PATENTSCHRIFTPATENT LETTERING
(Grfsch. Middlesex, England).(Middlesex, England).
Patentirt im Deutschen Reiche vom 18. Mai 1894 ab.Patented in the German Empire on May 18, 1894.
Die Eigenschaft des Kupferoxydammoniaks, Cellulose zu lösen, wird bekanntlich vielfach zur Behandlung von Papier und Geweben, z. B. zum Zweck der Wasserdichtmachung angewendet (s. g. Willesden-Verfahren).The property of copper oxide ammonia to dissolve cellulose is known to be many for the treatment of paper and fabrics, e.g. B. used for the purpose of waterproofing (see g. Willesden procedure).
Ich habe nun gefunden, dafs das Kupferoxydammoniak für die vorliegenden Zwecke dadurch geeigneter wird, dafs man es mit einem löslichen Chromat (Natrium-, Kaliumoder Ammoniumchromat bezw. -bichromat) versetzt, indem diese Composition dem Product klarere Tönung und gröfsere Dauerhaftigkeit verleiht.I have now found that copper oxide ammonia can be used for the present purposes it becomes more suitable by treating it with a soluble chromate (sodium, potassium or Ammonium chromate respectively. -bichromat) by adding this composition to the Product gives a clearer tint and greater durability.
In manchen Fällen ist es zweckmäfsig, das behandelte Papier oder Gewebe nach dem Trocknen zur Auswaschung vorhandener löslicher Stoffe durch heifses Wasser zu ziehen. Soll auch gefärbt werden, so kann man die Farbstoffe gleich.in dem. Waschwasser lösen.In some cases it is useful to clean the treated paper or fabric after Drying to wash out existing soluble substances through hot water. If there is also to be colored, the dyes can be used in the same way. Dissolve wash water.
Ein sehr wirksames Bad läfst sich billig ohne Gegenwart von Luft zur Oxydation des Kupfers bereiten, indem man in Verbindung mit Kupfer und Ammoniakflüssigkeit Ammoniumchromat benutzt oder eine andere Chromverbindung' welche in Berührung mit freiem Ammoniak Ammoniumchromat bildet, vorzugsweise Kaliumoder Nätriumbichromat. Sehr zweckmäfsig verfährt man in folgender Weise:A very effective bath can be done cheaply without the presence of air to oxidize the copper Prepare by putting ammonium chromate in conjunction with copper and ammonia liquid used or another chromium compound which comes into contact with free ammonia Ammonium chromate forms, preferably potassium or sodium dichromate. Proceeds very appropriately one in the following way:
Reine Kupferspäne (am besten Kupferblechspäne) vermischt man in einem mit Rührwerk versehenen Gefäfs (rotirende Trommel) mit dem dreifachen Gewicht Kaliumbichromat, läfst dann Ammoniakfiüssigkeit von 8 bis 15 pCt. hinzulaufen und unter Rühren (oder Rotiren der Trommel) etwa 2 bis 12 Stunden (je nach dem Grade des Rührens, der Stärke der Ammoniakflüssigkeit und der Bichromatmenge) einwirken. Dann läfst man den Inhalt in ein Setzgefäfs zum Absetzen des ausgeschiedenen Chromoxydhydrates fliefsen. Die vom Niederschlag getrennte klare Flüssigkeit ist fertig zum Gebrauch. Der Niederschlag wird mit schwacherAmmoniakflüssigkeit, schliefslich mit Wasser gewaschen, abfiltrirt, geprefst und getrocknet. Er kann als Farbe oder zu anderen Zwecken benutzt werden. Die Waschflüssigkeit wird zweckmäfsig bei der Bereitung des Bades benutzt, indem man mit ihr starke Ammoniakflüssigkeit auf den Verbrauchsgrad verdünnt.Pure copper shavings (preferably sheet copper shavings) are mixed in a mixer with a mixer provided vessel (rotating drum) with three times the weight of potassium dichromate, then drains ammonia liquid from 8 to 15 pCt. to run in and stir (or rotating the drum) about 2 to 12 hours (depending on the degree of stirring, the strength of the ammonia liquid and the amount of bichromate). Then you run the contents flow into a sedimentation vessel to settle the precipitated chromium oxide hydrate. The clear liquid separated from the precipitate is ready for use. The precipitation gets with weak ammonia fluid, eventually washed with water, filtered off, pressed and dried. It can be as color or too used for other purposes. The washing liquid is expedient in the preparation of the bath by using strong ammonia liquid on the consumption level diluted.
Die Menge des löslichen Chromats, welches in dem wie beschrieben bereiteten Bad enthalten ist, wechselt mit dem ursprünglichen Verhältnifs zwischen Kupfer und Chromat; sie besteht aus dem Rest, welcher nicht zur Oxydation des Kupfers aufgebraucht worden ist, welche unter Reduction des Chromates zu Chromsesquioxyd stattfindet.The amount of soluble chromate contained in the bath prepared as described is, alternates with the original ratio between copper and chromate; she consists from the remainder which has not been used up to oxidize the copper, what takes place with reduction of the chromate to chromium sesquioxide.
Zur Behandlung mit dem Bad wird das Papier etc., wie beim Willesden-Verfahren in dasselbe eingetaucht, dann durch Äusprefswalzen hindurchgezogen und getrocknet. Wird noch Auswaschen nöthig, so nimmt man dies, wie bereits angegeben, mit heifsem Wasser vor. Nach dem Trocknen zeigt dann das Product eine mehr oder weniger grüne Färbung. SollFor treatment with the bath, the paper etc. is used, as in the Willesden method immersed in the same, then pulled through finishing rollers and dried. Will If washing is still necessary, this is done, as already stated, with hot water. After drying, the product then shows a more or less green color. Intended to
diese durch eine andere ersetzt werden, so wendet man statt des Wassers ein Färbebad an. Anstatt das Papier, Gewebe etc. mit einem Bad aus Kupferoxydammoniak und löslichem Chromat zu behandeln, ist es für gewisse Fälle zweckmäfsiger, das Papier etc. wie im Willesd e η - Verfahren mit Kupferoxydammoniak zu behandeln und es vorher oder nachher durch eine heifse oder kochende Chromatlösung zu ziehen.If this is replaced by another, a dye bath is used instead of water. Instead of the paper, tissue etc. with a bath of copper oxide ammonia and soluble To treat chromate, it is more useful in certain cases to treat the paper, etc. as in Willesd e η - method of treating with cuprous ammonia and doing it before or after to draw a hot or boiling chromate solution.
