Description
Verfahren zum Bleichen von Holz. Gegenstand des vorliegenden Patentes, ist ein Verfahren zum Bleichen von Holz, das dadurch gekennzeichnet ist, dass man Idas Holz mit einer sauren Waasserstoffsuperoxydlösung behandelt.
Vorzugsweise erfolgt die Behandlung nachdem das Holz albgelaugt worden ist. Man geht beispielsweise so vor, dass man auf die abgelaugte, von Farb- und Lack- rückständen befreite Holzfläche mit dem Pinsel eine 15%ige Wasserstoffsuperoxyd- lösung, die ä % technische Schwefelsäure enthält, aufstreicht. Nachdem die Bleichung Mattgefunden hat,
wird mit Wasser abge- waschen. Mit dem vorliegenden Verfahren ist es möglich, durch grau ge wordenem oder beim, Ablaugen nachgedun keltem Holz Beinen Naturton wieder zu ver leihen.
Process for bleaching wood. The subject of the present patent is a process for bleaching wood, which is characterized in that Ida's wood is treated with an acidic hydrogen peroxide solution.
The treatment is preferably carried out after the wood has been leached. One proceeds, for example, that a 15% hydrogen peroxide solution, which contains 1% technical sulfuric acid, is spread with a brush onto the leached wood surface, which has been freed from paint and varnish residues. After the bleach finds matte,
is washed off with water. With the present method it is possible to give legs a natural tone again by turning gray or by removing lye after darkening the legs.
