    摘要: Cellulose nanofilaments from cellulose fibers, a method and a device to produce them are disclosed. The nanofilaments are fine filaments with widths in the sub-micron range and lengths up to a couple of millimeters. These nanofilaments are made from natural fibers from wood and other plants. The surface of the nanofilaments can be modified to carry anionic, cationic, polar, hydrophobic or other functional groups. Addition of these nanofilaments to papermaking furnishes substantially improves the wet-web strength and dry sheet strength much better than existing natural and synthetic polymers. The cellulose nanofilaments produced by the present invention are excellent additives for reinforcement of paper and paperboard products and composite materials, and can be used to produce superabsorbent materials.

    摘要: The invention relates to a method of controlling quality of pulp. Pulp formed in mechanical defibering of wood is screened into at least two fractions, the accept that has passed the screening phase being forwarded for further use and the reject that did not pass the screening being removed from the screening phase. The invention comprises determining flow amount and consistency of the pulp supplied to the screening phase and, correspondingly, of the reject removed therefrom, and calculating a passage ratio of the reject and the supplied pulp by means of the flow amounts and consistency values verified through the measurement, and adjusting the screening phase according to said passage ratio.

    摘要: The present invention relates to a method of reducing the loss of mineral fractions in the treatment of broke in paper production. The invention relates in particular to the treatment of the so-called broke from a paper machine, which is reusable raw material, so that as much as possible of the mineral fractions the broke contains may be returned to the process and used as raw material for paper as efficiently and economically as possible. According to the invention, the material containing minerals is dispersed into broke pulp which is fractionated, and the accept from the fractionation is returned to the paper manufacturing process, and the mineral fraction obtained as reject from the fractionation is treated separately before it is reused as filler or coating material in the production of paper or board.

    摘要: The invention relates to a process for directing a papermaking pulp towards a regulated outlet (9). Accept from successively arranged cleaning stages (6, 14, 20) is lead towards the outlet (9), while the respective rejects are lead to the inlet of the succeeding cleaning stage (14, 20). Depending on the operational situation, the accept from the cleaning stages (6, 14, 20) is totally or partly lead towards the outlet (9) while excess accept is lead in the opposite direction to the inlet (5) of the preceding cleaning stage (6). The invention also relates to an arrangement for the feeding of a forming wire, wherein a collecting accept pipe (8) is provided for extending between the outlet (9) and a feeding (3) for fresh pulp, while reject pipes (11, 18) lead to the next cleaning stage (14, 20). The invention further relates to a cleaning arrangement, wherein the accept outlets from the respective cleaning stages (6, 14, 20) are consecutively connected to a common base pipe (8) whose one end (8a) is connected to the regulated outlet (9) and whose opposite end (8b) is connected to an inlet (5) to the first cleaning stage (6).

    摘要: Das Verfahren dient zum Fraktionieren einer Papierfasersuspension (S) und ist sowohl auf Altpapier- als auch auf Frischzellstoffsuspensionen anwendbar. Es umfasst mindestens einen Faserlängentrennschritt (1) sowie mindestens einen weiteren Trennschritt (2, 3). Dabei ist der weitere Trennschritt (2, 3) so ausgelegt, dass die Papierfasern gezielt bezüglich ihrer Flexibilität in eine Hartfraktion (R2, R3) und eine Weichfraktion (A2, A3) aufgeteilt werden. Vorteile hat das Verfahren z.B. bei der Trennung von Gemischen aus chemischem Zellstoff und mechanischem Holzstoff oder bei der Trennung von Gemischen aus Früh- und Spätholz.
