Description
Verfahren der Herstellung von Kunststein unter Verwendung kolloidaler, gebundener oder freier Kieselsäure als Bindemittel und Erhärtung durch Wasserentziehung sowie Anwendungsart dieses Verfahrens. Die Erfindung geht von der Tatsache aus, daßKieselsäure und kieselsaure Verbindungen durch Wasserdampf bei genügend hohen Temperaturen und Dannpfdrudc und genügend langer Einwirkung nicht nur teilweise zur Ouellung, sondern sogar zur völligen (kolloidalen) Lösung gebracht werden können, wobei sich eine mehr oder weniger dickflüssige Gallerte bildet. Durch Wasserentziehung infolge Verdunstung oder durch Behandlung mit Wasser entziehenden Stoffen (z. B. Alkohol, Azeton), durch Behandlung mit konzentrierten Lösungen, quellungshemmender Salze (z. B. Alaun, Tonerdesulfat und Sulfate überhaupt) oder durch Gerbmittel (z. B. Chromsäure, Formaldehyd) kann die gallertartige Substanz wieder in die feste Form gebracht werden.Method of making artificial stone using colloidal, Bound or free silica as a binding agent and hardening through dehydration as well as the type of application of this procedure. The invention is based on the fact that silicic acid and silicic acid compounds by water vapor at sufficiently high Temperatures and then pressure and sufficiently long exposure not only partially can be brought to the ouelling, but even to the complete (colloidal) solution, a more or less thick jelly forms. By dehydration as a result of evaporation or treatment with substances that remove water (e.g. Alcohol, acetone), by treatment with concentrated solutions, anti-swelling Salts (e.g. alum, alumina sulphate and sulphates in general) or by tanning agents (e.g. B. chromic acid, formaldehyde) can the gelatinous substance back into the solid Be brought into shape.
Es handelt sich: bei der vorliegenden Erfindung im Gegensatz zu bekannten Verfahren nicht um; ein Plastischmachen von Silikaten durch Dampfbehandlung, noch um die Erzeugung kolloider Kieselsäure durch irgendwelche Agentien, z. B. Salzsäure, Salpetersäure, Schwefelsäure, Alkalien, alkalische Erden, Fluorverbindungen usw., durch welche die Kieselsäure teils für sich, teils in Verbindung reit den betreffenden Agentien in die kolloidale Form übergeführt wird, sondern -um die Bildung kolloiden Bindemittels aus Kieselsäure oder Silikaten ausschließlich durch Behandlung mit Wasserdaxnpf ohne jeden weiteren Zusatz von irgendwelchen Agentien, die darawffolgende Benutzung dieser kolloiden Kieselsäure als Bindemittel und danach die Überführung des Kieselsäurehydrogels in festes Gel ausschließlich durch Wasserentziehung zum Zweck der Erhärtung.These are: the present invention as opposed to known ones Procedure not order; a plasticizing of silicates by steam treatment, still to generate colloidal silica by any agents, e.g. B. hydrochloric acid, Nitric acid, sulfuric acid, alkalis, alkaline earths, fluorine compounds, etc., through which the silica rides partly for itself, partly in connection with the person concerned Agents in the colloidal form is converted, but -to the formation of colloids Binding agent made of silica or silicates exclusively by treatment with Wasserdaxnpf without any further addition of any agents, the following Using this colloidal silica as a binder and then transferring it of the silica hydrogel in solid gel exclusively by dehydration Purpose of hardening.
Wird beispielsweise Quarzsand oder eine kieselsaure Verbindung (Ton, Schiefer usw.) im Autoklaven unter genügend hohem Dampfdruck so lange gedämpft, daß nur die Oberfläche der Körner gelatiniert, der Kern jedoch unverändert bleibt, so kann die so erhaltene Masse je nach denn Grad der Gelatinierung in Formen geblossen, gestampft oder gepreßt werden oder, auch wie Mörtel zur Verbindung größerer Baustoffe (Ziegel, Steinquadern) gebraucht werden, während die Erhärtung in dem Maße erfolgt, in dem das Dispersionsmittel aus dem Emulsoid verdunstet oder durch ein Trockrnungsmittel oder einen Gerbprozeß verdrängt wird.If, for example, quartz sand or a silica compound (clay, Slate etc.) steamed in the autoclave under sufficiently high steam pressure for so long that only the surface of the grains gelatinizes, but the core remains unchanged, the mass obtained in this way can, depending on the degree of gelatinization, be baked in molds, be tamped or pressed or, also like mortar for connecting larger building materials (Bricks, stone blocks) are used while the hardening takes place to the extent that in which the dispersant evaporates from the emulsoid or through a drying agent or a tanning process is displaced.
Eine andere Arbeitsweise ist die, die völlig oder, wenn auch unvollständig, so doch in zu diesem Zweck genügendem Maße, gelatinierte Masse mit geeigneten Füllstoffen (Quarzsand, Dolomitsand, Asbest, organischen Faserstoffen usw.) zu vermischen, auf die das aus der Kieselsäure oder den Silikaten gewonnene Emulsoid als ein mineralischer Leim wirkt. Die so erhaltene Masse wird nach diesem Verfahren durch Entziehen des Dispersionsmittels auf irgendeine vorher beschriebene Weise zur Erhärtung gebracht.Another way of working is that which completely or, even if incompletely, but to a sufficient extent for this purpose, gelatinized mass with suitable fillers (Quartz sand, dolomite sand, asbestos, organic fiber, etc.) to mix the emulsoid obtained from silicic acid or silicates as a mineral one Glue works. The mass obtained in this way is after this process by removing the Dispersant hardened in any manner previously described.
Zur Herstellung künstlicher Massen von glasartiger Beschaffenheit wird natürlich nur völlig gelatiniertes Silikat zur Verwendung konnrnen.For the production of artificial masses of more vitreous Naturally, only fully gelatinized silicate can be used.
