    摘要: The present invention relates to a method of making a fiber-reinforced cementitious composite material which finds widespread applicability in a variety of construction and related applications. The composite comprises cellulosic fibrous material in order to provide the composite with the desired performance characteristics. Notably, at least a portion of the cellulosic fibrous material comprises surfaced enhanced pulp fiber, which desirably enhances the processing characteristics of the material, as well enhancing the characteristics of the finished composite product. The method of making a fiber-reinforced cementitious composite comprising the steps of providing a cementitious composition, and providing cellulosic fibrous material. The present method further includes blending the cementitious composition and the cellulosic fibrous material to form the cementitious composite. The surface enhanced pulp fiber preferably comprises approximately 1-10%, by weight, of the cellulosic fibrous material, and the cellulosic fibrous material exhibits an enhanced Bauer-McNett long fiber fraction. The cellulosic fibrous material preferably exhibits at least a 10% increase in length-weighted average fiber length (LWAFL), in comparison to a cellulosic fibrous material which is devoid of surface enhanced pulp fiber. The cellulosic fibrous material requires relatively reduced refining energy, in comparison to a cellulosic fibrous material which is devoid of surface enhanced pulp fiber, to reach a predetermined freeness CSF (Canadian Standard Freeness) value.

    摘要: Methods for production of yeast biomass and removal of sugar from red liquor by propagating yeast on sugars in red liquor byproduct of the sulfite pulping process are disclosed. Yeast are propagated using the sugars in red liquor as a carbon source, thereby consuming the sugars and producing a composition of lignosulfonates that has a reduced sugar content. Disclosed methods allow for separation of sugars from lignosulfonates in red liquor without costly ultrafiltration or nanofiltration processes and also produce valuable yeast biomass.

    摘要: The present invention relates to a method of making a paper product having Improved printing characteristics. This is achieved by forming a fibrous substrate, and applying a surface treatment which comprises an aqueous composition. Notably, the aqueous composition includes surface enhanced pulp fibers, with the placement of the surface enhanced pulp fibers optimizing their functionality, with surface placement by use of a paper machine size press desirably facilitating a reduction in the typical starch usage. The present method comprising the steps of providing a aqueous slurry comprising a blend of cellulosic fibers and water and dewatering the aqueous slurry of cellulosic fibers and water to form a fibrous substrate. The present method further includes applying a surface treatment to the fibrous substrate, wherein the surface treatment comprises an aqueous composition including surface enhanced pulp fibers, to form a treated fibrous substrate, and thereafter drying the treated fibrous substrate to form a paper product having enhanced printing characteristics.
