Description
Verfahren zur Herstellung eines hochporösen, feuerfesten Isolier- und Baumaterials und Einrichtung zu dessen Durchführung. Es ist bereits bekannt, Bau- und Isolier- körper unter Verwendung von faserigen, or ganischen Stoffen, wie Holzwolle, Stroh, Schilf und dergleichen unter Zuhilfenahme von verschiedenen staubartigen Stoffen, wie Ton, Asbestmehl usw., die zusammen durch ein Bindemittel versteinert werden, her zustellen.
Die vorliegende Erfindung beruht nun mehr auf einem neuen Verfahren zur Her stellung eines hochporösen, feuerfesten Iso- lier- und Baumaterials, bei welchem gleich falls die obgenannten Stoffe verwendet wer den, jedoch in besonderer Zusammensetzung, und zwar werden bei drei Gewichtsteilen faserigen Rohmaterials zirka 5 bis 7,5 Ge wichtsteile staubartigen Rohstoffes verwen det, wobei als Bindemittel zirka 5 bis 7,5 Gewichtsteile Wasserglas in flüssiger Form in einer Konzentration von zirka d6 bis<B>38'</B> Be verwendet werden.
Besonders geeignet für das Verfahren sind neben Holzwolle, Stroh, Schilf oder dergleichen auch Ampas (Zuckerrohrabfälle), Bast, getrocknete Gräser usw. Als staubartige Rohstoffe können vor teilhaft Kaolinschlicker, Sand und derglei- ehen verwendet werden.
Das ,so erhaltene Gemenge wird in allseits gelochte Blechformen geprellt und ge trocknet.
Das fertige Material besitzt einen sehr hohen Isolierwert..
Eine weitere Verfahrensmassnahme, die bei der Herstellung poröser. Kunststeine bereits angewendet wurde, kann :darin bestehen, dass man das Material an den Rändern stärker presst, um eine scharfe Kantenbildung trotz sperriger Eigenart des Stoffes, zu erzielen. Die Verstärkung der Ränder wird durch Verdichtung,des porösen Materials erzielt.
In den Figuren der Zeichnung ist eine Ein richtung zum Pressen :des Materials, bei der Durchführug des oben beschriebenen Verfah rens dargestellt, und zwar zeigt Fig.1 die Ein- richtung von oben gesehen, Fig. 2 einen Teil schnitt derselben und Fig. 3 die Form im Schnitt nach Beendigung,des Pressvorganges. Wie aus den Figuren hervorgeht, wird der Pressvorgang zwischen einem gelochten Boden- blecha und einem ebensolchen Deckblech b aua geführt.
Zwischen diesen beiden Blechplatten befinden sieh zwei längere Blechleisten c und zwei kürzere Blechleisten d, die im Steg gelocht und U-förmig .gebogen sind. Eine durch diese Teile gebildete Pressvorrichtung kann durch Klammern e zusammengehalten werden,welche dasBoden-un.dDeckblech über greifen. Nach Einfüllen des Materials in die Form unter Benützung eines Flilfsrahmens g wird das Deckblech b aufgelegt und durch Druck auf dieses von oben bis zum Aufsitzen auf die U-Leisten c das Material gepresst.
So dann wird durch Seitendrücke auf .die vier Leisten c und d eine Verschiebung der letz teren durch Druck bewerkstelligt, so dass eine Stauung .des Materials in den Randleisten (zirka um 15 mm allseits) mit gleichzeitigem Schliessen .der Formen durch Übergreifen. der Klammern e. auf das Boden- und Deckblech b bezw. a erfolgt. Sodann wird die Form auf dem Rollgang f einem Ofen zur wärme technischen Behandlung des Materials zu gerollt.
Process for the production of a highly porous, fireproof insulating and building material and device for its implementation. It is already known to build building and insulating bodies using fibrous, organic materials such as wood wool, straw, reeds and the like with the aid of various dust-like substances such as clay, asbestos flour, etc., which are petrified together by a binding agent, manufacture.
The present invention is now based more on a new method for the manufacture of a highly porous, fire-resistant insulating and building material, in which the above substances are also used, but in a special composition, namely about 5 parts by weight of fibrous raw material Up to 7.5 parts by weight of dust-like raw material are used, with about 5 to 7.5 parts by weight of water glass being used in liquid form in a concentration of about d6 to <B> 38 '</B> Be as the binding agent.
In addition to wood wool, straw, reeds or the like, ampas (sugar cane waste), bast, dried grass, etc. are particularly suitable for the process. Kaolin slip, sand and the like can be used as dust-like raw materials.
The mixture obtained in this way is bounced into sheet metal forms perforated on all sides and dried.
The finished material has a very high insulation value.
Another procedural measure involved in making porous. Artificial stone has already been used can: consist in pressing the material harder at the edges in order to achieve sharp edges despite the bulky nature of the material. The edges are reinforced by compressing the porous material.
In the figures of the drawing, a device for pressing: the material is shown during the implementation of the above-described method, namely FIG. 1 shows the device viewed from above, FIG. 2 a part section of the same and FIG the shape in the section after completion of the pressing process. As can be seen from the figures, the pressing process is carried out between a perforated base plate and a cover plate of the same type.
Between these two sheet metal plates are two longer sheet metal strips c and two shorter sheet metal strips d, which are perforated and U-shaped in the web. A pressing device formed by these parts can be held together by clamps e, which grip the base and cover plates. After the material has been poured into the mold using a auxiliary frame g, the cover plate b is placed and the material is pressed by pressing it from above until it sits on the U-strips c.
By pressing the sides on the four strips c and d, the latter is then shifted by pressure, so that the material is stowed in the edge strips (about 15 mm on all sides) with simultaneous closing of the forms by reaching over. of the brackets e. on the bottom and cover plate b respectively. a takes place. The form is then rolled on the roller table to an oven for the thermal treatment of the material.
