In der Patentanmeldung R27159VIb/55b ist ein Verfahren zur Verhütung des Absetzens von Harz bei der Herstellung von Papier aus Sulfitzellstoff beschrieben, das dadurch gekennzeichnet ist, daß dem Sulfitzellstoff 0,05 bis 0,5 Gewichtsprozent (berechnet auf das Gewicht der Breifeststoffe) eines Polymeren aus 80 bis 100 Gewichtsprozent N-Vinyl-2-pyrrolidinon in dem Stadium unmittelbar vor dem Kochen bis unmittelbar vor dem Stoffauflauf einverleibt werden.In the patent application R27159VIb / 55b is a Described method for preventing the settling of resin in the manufacture of paper from sulphite pulp, which is characterized in that the sulfite pulp contains 0.05 to 0.5 percent by weight (calculated based on the weight of the pulp solids) of a polymer composed of 80 to 100 percent by weight of N-vinyl-2-pyrrolidinone incorporated at the stage just before cooking to just before the headbox will.

Es wurde nun gefunden, daß zur Erreichung des gewünschten Effektes die Menge des zugesetzten Polymeren bis auf 0,005 Gewichtsprozent, vorzugsweise 0,02 bis 0,05 Gewichtsprozent, herabgesetzt werden kann. Das Absetzen von Harz kann mit diesen Mengen erfolgreich durchgeführt werden, insbesondere sind die verwendeten Polymeren besonders geeignet in den Fällen, in denen eine Kontrolle des Harzabsetzens unbedingt wesentlich ist.It has now been found that to achieve the desired effect, the amount of added Polymers reduced to 0.005 percent by weight, preferably 0.02 to 0.05 percent by weight can be. Settling of resin can be carried out successfully with these amounts, in particular The polymers used are particularly suitable in those cases where a control resin settling is essential.

Beispielexample

Ein Holzbrei mit einer Konsistenz von 3,5 °/o aus 454 kg gebleichtem Kraftstoff und 544 kg gebleichtem Sulfit, 2,27 kg eines Harzleims, der eine kleine Menge eines Addukts aus einem Harz und Maleinsäure enthält, 301 einer Klebstofflösung (11,34 kg/ 196,821) und 1,8 kg Natriumaluminat wurde in heißem Wasser entfasert und dann 2 Stunden lang bei 77101 C gemahlen. Dann gab man 36,3 kg Titaniumdioxydpigment und 18 kg Alaun zu. Eine Lösung, die 0,24% (4,54 kg/189,25 1) eines Homopolymeren von N-Vinyl-2-pyrrolidinon mit einem K-Wert von 30 enthielt, wurde kurz vor den Flügelpumpen (wo der Brei eine Konsistenz von 0,5 °/o aufwies) mit einer Menge von 1,78 1 Lösung in der Minute dem Brei zugesetzt. Dies entspricht 0,038 °/o des Homopolymeren, bezogen auf das Gewicht der Faser in dem Brei. Man erzielt dabei eine ausgezeichnete harzdispergierende Wirkung. Tatsächlich beträgt die Menge des normalerweise verwendeten Harzdispergierungsmittels (Natriumsalz eines sulfonierten Kondensats aus Formaldehyd und Naphthalin), die zur Erzielung guter Ergebnisse erforderlich ist, 0,38 % des Dispergierungsmittels, bezogen auf das Gewicht des Papierbreis.A wood pulp with a consistency of 3.5% made from 454 kg of bleached fuel and 544 kg of bleached sulfite, 2.27 kg of a resin glue containing a small amount of an adduct of a resin and maleic acid, 301 of an adhesive solution (11.34 kg / 196.821) and 1.8 kg of sodium aluminate were defibrated in hot water and then milled at 77 101 C for 2 hours. Then 36.3 kg of titanium dioxide pigment and 18 kg of alum were added. A solution containing 0.24% (4.54 kg / 189.25 l) of a homopolymer of N-vinyl-2-pyrrolidinone with a K value of 30 was just before the vane pumps (where the slurry had a consistency of 0.5%) was added to the slurry at a rate of 1.78 liters of solution per minute. This corresponds to 0.038% of the homopolymer based on the weight of the fiber in the slurry. An excellent resin-dispersing effect is achieved. In fact, the amount of resin dispersant normally used (sodium salt of a sulfonated condensate of formaldehyde and naphthalene) required for good results is 0.38% of the dispersant based on the weight of the pulp.

Bemerkenswerte Vorteile erzielt man dann, wenn die Menge des N-Vinyl-2-pyrrolidinon-Polymeren auf etwa 0,02 "/o, bezogen auf die Faser, herabgesetzt wird.Notable advantages are achieved when the amount of N-vinyl-2-pyrrolidinone polymer is increased about 0.02 "/ o based on the fiber is decreased.
