    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 transporting nanofibrillar cellulose in the form of viscous liquid dispersion, the nanofibrillar cellulose is unloaded from a container (3) through a discharge point (3b) which is the lowermost point with respect to the volume of nanofibrillar cellulose in the container at least at the time of unloading. The nanofibrillar cellulose is unloaded and transported to a target location along a pipe (2) using a progressive cavity pump (P2) operating on a positive displacement principle with the suction side of the pump at a distance from the discharge point (3b). The discharge of the nanofibrillar cellulose is ensured by selecting the distance (L) of the suction side of the pump (P2) from the discharge point (3b) so short that the nanofibrillar cellulose flows from the container (3) by the effect of the pump suction, or pressurizing the nanofibrillar cellulose in the container (3) to such a pressure (p) that it will flow at the selected distance (L) of the suction side from the discharge point by the common effect of the pressure of the nanofibrillar cellulose and the pump suction.

    摘要: Method for making modified cellulose products comprises—processing cellulose pulp to modified cellulose pulp at a manufacturing location to increase the susceptibility of fibers to disintegration,—setting the modified cellulose pulp to a suitable dry matter content, and—transporting the modified cellulose pulp at set dry matter content to a location of use, where the modified cellulose pulp is disintegrated to nanofibrillar cellulose.

    摘要: The object of the present invention is a method for making mechanical pulp, such as thermomechanical or chemi-thermomechanical stock. The mechanical pulp is used as a raw material for printing paper, and its freeness value is 30-70 ml CSF. The stock refined by the method is screened in several stages to form accept and reject stock portions. The wood raw material is refined at the first stage of refining at a superatmospheric pressure of over 400 kPa to form a stock that has a freeness value of 250-700 ml CSF.
