Verfahren zur Nachbehandlung von mit Formaldehyd imprägnierten Hölzern.
Bekanntlich behalten die durch Imprägnieren mit Formaldehyd wasserfest gemachten Holzgegenstände geringe Mengen des Formaldehydgases äusserst fest, die schwer zu entfernen sind, aber bewirken, dass bei nachheriger weiterer Verleimung des Holzes der Leim am Holz
EMI1.1
Oxydationsmittel zerstört. Das Verfahren kann z. B. in der Weise durchgeführt werden, dass man die weiter zu verleimenden Stellen des Holzes mit einer Lösung von Ammoniak und Wasserstoffsuperoxyd bestreicht, was dann zur Folge hat, dass nach Eintrocknen der Leim an diesen Stellen einwandfrei haftet.

Process for the post-treatment of wood impregnated with formaldehyde.
It is known that wooden objects made waterproof by impregnation with formaldehyde retain small amounts of the formaldehyde gas extremely firmly, which are difficult to remove, but have the effect that when the wood is subsequently further glued, the glue on the wood
EMI1.1
Oxidizing agent destroyed. The method can e.g. B. be carried out in such a way that the areas of the wood to be glued are coated with a solution of ammonia and hydrogen peroxide, which then has the consequence that after the glue has dried, the glue adheres perfectly to these areas.
