Beschreibung
Zusammenfassung:	There are provided gypsum panels, sheets and multi-layer sheets as well as methods of preparation thereof. For example, there are provided cellulose filament-reinforced gypsum panels, sheets and multi-layer sheets and methods of preparation thereof. For example, in such gypsum panels, sheets and multi-layer sheets gypsum is bound with cellulose filaments to strengthen the gypsum panels, sheets and multi-layer sheets. The cellulose filament-reinforced gypsum panel can be, for example, a core comprising a honeycomb or corrugated structure. There are also provided aqueous suspensions comprising cellulose filaments and CaSO42H2O. L'invention concerne des plaques, des feuilles et des feuilles multicouches en gypse, ainsi que leurs procédés de préparation. Par exemple, l'invention concerne des plaques , des feuilles et des feuilles multicouches en gypse renforcées par des filaments de cellulose et leurs procédés de préparation. Par exemple, dans de telles plaques , feuilles et feuilles multicouches en gypse, du gypse est lié avec des filaments de cellulose pour renforcer les plaques, feuilles et feuilles multicouches en gypse. La plaque en gypse renforcée par des filaments de cellulose peut être, par exemple, une âme comprenant une structure en nid-d'abeilles ou ondulée. L'invention concerne également des suspensions aqueuses comprenant des filaments de cellulose et du CaSO42H2O.
