摘要： A process for manufacturing a web material is disclosed. The process generally provides the steps of: a. providing a pulp material comprising fibers and vessels; b. separating said vessels from said fibers in said pulp material to form a slurry having at least about 7 percent less vessels per meter than said pulp material; and c. processing said slurry to form said web material.

摘要： A method for controlling a fiber fractionation system for fractionating an input material into a long fraction (LF) stream comprising LF fibers and a short fraction (SF) stream comprising SF fibers includes measuring an average LF fiber length at one or more locations post-fractionation, and maintaining the average LF fiber length within a target variability range by automatically altering a rotational speed of a rotor of the fiber fractionation system.

摘要： A device for compacting stacked sheets of chemical, mechanical, or recycled fibre pulp, or pulp slabs from a preceding slab press into preferably prism-shaped bales in a press, with a device for feeding the pulp to the press. It is primarily characterized in that a press unit is provided in the form of a mechanical toggle press. This can replace the commonly-use hydraulic system and greatly reduces the amount of maintenance required.

摘要： The invention relates to a method for producing particles of mineral material comprising grinding of at least one mineral material in the presence of water. The grinding according to the invention is carried out in the presence of at least one polymer obtained by a radical polymerization reaction of a partial sodium salt of itaconic acid and partial decarboxylation of the polymer obtained followed by partial or total neutralization of the decarboxylated polymer. The invention also relates to an aqueous composition comprising particles of ground mineral material and such a polymer, in particular a mass-loading composition for the production of paper or a paper-coating-colour composition.

摘要： A device for compacting pulp flocks into slabs or preferably prism-shaped bale in a press with a device for feeding the pulp to the press with a least one buffer chute. The press unit is provided in the form of a mechanical toggle press and at least one pre-compaction unit. This can replace the commonly-used hydraulic system and greatly reduces the amount of maintenance required. In addition, it can shorten the cycle time and thus increase production.

摘要： The invention relates to a method for reducing starch content of an aqueous phase, which is removed from a fibre stock preparation in a manufacturing process of paper, board, tissue or the like. The fibre stock preparation comprises a thickening step, where a fibre stock comprising cellulosic fibres originating from recycled fibre material and/or broke as well as starch dispersed in an aqueous phase is thickened from a first concentration to a second concentration by removing a part of the aqueous phase from the fibre stock. A cationic polymer obtained by copolymerisation of (meth)acrylamide and at least 25 mol-% of solely cationic monomer(s), having a standard viscosity SV of at least 1.7 mPas, is added to the fibre stock at the latest at the thickening step in order to associate the starch with the cellulosic fibres of the fibre stock.
