Description
Titel: Verfahren zum Strangpressen von formbeständigen,Title: Process for the extrusion of dimensionally stable,
härtbaren Zementformkörpern Verfahren zum Strangpressen von formbeständigen, härtbaren Zementformkörpern üie Erfindung betrifft ein Verfahren zum Strangpressen von formbeständigen, härtbaren Zementformkörpern, bei dem ein Gemisch aus Zement, aus wenigstens einem Extrudierungshilfsmittel, aus wasseradsorbierenden Zuschlagstoffen sowie aus Wasser mit Hilfe eines extruders, z.B. mit Hilfe eines üblichen Kolben- oder Schneckenextruders extrudiert wird. hardenable cement moldings Method of extrusion of dimensionally stable, hardenable cement moldings üie invention relates to a method for the extrusion of dimensionally stable, hardenable cement moldings, in which a Mixture of cement, of at least one extrusion aid, of water-absorbing Aggregates as well as from water with the help of an extruder, e.g. with the help of a conventional piston or screw extruder is extruded.
Derartige Verfahren sind an sich bekannt und werden beispielsweise zum Herstellen von platten-, stangen- oder rohrförmigen Formkörpern verwendet.Such methods are known per se and are for example used for the production of plate, rod or tubular shaped bodies.
in Problem bei diesen Verfahren besteht grundsätzlich darin, daß das Gemisch bzw. die t-iasse nach den extrudieren eine ausreichende Menge an Wasser enthalten muß, um ein vollständiges Abbinden bzw. Aushärten des hydraulischen Zementes sicherzustellen. Weiterhin ist es bei Verfahren zum Extrudieren bzw. zum Strangpressen von Zementformkörpern erforderlich, daß das Gemisch trotz des zum Abbinden bzw. Aushärten des hydraulischen Zements erforderlichen Wasseranteils eine möglichst steife Masse bildet, damit sich die Formkörper nach dem Extrudieren und bis zum Abbinden bzw.The fundamental problem with these methods is that the Mixture or the t-cup after extruding a sufficient amount of water must contain to a complete setting or hardening of the hydraulic cement to ensure. It is also used for extrusion or extrusion processes of cement moldings, it is necessary that the mixture, in spite of the setting or Hardening of the hydraulic cement required water content as possible Stiff mass forms, so that the moldings after extrusion and up to Setting or
Aushärten des hydraulischen Zements in ihrer Formgebung nicht oder nur unwesentlich verundern.The hydraulic cement does not or does not harden in its shape change only insignificantly.
Bei bekannten Verfahren wird dieses Problem dadurch gelöst, daß dem Gemisch neben Extrudierungshilfsmittels und/oder Gleitmitteln, wie beispielsweise Tylose, Polyglykol und/oder Melment, Asbestfasern beigegeben werden, die aufgrund ihrer röhrchenförmigen Struktur Wasser adsorbieren und bei hohem Druck wieder abgeben. Hierdurch ist einerseits sichergestellt, daß das Gemisch nach dem Aushärten eine genügende Steifigkeit aufweist und anderes seits eine genügende enge an Wasser enthält, um ein vollständiges Abbinden bzw. Ausharten des hydraulischen Zementes sicherzustellen. tin Verfahren zum Strangpressen von formbeständigen, härtbaren Zementformkörpern unter Verwendung von Asbestfasern und Extrudierungs-Hilfsmitteln ist beispielsweise in der DE-AS 14 71 254 beschrieben.In known methods, this problem is solved in that the Mixture in addition to extrusion auxiliaries and / or lubricants, such as Tylose, polyglycol and / or melment, asbestos fibers are added due to Their tubular structure adsorb water and release it again at high pressure. This ensures on the one hand that the mixture after curing a has sufficient rigidity and, on the other hand, contains a sufficient amount of water, to ensure complete setting or hardening of the hydraulic cement. tin Process for the extrusion of dimensionally stable, hardenable cement moldings under Use of asbestos fibers and extrusion aids is described in DE-AS 14 71 254, for example.
Obwohl die bei bekannten Verfahren verwendeten Gemische aus Zement, aus dem Extrudierungshilfsmittel, aus Asbestfasern und Wasser zu guten Ergebnissen fuhren und nach dem Aushärten bzw. Abbinden des hydraulischen Zements Formkörper mit hoher Festigkeit liefern, besteht nach den neuesten Erkenntnissen ein erheblicher Nachteil der bekannten Verfahren bzw. der bei diesen Verfahren verwendeten Gemische in der gesundheitsschädlichen Wirkung der Asbestfasern. Gesundheitsschädliche Folgen sind dabei nicht nur bei der Verarbeitung der bekannten Gemische beim Herstellen von Zementformkörpern, sondern auch bei der späteren Verarbeitung bzw. Bearbeitung der ausgehärteten Zementformkörper zu erwarten.Although the mixtures of cement used in known processes, from the extrusion aid, from asbestos fibers and water for good results and after the hydraulic cement has hardened or set, molded bodies deliver with high strength, there is, according to the latest findings, a considerable Disadvantage of the known processes or the mixtures used in these processes in the harmful effects of asbestos fibers. Harmful consequences are not only involved in the processing of the known mixtures during manufacture of cement moldings, but also during later processing or processing of the hardened cement molding to be expected.
Der Erfindung liegt die Aufgabe zugrunde,-ein Verfahren zum Strangpressen von formbeständigen, härtbaren Zementformkörpern aufzuzeigen, bei welchem die Verwendung von gesundheitsschädlichen Asbestfasern nicht notwendig ist, und welches formbeständige, härtbare Zementformkörper liefert, die nach dem Extrudieren eine genügende Menge an Wasser enthalten, um ein vollstundiges Abbinden bzw. Aushärten des hydraulischen Zements sicherzustellen.The invention is based on the object of a method for extrusion of dimensionally stable, hardenable cement moldings, in which the use of harmful asbestos fibers is not necessary, and which dimensionally stable, Hardenable cement molded body provides, after extrusion, a sufficient amount contained in water in order to fully set or harden the hydraulic Ensure cement.
Zur Lötung dieser Aufgabe ist ein Verfahren der eingangs geschilderten Art erfindungsgernaß dadurch gekennzeichnet, daß das Gemisch neben organischen Fasern und/oder Glasfasern als Zuschlagsstoffe Kreide und/oder Kieselgur und/oder Talku/enthult.To accomplish this task, a method is that described at the outset Art erfindungsgernaß characterized in that the mixture in addition to organic fibers and / or glass fibers as additives chalk and / or kieselguhr and / or talc / enthult.
(blättchenförmiges Magnesiumsilikat) Mit dem erfindungsgemäßen Verfahren ist es möglich, formbeständige, härtbare Zementformkörper durch Extrudieren herzustellen, die gesundheits- -schädliche Asbestfasern nicht enthalten und die trotz der beim Extrudieren auftretenden erheblichen DrUcke eine ausreichende Menge an Wasser enthalten, damit ein vollständiges Abbinden bzw. Ausharten des Zements möglich ist. (flaky magnesium silicate) With the method according to the invention it is possible to produce dimensionally stable, hardenable cement moldings by extrusion, which do not contain harmful asbestos fibers and which in spite of the at Extruding significant pressures that occur contain a sufficient amount of water, so that a complete setting or hardening of the cement is possible.
Die mit dem erfindungsgemäßen Verfahren hergestellt n Zem3ntformkörper besitzen nach dem Aushärten bzw. Abbinden eine Festigkeit und vor allem auch eine Zugfestigkeit, die mit der Festigkeit von Asbestzementformkörpern vergleichbar sind. Versuche haben auch ergeben, da3 die Schlag- bzw.The molded cement bodies produced by the process according to the invention have a strength and, above all, a strength after hardening or setting Tensile strength comparable to the strength of asbestos cement moldings. Tests have also shown that the impact or
toßfestigkeit bei Formkörpern, die nach dem erfindungsgemäSen Verfahren hergestellt wurden, nach dem Abbinden bzw. Ausharten des hydraulischen Zementes vielfach sogar größer ist als die Schlag- bzw. Stoßfestigkeit vergleichbarer, nach bekannten Verfahren hergestellter Formkörper. high tensile strength in moldings produced by the process according to the invention after the hydraulic cement has set or hardened is often even greater than the impact or shock resistance comparable, according to known method of molded bodies produced.
