KLASSE 54: Papiererzeugnisse.CLASS 54: Paper products.
Vorliegend beschriebenes Verfahren zur Herstellung von Sicherheitspapier besteht in der besonderen Bereitung der Papiermasse, welcher man verschiedene Ingredienzen wie harzsaure, metallische Salze beimischt, z. B. harzsaures Eisenoxydul mit einem Gemenge einer harzigen Verbindung von Ferrocyanblei oder Ferrocyanzinnoxyd und einer harzigen Verbindung von Ferrocyanmanganoxyd.The presently described method for producing security paper consists in the special preparation of the paper pulp, to which various ingredients such as resinous acid, metallic salts admixed, e.g. B. resinous iron oxide with a mixture of a resinous one Connection of ferrocyan lead or ferrocyanine oxide and a resinous compound of Ferrocyan Manganese Oxide.
Um besonders empfindliche Sicherheitspapiere herzustellen, wird der oben genannten Mischung noch ein Gemenge von harzsaurem Molybdänsalz oder harzsaurem Cadmiumoxyd zugesetzt, dem man harziges Schwefelzink beimischt. Das Ganze wird mit etwas Borax versetzt und mit der Papiermasse weiter verarbeitet.In order to produce particularly sensitive security papers, the mixture mentioned above is used another mixture of resinous molybdenum salt or resinous cadmium oxide added, which is mixed with resinous zinc sulphide. The whole thing is mixed with a little borax and with the paper pulp further processed.
Auf gewöhnlichem Wege würde ein Zusatz von Eisensalzen mit Ferrocyankali die Papiermasse blau färben, besonders wenn man zum Schlufs der Fabrikation die Harzseife mit Alaun zersetzt, wie es beim Leimen der Fall ist. Diese Färbung wird aber durch die Isolireigenschaften der harzigen metallischen Verbindungen verhindert. In the usual way, an addition of iron salts with ferrocyanic potassium would make the paper pulp Color blue, especially if you add the resin soap with alum at the end of the manufacturing process decomposes, as is the case with gluing. This coloring is due to the insulating properties the resinous metallic compounds prevented.
Um Schwefelzink direct auf der Faser zu fixiren, wird ein Theil der angewendeten Papiermasse mit schwefelsaurem Zink angerührt und dann ohne jeden Ueberschufs mit Harzseife und Schwefelnatrium zersetzt.In order to fix zinc sulphide directly on the fiber, part of the paper pulp used is used mixed with zinc sulphate and then decomposed without any excess with resin soap and sodium sulphide.
Alle diese harzigen Verbindungen haben den Hauptzweck, die verschiedenen metallischen Niederschläge in alkalischem Zustand auf der Faser leicht haften zu machen; ohne dies würden die nicht harzigen einzelnen Niederschläge im Lauf der Fabrikation gröfstentheils verschwinden.All of these resinous compounds have the main purpose of being the various metallic ones To make precipitates in an alkaline state easily adhere to the fiber; without this the non-resinous individual precipitates would for the most part in the course of manufacture disappear.
Die verschiedenen Salze werden in folgendem Verhältnifs bei Herstellung von 50 kg Papier verwendet: Zu den hierzu erforderlichen 150 kg Papiermasse, welche wie gewöhnlich gebleicht und gereinigt wird, bringt man während des Betriebes der Papiermaschine noch 100 bis 150 g Eisensulfat, das in etwas Wasser gelöst und mit einem kleinen Ueberschufs von Harzseife versetzt ist, ferner ein Gemenge von 600 bis 700 g Borax, 900 bis 1 000 g Ferrocyankalium in 20 1 Wasser, und so viel Kolophoniumseife, dafs sich 1 kg Harz in der genannten Seifenlösung befindet. Nach gehörigem Umrühren und Vermischen der Papiermasse mit dieser harzigen Verbindung setzt man noch eine Lösung von 400 bis 500 g Bleiacetat oder Zinnchlorür in 10 1 Wasser zu. Dann wird wieder umgerührt und nochmals folgende Mischung zugegeben: a) 10 1 Wasser, 800 bis 1 000 g Ferrocyankalium, b) ι 000 bis ι 200 g Mangansulfat oder -Chlorür.The different salts are used in the following proportions in the production of 50 kg of paper: In addition to the 150 kg of paper pulp required for this, which is bleached as usual and is cleaned, 100 to 150 g are added while the paper machine is in operation Iron sulfate, which is dissolved in a little water and with a small excess of resin soap is added, furthermore a mixture of 600 to 700 g of borax, 900 to 1,000 g of potassium ferrocyanine in 20 liters of water, and so much rosin soap that there is 1 kg of resin in the above-mentioned soap solution is located. After proper stirring and mixing of the paper pulp with this resinous one A solution of 400 to 500 g of lead acetate or tin chloride is added to the compound in 10 l of water. Then stir again and add the following mixture again: a) 10 1 water, 800 to 1,000 g of potassium ferrocyanide, b) ι 000 to ι 200 g of manganese sulfate or chlorine.
Der gebildete Niederschlag von Ferrocyanmangan wird alsdann mit einer Lösung von 60 1 Harzseife (3 kg Kolophonium enthaltend) versetzt.The precipitate formed of ferrocyanized manganese is then treated with a solution of 60 1 resin soap (containing 3 kg rosin) are added.
Wenn nun ein Molybdän- oder Cadmiumsalz gebraucht werden soll, so nimmt man im ersteren Falle etwa 400 g molybdänsaures Ammoniak, das man mit der äquivalenten Menge Bleiacetat zersetzt und der obigen Masse beimischt. If a molybdenum or cadmium salt is to be used, then one takes the in the first case about 400 g of ammonia molybdenum, which is mixed with the equivalent amount Lead acetate decomposes and mixed with the above mass.
Cadmiumsalz dagegen wird der Manganlösung beigemischt, und zwar im Verhältnifs von 400 bis 500 g.Cadmium salt, on the other hand, is added to the manganese solution, in proportion from 400 to 500 g.
In beiden Fällen wird harziges Schwefelzink, das, wie oben erklärt, auf der Faser fixirt ist, beigemengt, so dafs unter jeder sauren Reaction im Falle einer Fälschung sich ein echtes braun oder dunkel gefärbtes Molybdän- oder Cadmiumsulfid auf dem Papier bildet.In both cases, resinous zinc sulphide, which, as explained above, is fixed on the fiber, added, so that under every acidic reaction, in the case of a forgery, a real brown appears or forms dark colored molybdenum or cadmium sulfide on the paper.
Zum Schlufs zersetzt man, um das Papier fertig zu machen, die überschüssige Harzseife, die sich mit oben erwähntem Metallsalze nicht gebunden hat, mit 3 bis 4 kg Alaun. Nur wenn die Masse zu sauer reagirt, neutralisirt man mit etwa 500 g Borax oder phosphorsaurem Natron. Dieser Zusatz hat den Zweck, überschüssigen Alaun in Form eines neutralen Niederschlages zu fixiren.Finally, to finish the paper, you decompose the excess resin soap, which has not bonded with the metal salts mentioned above, with 3 to 4 kg of alum. Just if the mass reacts too acidic, it is neutralized with about 500 g of borax or phosphoric acid Baking soda. The purpose of this addition is to make excess alum in the form of a neutral To fix the precipitation.
