Description

Verfahren zur Herstellung eines für die Zellstoff-Fabrikation geeigneten Halbproduktes aus grünen Steppen-, Sumpf- und Riedgräsern und ähnlichen Pflanzenarten. Die--Erfindung bezweckt ein Verfahren zur Herstellung eines für die Herstellung von Zellstoff geeigneten Halbproduktes aus Gras-, Schilf- und ähnlichen Pflanzenarten und besteht darin, daß die grünen Pflanzenstoffe durch mechanische Aufschließung in gewöhnlichem Wasser in Rohfasern verwaii.-delt werden. Dieses Verfahren hat den Vorteil, daß es auch in unkultivierten Gegenden, wo die in Betracht kommenden Pflanzenarten in reichsten Vorkommen vorhanden sind, mit: einfachsten Mitteln ausgeführt erden kann.Process for the production of one suitable for pulp manufacture Semi-product from green steppe, marsh and sedge grasses and similar plant species. The invention aims at a method of making one for the manufacture of pulp-suitable semi-products from grass, reed and similar plant species and consists in the fact that the green plant matter is broken down by mechanical means are twisted into raw fibers in ordinary water. This procedure has the Advantage that it is also in uncultivated areas, where the plant species in question are present in the richest occurrences, with: grounding carried out with the simplest means can.

Das erzeugte Halbprodukt besteht aus wollartigen Rohfasern, die sich nicht verfilzen. Es kann in Kuchen- oder in sonstige Form gepreßt «-erden, so daß es mit geringer Raumbeanspruchung und Kosten verfrachtet «erden kann. Bei dieser Pressung wird das Halbprodukt in vorteilhafter Weise in solche Form gebracht, daß es ohne weitere Beha#idlting, z. B. Reinigen und Stampfen ini Kolier, der späteren chemischen Aufschlieliung unterworfen «erden kann. Zweckmäßig wird dem Produkt ein sterilisierender Stoff zugesetzt, um während der weiteren Lagerung und der Verfrachtung eine Fäulnisbilching zu verhindern.The semi-product produced consists of wool-like raw fibers, which are don't get matted. It can be pressed in cake or other form, so that it can be "grounded" with little space requirement and cost. At this Pressing the semi-finished product is brought in an advantageous manner in such a form that it without further handling, e.g. B. Cleaning and tamping ini Kolier, the later can be subjected to chemical decomposition. Appropriately, the product is a Sterilizing material added to during further storage and shipping to prevent putrefactive bilching.

Das nach dein neuen Verfahren hergestellte Halbprodukt enthält etwa 5o bis 6o Prozent reinen Zellstoff, während der entsprechende Gehalt in den Pflanzen selbst nur etwa 25 bis 3 5 Prozent beträgt. Infolgedessen wird bei der chemischen Aufschließung zu Zellstoff, welche durch Kochen mit kaustischer Soda oder anderen, billigeren Chemikalien bewirkt «-erden kann, bei verhältnismäßig hoher Ausbeute sowohl an Fassungsvermögen der verwendeten Apparatur als auch an der erforderlichen Chemikalienmenge erheblich gespart. Auch die Kochdauer wird beträchtlich verkürzt. Daß ferner die Füllung der Kocher mit den v orgepr eßten Stücken vereinfacht wird, wurde bereits erwähnt.The semi-finished product made by your new process contains about 5o to 6o percent pure pulp, while the corresponding content in the plants itself is only about 25 to 3 5 percent. As a result, the chemical Digestion into pulp, which is obtained by boiling with caustic soda or other, cheaper chemicals can be produced, with a relatively high yield both in the capacity of the equipment used and in the required Substantial savings in the amount of chemicals. The cooking time is also reduced considerably. That the filling of the cooker with the pre-pressed pieces is also simplified, has already been mentioned.

Das neue Verfahren kann folgendermaßen ausgeführt «-erden.The new method can be carried out as follows.

Die verwendeten Pflanzen, z. B. Steppen-, Sumpf- und Riedgräser, werden in grünem Zustande in Längen von etwa 3 bis 6 cm zerkleinert und alsdann in einen Holländer, Koller,-an g oder eine ähnlich wirkende Vorrichtung gebracht. In dieser «erden die Pflanzen in Gegenwart von gewöhnlichem, d. h. nicht besonders angewärmten Wasser aufgeschlossen. Die aufgeschlossenen Pflanzenstoffe werden während oder nach der Aufschließung ausgewaschen. Hierdurch werden alle für die chemische Aufschließung nachteiligen Bestandteile zum großen Teil fortgeschafft, während die Zellstoffe in der 'Masse zurückbleiben.The plants used, e.g. B. steppe, marsh and sedge grasses are when green, crushed into lengths of about 3 to 6 cm and then into one Holländer, Koller, -an g or a similar device brought. In this «Ground the plants in the presence of ordinary, i. H. not particularly warmed up Water unlocked. The digested plant substances are during or after washed out of the unlocking. This will make all for chemical digestion detrimental constituents are largely carried away while the pulps to stay behind in the crowd.
