Description

Verfahren zur Herstellung haltbarer chemischer Echtvorbeizen Bekanntlich werden die besten und dauerhaftesten Beizungen bei Möbeln dadurch erzielt, daß man mit einer Vorbeize, die aus Gerbsäuren oder verwandten Stoffen besteht, das Holz vorbeizt und dann mit solchen meist Schwermetallsalzauflösungen nachheizt, die mit den Gerbsäuren des Holzes oder den zugeführten Säuren unlösliche, lichtbeständige und echtfärbende Verbindungen ergeben.Process for producing durable chemical pre-pickling is known the best and most durable stains on furniture are achieved by with a pre-stain consisting of tannic acids or related substances, the wood pickled and then reheated with such mostly heavy metal salt solutions that with The tannic acids of the wood or the added acids are insoluble and lightfast and give fast coloring compounds.

Ein sehr großer Übelstand der z. B. mit Pyrogallussäure bereiteten Vorbeizen ist der, daß sie infolge Sauerstoffaufnahme und sonstiger Umsetzungen nicht lange in flüssiger Lösung gehalten werden können und sich dabei stark verfärben.A very big disadvantage of z. B. prepared with pyrogallic acid Pre-pickling is that it as a result of oxygen uptake and other reactions cannot be kept in liquid solution for long and become very discolored.

Es wurde nun gefunden, daß man durch Zusatz von Alkalisulfit und etwas Schwefelsäure die Lösungen unbegrenzt lange haltbar machen kann und daß sie dann auch ihre helle Farbe behalten. An Stelle von Alkalisulfit und Schwefelsäure kann auch, namentlich bei Abgabe in Pulverform, pulverförmiges Alkalidisulfit verwendet werden.It has now been found that by adding alkali metal sulfite and something Sulfuric acid can make the solutions durable indefinitely and that they then also keep their light color. Instead of alkali sulfite and sulfuric acid can also, especially when supplied in powder form, powdered alkali metal disulphite is used will.

Beispiel zooo Teile Wasser, 30 » Pyrogallol(oderBrenzcatechinoder Resorcin), q0 » Natriumsulfit, 3 » Schwefelsäure.Example zooo parts water, 30 »pyrogallol (or catechol or Resorcinol), q0 »sodium sulfite, 3» sulfuric acid.

Diese Lösung ist unbegrenzt lange haltbar, bleibt farblos und färbt beim Auftrag auch das Holz nicht.This solution has an unlimited shelf life, remains colorless and stains not even the wood when it is applied.
