Description

Verfahren zur Verkittung oberflächenaktiver Massen Beim einfachen Mischen von Kittmassen mit oberflächenaktiven Substanzen, wie Aktivkohle, Kieselgel u. dgl. zur Ausformung oder Folienherstellung treten Kittbestandteile in die feinen Poren der Aktivstoffe ein. Dadurch erleidet deren Aktivität eine merkliche Einbuße. Diese Tatsache ist dafür maßgebend, daß man bisher nur durch Pressen mit Fasermaterial ohne Mitverwendung löslicher Bindemittel zum Ziel kam.Method for cementing surface-active compounds In the simple Mixing of putty masses with surface-active substances such as activated carbon, silica gel and the like. For molding or film production, cement components enter the fine Pores of the active ingredients. As a result, their activity suffers a noticeable loss. This fact is decisive for the fact that so far only by pressing with fiber material came to the goal without the use of soluble binders.

Diese Belegung der feinporigen, aktiven FLächen durch Kittbestandteile soll durch das nachstehende Verwahren vermieden werden. Zu diesem Zwecke werden die b.etreffenden Aktivstoffe vor dem Zusammenbringen mit einer Ilittmasse mit einem leicht löslichen oder flüchtigen Adsrorbendum bZeladen. Dieses Adsorbendum darf sich jedoch nicht mit dem Binde- bzw. Lösungs- oder Dispersionsmittel der Kittmaslse vermischen, sondern muß sich gegen diese Bestandteile des Kittes abstoßend verhalten. Wird beispielsweise Ilieseigel mit einem Klebstoff auf Harz- oder Cellulosebasis vermischt, so kann es zuvor mit Wasser oder Wasserdampf abgesättigt werden. Um ein weiteres Beispiel zu nennen, kann Aktivkohle, die mittels eines anorganischen Kittes in wäßriger Dispersion verformt werden soll, zuvor mit Kohlenwasserstoffen gesättigt werden. Es ist auch denkbar, Dämpfe oder Lösungen von festen Stoffen zur Absättigung zu verwenden. Nach Verfestigung oder Abbindung der Kittmasse wird das Adsorhendum in geeigneter Weise, z. B. durch Hitze oder durch Herausspülen mit Lösungsmitteln, wieder aus der aktiven Masse entfernt. This occupation of the fine-pored, active surfaces by putty components should be avoided by keeping them below. Be for this purpose the active substances concerned before being brought into contact with an ilitt mass with a Easily soluble or volatile Adsrorbendum bZeladen. This adsorbent may However, it does not interfere with the binding agent, solvent or dispersion agent of the putty mix, but must be repulsive to these components of the cement. For example, Ilieseigel is made with a resin or cellulose-based adhesive mixed, it can be saturated with water or steam beforehand. To a Another example can be activated carbon, which is made using an inorganic putty to be deformed in aqueous dispersion, previously saturated with hydrocarbons will. It is also conceivable to use vapors or solutions of solid substances for saturation to use. After the cement mass has solidified or set, the adsorhendum becomes in a suitable manner, e.g. B. by heat or by rinsing with solvents, removed again from the active mass.

Dieses Verfahren gestattet die Herstellung oberflächenaktiver Formkörper, Reagensfo-lien u. dgl. mit hoher- Adsorptionswirkung .-und weitgehender Reaktionsf,ähigkeit. This process allows the production of surface-active moldings, Reagent foils and the like with a high adsorption effect and extensive reactivity.
