Description
Verfahren zum Herstellen eines Bindemittels für preßbare Massen Die Erfindung betrifft ein Verfahren zum Herstellen eines Bindemittels, insbesondere für preßbare Massen und für Verwendungszwecke aller Art, z. B. zur Herstellung von Briketts, Platten, Formsteinen, Hohlkörpern und anderen Gegenständen aller Art.Process for preparing a binder for pressable masses Die The invention relates to a method for producing a binder, in particular for compressible masses and for all kinds of uses, e.g. B. for the production of Briquettes, plates, shaped stones, hollow bodies and other objects of all kinds.
Das Verfahren beruht auf der Beobachtung, daß sich eine stark eingedickte Paste mit gut bindenF den Eigenschaften bildet, wenn Sulfitablauge von 32" Be mit Calciumhydroxyd Ca(OH)2 versetzt wird.The method is based on the observation that a strongly thickened Paste with good binding properties forms when using sulphite waste liquor of 32 "Be Calcium hydroxide Ca (OH) 2 is added.
Es wurde schon früher versucht, Sulfitablauge als Bindemittel zu verwenden, doch waren diese Versuche unbefriedigend, weil die so hergestellten Erzeugnisse nicht genügend wetterfest waren. Das mit Ca(OH)2 hergestellte Bindemittel dagegen ist weitgehend wasserfest, ebenso die damit hergestellten Formkörper. Die Wasserfestigkeit steigt mit der Zugabe von ('a (OH ) " bis etwa 4o% auf 32°ige Sultitablauge gerechnet. In demselben Maße nimmt aber die Elastizität der fertigen Formkörper ab. Die Höhe der Zugabe von Ca (OH), hängt also von den gewünschten Eigenschaften des Endproduktes ab und schwankt daher zwischen 5 und 4o% auf die angewandte Sulfitablauge gerechnet.Attempts have been made earlier to use sulphite waste liquor as a binder, but these attempts were unsatisfactory because of the products made in this way were not sufficiently weatherproof. The binder made with Ca (OH) 2 on the other hand is largely waterproof, as are the moldings produced with it. The water resistance increases with the addition of ('a (OH) "up to about 40% to 32% sultitol waste liquor). However, the elasticity of the finished molded body decreases to the same extent. The height the addition of Ca (OH), therefore, depends on the desired properties of the end product and therefore fluctuates between 5 and 40% calculated on the sulphite waste liquor used.
Auf diese Weise gelingt ,es, aus Steinkohlen-oder Koksabfällen (Staub und/oder Grus) Briketts zu pressen, aus Sägemehl und/oder zerfasertem Holz Leichtbauplatten herzustellen usw. Bei der Herstellung derartiger Preßkörper geht man vorteilhafterweise so vor, daß der zu verpressende Stoff zuerst mit der Sulfitablauge gleichmäßig benetzt bzw. gemischt wird und dann durch Zugabe von Ca (O H ), das eigentliche Bindemittel hergestellt wird.In this way it succeeds, from hard coal or coke waste (dust and / or Grus) to press briquettes from sawdust and / or shredded wood lightweight panels manufacture, etc. In the manufacture of such compacts one goes advantageously so that the substance to be pressed is first evenly wetted with the sulphite waste liquor or is mixed and then by adding Ca (O H), the actual binder will be produced.
t. Beispiel Steinkohlenbriketts: In einer Mischmaschine vermischt man too Gewichtsteile Feinkohle (Staub und/oder Grus) mit toGew:ichtsteilen Sulfitablauge 32° B6 und -gibt -dann- 3 Gewichtsteile Ca (O H).. unter weiterem Mischen zu.t. Example of hard coal briquettes: mixed in a mixer man too parts by weight of fine coal (dust and / or grit) with to weight: ichtsteile sulphite waste liquor 32 ° B6 and then add 3 parts by weight of Ca (O H) .. with further mixing.
Die Masse wird durch den Ca(OH)2-Zusatz trockener und plastisch. Dann bringt man die Masse durch Pressen in .die gewünschte Form, worauf man die Preßkörper trocknet.The addition of Ca (OH) 2 makes the mass drier and more plastic. then you bring the mass by pressing in .die desired shape, whereupon the pressed body dries.
21 Beispiel Leichtbauplatten: Für Leichtbauplatten aus Sägemehl, zerfasertem Holz und/oder anderen Holzabfällen ist folgender Ansatz geeignet: ioo Gewichtsteile Sägemehl oder Holzfaser, ioo Gewichtsteile Sulfitablauge 32'B6, 25 Gewichtsteile Ca(OH)2 werden wie oben angegeben vermischt, gepreßt und getrocknet.21 Example of lightweight panels: For lightweight panels made of sawdust, frayed The following approach is suitable for wood and / or other wood waste: 100 parts by weight Sawdust or wood fiber, 100 parts by weight of sulphite waste liquor 32'B6, 25 parts by weight Ca (OH) 2 are mixed, pressed and dried as indicated above.
Statt Kohlen-, Koks- oder Holzabfällen kann auch jedes andere hierzu geeignete Material, wie Torf, Stroh, Holzwolle, Laub, Tannenzapfen, Bimsstein usw., verwendet werden. Auch kann das Bindemittel zur Herstellung von Sandgießformen und -kernen verwendet werden.Instead of coal, coke or wood waste, any other can also do this suitable material, such as peat, straw, wood wool, leaves, pine cones, pumice stone, etc., be used. The binder can also be used for the production of sand casting molds and cores are used.
In der Praxis wird man nicht reines Ca(OH)2 verwenden, sondern gelöschten Weißkalk oder Schwarzkalk. 'Man kann sogar das lästige Abfallprodukt, den Carbidschlamm, verwenden. Die anzuwendenden Gewichtsteile richten sich dann nach dem wahren Gehalt des angewandten Stoffes an Ca (0H)2 und müssen aus dessen wahrem Gehalt an diesem errechnet werden.In practice, you will not use pure Ca (OH) 2, but quenched Ca (OH) 2 White lime or black lime. 'You can even get rid of the annoying waste product, carbide sludge, use. The parts by weight to be used then depend on the true content of the applied substance of Ca (0H) 2 and must be based on its true content of this can be calculated.
Das Bindemittel kann auch zur Herstellung von Hohlkörpern aller Art, z. B. von Dosen, Schachteln usw., aus anderem Material und zu anderen Gegenständen verwendet werden.The binder can also be used for the production of all types of hollow bodies, z. B. from cans, boxes, etc., made of other material and other objects be used.
Das Bindemittel eignet sich für Kalt- und Warmpressung.The binder is suitable for cold and hot pressing.
