A sheet manufacturing method includes a web forming step of forming a web by accumulating a defibrated product in a dry manner, a moisture imparting step of imparting the web with moisture, a pressurizing step of pressurizing the web to which the moisture is imparted, and a heating step of heating the web to which the moisture is imparted, in which a water content of the web to which the moisture is imparted in the moisture imparting step is 12% by mass or more, a pressure applied to the web in the pressurizing step is 0.2 MPa or more, and a temperature of the web in the heating step is 100° C. or lower.

A compressed article formed by a composite material comprising a thermoset polymer and a wood material, a method of producing the same and the use of the novel articles. The composite material has a continuous matrix of a hardened thermoset polymer and, distributed within the matrix, wood chips which are at least partially encased by the thermoset polymer, said article having a water absorbency of less than 1% by weight upon immersion into water over a time period of at least 168 h at room temperature. The articles can be used in structures that are frequently contacted with water.

A method for producing a cellulose product from an air-formed cellulose blank structure comprising the steps; providing a cellulose blank structure which is air-formed from cellulose fibres; applying, in a first application step (S.sub.A1), an alkyl ketene dimer (AKD) dispersion to the cellulose blank structure, and applying, in a second application step (S.sub.A2) a latex dispersion to the cellulose blank structure arranging the cellulose blank structure with the applied alkyl ketene dimer (AKD) dispersion and latex dispersion in a forming mould; heating the cellulose blank structure to a forming temperature (T.sub.F) in the range of 100° C. to 300° C., and forming the cellulose product from the cellulose blank structure in the forming mould, by pressing the heated cellulose blank structure with the applied alkyl ketene dimer (AKD) dispersion and latex dispersion with a forming pressure (P.sub.F) of at least 1 MPa, preferably 4-20 MPa.

A two-part flame-retardant, a flame-retardant oriented strand (OSB) and method for forming a flame-retardant OSB is provided. The two-part flame-retardant composition includes an aqueous solution containing a water-soluble flame-retardant and a flame-retardant powder that is incorporated into an oriented strand board without substantially affecting the mechanical properties of the oriented strand board. The method includes applying the aqueous solution containing a water-soluble flame-retardant to an oriented strand board furnish and applying a flame-retardant powder to the wetted furnish, without requiring an additional drying step.

A composite wood panel is manufactured from thin wood laminae cut from wood unsuitable for peeler logs or dimensional lumber. At least one bonding agent is applied to the wood laminae, and they are formed into a randomly oriented mat that is compressed into a thin wood web that can be a corrugated web or a flat web that is permanently set in a single press operation.

A method to produce a building panel, including providing a core, applying a first paper layer on a first surface of the core, wherein the first paper layer includes a resin impregnated paper, applying refined lignocellulosic fibres on the first paper layer, applying a wood veneer layer above the refined lignocellulosic fibres, applying pressure to the core, the first paper layer, the refined lignocellulosic fibres, and the wood veneer layer to form a building panel. Also, to such building panel.

The complex of the present disclosure includes a thermoplastic particle constituted of a thermoplastic material and an inorganic particle surface-treated with at least one surface treatment agent selected from the group consisting of fluorine-containing compounds and silicon-containing compounds and further includes a composite particle composed of the thermoplastic particle and the inorganic particle adhered to the thermoplastic particle.

A manufacturing process for manufacturing wood products with acoustic dampening properties. A noise-dampening polymer is introduced in-line in the manufacturing process to achieve higher acoustic performance. The polymer can be a viscoelastic polymer which is added during blending of the lignocellulosic strands prior to mat formation, or sprayed or otherwise coated on the lignocellulosic strands during mat formation, prior to formation of any boards or panels.
