Description

Bindemittel für Furniere. Die in der Möbelindustrie verwendeten Furniere zeigen den Übelstand, daß,, j e poröser sie sind, um so leichter der zum Befestigen der Furniere auf ihre Grundlage verwendete Leim durch die Furniere hindurchdringt.Binders for veneers. The veneers used in the furniture industry show the disadvantage that the more porous they are, the easier it is to fix them The glue used on their base of veneers penetrates through the veneers.

Zur Verhinderung des Übelstandes hat man dem Leim Schlämmkreide beigemengt. Der Zusatz mußte aber, um den Zweck zu erreichen, beträchtlich sin, hierdurch leidet aber die Bindekraft des- Leimes.To prevent the problem, chalk has been added to the glue. The addition, however, had to be considerable in order to achieve the purpose; it suffers as a result but the cohesiveness of the glue.

Nach der vorliegenden Erfindung wird dem Lederleim Lenzin und Ocker zugesetzt. Lenzin besteht nach der Analyse von Dr. F r e s e n .i u s in Frankfurt a. M. aus: 21,36 Prozent Wasser, 28,¢3 » Calciumsulfat, 0,21 » Tonerde. Es weicht also von dem in der Papierfabrikation benutzten gleichnamigen Kunstprodukt, der lediglich aus gebranntem feingemahlenen Gips besteht, in der Zusammensetzung ab. Es kommt in der Natur vor und wird z. B. in Kornberg bei Bad Sooden gefunden. Ocker wird der Masse beigemischt, um eine dem Furnier ähnliche Färbung zu erhalten. Beispiel. io kg Lenzin, 15 g Ocker und 31 Wasser werden mit 5 kg in Wasser 14 Stunden lang eingeweichtem Lederleim vermischt.According to the present invention, the leather glue is lenzine and ocher added. According to Dr. F r e s e n .i u s in Frankfurt a. M. from: 21.36 percent water, 28.3 "calcium sulfate, 0.21" clay. It gives way So from the art product of the same name used in paper manufacture, the consists only of burnt, finely ground plaster of paris, in the composition. It occurs in nature and is z. B. found in Kornberg near Bad Sooden. ocher is added to the mass in order to obtain a color similar to the veneer. Example. 10 kg of lenzine, 15 g of ocher and 31 g of water are mixed with 5 kg in water for 14 hours mixed with soaked leather glue.

Das vorliegende Bindemittel ermöglicht, die Anwendung von heißen Preßstücken zum Anpressen des Furniers auf seiner Grundlage, ohne daß der Leim durchschlägt; das sonst übliche Einfetten der Furnieroberfiächen erübrigt sich also. Ferner ist der Klebstoff sandfrei, die bei der späteren Bearbeitung der Hölzer benutzten Werkzeuge werden daher nicht angegriffen..The present binder enables the use of hot compacts for pressing the veneer on its base without the glue penetrating; the otherwise usual greasing of the veneer surfaces is not necessary. Furthermore is the glue is sand-free, the tools used for later processing the wood are therefore not attacked.

Die Abbindung der furnierten Fläche erfolgt schon in 3 bis 3'-j2 Stunden statt in ¢ bis 5 Stunden wie sonst.The veneered surface is set in 3 to 3 1/2 hours instead of ¢ up to 5 hours as usual.
