Description
Verfahren zur Herstellung von porösen Baustoffen. Die Erfindung betrifft ein Verfahren zur -Herstellung von porösen Stoffen für Bauzwecke u. dgl. aus Mineralstoffen, z. B. Zement und Gips, die mit Wasser oder anderen Flüssigkeiten gemischt werden. Die Erfindungbesteht darin, daß im Verein mit der Mischungsflüssigkeit Schaum zum " künstlichen Porösmachen des Materials verwendet wird. Es -hat sich nämlich herausgestellt, daß solcher Schaum während der nachfolgenden Formung des Materials hinlänglich haltbar ist, so daß in der Masse eine Menge von Luftblasen zurückbleiben-, welche ihre Porosität gewährleisten.Process for the production of porous building materials. The invention relates to a process for the production of porous materials for building purposes and the like from minerals, z. B. cement and plaster of paris mixed with water or other liquids. The invention consists in that, in association with the mixing liquid, foam for "artificial porosity of the material is used. It has been found that that such foam is sufficiently durable during the subsequent shaping of the material is so that a lot of air bubbles remain in the mass - which is its porosity guarantee.
Das Verfahren kann in der Weise durchgeführt werden, daß man einen schaumbildenden Stoff zu der Mischungsflüssigkeit oder zu einer Mischung von dieser Flüssigkeit und dem damit gemischten Material zusetzt, wonach die Schaumbildung durch ein kräftiges Umrühren oder durch Zufuhr von Druckluft, evtl. von Kohlensäure, hervorgebracht wird. In vielen Fällen ist es jedoch das einfachste, schon fertiggemachten Schaum zu der Mischungsflüssigkeit oder der Mischung von dieser Flüssigkeit und dem damit gemischten Material hinzuzufügen. Bei der Herstellung im größeren Maßstabe wird man dabei den Schaum in einer speziellen Maschine, von welcher --der Schaum zu einer \li.chun,:;smaschine von gewöhnlicher hnns'ru'.ai@@r. Über-P 0' führt wird. zubereiten. so daß der Schaum anstatt oder gleichzehig mit Sand oder anderen Füllstoffen i-i der Mischling aufgenommen wird.The process can be carried out in such a way that a foam-forming substance is added to the mixture liquid or to a mixture of this liquid and the material mixed therewith, after which the foam formation is brought about by vigorous stirring or by supplying compressed air, possibly carbonic acid will. In many cases, however, it is easiest to add already made foam to the mixture liquid or to the mixture of this liquid and the material mixed with it. When manufacturing on a larger scale, the foam is processed in a special machine, from which the foam becomes a \ li.chun,:; s machine from ordinary hnns'ru'.ai @@ r. Over-P 0 ' leads. prepare. so that the foam is absorbed instead of or at the same time as sand or other fillers ii the hybrid.
Als schaumbildender Stofft kann ein Pflanzenschleim-,- z. B. das von Tang oder Meergras hergestellte sol-enannte Tangin, dienen. Die Haltbarkeit des von diesen Stoffen hergestellten Schaumes kann durch Zusatz von Gelatine erhöht werden. Die von diesen Stoffen benötigten Mengen sind sehr gering, so daß das Verfahren sich sehr preiswert stellt.As a foam-forming substance, a plant slime -, - z. B. that of Seaweed or seaweed made sol-called tangin, are used. The durability of the Foam produced from these substances can be increased by adding gelatin will. The quantities of these substances required are very small, so the process presents itself very cheaply.
In gewissen Fällen hat man beobachtet, daß eine weitere Stärkung des Schaumes durch Zusatz von ein wenig Formaldehyd stattfindet.In certain cases it has been observed that a further strengthening of the Foam takes place by adding a little formaldehyde.
Außer den obengenannten Stoffen hat es sich herausgestellt, daß lösbare Seifen, z.-B. Harz-Natron- oder Harz-Kali-Seife, zu diesem Zwecke wohl seeigne: sind. Diese Seifen haben die Eigenschaf;, daß sie einen speziell starken und beständigen Schaum entwickeln, der sehr geei=gnet ist, mit den betonbildenden Materialien gernischc zu «erden, ohne daß die Schaumblasen _-ebrochen werden, so daß der gewünschte Porositätsrad ganz sicher erreicht «-erden kann.In addition to the above substances, it has been found that releasable Soaps, e.g. Resin-soda or resin-potash soap, probably useful for this purpose: are. These soaps have the property that they are particularly strong and durable Develop foam that is very suitable for mixing with the concrete-forming materials to "earth" without breaking the foam bubbles, so that the desired degree of porosity can be reached with certainty.
