Description

Verfahren zur Herstellung von in der Kälte flüssig bleibendem Knochen- oder Lederleim. Der nach dem Hauptpatent hergestellte, in der Kälte flüssigbleibende Tierleim läßt sich nach dem Erstarren bzw. Trocknen erneut mit Wasser lösen. Dieser Übelstand wird behoben durch einen Zusatz von Formaldehyd und Alaun, welcher Zusatz den einmal getrockneten Leim gegen erneutes Auflösen im Wasser schützt. Eine gewöhnliche Leimlösung wird bereits. durch Zusatz von einigen Tropfen Formalin koaguliert. Dies ist jedoch nicht der Fall bei einem Leim mit einem Zusatz von Ameisensäure oder einem Salz derselben; vielmehr bleibt ein solcher Leim mehrere Tage gebrauchsfähig. -Nach dem Verfahren werden q.oo Teilen einer Leimlösung mit Ameisensäuregehalt annähernd 8 Teile Formaldehyd und 8 Teile Alaunlösung zugesetzt.Process for the production of bone that remains liquid in the cold or leather glue. The one manufactured according to the main patent, which remains liquid in the cold Animal glue can be dissolved again with water after it has solidified or dried. This The problem is remedied by adding formaldehyde and alum, which additive Protects the once dried glue against dissolving again in the water. An ordinary one Glue solution will already be. coagulated by adding a few drops of formalin. this however, this is not the case with a glue with an addition of formic acid or a salt thereof; on the contrary, such a glue remains usable for several days. -After the procedure, q.oo parts of a glue solution with formic acid content approximate 8 parts of formaldehyde and 8 parts of alum solution were added.
