Description
Verfahren zur Herstellung von Sicherheitspapier Es ist bereits Gegenstand eines älteren Patents, bei der Herstellung von Sicherheitspapier dem Papierstoff im Holländer Ferromangancyanid und Eisenpulver zuzumischen.Process for the production of security paper It is already the subject of an older patent, in the manufacture of security paper, the paper stock to mix in ferromangancyanide and iron powder in the Dutch.
Außer der oben beschriebenen Sicherung des Papiers mit Ferromangancyanid und Eisenpulver, die mit verdünnten Säuren Blaufärbungen und zugleich mit Bsulfiten oder schwefliger Säure Gelbfärbungen entstehen lassen, müssenSicherheitspapieregegenChlo,reinw irkungen durch Manganverbindungen gesichert sein, deren Reaktionsprodukte jedoch mit den bekannten Mitteln reduzierender Natur leicht wieder entfernt werden können. Es ist deshalb notwendig, neben diesem wieder zu entfernenden Chlorreagenz einen nicht oder nur sehr schwer zu entfernenden Stoff ins Papier zu bringen, wozu sich vornehmlich Manganpulver eignet.In addition to securing the paper with ferromangancyanide as described above and iron powder, which turns blue with dilute acids and at the same time with sulfites or sulphurous acid cause yellow discolouration, security papers against chlo, pure white Effects of manganese compounds must be ensured, but their reaction products can easily be removed again with the known agents of a reducing nature. It is therefore necessary to have a chlorine reagent to be removed in addition to this to bring material into the paper that is difficult or impossible to remove, which is why Manganese powder is particularly suitable.
Durch den Zusatz von metallischem Mangan wird die braune Färbung, die bei Einwirkung von Chlor, insbesondere von alkalischen Chlorverbindungen, entsteht, bedeutend verstärkt und läßt sich somit auch kaum wieder entfernen, während bei Verwendung von Salzen oder Doppelsalzen des Mangans dieselbe durch reduzierende Mittel verhältnismäßig leicht wieder zu entfernen ist.By adding metallic manganese, the brown color, caused by the action of chlorine, especially alkaline chlorine compounds, significantly reinforced and can therefore hardly be removed again, while at Use of salts or double salts of manganese the same by reducing Medium is relatively easy to remove.
Gerade durch Zusatz einer Mischung von Eisen- und Manganpulver entstehen in Gegenwart von Ferromangancvaniden im Papier mittels verdünnter Säuren einerseits und mittels verdünnter alkalischer Chlorverbindungen andererseits Blau- und Braunfärbungen, die nicht wieder entfernbar sind, ohne den Charakter des Papiers deutlich zu zerstören.Created by adding a mixture of iron and manganese powder in the presence of ferro-manganese vanides in the paper by means of dilute acids on the one hand and on the other hand blue and brown colorations by means of dilute alkaline chlorine compounds, which cannot be removed again without clearly destroying the character of the paper.
Setzt man jedoch dieses Gemisch von Eisen-und Manganpulver in Gegenwart von Ferromangancyaniden denn Stoff im Holländer zu, so entstehen bei Zusatz von Aluminiumsulfat, Alaun, sauren Salzen oder Säuren unter Umständen Verfärbungen.However, if this mixture of iron and manganese powder is present of ferromangancyanides for substance in the Dutch, so arise with the addition of Aluminum sulfate, alum, acid salts or acids may cause discoloration.
Gegenstand vorliegender Erfindung bezweckt nun die Behebung dieser Schwierigkeiten bei .der Herstellung von Sicherheitspapieren unter Verwendung von Ferromangancyanid und Eisen in fein pulvriger Form und kennzeichnet sich dadurch, daß dem im Holländer mit Ferromangancyanid vermischten Stoff zwischen Stoffbütte und dem Sieb der Papiermaschine eine wäßrige Suspension von Eisen- und Manganpulver zugesetzt wird.The object of the present invention now aims to remedy this Difficulties in the production of security papers using Ferromangancyanide and iron in a finely powdered form and is characterized by that the fabric mixed with ferromangancyanide in the Dutchman between the cloth chest and the wire of the paper machine an aqueous suspension of iron and manganese powder is added.
Hierdurch werden die vorerwähnten Fabrikationsschwierigkeiten vermieden, da die Zeit, während der die verschiedenen Reaktionsmittel in reaktionsfähigem Zustand vorliegen, nicht ausreicht, um die unerwünschten Verfärbungen entstehen zu lassen.This avoids the manufacturing difficulties mentioned above, because the time during which the various reactants are in a reactive state present, is not sufficient to cause the undesired discoloration to occur.
Es ist zwar bereits bekannt, Stoffe, die im Holländer unerwünschte Reaktionen miteinander eingehen würden, möglichst lange voneinander fernzuhalten, indem man sie erst zwischen Stoffbütte und Sieb der Papierinaschine zusammenführt. Hierbei handelt es sich jedoch lediglich um die Herstellung von geleimtem, alkalische Füllstoffe enthaltendem Papier, nicht aber um Sicherheitspapier; das neben den Zusätzen wie FerromanganWnid und Eisenpulver noch Manganpulv er -; 7,ur besseren Sicherung gegen chlorhaltige Fälschungsflüssigkeiten enthält.Although it is already known substances that are undesirable in the Dutch Reactions would enter into each other, to keep away from each other as long as possible, by first placing them between the stock chest and the sieve of the paper machine brings together. However, this is only about the production of sized, alkaline Paper containing fillers, but not security paper; that next to the additives like ferromanganese wnide and iron powder nor manganese powder -; 7, ur better backup against counterfeit liquids containing chlorine.
Um das Sicherheitspapier nun auch gegen die letzte Gruppe von Radierwässern zu sichern, setzt man im Zusammenhang mit obengenannten Chemikalien dem Papierstoff in bekannter Weise noch Bleiverbindungen, wie Bleisulfat, Bleicarbonat oder Eisenbleicyanid, zu.To the security paper now also against the last group of erasers In connection with the above-mentioned chemicals, the paper stock is used to ensure that it is safe in a known manner lead compounds such as lead sulfate, lead carbonate or iron lead cyanide, to.
Ausführungsbeispiel i Dein Stqff im. Holländer wird gelbes Blutlaugensalz und Mängansulfat zugesetzt, nachdem beide Salze vorher in Wasser gelöst wurden; nachher wird Bleisulfat oder Bleicarbonat zugemischt, mit Leim und Alaun in der üblichen Weise geleimt und zwischen Stoffbütte und Papiermaschinensieb in gleichmäßigem Strom eine wäßrige Suspension von Eisen- und Manganpulver zugesetzt. Ausführungsbeispiel z Dein Stoff im Holländer wird bereits ausgefälltes Ferromangancyanid zugemischt, nachdem das Fällungsprodukt vorher gründlich ausgewaschen wurde, so daß weder ein Übcrschuß von gelbem Blutlaugensalz noch von Mangansulfat vorhanden war; nachher wird zier Stoff durch Bleisulfat aufgehellt, in der üblichen Weise geleimt und zwischen Stoffbütte und Papiermaschinensieb in gleichmäßigem Strom mit einer aus Eisen- und Manganpulver bestehenden wäßrigen Suspension versetzt.Embodiment i your Stqff im. Holländer becomes yellow blood liquor salt and manganese sulfate added after both salts were previously dissolved in water; afterwards lead sulphate or lead carbonate is mixed in, with glue and alum in the glued in the usual way and evenly between the pulp chest and the paper machine screen Stream an aqueous suspension of iron and manganese powder added. Embodiment z Your fabric in the Dutch is mixed with already precipitated ferro manganese anide, after the precipitation product has been thoroughly washed out beforehand, so that neither a There was still an excess of yellow blood-liquor salt of manganese sulphate; later decorative fabric is lightened by lead sulphate, glued in the usual way and between Chest and paper machine screen in a steady stream with one made of iron and Manganese powder added to existing aqueous suspension.
Ausführungsbeispiel 3 Wie im ersten und zweiten Ausführungsbeispiel werden dem Stoff im Holländer gelbes Blutlaugensalz und Mangansulfat und nachher gelbes Blutlaugensalz und Bleinitrat zugemischt, oder die beiden erstgenannten Salze werden wie im Ausführungsbeispiel 2 als Ferromangancyanid ebenso wie auch das Bleinitrat und gelbe Blutlaugensalz als Bleiferrocyanid gesondert ausgefällt, worauf mit einem Füllstoff, wie Blanc fixe, aufgehellt, in der üblichen Weise geleimt und zwischen Stoffbütte und Papiermaschinensieb in gleichmäßigem Strom eine wäßrige Suspension von Eisen- und Manganpuläer zugesetzt wird.Embodiment 3 As in the first and second embodiments yellow blood liquor salt and manganese sulphate are added to the substance in the Dutchman and afterwards yellow blood liquor salt and lead nitrate mixed in, or the first two salts mentioned are as in embodiment 2 as ferromangancyanide as well as lead nitrate and yellow blood liquor salt precipitated separately as lead ferrocyanide, whereupon with a Filler, like Blanc fixe, lightened, glued in the usual way and between Chest and paper machine screen in a steady stream an aqueous suspension of iron and manganese powder is added.
