摘要： The invention concerns a method for producing gypsum boards, wherein a liquefier for the gypsum slurry is foamed with gas to provide a foam having a water content of less than 85 wt.-%, then incorporated into a gypsum/water mixture and the mixture thus obtained is applied on a two dimensional substrate. The incorporation of the liquefier in foamed form allows for a significant reduction of the amount of liquefier required to provide a desired flowability of the gypsum/water mixture, thus allowing the production of gypsum boards with similar characteristics with less liquefier. The invention further concerns gypsum board prepared using this process, apparatuses for producing gypsum boards using this process and the use of a corresponding liquefier foam to minimize the amount of liquefier required to establish a desired flowability of a gypsum/water mixture.

摘要： The present invention is concerned with plasterboards including at least two layers A and B of different composition, wherein layer A includes a calcium sulfate binder and a synthetic polymer foam and the layer B includes a calcium sulfate binder and a surfactant foam and wherein the at least one layer A is a surface layer. Improved nail pull resistance can be achieved in lightweight plasterboards, if foamed synthetic polymer is present in a surface layer. The present invention further concerns a method for the production of corresponding products, an apparatus for the production of such products as well as the use of synthetic polymer foam in a surface layer to produce plasterboards with high nail pull resistance at a minimal amount of synthetic polymer.
