Description
Verfahren zur Herstellung von porösen keramischen Bauelementen Es ist bei der Herstellung von Mauersteinen od. dgl. schon bekannt, dem Ton brennbare organische Stoffe, wie Sägespäne, Torf, Kohlenstaub, zuzufügen, der dann geformt, getrocknet und gebrannt wird, wodurch man Ziegel erhält, welche porös und leicht sind. Das Volumgewicht solcher Ziegel liegt im allgemeinen zwischen ungefähr i,i bis 1,6, ist aber von den verwendeten Tonsorten und der Menge der eingemischten brennbaren Stoffe abhängig. Aus praktischen Gründen kann man das Volumgewicht nicht unter die Grenze von i,i bis 1,2 herabsetzen, teils wegen der verminderten Formbarkeit des Tons bei allzu großem Zusatz pulveriger, brennbarer Stoffe mit großen Reibungsflächen, teils wegen des daraus folgenden geringen Druckwiderstands des Ziegels. Die bei den jetzigen Herstellungsmethoden poröser Ziegelwaren angewandte Feinverteilung der brennbaren Stoffe bewirkt eine große Anzahl dicht gegeneinanderliegender Poren von einer solchen Größe, daß ein Produkt mit großer Kapillarität und sehr geringer Widerstandsfähigkeit gegen Frost entsteht.Process for the production of porous ceramic components Es is in the production of bricks or the like. Already known, the clay combustible adding organic substances such as sawdust, peat, coal dust, which is then formed, dried and fired to give bricks which are porous and light are. The volume weight of such bricks is generally between approximately i, i up to 1.6, but depends on the types of clay used and the amount of mixed in depending on flammable substances. For practical reasons one cannot determine the volume weight below the limit of i, i to 1.2, partly because of the reduced malleability of the clay when too much powdery, flammable substances with large friction surfaces are added, partly because of the resulting low pressure resistance of the brick. The at Fine distribution applied to the current production methods of porous brick goods of the combustible substances causes a large number of closely spaced pores of such a size that a product with great capillarity and very little Resistance to frost arises.
Um Bauelemente von größerer Widerstandsfähigkeit herzustellen, bildet man gemäß dem Verfahren nach vorliegender Erfindung Formkörper aus in feinzerkleinertem Zustand befindlichem brennbarem Stoff. Diese Formkörper werden mit Ton vermischt, und aus diesem Gemisch werden Bauelemente geformt, welche getrocknet und gebrannt werden.In order to produce components of greater resistance, forms according to the process according to the present invention, moldings are made from finely comminuted The state of the combustible material. These moldings are mixed with clay, and from this mixture building elements are formed, which are dried and fired will.
Vor der Mischung des Tons mit den Formkörpern kann er gemagert werden, z. B. durch Vermischen mit Sand. :- Das Verfahren gemäß vorliegender Erfindung wird nachstehend beispielsweise näher erläutert. ' Um in den Bauelementen Poren von gewünschter Form zu erhalten, bildet man mit dem brennbaren, pulverförmigen Stoff, z. B. mit Sägemehl, Torf, Kohlenstaub oder auch mit Mischungen dieser Stoffe, Körper von regelmäßiger geometrischer Form, z. B. kugel-, ellipsoid-, stab- oder kubus= förmig. Dazu kann ein Bindemittel verwendet werden, wie Methylcellulose.Before the clay is mixed with the moldings, it can be made leaner, z. B. by mixing with sand. : - The procedure according to this The invention is explained in more detail below, for example. 'To in the building elements To obtain pores of the desired shape, one forms with the combustible, powdery Fabric, e.g. B. with sawdust, peat, coal dust or with mixtures of these substances, Bodies of regular geometric shape, e.g. B. spherical, ellipsoidal, rod or cube = shaped. A binder such as methyl cellulose can be used for this purpose.
Die Abmessungen der Formkörper aus brennbarem Stoff in den drei Dimensionen werden in der Praxis so gewählt, daß keine geringer ist als '2 _mm und keine größer ist als 8 mm.The dimensions of the molded bodies made of combustible material in the three dimensions are chosen in practice so that none is less than '2 _mm and none is greater is than 8 mm.
Durch dieses Verfahren wird erreicht, daß die Poren bedeutend weniger zahlreich,.dafür aber grö-. Ber sind, was eine bestimmte Porosität hervorruft. Die Poren werden nämlich voneinander mehr abgegrenzt und sind nicht kapillar. Die Reibungsoberflächen der eingemischten Körper sind beträchtlich kleiner als bei Einmischung einer entsprechenden Menge z. B. von Sägemehl oder ände@em brennbaren pulverförmigen Material, und der Ton behält somit eine gute Formbarkeit. Das Endprodukt besitzt eine sehr erhöhte Festigkeit und Frostbeständigkeit bei gleicher oder erhöhter Porosität. Wenn die brennbaren, dem Ton zugefügten Körper eine stabähnliche oder längliche' Form aufweisen, so richten sie sich, z. B. in einer - Ziegelstrangpresse, beim Auspressen der Tonmenge durch ein Mundstück -mit ihren Längsachsen in der Längsrichtung des Stranges aus. Im Endprodukt stehen infolgedessen die Längsachsen der Poren senkrecht zu den großen Flächen oder 'Auflageflächen der Backstein, was für die Widerstandskraft der Steine von Vorteil ist.This process ensures that the pores are significantly fewer numerous, but larger. Ber are what causes a certain porosity. the This is because pores are more delimited from one another and are not capillary. The friction surfaces the interfering bodies are considerably smaller than when interfering with a corresponding one Amount z. B. of sawdust or änd @ em combustible powdery material, and the Clay thus retains good malleability. The end product has a very increased Strength and frost resistance with the same or increased porosity. If the combustible bodies added to the clay have a rod-like or elongated shape, so they align, z. B. in a brick extruder, when pressing out the amount of clay through a mouthpiece -with their longitudinal axes in the longitudinal direction of the strand. As a result, in the end product the longitudinal axes of the pores are perpendicular to the large ones Surfaces or 'contact surfaces of the brick, what for the resistance of the stones is beneficial.
Bei gewissen Bausteinen ist es nicht wünschenswert, daß die aus denbrennbaren Körpern entstehenden Poren in den Oberflächen der Steine sichtbar sind; dies kann aber dadurch vermieden werden, daß die Körper durch eine Vorrichtung in den Tonstrang hineingeschoben' werden.In the case of certain building blocks, it is not desirable that those made from the combustible Pores arising in the body are visible in the surfaces of the stones; This can but this can be avoided that the body through a device in the clay strand be pushed in '.
Die geformten brennbaren Körper werden somit unter innig mechanischer gemischt. Die Bearbeitung Formkörper mit sind dem rohen bezüglich Tön--' ].Form und Größenordnung genau unterteilt, und die Menge wird je nach dem gewünschten spezifischen Gewicht und der Widerstandsfähigkeit des Endprodukts gewählt.The formed combustible bodies are thus under intimately mechanical mixed. The processing of moldings with are the raw with respect to Tön-- '] .Form and order of magnitude precisely divided, and the amount will be specific depending on the desired Weight and resistance of the final product.
Der so@-gemischte Ton wird danach in bekannter Weise geformt und dann gebrannt.The so @ -mixed clay is then shaped in a known manner and then burned.
