摘要： The invention relates to methods of producing microfibrillated cellulose (MFC). According to the invention a fibrous pulp suspension is fibrillated mechanically at a consistency of less than 12.5%, dewatered to raise the consistency of the fibrillated suspension to at least 12.5%, and then subjected in the dewatered condition to further fibrillation. Alternatively an initially fibrillated fibrous pulp suspension may be dewatered and fibrillated in the dewatered condition, after which these dewatering and fibrillating steps are repeated one or more times so that pulp consistency is increased for each fibrillation step. The goals of raising the consistency between subsequent fibrillations are energy saving and an increased aspect ratio in MFC. The invention even comprises uses of the MFC product, e.g. as an additive for papermaking furnish or injection molded plastic composites.
摘要翻译：本发明涉及微纤化纤维素（MFC）的制造方法。根据本发明，纤维纸浆悬浮液以小于12.5％的稠度机械原纤化，脱水以将原纤化悬浮液的稠度提高至至少12.5％，然后在脱水条件下进一步原纤化。或者，最初原纤化的纤维纸浆悬浮液可以在脱水条件下脱水和原纤化，之后将这些脱水和原纤化步骤重复一次或多次，以使每个原纤化步骤的纸浆稠度增加。提高后续原纤化之间的一致性的目标是在MFC中节能和增加的纵横比。本发明甚至包括MFC产品的用途，例如，作为造纸配料或注塑塑料复合材料的添加剂。

摘要： A method for the production of highly refined or microfibrillated cellulose (MFC), comprising the steps of treating cellulosic fibres to remove at least a major part of the primary wall of the fibres, drying the treated fibres, rewetting the treated fibres, and disintegrating the wetted fibres by mechanical means to obtain the final product. Dried cellulosic pulp is produced as an intermediate product of the method, having an average fibre length of at least 0.4 mm, while less than 50% of the primary wall material of natural untreated fibres is left in the intermediate product. Instead of transporting large amounts of dilute MFC dispersion the invention enables transport of the dry intermediate product to the MFC end user, who would complete the process by turning the intermediate product to final MFC by use of standard disintegrating devices.

摘要： This invention relates to water-based well drilling fluids. It has been found that cellulose based particles, which comprise cell wall material and their networks of cellulose based fibers and nanofibrils can be used to produce suspensions having viscosity and rheological properties particularly suitable for use as a drilling fluid. It is assumed that the organization of the cellulose fibrils, as it exists in the parenchymal cell walls, is at least partly retained in the cellulose based particles of the invention, even though part of the pectin and hemicellulose is removed there from. Breaking plant-based pulp down into this kind of cellulose based particles involves fewer and gentler processes than to break the pulp down further into cellulose nanofibrils, and therefore the present cellulose based particles can be produced much faster and at lower cost than completely unraveled cellulose nanofibrils. The well drilling fluids based on the cellulose material of this invention are stable over a wide range of operating temperatures.
