Description

Verfahren zur Gewinnung von Zellstoff für Papier und Pappe Es wurde gefunden, daß Pansendung zur Gewinnung von Zellstoff für Papier und Pappei geeignet ist, wenn er nach den bekannten Aufschlußmethoden, insbesondere nach dem Sulfid- oder Sulfatverfahren, aufgeschlossen wird.Process for the production of pulp for paper and paperboard It was found that Pansendung is suitable for the production of pulp for paper and cardboard is, if he is after the known digestion methods, especially after the sulfide or sulphate process.

Um die im Pansenidung enthaltene Magensäure zu entfernen, wird der Punsendung, so wie er im Schlachthof anfällt, kurze Zeit mit einer etwa o;3 bis o,5o/oigen Alkalilösung behandelt. .Danach wird der Dung, gegebenenfalls nach erfolgtem Absieben und nochmaligem Zerkleinern, in der üblichen Weise, insbesondere nach dem bekannten Sulfid-bzw. Sulfatverfahren, aufgeschlossen:.To remove the gastric acid contained in the rumen, the Puncture consignment, as it occurs in the slaughterhouse, for a short time with an approximately o; 3 to 0.5% alkali solution treated. Then the manure, if necessary after Sieve and grind again, in the usual way, especially after known sulfide or. Sulphate process, unlocked :.

Der fertig aufgeschlossene Pansendung stellt einen Zellstoff dar, der für die Herstellung von Papier und Pappe geeignet ist. Er kann auch in bekannter Weise durch Farbzusatz gefärbt oder unter Verwendung von Natrium- oder Calciumhypochlorit gebleicht werden.The fully opened Pansendung represents a cellulose, which is suitable for the production of paper and cardboard. He can also be known in Colored by adding color or using sodium or calcium hypochlorite to be bleached.
