Description
KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Im Hauptpatent ist ein Entwässerungsverfahren für organische und anorganische Stoffe beschrieben, bei dem der zu entwässernden Substanz vor oder während der möglichst feinen Zerkleinerung ein Elektrolyt zugefügt wird, worauf dann die Masse der Elektroosmose unterworfen wird.The main patent includes a drainage process for organic and inorganic substances described in which the substance to be dehydrated before or during the possible an electrolyte is added to fine comminution, whereupon the mass of electroosmosis is subjected.
Es hat sich nun gezeigt, daß die günstige Wirkung des Elektrolytzusatzes, wie sie im Hauptpatent beschrieben wurde, bei vielen Stoffen nicht oder nur unvollkommen eintritt, daß sie aber bedeutend erhöht werden kann, wenn man der Masse außer einem Elektrolyten auch noch einen kolloiden Körper zusetzt.It has now been shown that the beneficial effect of the addition of electrolytes, as in the Main patent has been described, does not occur or only partially occurs for many substances, but that it can be increased considerably if one of the mass is apart from an electrolyte also adds a colloidal body.
Derartige Körper sind z. B, kolloidale Kieselsäure, Huminsubstanz, organische und anorganische Kolloide usw. Durch den Zusatz solcher Stoffe tritt eine Erhöhung der Wirkung des Elektrolyten ein. Die kolloide Substanz kann der Masse entweder vor oder nach oder gleichzeitig mit dem Elektrolyten zugesetzt werden.Such bodies are z. B, colloidal silica, humic substance, organic and inorganic Colloids, etc. The addition of such substances increases the effect of the electrolyte. The colloidal substance can either be before or after the mass or added at the same time as the electrolyte.
Bei der Behandlung von Steatit hat sich z. B. ein Zusatz von Natriumsilikat als günstig erwiesen. In diesem ist die kolloide Substanz — kolloidale Kieselsäure — und der geeignete Elektrolyt — Natriumhydroxyd — vereinigt. Die erstere wird durch Hydrolyse in Freiheit gesetzt und adsorbiert, während das Alkali den Elektrolyten abgibt.In the treatment of steatite, for. B. an addition of sodium silicate as favorable proven. In this is the colloidal substance - colloidal silica - and the suitable electrolyte - sodium hydroxide - combined. The former is made by hydrolysis set free and adsorbed while the alkali releases the electrolyte.
In anderen Fällen kann jedoch naturgemäß der kolloide Körper für sich zugesetzt werden.In other cases, however, the colloidal body can of course be added by itself.
