A method for producing a veneered board having a veneer and a carrier board having improved use properties includes the steps of providing a veneer and a carrier board, providing a sheet of paper impregnated with binder, the sheet of paper being arranged in a stack of materials to be pressed between an upper face of the carrier board and a lower face of the veneer, and pressing the stack of materials to be pressed. The sheet of paper is impregnated with a binder, the sheet of paper impregnated with binder is pre-dried so that it is still sticky, at least one additive is applied onto the pre-dried, still sticky binder, and the sheet of paper which is impregnated with binder and provided with an additive is dried to a residual moisture content of up to 8%.

A barrier material comprising (a) at least one layer of cellulosic substrate comprising MFC, and (b) a first barrier layer arranged on at least one surface of said cellulosic substrate, is provided, as well as a method for reducing the water vapour transmission rate (WVTR) of a cellulosic substrate.

Improved wood strand panels suitable for construction are produced by first thermally modifying a plurality of wood strands that are thin in terms of thickness. Then, wood veneers are constructed from the thermally modified wood strands, at least some of which partially overlap one another. The wood veneers are on the order of 0.125 to 0.25 inches thick. Finally, the wood veneers, constructed from the thermally modified wood strands, are stacked on top of one another and connected using adhesive, pressure and temperature similar to plywood or LVL manufacture. The thermal modification and use of thin strands, followed by veneer formation, prior to manufacture of the composite results in a composite with uniform density, high-strength, resistance to decay, resistance to water sorption, and other benefits.

The invention relates to a material board (1) which comprises a core (2) and a first cover layer (3) and a second cover layer (4), each of which is formed by a mixture (7, 8) formed by lignin-containing particles (5, 6) and binder, which mixture is designed to form a solid body structure in a chemical binding process. The aim is to provide a material panel, which, for ecological and economical reasons, comprises a high proportion of particles based on annual plants and still exhibits good mechanical properties. Another object of the invention can be considered that of ensuring that the system load is kept relatively low during the production process. Another object can be considered that of keeping the proportion of stock removal low. According to the invention, at least 70%, preferably at least 80%, most preferably at least 90% of the particles (5) associated with the mixture (7) of the core (2) are obtained from annual plants, and at least 70%, preferably at least 80%, most preferably at least 90% of the particles (6) associated with the mixtures (8) of the two cover layers (3, 4) are obtained from perennial plants. The invention further relates to the use of a material board and to a method for producing a material board. Finally, the invention relates to a system for producing a material board.

The present invention describes a method for thermo-treatment of wood, where said method comprises the following steps: a) selecting the wood to be as free from knots as possible b) introducing the wood to a temperature increase up to approximately 173° C.; c) maintaining the wood at an ambient temperature of 173° C. for 3-5 hours; d) decreasing the temperature to approx. 20° C.; e) introducing the wood into an autoclave wherein a mixture of linseed oil and mineral oil is applied to the wood, and allowing the mixture to penetrate the wood f) retrieving and storing the treated wood. Furthermore a timber member made with wood treated according to the method is disclosed.

A method to produce a panel. The method includes providing a core having a first surface, providing a surface layer including a substantially uncured amino resin, applying an hydrolysable adhesive on the first surface of the core and/or on a surface of the surface layer adapted to face the core, arranging the surface layer on the first surface of the core, pressing the surface layer to the core to form a panel by applying heat and pressure in a press, thereby adhering the surface layer to the core by the hydrolysable adhesive and curing the amino resin of the surface layer. Also such a panel.
