摘要： In a method for producing nanofibrillar cellulose starting from cellulose pulp (P), where cellulose is in native form, the cellulose pulp is prebeaten by circulating it in form of aqueous suspension of fibres through a refining gap (G) formed by opposite arrays of refining bars which perform relative movement in the gap. The cellulose pulp is circulated until a beating degree of below 55 ml CSF, preferably 50 ml CSF or less, more preferably 20 ml CSF or less is attained. The prebeaten pulp is forwarded to a disintegration process (2), where the prebeaten pulp is disintegrated to nanofibrillar cellulose (NFC).

摘要： Printing paper product is made by multilayer technique starting from aqueous furnish comprising fibres and strength additive. In the aqueous furnish comprising fibres and strength additive, nanofibrillar cellulose and strength additive is fed in a middle layer to form a multilayer printing paper, and the paper product is made by dewatering of the furnish whereby the nanofibrillar cellulose and the strength additive migrate to the surface layers to increase the internal bond strength of the printing paper.

摘要： A method for making nanofibrillar cellulose includes mixing anionized or cationized cellulose fibers and cellulose pulp to a mixture including at least 1% and below 90 wt-% cellulose pulp based on dry weight, and subjecting the mixture to a refiner stage where the anionized or cationized cellulose fibers are at least partly reduced to nanofibrillar cellulose and the cellulose pulp acts as auxiliary pulp, and obtaining a mixture of nanofibrillar cellulose and cellulose pulp from the refining stage. The mixture can be used for making paper by adding it to base pulp.

摘要： In a method for producing nanofibrillar cellulose, cellulose based fibre material, in which internal bonds in cellulose fibres have been weakened by preliminary modification of cellulose, is subjected to disintegration treatment in form of pulp comprising fibres and liquid. The fibre material is supplied at a consistency higher than 10 wt-%, preferably at least 15 wt-%, to a disintegration treatment where fibrils are detached from the fibre material by joint effect of repeated impacts to the fibre material by fast moving successive elements and the weakened internal bonds of the cellulose fibres. The nanofibrillar cellulose is withdrawn from the disintegration treatment at dry matter which is equal or higher than the consistency of the fibre material. In the disintegration treatment, the fibre material is supplied through several counter-rotating rotors (R1, R2, R3 . . . ) outwards in the radial direction with respect to the rotation axis (RA) of the rotors in such a way that the material is repeatedly subjected to shear and impact forces by the effect of the blades (1) of the different counter-rotating rotors.
