Description

Verfahren zur Herstellung poröser Kunststein-1VIassen Es ist eine größere Anzahl von Verfahren zur Herstellung poröser Kunststein-Massen bekannt, die jedoch entweder wenig wirtschaftlich oder aber in Fällen, in denen weder ein Brennen noch ein Auslaugen usw. stattfinden kann, überhaupt nicht erfolgreich ausführbar sind: Diese Schwierigkeiten überwindet das der Erfindung zugrunde liegende Verfahren. Das Wesentliche des Verfahrens besteht darin, daß in dem zur Erstarrung erforderlichen flüssigen Mittel, in der Regel Wasser, ein Gel mehr oder minder fein zerteilt in einer derartigen Menge schwimmt, daß die freie Flüssigkeit nur die Zwischenräume zwischen den Gelstückchen ausfüllt. Voraussetzung ist natürlich, daß das Gel selbst sich nicht in der Flüssigkeit löst. Wird nunmehr ein die Flüssigkeit zur Abbindung aufnehmendes Material hinzugefügt, so erstarrt es in den Zwischenräumen der Gelteilchen zu einem schwammartigen porösen Gebilde. Dieses Gebilde kann entweder im Entstehungszustand selbst benutzt werden (z. B. als aufsaugendes Mittel in Trockenelementen oder Sammlern fürgalvanischen Strom) oder aber nach Beseitigung des G.elzustandes zu anderen Zwecken, zu denen poröse Massen Verwein, dung finden. Durch Anwendung des Gel wird die Gesamtflüssigkeit so zäh, daß das Erstarrungsmaterial nicht zu Boden sinkt und es auch möglich wird, zur Erhöhung der Parosität in üblicher Weise Luftblasen einzubringen Beispiel g Getreidestärke werden in i a g Wasser durch Wärme- oder chemische Behandlung in einen Gelzustand gebracht und alsdann mit 70 g Wasser verrührt. Ohne daß eine Lösung der Stärke in dem Wasser erfolgt, wird die Gesamtflüssigkeit zäh und hält hinzugefügten Gips in der Schwebe, sie kann so in Formen .gegossen werden. - Nach Erstarrung des Gipses ist die Masse nicht mehr gießbar, der Grad der Festigkeit hängt natürlich von der Menge des zugefügten Gipses ab. Es gelingt aber z. B. mit ro % Gips (auf die Gesamtmenge des Wasser-Stärke-Gemisches gerechnet), eine genügende Festigkeit zu erzielen.Process for the production of porous artificial stone masses A large number of processes for the production of porous artificial stone masses are known : The method on which the invention is based overcomes these difficulties. The essence of the process is that in the liquid agent required for solidification, usually water, a gel floats more or less finely divided in such an amount that the free liquid only fills the spaces between the gel pieces. The prerequisite is, of course, that the gel itself does not dissolve in the liquid. If a material that absorbs the liquid for setting is now added, it solidifies in the interstices between the gel particles to form a sponge-like porous structure. This structure can either be used in the state of origin itself (e.g. as an absorbent medium in dry elements or collectors for galvanic current) or, after the elimination of the oil state, for other purposes, for which porous masses are transformed. By using the gel, the total liquid becomes so viscous that the solidifying material does not sink to the bottom and it is also possible to introduce air bubbles in the usual way to increase the parosity then stirred with 70 g of water. Without the starch dissolving in the water, the total liquid becomes viscous and keeps the plaster of paris added in suspension, so it can be poured into molds. - After the plaster of paris has solidified, the mass can no longer be poured; the degree of strength naturally depends on the amount of plaster of paris added. But it succeeds z. B. with ro% gypsum (calculated on the total amount of the water-starch mixture) to achieve sufficient strength.
