    Abstract: A process for producing a lignocellulose-containing, plastic-coated and printable molding (26), in particular in sheet form, comprising the steps of: a) producing a layer (A, B?) containing lignocellulose-containing particles according to the shape of the molding to be produced (26); b) applying a layer (C) of particles containing electron beam-reactive thermoplastic onto the layer produced according to the preceding feature; c) heating the layers (A, C) produced according to the preceding features such that thermoplastic particles melt into the layer containing lignocellulose-containing particles (Cs); d) pressing the layers heated according to feature (1c); and e) irradiating the layers pressed according to feature (1d) with electrons in the energy range from 1 MeV to 10 MeV. The process is for example elucidated with reference to an MDF sheet one-sidedly provided with a polymer layer.

  • Publication number: 20220033656
    Abstract: The invention relates to a method and devices for producing products (65) by using cellulose-containing particles, with which the following steps are carried out: a) irradiating the particles with electrons in the energy range >1 MeV: b) mixing the irradiated particles with electron-beam-reactive powder of a synthetic polymer, in particular a thermoplastic, having powder particle sizes <2000 micrometres and/or with a liquid electron-beam-reactive synthetic or bio-based polymer; c) forming the mixture created in a way corresponding to the form of the product to be produced, in particular forming it into a nonwoven (56): d) heating the formed mixture to 100-180° C.; e) pressing the formed mixture without heating; and f) irradiating the pressed mixture with electrons in the energy range of 1 MeV to 10 Me V and also with appropriately chosen dosages and dosing rates.
