Plastische Dichtungsmassen, wie sie insbesondere zum Abdichten in Stopfbüchsen dienen, enthalten vielfach körniges Material, insbesondere Kohlekörner und kleine Bruchstücke aus Kohle, wie sie z. B. zur Stromabnahme bei Motoren benutzt werden. Es sind dies Bruchkörner aus massivem, porenfreiem Material mit glatten Flächen, scharfen Kanten und Spitzen. Diese Körner bilden in der Dichtungsmasse die Gerüstkörper für die sie umgebende Graphitpaste.Plastic sealing compounds, such as those used in particular for sealing in stuffing boxes, often contain granular material, in particular grains of coal and small fragments of coal, such as those found, for. B. can be used to draw power in motors. These are broken grains made of solid, pore-free material with smooth surfaces, sharp edges and points. In the sealant, these grains form the framework for the graphite paste surrounding them.
Die Erfahrung hat nun gezeigt, daß diese scharfkantigen, massiven Körner die abzudichtenden Flächen, z. B. eine mit hoher Geschwindigkeit umlaufende Welle, leicht angreifen. Weiterhin ist auch die Bindung der Körner mit der sie umgebenden Graphitpaste infolge der glatten Flachen der Körner mangelhaft.Experience has now shown that these sharp-edged, massive grains form the surfaces to be sealed, z. B. easily attack a rotating shaft at high speed. Furthermore, there is also the bond the grains with the graphite paste surrounding them are deficient due to the smooth surfaces of the grains.
Erfindungsgemäß werden diese Mangel dadurch behoben, daß statt der bisher gebräuchlichen Körner, poröse, schwammartige Körper verwandt und der Dichtungsmasse einverleibt werden. Diese porösen, schwammartigen Körper haben weder scharfe Kanten und Ecken noch glatte Flächen. Sie können daher z. B. die Welle nicht ankratzen. Auch sind sie mit der Graphitpaste engstens verbunden, da die Paste in die Poren eingedrückt wird und die porösen Körner gleichsam durchdringt.According to the invention, these deficiencies are remedied by that instead of the previously used grains, porous, sponge-like bodies related to the sealing compound be incorporated. These porous, sponge-like bodies have neither sharp edges and corners still smooth surfaces. You can therefore z. B. do not scratch the shaft. Also they are with the graphite paste closely connected, as the paste is pressed into the pores and the porous grains as it were penetrates.
Die Kohlenmasse wird in der allgemein bekannten Art, z. B. durch Mischung von Ruß und Teer, gegebenenfalls unter Zugabe weiterer Bestandteile, wie Wasserglas, Graphit usw., hergestellt. Aus einer derartigen entsprechend gebrannten Masse erhielt man bisher durch Zerkleinerung die der Dichtungsmasse einzuverleibenden harten Körner.The coal mass is in the well known manner, e.g. B. by mixing soot and tar, if necessary with the addition of other components such as water glass, graphite, etc. From such a Correspondingly fired mass has hitherto been obtained by crushing that of the sealing mass hard grains to be incorporated.
Erfindungsgemäß verfährt man so, daß man der teigförmigen Masse vor dem Brennen Gase in feiner Verteilung zuleitet oder sie mit Gase erzeugenden Chemikalien oder mit unter geringer Aschebildung ver-The procedure according to the invention is such that the dough-like mass is finely gassed before firing Or with chemicals that generate gases or with little ash formation.
brennbaren, ft in vci teilten Köipern, z. B. feinem Sägemehl, versetzt. Beim Brennen einer solchen Masse entsteht dann ein mit zahlreichen Poren durchsetzter schwammartiger Körper. Beim Brennen einer mit feinem Sägemehl versetzten Masse erzeugt z. B. jedes einzelne Teilchen des Sägemehls einen kleinen Hohlraum, so daß die ganze Masse von solchen Hohlräumen durchsetzt ist.combustible bodies divided into vci, e.g. B. fine Sawdust, offset. When such a mass is fired, one with numerous pores is created spongy body. When burning a mass mixed with fine sawdust z. B. each individual particles of sawdust create a small cavity, so that the whole mass of such cavities is interspersed.
Die gebrannten Brocken können leicht zerkleinert und auf Korngröße gesiebt werden, worauf diese porösen Körner anstatt der bisherigen harten Bruchkörner bei der Herstellung plastischer Dirhtungsmassen verarbeitet werden können.The burnt lumps can easily be crushed and sieved to grain size, whereupon they become porous Grains instead of the previous hard broken grains in the production of plastic directional masses can be processed.
In einer abgeänderten Ausführungbform des beschriebenen Verfahrens kann die mit Gase bildenden Chemikalien oder mit Sägemehl durchsetzte Masse durch ein Sieb getrieben werden, worauf die durchgesiebten Teilchen gebrannt und dann nochmals auf Korngröße gesiebt werden.In a modified embodiment of that described The process can involve chemicals which form gases or the mass interspersed with sawdust are driven through a sieve, whereupon the sieved particles are burned and then again on Grain size to be sieved.
Das beschriebene Verfahren läßt sich mannigfach abändern oder ausgestalten, so z. B. in bezug auf die Zusammensetzung der zur Herstellung der porösen Körner dienenden Giundmast-i., den Zusatz an Gasen, Chemikalien oder brennbaren Stoffen, die Erbitzungsdauer usw. Ebenso kann die weitere Verarbeitung der erhaltenen porösen Körner in den plastischen Dichtungsmassen in verschiedenster Weise durchgeführt werden.The method described can be varied or designed in many ways, such. B. with respect to the Composition of the Giundmast-i. Used for the production of the porous grains, the addition of gases, Chemicals or flammable substances, the duration of the acquisition etc. Likewise, the further processing of the porous grains obtained in the plastic sealing compounds can be carried out in a wide variety of ways.
