Description
Verfahren zur Herstellung poröser Körper Die Erfindung betrifft ein Verfahren zur Herstellung poröser (schaumartiger) Körper aus Holzfaserstoffen und Bindemitteln. Die bekannten Verfahren bestehen darin, daß Sägemehl, Torf oder andere Holzfaserstoffe mit der natürlichen Zellulose oder hydraulischen, natur- und kunstharzhaltigen, bituminösen, leim- oder metallsalzhaltigen Bindemitteln zu lockeren bis steinartigen Körpern gebunden werden.Method of making porous bodies The invention relates to a Process for the production of porous (foam-like) bodies from wood fibers and Binders. The known methods are that sawdust, peat or other Wood fibers with the natural cellulose or hydraulic, natural and synthetic resin containing, bituminous, glue or metal salt-containing binders to loose to stone-like Bodies are bound.
Bei einigen Verfahren, insbesondere solchen, die hydraulische Bindemittel in Verbindung mit anderen Mineralien benötigen, muß vor dem eigentlichen Bindeprozeß eine Mineralisierung der Holzfaserstoffe durchgeführt werden.In some processes, especially those that use hydraulic binders in connection with other minerals, must before the actual binding process a mineralization of the wood fibers can be carried out.
Der Bindeprozeß der Holzfaser einschließlich der Bindemittel erfolgt entweder unter Druck, mit oder ohne Wärmezuführung, oder im Schüttguß. Hierbei wird die lockere bis dichte Struktur der herzustellenden Körper aus Holzfaserstoffen geregelt durch die Wahl von fein- oder grobspanigen sowie langfaserigen, in sich verschlungenen Holzfasern, den mehr oder weniger zuzusetzenden Bindemitteln zur Holzfasermasse von erdfeuchter bis flüssiger Konsistenz oder .auch durch den gesteuerten Preßdruck.The binding process of the wood fiber including the binding agent takes place either under pressure, with or without the supply of heat, or in bulk pouring. Here is the loose to dense structure of the bodies to be produced from wood fiber materials regulated by the choice of fine or coarse-chipped as well as long-fiber ones entangled wood fibers, the more or less to be added binders Wood fiber mass from earth-moist to liquid consistency or also through the controlled Press pressure.
Die Herstellung solcher lockeren bis steinartigen Körper aus Holzfaserstoffen wird in vielen Fällen durch teure Bindemittel erreicht, auch sind vielfach komplizierte Arbeitsvorgänge und umfangreiche Fabrikationseinrichtungen, wie Pressen, Heizvorrichtungen mit hohem Wärmeenergieverbrauch usw., erforderlich.The production of such loose to stone-like bodies from wood fiber materials is achieved in many cases using expensive binders, and they are often complex Work processes and extensive manufacturing facilities, such as presses, heating devices with high thermal energy consumption, etc., is required.
Die Erfindung besteht darin, daß poröse Körper aus Holzfaserstoffen, wie Sägemehl, Torf, zerkleinertes Stroh, Schilf, Baumrinde u. a., mit einer schaum- oder schwammartigen Struktur hergestellt werden, derart, daß die Holzfaserstoffe mit einem Mineral, wie Kieselgur, Kreide oder Bimsmehl, in feinster Körnung und einem bekannten Schaumerzeuger trocken vermischt werden. Dann wird die Mischung mit Wasser erdfeucht angereichert.The invention consists in that porous bodies made of wood fibers, such as sawdust, peat, crushed straw, reeds, tree bark, etc., with a foam or sponge-like structure can be produced in such a way that the wood fibers with a mineral such as diatomaceous earth, chalk, or pumice powder, in finest Granule and a known foam generator are dry mixed. Then the Mixture enriched with earth moist water.
Hierdurch bindet sich das Mineral, wie Kieselgur; Kreide oder Bimsmehl, locker an die Holzfaserstoffteilchen. In diesem Zustand wird der Mischung ein erhärtendes Mittel, wie kieselsaures Natrium, so lange zugegossen, bis sich eine dickflüssige Masse ergibt, die nun so lange gerührt oder geschlagen wird, bis sich eine schaumige -Masse gebildet hat, die dann in der gewünschten Weise verarbeitet wird.This binds the mineral like kieselguhr; Chalk or pumice powder, loosely on the wood fiber particles. In this state the mixture becomes a hardening one Agents, such as sodium silicate, are poured in until it becomes thick and viscous The result is a mass that is stirred or beaten until it is frothy -Mass has formed, which is then processed in the desired way.
Hierdurch wird erreicht, daß die Holzfaserstoffteilchen zunächst durch die trockene Vermischung unmittelbar mit einem Mineral in Bohrung gebracht und durch den Zusatz von Wasser locker miteinander verbunden werden. Dieser Vorgang macht eine vorherige M neralisierung der Holzfaserstoffe überflüssig. Der nachfolgende Zuguß von kieselsaurem Natrium umhüllt die beiden Stoffteile Holzfaser-Miner'al, und das Schaummittel lockert durch Blasenbildung infolge von Rühren oder Schlagen die bis dahin dickflüssige Masse in eine schaumartige Struktur. Durch die Verwendung von kieselsaurem Natrium und einem Mineral entsteht während des Trockenprozesses ein. Verkieselungsskelett, in dem ,die überwiegend vorhandenen Holzfaserstoffe eingebettet sind.This ensures that the wood fiber particles initially through the dry mixture brought directly into the bore and through with a mineral the addition of water can be loosely connected. This process makes a prior mineralization of the wood fibers is superfluous. The following Addition of silicic acid sodium envelops the two pieces of wood fiber-mineral, and the foaming agent loosens by bubbling due to stirring or beating the previously viscous mass into a foam-like structure. By using of silica and a mineral is formed during the drying process a. Silicification skeleton in which the predominantly existing wood fibers are embedded are.
Die Dichte des Porenraumes wird reguliert durch den Zusatz einer bestimmten Wassermenge in die Trockenmischung und dem mengenmäßigen Anteil eines Schaumerzeugers.The density of the pore space is regulated by the addition of a certain Amount of water in the dry mix and the quantitative proportion of a foam generator.
Der Härtegrad des Verkieselungsskeletts wird während des Mischprozesses geregelt durch einen größeren oder kleineren Anteil eines Minerals zur Faserstoffmenge.The degree of hardness of the silicification skeleton is determined during the mixing process regulated by a larger or smaller proportion of a mineral in the amount of fiber.
Durch den Zusatz eines wasserabweisenden Bitumens, z. B. Ceres-it, werden die porösen Körper unempfindlich gegen Feuchtigkeit.By adding a water-repellent bitumen, e.g. B. Ceres-it, the porous bodies become insensitive to moisture.
Die statische Druck- und Biegefestigkeit wird erhöht durch Zumischung von -grob- oder langfaserigen Stoffen.The static compressive and flexural strength is increased by adding it of coarse or long-fiber fabrics.
Zur Herstellung farbiger Körper in allen Tönungen sowie Mischfarben kann Farbpulver aller Art der Trockenmischung zugesetzt werden.For the production of colored bodies in all tints as well as mixed colors Color powder of all kinds can be added to the dry mix.
Das Verfahren ermöglicht es, durch Schichtguß oder Vollguß lineare oder plastische Körper, d. h. Körper in jeder Form und auch Blöcke und Platten in jeder gewünschten Länge, Breite und Höhe herzustellen und diese durch Lufttrocknung, Abwärmetrockenkammern oder Hochfrequenztrocknung zu erhärten. Blöcke können am Sägegatter zu Platten nuseinandergesägt werden. Desgleichen ist es möglich, die Schaumholzmasse auf Wände und Decken aufzutragen oder als Schutz-, Isolier- oder Zierstoffauflage für Glas, Keramik, Stahl, Metall, Naturholz, Pappe, Leder und andere feste Stoffe zu verwenden.The process makes it possible to produce linear by layer casting or full casting or plastic bodies, d. H. Body in every shape and also blocks and plates in to produce any desired length, width and height and these by air drying, To harden waste heat drying chambers or high-frequency drying. Blocks can be attached to the saw frame be sawn together to form panels. It is also possible to use the foam wood mass To be applied to walls and ceilings or as a protective, insulating or decorative layer for glass, ceramics, steel, metal, natural wood, cardboard, leather and other solid materials to use.
Bei Anwendung des Verfahrens in vorbeschriebener Weise können zusätzlich der genannten Mineralien, wie Kieselgur, Kreide oder Bimsmehl, auch Selbstbinder, wie Zement, Kalk oder Gips, mitverwendet werden. Desgleichen kann dem kieselsauren Natrium im verschaumten Zustand ein anderes Bindemittel aus Leim, Harz Bitumen oder Metallsalze zugesetzt werden.When using the method in the manner described above, in addition the mentioned minerals, such as kieselguhr, chalk or pumice powder, also self-binders, such as cement, lime or gypsum can also be used. Silica can also do the same Sodium in the foamed state is another binder made from glue, bitumen or resin Metal salts are added.
Das erfindungsgemäße Verfahren zur Herstellung poröser Körper hat gegenüber den bekannten Verfahren den Vorteil, daß Holzfaserstoffe und Abfälle aller Art wieder zu porösen, aber festen Körpern verbunden werden mit Bindemitteln, die in ausreichendem Maße vorhanden und darum sehr billig sind.The method according to the invention for producing porous bodies has compared to the known method has the advantage that wood fibers and waste all Kind of again to be connected to porous, but solid bodies with binders that available in sufficient quantities and therefore very cheap.
Dazu kommt der einfache Mischvorgang mit dem nachfolgenden Einguß in die vorbereiteten Formen. Ein Arbeitsvorgang, der mit wenigen Arbeitsgeräten und Hilfskräften durchgeführt werden kann. Der Trockenprozeß erfordert nur geringe Wärme oder Abwärmetemperatur.In addition, there is the simple mixing process with the subsequent pouring into the prepared forms. A work process that requires few tools and assistants can be carried out. The drying process requires little Heat or waste heat temperature.
