat,
das heisst denjenigen Teilchen der Gesteinmassen, welche den magnetischen Schmelzfluss vor der Eruption überdeckten und beim Ausbruch in fein verteilter Form von den vulkanischen Massen mitgerissen wurden.
Die Entfernung dieser Nebenbestandteile kann in der verschiedenartigsten Weise er- folgen. Man kann hierzu beispielsweise die üblichen mechanischen Aufbereitungsmetho den, wie zum Beispiel Schlämmen und Wa schen, oder auch die sogenannte Zentrifugal- scheidung anwenden. Auch kann unter Um ständen die magnetische. Aufbereitung in Be tracht kommen, mit deren Hilfe die Eisen- erzteilchen entfernt werden. Schliesslich sei in diesem Zusammenhange auch noch die elek trische Aufbereitung erwähnt.
Abgesehen von den vorstehend genannten Aufbereitungs methoden kommt für die Entfernung der störenden Nebenbestandteile auch die che mische Behandlung des Bimstuffes in Betracht, indem beispielsweise mittelst Säuren diese Bestandteile herausgelöst werden.
Je nach den vorliegenden Verhältnissen lassen sich natürlich auch die oben angegebe nen Methoden kombinieren.
Durch die vorliegende Erfindung ist dem Bimstuff ein vollkommen neues Anwendungs gebiet erschlossen worden.
Process for the production of blinstuff which can be used for heramical wetness, glasses, glazes, furthermore for water glass and Hörtelfabrikation. <B> - </B> The use of the pumice stuff to produce ceramic bodies, glazes and <I> glasses </I> has already been suggested earlier.
However, the practical implementation of this idea failed because the glasses and glazes did not meet the requirements due to the unevenness of their color and the ceramic masses due to streaking. <B> - </B> It has now been found that the pumice stuff can be used very well for ceramic purposes, glazes and glasses, furthermore for water glass and mortar production, if it has been freed from the admixed particles of the adjacent rock ("Schiilferchen"),
that is, those particles of rock that covered the magnetic melt flow before the eruption and were carried along in finely divided form by the volcanic masses during the eruption.
These secondary constituents can be removed in the most varied of ways. For example, the usual mechanical processing methods, such as sludge and washing, or so-called centrifugal separation can be used for this purpose. Under certain circumstances, the magnetic. Processing come into consideration, with the help of which the iron ore particles are removed. Finally, electrical processing should also be mentioned in this context.
Apart from the processing methods mentioned above, the chemical treatment of the pumice stuffing can also be used to remove the troublesome secondary components, for example by using acids to dissolve these components.
Depending on the prevailing conditions, the methods given above can of course also be combined.
The present invention has opened up a completely new field of application for pumice stuffing.
