摘要： The invention provides a method of controlling retention on a forming fabric in a paper making process, an intermediate product for use in the method, as well as use of material for the intermediate product. For making the intermediate product at least one paper making chemical is added to a slurry of fine cellulose fibres such as micro fibrillated cellulose (MFC), the specific surface area of those fibres being larger than that of the fibres of the main fibrous suspension for paper making, causing the paper making chemical being adsorbed on the fine cellulose fibres. This intermediate product is then incorporated in the main fibrous suspension before the suspension is supplied from the paper machine head box to the forming fabric. Other paper making chemicals may be added to the fibrous suspension before or after addition of the intermediate product, so that interactions between different chemicals are prevented. The invention permits an increased retention in general as well as improved control of retention of paper making chemicals separately and/or in relation to each other.

摘要： The invention relates to a packaging board comprising a fibrous base and one or more polymer coating layers on one or both sides of the fibrous base. According to the invention the fibrous base contains the combination of an alkyl ketene dimer size, stearic acid anhydride, a wet-strength size and an aluminium compound, which give the board resistance to aggressive liquids as well as thermal treatment, particularly an improved resistance to raw edge penetration in such circumstances. The invention further relates to containers and packages made of the board, for instance disposable drinking cups, dairy product cartons and auto-clave packages, as well as use of the board for such purposes.

摘要： The invention relates to treatment of thermally modified wood. Thermal modification means controlled heating treatment of wood most appropriately under moist atmosphere so as to improve the dimensional stability and decay resistance of the wood. In accordance with the invention, the water absorption tendency of themally modified wood is reduced by treating the wood with a hydrophobic sizing agent reactive with cellulose, the treatment resulting in water-repellent wood. The wood can be treated with a solution containing a sizing agent, and then the solvent is evaporated by drying. Suitable sizing agents comprise alkyl ketene dimers (AKD) and alkenyl succinic acid anhydrides (ASA) dissolved in acetone, for instance. When ASA is used, the dried wood impregnated with the sizing agent requires an additional heating treatment in order to become hydrophobic.
