摘要： The method relates to a method for producing a wood material panel. The method includes the following steps: (a) scattering a multitude of wood particles to produce a particulate cake, (b) applying an adhesive to at least some of the wood particles during the scattering and/or prior to the scattering, and (c) pressing of the particulate cake under high pressure and at a high temperature, wherein a quantity of adhesive that is applied to the wood particles is varied depending on its anticipated position in the particulate cake.

摘要： The disclosure relates to a method for producing a wooden composite material board in particular an MDF or HDF board, wherein a cake made of wood chips or wood fibres wetted with a binder is spread, which is subsequently pressed in a hot press to form a board of a desired thickness, wherein, before the pressing, a mixed powder made of colour pigments and a second binder is spread onto an upper side of the cake as a primer, wherein the cake is sprayed with water after the spreading of the mixed powder.

摘要： The invention relates to a method for producing an OSB, wherein a scattered mat formed by strands adhered in multiple layers is pressed in a hot press to form a panel with a desired thickness, comprising the following steps: a) scanning the surface of an upper side of the mat or of the pressed panel to determine uneven areas and/or faults; b) determining position data of the determined uneven areas and/or faults; c) determining the volumes of the individual uneven areas and/or faults; d) targeted filling of the uneven areas and/or faults with a filling material, based on the determined position data and volumes, wherein e) the filling material is scattered with a scattering device.

摘要： The present invention relates to a method for producing wood materials from lignocellulose-containing crushed products, in particular for producing wooden insulating panels or OSB boards, wherein in order to decrease or reduce the emission of volatile organic compounds (VOC) and, if relevant, very volatile organic compounds (VVOC), including terpenes, acids and aldehydes, said wood materials are treated with a combination of additives during production. According to the invention, the treatment is carried out with a first component made of porous carbon and a second component, a hydrogen sulphite salt. The invention further relates to wood materials that can be obtained using the method according to the invention, having reduced emissions of VOCs, including terpenes, acids and aldehydes. Finally the present invention relates to the use of a combination of additives, formed by a first component with a porous carbon and a second component made of hydrogen sulphide salt, for decreasing or reducing the emission of VOCs from wood materials during or after production thereof from lignocellulose-containing crushed products.
