   Dünnere Beimengungen mit einem Überschuss an Wasserglas wären zu dem angegebenen Zweck schon aus dem Grunde nicht tauglich, weil das Wasserglas bekanntlich in der Wärme schon mit   350 C   zu   Blasenbildumgen   neigt. Die Erfindung ermöglicht die Herstellung von ganz dünnen Plattten ab 20 mm von solcher Festigkeit, dass sie für jeden beliebigen Bauzweck verwendet werden können. Dünne Platten von derartiger Festigkeit konnten noch bei keinem ähnlichen Verfahren erzielt werden. Dies

   Thinner admixtures with an excess of water glass would not be suitable for the stated purpose for the reason that, as is well known, the water glass tends to form bubbles when heated at 350 ° C. The invention enables the production of very thin plates from 20 mm of such strength that they can be used for any construction purpose. Thin plates of this strength have never been obtained by any similar process. This

formen erzielt, da bei Benutzung geschlossener Formen die Feuchtigkeit nicht entweichen könnte. Würden nicht gelochte Formen verwendet werden, dann wäre auch die Behandlung des oben angeführten Breies erfolglos. Die Durchführung des Verfahrens würde dabei ausserdem eine lange Zeit in Anspruch nehmen. Forms achieved, since when using closed forms, the moisture cannot escape. If non-perforated shapes were used, the treatment of the above-mentioned pulp would also be unsuccessful. The process would also take a long time to complete. Nicht minder wichtig ist die wärmetechnisch Behandlung des Materials selbst, da erprobt wurde, dass das Material umso vollwertiger wird, je genauer man die schon oben angeführten Temperaturen einhält. Geringere Wärmezuführungen würden nur ein Austrocknen des Materials mit verminderter Qualität zur Folge haben. No less important is the thermal treatment of the material itself, as it has been tested that the material becomes more fully-fledged the more precisely one adheres to the temperatures mentioned above. Lower heat input would only result in the material drying out with reduced quality. Das leichte Raumgewicht von zirka 200 leg bis 280 kg pro Kubikmeter mit höherer Festigkeit, die durch die Eigenartigkeit des Materials bedingt wird, wird von keinem Stoff mit annähernd gleichem Gewicht erreicht. Je nach Anwendungszweck und Art der herzustellenden Stoffe werden die organischen Fasern eventuell gegen Säureeinflüsse imprägniert oder es erhält der verwendete Brei entsprechend chemische Zusätze. Für den Eälteschutz od. dgl. werden die fertigen Produkte in Teerpräparate getaucht und mit einem geeigneten Überzug versehen. The light density of around 200 legs to 280 kg per cubic meter with higher strength, which is due to the peculiarity of the material, cannot be achieved by any material with approximately the same weight. Depending on the application and the type of materials to be produced, the organic fibers may be impregnated against the effects of acids or the pulp used may be given chemical additives. For protection against aging or the like, the finished products are dipped in tar preparations and given a suitable coating. PATENT-ANSPRUCH : Verfahren zur Herstellung hochporöser, feuersichere Bau-und Isolierkörper unter Verwendung von faserigen organischen Stoffen, wie Holzwolle, Stroh, Schilf u. dgl., und einer Wasserglas enthaltenden wässerigen Emulsion verschiedener Stoffe, wie Ton, Asbestmehl usw., dadurch gekennzeichnet, dass ein Gewichtsteil faserigen organischen Materials mit sechs Gewichtsteilen einer Emulsion überzogen werden, die aus gleichen Teilen wässeriger Wasserglaslösung von 32 bis 36 Be und darin fein verteilten Stoffen, wie Asbestmehl, Talkum, gebranntem Schieferton, gemahlene Schlacke usw., besteht, worauf die so hergestellten Rohmassen in allseits gelochten Blechformen einer Pressung und einem je nach der Stärke des herzustellenden Körpers % bis 2 Stunden dauernden Vortrocknungsprozess bei 200 C unterworfen werden, PATENT CLAIM: Process for the production of highly porous, fire-proof structural and insulating bodies using fibrous organic materials such as wood wool, straw, reeds and the like. Like., and an aqueous emulsion containing water glass of various substances, such as clay, asbestos flour, etc., characterized in that one part by weight of fibrous organic material is coated with six parts by weight of an emulsion, which consists of equal parts of aqueous water glass solution of 32 to 36 Be and therein fine distributed materials, such as asbestos flour, talc, burnt slate, ground slag, etc., whereupon the raw materials produced in this way are subjected to a pressing process in sheet metal forms perforated on all sides and a pre-drying process at 200 C, which lasts from% to 2 hours, depending on the strength of the body to be produced, sodann entformt und schliesslich bei 120 C fertig getrocknet werden. then removed from the mold and finally dried at 120 C to finish.
