摘要： The invention provides a method of producing a filler comprising calcium carbonate (PCC), preferably to be used in paper or paper board production or in fibre based composites. The method of the invention comprises the steps of; —providing fly ash generated in paper or paper board production; —fractionating said fly ash in at least one step, whereby a coarser fraction is separated from a finer fraction; —forming a suspension of said coarser fraction; —adding carbon dioxide to said suspension to form precipitated calcium carbonate. The method of the invention avoids problems with high amounts of arsenic and heavy metals in the production of filler comprising PCC, when using ash generated in paper or paper board production as a raw material. It has been shown that harmful elements, such as arsenic and heavy metals, are primarily accumulated in the finer fractions of the fly ash. Thus, by using the coarser fraction in the step of carbonation, the amount of arsenic and heavy metals in the final product is reduced.

摘要： The present invention provides multi-ply creped tissue products, and in particular embodiments creped wet pressed tissue products, having substantially higher per-ply basis weights, such as from about 20 to about 30 gsm, without the negative effects often associated with higher basis weight. As such, the tissue products are generally soft and flexible, having a softness value (measured as TS7) less than about 12.0 and a Stiffness Index less than about 20. While being soft and flexible, the instant tissue products are durable enough to withstand use, such as having a GMT greater than about 600 g/3″ and a Burst Index greater than about 12.0.

摘要： Polymer-coated, heat-sealable liquid packaging board that resists solvents (e.g. strong alcoholic drinks), method of manufacturing board, and drinking cup made of board. Resistance to solvents is achieved by lowering raw edge penetration into the board. The fiber base of the board contains at least 1.3 kg of hydrophobic size containing alkyl ketene dimer and at least 1.0 kg of wet-strength size per 1 ton of dry matter. Fiber base density is 630-800 kg/m3. The amount of heat-sealable polymer in the top layer is higher than the Bristow wheel roughness volume of the uncoated fiber base and/or at least 14 g/m2. When manufacturing the board, the alkyl ketene dimer size and a wet-strength size are added into the stock. The pH of the tail water is adjusted so as to be alkaline (about 7 or more).
