Verfahren zur Reinigung bzw. Auffrischung von Gegenständen aus Zelluloid,
Azetylzellulosemassen und dgl.
Es Ist bekannt, dass Zelluloidgegenstände beim Gebrauche bald unansehnlich werden und dass dies auch beim Nichtgebranche derselben, schon durch einfache längere Lagerung eintreten kann. Durch das den Erfindungsgegenstand bildende Verfahren gelingt es nun in technisch einfacher und ökonomisch vorteilhafter Weise, Zelluloidgegenstände leicht zu reinigen und ihnen wieder das völlige Aussehen neuer Ware zu verleihen. Auch für Gegenstände aus Azetylzellulosemassen und anderen Zelluloidersatzmitteln lässt sich dieses Verfahren anwenden.
Das Verfahren besteht im Wesen darin, dass man die Zelluloidgegenstände kurze Zeit bei gewöhnlicher Temperatur in englische Schwefelsäure taucht, sie hierauf mit Wasser wäscht, trocknet kurze Zeit sodann in starkem Alkohol liegen lässt und schliesslich dieselben mit Kampferkollodium überstreicht. Das Einbringen in Alkohol kann eventuell in manchen Fällen weggolassen werden.
Bei der Ausführung des Verfahrens geht man zweck- mässig folgendermassen vor : Die Gegenstände werden unmittelbar, ohne jede vorbereitende Behandlung, bei Zimmertemperatur (etwa 200 C) 1/4 Minute lang in englische Schwefelsäure getaucht, so dass deren Oberfläche allseitig von der Säure benetzt wird, dann aus

trocknen ein zweites oder öfteres Mal zu wiederholen ist, bis die Ware die Glätte und den (jlanz der ganz neuen wieder besitzt.
FUr noch rascheres Arbeiten kann man wohl auch die Zwischenbehandlung mit Alkohol weglassen und die nach dem Abspülen mit Wasser von der anhaftenden Schwefelsäure befreite Ware nach oberflächhchem Abtrocknen, was schliesslich durch Abreiben mit trockenen Tüchern zu Ende zu fuhren ist, durch Überstreichen mit Kampferkollodiuu) glänzen und glätten.
Eine Nachbehandlung mit Kampferkollödium, ist unter allen Umständen notwendig, da die mit H2SO4 dekapierten Gegenstände auch nach sorgfiiltigstem Waschen mit Wasser, N 113 oder Na2 CO3 usw. matt werden und dann um so rascher Schmutzteile aufnehmen und vergilben.
Durch das beschriebene Verfahren werden auch eventuelle Krankheitskeime mit Sicherheit vernichtet.

Process for cleaning or freshening up celluloid objects,
Acetyl cellulose masses and the like.
It is known that celluloid objects soon become unsightly when they are in use and that this can occur even if they are not used, simply by storing them for a long time. The process forming the subject of the invention now makes it possible in a technically simple and economically advantageous manner to easily clean celluloid objects and to give them the full appearance of new goods. This method can also be used for objects made from acetyl cellulose compounds and other celluloid substitutes.
The essence of the process is that the celluloid objects are immersed in English sulfuric acid for a short time at normal temperature, then washed with water, dried for a short time, then left to lie in strong alcohol and finally coated with camphor collodion. The incorporation in alcohol may possibly be omitted in some cases.
The procedure for carrying out the process is as follows: The objects are immediately immersed in English sulfuric acid for 1/4 minute at room temperature (approx. 200 C), without any preparatory treatment, so that their surface is wetted by the acid on all sides , then off
EMI1.1
EMI1.2
drying has to be repeated a second or more time until the goods have the smoothness and gloss of the completely new one again.
For even faster work one can probably omit the intermediate treatment with alcohol and shine and shine the product, freed of the adhering sulfuric acid after rinsing with water, after drying on the surface, which is finally to be done by rubbing with dry cloths, by painting over it with camphor colloid smooth.
Subsequent treatment with camphor colodium is necessary under all circumstances, since the objects pickled with H2SO4 become matt even after careful washing with water, N 113 or Na2 CO3 etc. and then absorb dirt particles all the more quickly and turn yellow.
Possible germs are also destroyed with certainty by the method described.
