Gypsum fiberboard panel as well as method and apparatus for the production of a gypsum fiberboard panel
Abstract The invention relates to a method for production of a gypsum fiberboard panel (2), having the following method steps: - production of a mixture (13) of calcined gypsum (14) and fibers (15), - application of the mixture (13) to a gas-permeable and/or air-permeable and/or liquid-permeable conveying means (3a) that continuously moves in an advancing direction (A), at an advancing speed (VA), - pre-compaction of the mixture (13), - wetting of the mixture (13) with setting water, - post-compaction of the mixture (13), - pressing the mixture (13) to form a gypsum fiberboard panel strand, - cutting the gypsum fiberboard panel strand into individual gypsum fiberboard panels (2), - drying the gypsum fiberboard panels (2), - if necessary, finishing and/or coating the dried gypsum fiberboard panels (2), wherein for pre-compaction, the mixture (13) is sprayed with a water mist (23) and has a partial vacuum applied to it. The invention furthermore relates to an apparatus (1) for production of a gypsum fiberboard panel (2), in particular for carrying out the method, as well as to a gypsum fiberboard panel (2) produced using the method and/or using the apparatus (1).
