摘要： A process for the production of particle board, MDF board or HDF board includes the step of recycling particle board material, MDF and/or HDF board material in which recycled chips and/or recycled wood fibers are produced. The process includes the step in which the particle board material, the MDF and/or HDF board material is wetted, heated and pressurized, such that this material is kept under pressure and at an elevated temperature for a certain time. The process involves the step of supplying the recycled chips and/or the recycled wood fibers as base material in a production process of particle board, MDF board or HDF board.

摘要： A casket and method for manufacture of a casket is described, and more particularly, for a casket having walls constructed of fiberboard such as medium density fiberboard (MDF). The walls have outside cladding of MDF that is molded or extruded to provide surface contours such as raised and/or recessed features without having to attach such features as separate trim pieces to the walls. The resulting casket provides aesthetic characteristics and strength for use in funeral ceremonies.

摘要： A method to produce a veneer element, including defects and dense portions. The method includes providing a substrate, providing a sub-layer, including a binder and coloured filler particles, applying the sub-layer on a first surface of the substrate, applying a veneer layer on the sub-layer, and applying pressure, preferably heat and pressure, to the veneer layer and/or the substrate, thereby forming a veneer element wherein, after pressing, the sub-layer is visible through a defect of the veneer element such as crack, cavity, hole and/or knot of the veneer layer. Also, a veneer element.

摘要： A press apparatus for vehicle crash pads including real wood sheets. The press apparatus includes a lower press including an engraved part, and a support part to support an upper press, the support part having a fixing protrusion, the upper press including an embossed part, first slides fixed to maintain a shape of the engraved part during a compression process of the real wood sheet, the first slides compressing a rear surface of the real wood sheet while rising along the embossed part, and a second slide to compress the real wood sheet during the compression process of the real wood sheet. During a wrapping process of the real wood sheet, the second slide compresses the real wood sheet to an inner rear surface of a core while falling such that a portion of the real wood sheet bent inward of the engraved part is wound around the core.

摘要： A binder has at least one isocyanate and at least one biopolymer mixed with water. The biopolymer may be a biopolymer nanoparticle or cooked and chemically modified starch. Optionally, the binder may also include urea. The biopolymer and water are mixed, and the isocyanate is added to the mixture. The binder may have a viscosity that is suitable for being sprayed on a substrate to make a composite material, for example a viscosity of 700 cP or less or 500 cP or less at 40° C. The substrate may be wood, another lignocellulosic material, or synthetic or natural fibers. In particular examples, the binder is used to make no added formaldehyde wood composites including particle board and fiberboard. Alternatively, the binder may have a higher viscosity and be used to make plywood.

摘要： A multi-layer fire-resistance treatment (FRT) panel for use as structural sheathing. The wood structural panel may be OSB or plywood, coated or treated during the manufacturing process with a product that provides fire resistance. The treatment may be integrated with the material forming the wood structural panel, or may be a coating layer applied to the mat or mat layer. A burn-through layer also may be applied. A protective layer comprising a resin-impregnated paper overlay may be applied on one or both sides of the panel.
