  • Method for producing MDF boards with NFC/MFC
    Patent number: 10953568
    Abstract: The invention relates to a method for the production of MDF boards, fibre and particle boards, based on cellulose fibres, comprising the following steps: obtaining wood chips; transporting them to a vaporizer silo where they are heated; transporting the wood chips to a digester where they continue to be heated and are conveyed via a supply outlet screw towards a shredder/refiner; adding a paraffinic emulsion to the chips; transporting them towards the shredder/refiner; injecting resin; carrying to a dryer; transporting towards a fibre silo; carrying the fibres to a step of forming, pre-pressing, pressing, measuring, classification, cooling, standing, formatting and packaging of the boards produced, wherein nanofibrillated cellulose (NFC) is added, together with microfibrillated cellulose (MFC), be it in the supply screw, or after the shredder/refiner, or after the dryer.
    Type: Grant
