Description
Patentiert im Deutschen Reiche vom 6. Februar 1915 ab.Patented in the German Empire on February 6, 1915.
Um Altpapier von Kleb- und Füllstoffen sowie von Druckerschwärze zu befreien, verwendete man bis jetzt meistens alkalische Flüssigkeiten, welche das Papier zerfallen lassen, dabei aber eine schwache Gelbfärbung der Papiermassc erzeugen, die durch Bleichmittel entfernt werden muß; auch löst sich die Druckerschwärze nur schlecht von der Faser.Used to remove adhesives, fillers and printing ink from waste paper up to now mostly alkaline liquids have been used, which cause the paper to disintegrate, but with a slight yellow coloration produce the pulp that must be removed by bleach; also dissolves the printing ink is bad from the fiber.
ίο Es wurde gefunden, daß das Papier leichler zerfällt, wenn man es in wäßrigen Lösungen der Enzyme der Bauchspeicheldrüse behandelt. Man vermeidet dabei auch das Gelbwcrden der Papicrmassc, so daß Bleichung unnötig ist, und außerdem löst sich die Druckerschwärze leicht von der Faser, so daß sie mit Wasser leicht weggeschlämmt werden kann. Man kann diese Enzyme in alkalischer, neutraler und schwach saurer Lösung wirken lassen, kann auch zur Unterstützung der Wirkung Salze in verschiedenen Konzentrationen zusetzen und wird überhaupt von den bekannten Erfahrungen über die die Enzymewirkung begünstigenden und hemmenden Fak-ίο It has been found that the paper is lighter disintegrates when treated in aqueous solutions of pancreatic enzymes. One also avoids that The paper mass turns yellow, so that bleaching is unnecessary, and it also loosens Printing ink lightly off the fiber so that it can be easily washed away with water can. These enzymes can work in alkaline, neutral and weakly acidic solutions can also be used to support the effect salts in various concentrations and is generally based on the known experiences about the enzyme action favoring and inhibiting factors
a5 torcn sachgemäßen Gebrauch machen.a5 torcn make proper use of it.
Statt der Enzyme der Bauchspeicheldrüse kann man auch ähnlich wirkende Enzyme anderer Herkunft anwenden, z. B. Papayotin, Rizinusferment und andere.Instead of the enzymes of the pancreas one can also use enzymes with a similar effect use another origin, e.g. B. papayotin, castor ferment and others.
An Stelle der kostspieligen Daucrpriipanile kann man ebenso die frischen Organe oder Pflanzenteile verwenden. Auch kann man die bekannten wasser- und säurcunlösliehen FaI-lungsprodukte, wie beispielsweise die mit dem. Bauchspcicheldrüsefcrmcnt erhaltene Gerbsäurcfällung verwenden, die bei der Einwirkung schwacher Alkalien eine wirksame Enzymelösung liefert.,Instead of the expensive permanent priipaniles you can also use the fresh organs or parts of plants. You can also do that known water- and acid-insoluble precipitation products, such as the one with the. Pancreatic Tannic Acid Precipitation use, which provides an effective enzyme solution when exposed to weak alkalis.,
Am besten verwendet man die Enzyme der Bauchspeicheldrüse, da diese leicht und vorhältnismäßig billig zu beschaffen sind. Es sind für die Wirkung sehr geringe Mengen Enzyme notwendig. Z. B. kann man 100 kg Zeitungspapier in 200 1 Wasser mit 20 g Pankreatin und 20 g Natriumbikarbonat in kurzer Zeit zerfallen lassen.It is best to use the pancreatic enzymes as they are light and proportionate can be obtained cheaply. Very small amounts of enzymes are required for this to work. For example, you can get 100 kg Newsprint in 200 l of water with 20 g of pancreatin and 20 g of sodium bicarbonate in a short time Let time fall apart.

Verarbeitung von Altpapier zu wieder brauchbarer Papiermasse, dadurch gekennzeichnet, daß man das Altpapier in Wasser mit den Enzymen der Bauchspeicheldrüse oder ähnlich wirkenden Enzymen behandelt. Processing of waste paper into reusable paper pulp, characterized in that that you put the waste paper in water with the enzymes of the pancreas or similarly acting enzymes.
