    摘要： A paper product may include high energy thermomechanical pulp (TMP), low energy TMP, and microfibrillated cellulose. The paper product may also include inorganic particulate material. A papermaking composition suitable for making the paper product, a process for preparing the paper product, and use of microfibrillated cellulose may include high energy TMP, low energy TMP, and microfibrillated cellulose, and optionally inorganic particulate material. The microfibrillated cellulose may have a fiber steepness of from about 20 to about 50 in the paper product.

    摘要： Described herein is nanocellulose produced by introducing a mixture of cellulose based fiber raw material and water through a refining gap, having a width smaller than 0.1 mm. In the refining gap, the fiber raw material is subjected to processing forces varying in the direction of introducing said mixture, by means of refining zones provided in the gap one after each other in the feeding direction, whereby the refining surfaces differ in surface patterning and/or surface roughness. The mixture of fiber raw material and water is guided past the refining surfaces in the feeding direction to different locations in the refining zone by by-pass channels provided in the stator. The width of the refining gap is maintained by the combined effect of the feeding pressure of the mixture of fiber raw material and water fed into the refining gap and the axial force of the rotor.

    摘要翻译： 本文描述的是通过将纤维素纤维原料和水的混合物通过宽度小于0.1mm的精炼间隙引入的纳米纤维。 在精炼间隙中，纤维原料在进料方向上通过在间隙中设置的精炼区，在引入所述混合物的方向上施加变化的加工力，由此精炼表面在表面图案化和 /或表面粗糙度。 纤维原料和水的混合物通过设置在定子中的旁通通道在进料方向上引导到精炼区中的不同位置。 精炼间隙的宽度通过纤维原料和进料到精炼间隙的水的混合物的进料压力和转子的轴向力的组合效应来保持。

    摘要： A method of making pulp adapted to be used in forming corrugating medium is disclosed. The method comprises cooking woodchips in a first liquor in the absence of an alkali addition. The method further comprises mechanically fiberizing the woodchips to form a pulp. The method further comprises separating hydrolyzate from the pulp. The method further comprises treating the pulp with a second liquor, the second liquor including at least one alkali. The method further comprises refining the pulp.

    摘要： The invention combines the step of adding chemicals such as alkaline peroxide to an intermediate line after refining, with the step of applying chemicals such as alkaline peroxide as a pre-treatment before primary refining and/or applying chemicals such as alkaline peroxide at the primary refiner. This is implemented in the preferred embodiment, by pre-treating feed material, refining the materials into a pulp in a superatmospheric refiner, and adding chemicals in the post refining blowline.
