Description

Verfahren zur Herstellung eines Füllmittels für tierischen Leim aus zerkleinertem Holz und mineralischen Stoffen Es sind Leimzusatzmittel, die zur Verdickung des Leimes dienen, um ein Durchschlagen des Leimes durch dünne oder poröse Furniere zu verhindern, bekannt. So wurde dem Leim schon Schlämmkreide zugesetzt, die aber den Leim so hart macht, da,ß bei der nachherigen Verarbeitung der geleimten Gegenstände die Werkzeuge stumpf werden.Process for the production of a filler for animal glue Crushed wood and mineral substances There are glue additives that contribute to thickening of the glue are used to allow the glue to penetrate through thin or porous veneers known to prevent. So chalk has already been added to the glue, but that makes the glue so hard that it is during the subsequent processing of the glued objects the tools become dull.

Es ist ferner bekannt, dem Leim feinen ungebrannten Gips oder Kalk nebst etwas Ocker als Farbstoff beizumengen. Auch diese Zusatzmittel härten den Leim zu sehr und erschweren das weitere Bearbeiten der geleimten Teile. Alle diese schweren Zusatzmittel setzen sich außerdem in den Leimgeschirren und den Leimauftragmaschinen zu Boden.It is also known to glue fine unfired plaster of paris or lime add some ocher as a coloring agent. These additives also harden the Glue too much and make further processing of the glued parts difficult. All these Heavy additives also settle in the glue pots and glue application machines to the ground.

Es ist auch schon versucht worden, Sägemehl als Leimzusatz zu verwenden. Dieses Material hat aber den Nachteil, daß es viel zu grob ist, um die feinen Poren im Holz auszufüllen. Alle diese Nachteile fallen durch das Verfahren zur Herstellung eines Füllmittels für tierischen Leim aus zerkleinertem Holz und mineralischen Stoffen gemäß der vorliegenden Erfindung fort.Attempts have also been made to use sawdust as an additive to glue. However, this material has the disadvantage that it is much too coarse to form the fine pores to be filled in in the wood. All of these drawbacks are eliminated by the method of manufacture a filler for animal glue made from crushed wood and mineral substances in accordance with the present invention.

Dasselbe kennzeichnet sich dadurch, daß man das Holz in Form von Holzschliff oder Holzmehl mit gepulverten, mineralischen Stoffen unter Druck, z. B. in einem Walzenstuhl. miteinander innig vermengt.The same is characterized by the fact that the wood is ground in the form of wood pulp or wood flour with powdered, mineral substances under pressure, e.g. B. in one Roller mill. intimately mixed with each other.

Das Gemisch aus Holzmehl und Mineralstoffpulver wird als Zusatzmittel dem flüssig gemachten Leim beigemengt. Das Vermischen von Leim und Zusatz erfolgt leicht und gleichmäßig. Der Zusatz bleibt im Leim in der Schwebe und setzt sich nicht ab. Das Holzmehl muß aber mit dem mineralischen Mehl trocken und unter Druck gemischt werden, z. B. unter Verwendung von Stahlwalzen. Dabei werden die feinen Mineralkörnchen in die weichen Holzmehlteilchen :eingepreßt, wodurch neue Körper mit etwa dem gleichen spezifischen Gewicht wie die Leimbrühe entstehen. Das Holzmehl wird in verschiedenen Mahlprozessen aus Sägespänen hergestellt. Nach jedem Mahlprozeß werden die harten Splitter der Jahresringe ausgeschieden, so daß zuletzt nur noch die weichsten Teile des Holzes übrigbleiben.The mixture of wood flour and mineral powder is used as an additive added to the liquefied glue. The glue and additive are mixed together light and even. The additive remains suspended in the glue and sits down not off. The wood flour must, however, with the mineral flour, dry and under pressure be mixed, e.g. B. using steel rollers. Thereby the fine Mineral granules in the soft wood flour particles: pressed in, creating new bodies with about the same specific weight as the glue broth. The wood flour is made from sawdust in various grinding processes. After each grinding process the hard splinters of the annual rings are excreted, so that in the end only the softest parts of the wood are left over.

Zu 5o kg streichfertigem Leim setzt man beispielsweise 5o kg des Füllmittels hinzu. Das Füllmittel kann beispielsweise folgende Zusammensetzungen haben: i. go % Gips, roh gemahlen, und io % Holzmehl, puderfein geschliffen; a. 45 % Gips, roh gemahlen, 45 % Kreide, io % Holzmehl, puderfein geschliffen.For example, 50 kg of the filler is added to 50 kg of ready-to-use glue added. The filler can, for example, have the following compositions: i. go % Plaster of paris, ground raw, and 10% wood flour, ground powder-fine; a. 45% plaster, raw ground, 45% chalk, 10% wood flour, powder-fine sanded.

Ein Durchschlagen des mit diesem Zusatzmittel vermengten Leimes ist ausgeschlossen. Es hat sich auch gezeigt, daß eine mit dem Zusatz gemäß der Erfindung vorgenommene Verleimung viel schneller abbindet. Ein weiterer Vorteil dieses Zusatzmittels besteht darin, daß der Leim erheblich gestreckt werden kann.Striking through of the glue mixed with this additive is locked out. It has also been shown that one with the additive according to the invention gluing carried out sets much faster. Another advantage of this additive is that the glue can be stretched considerably.
