Zusatz zum Patent 291672.Addendum to patent 291672.
Im Patent 291672 ist ein Verfahren zur Trennung von Komponenten aus Gemischen, die Suspensions- oder Emulsionskolloide, echte Kolloide, Ionen oder gelöste Körper enthalten, beschrieben, welches darauf hinausläuft, daß man unter Verwendung von Diaphragmen geeigneter Ladefähigkeit die Gemische der Wirkung des elektrischen Stromes aussetzt. Die Wirkung des dort beschriebenen Verfahrens ist, daß bestimmte Komponenten der Ge-Patent 291672 describes a method for separating components from mixtures, which contain suspension or emulsion colloids, true colloids, ions or solutes, described, which boils down to the fact that one more suitable using diaphragms Charging capacity that exposes mixtures to the effect of the electric current. The effect of the procedure described there is that certain components of the
"\ mische die Diaphragmen durchwandern, an- -. dere zurückgehalten werden, wodurch die gewünschte Trennung, die außerdem noch zu einer weiteren Fraktionierung ausgedehnt werden kann, eintritt."\ mix the diaphragms to wander through, others to be held back, creating the desired Separation, which can also be extended to further fractionation, occurs.
Es hat sich nun bei der Bearbeitung gewisser Gemische gezeigt, daß die Diaphragmenwirkung für gewisse Stoffe, die zum Diaphragma eine verschiedene Ladung aufweisen, im Verlauf des Verfahrens mehr und mehr in ihrer Wirksamkeit nachläßt, so daß schließlich eine Wanderung der betreffenden Stoffe völlig aufhört. Es wurde gefunden, daß man dagegen in jedem Falle ein dauerndes Arbeiten der Apparatur dadurch erzielen kann, daß man die Flüssigkeit intensiv rührt. In diesem Falle erleidet die Wirksamkeit der Diaphragmen von Anfang .bis zu Ende des Prozesses • keinerlei Veränderung, und die Komponenten wandern während der ganzen Dauer des Vorganges gleichmäßig.It has now been shown in the processing of certain mixtures that the diaphragm effect for certain substances which have a different charge to the diaphragm, more and more in the course of the process their effectiveness diminishes, so that finally a migration of the substances in question completely stops. It has been found that, on the other hand, one has to work continuously in every case the apparatus can be achieved by stirring the liquid intensively. In this Trap suffers from the effectiveness of the diaphragms from the beginning to the end of the process • no change whatsoever, and the components migrate throughout the process evenly.
Während in der Regel das Rühren von Suspensionen den Zweck hat, den suspendierten Körper gleichmäßig in der Flüssigkeit zu verteilen, dient das Rühren bei vorliegendem Verfahren dazu, diejenigen kolloidalen Teilchen, welche nur eine geringe Ladung besitzen, in1 die Nähe des stark geladenen Diaphragmas zu bringen und so durch das Potential des Diaphragmas auch ein Wandern dieser an sich schwach geladenen Teilchen zu bewirken. Es hat fernerhin den Zweck, das Auftreten alkalischer bzw. saurer Schichten in der Nähe der Diaphragmen, welche die Wanderung gewisser Kolloide beeinträchtigen würden, zu verhindem, sowie das Ansetzen von undurchlässigen oder störenden Schichten an den Diaphragmen zu verhüten.While in general, the stirring of suspensions having the purpose to distribute the suspended body uniformly in the liquid, the stirring in the present process the proximity of the highly charged diaphragm serves to those colloidal particles which have only a low charge, in 1 to and thus also cause these weakly charged particles to migrate through the potential of the diaphragm. It also has the purpose of preventing the occurrence of alkaline or acidic layers in the vicinity of the diaphragms, which would impair the migration of certain colloids, and of preventing the formation of impermeable or interfering layers on the diaphragms.
