摘要:
A building board, particularly a gypsum board, can have a high fastener sealability if protected by the combination of thin layers of an extruded polymer film and a thermoplastic coating layer. The combination of extruded polymer film and thermoplastic coating layer is designed such that the gypsum, board can also tolerate overdriven fasteners, thus exceeding the requirements of ASTM D1970-15.

La présente invention se rapporte à une plaque à base de plâtre comprenant une âme en plâtre disposée entre deux couches de revêtement dans laquelle un textile renfermant des fibres de verre et un liant organique constitue au moins une des couches de revêtement et/ou le textile est noyé dans le plâtre constituant l'âme. Dans ledit textile, le liant comprend un ou plusieurs polymères organiques ayant une température de transition vitreuse qui varie de -50 à +80°C mesurée par analyse calorimétrique différentielle selon la norme ISO 1357-1:2009.
摘要:
A wallboard panel is provided, including a sheet of face paper, a first layer of gypsum composition having a first density, a web of mesh associated with the first layer of gypsum composition, a second layer of gypsum composition having a second density, the second density being lower than the first density, and a layer of backing paper. An associated method includes providing a sheet of face paper and laying same upon a moving conveyor belt, applying a first layer of gypsum composition slurry upon the sheet of face paper, applying a web of mesh upon the first layer of gypsum composition slurry, applying a second layer of gypsum composition slurry upon the web of mesh, and applying a sheet of backing paper upon the second layer of gypsum composition slurry.
摘要:
The invention is a new soundproofing panel comprising a layer of recycled textile fibres (M), recycled wool and an aggregating polymer. The recycled wool content makes up at least 12% of the entire mass. It can be coupled on one or both of its main sides with a wood fibre panel (L), with a plasterboard panel (C), on one side with a wood fibre panel (L) onto which in turn a plasterboard panel (C) is applied, on at least one side with a sheet made of a plastic material (S) with selvedge (Sc), with a plasterboard panel (C) onto which in turn a sheet made of a plastic material (S) with selvedge (Sc) is applied, on at least one side with a rubber layer or sheet (G), on at least one side with a metal sheet or foil.

摘要:
Verwendung einer haftvermittelnden Harzmischung zur Herstellung von Laminaten sowie ein Verfahren zur Herstellung einer Haftbrücke in Form eines mit der haftvermittelnden Harzmischung beaufschlagten Trägergewebes. Bevorzugte Pre-Polymere zur Verwendung in den haftvermittelnden Harzmischungen sind Polyurethane, Polyester, Acrylate, Polyharnstoffe sowie entsprechende Copolymere oder Hybride von Polyurethanen oder Polyurethan-Copolymeren mit Acrylaten. Die erfindungsgemäßen haftvermittelnden Harzmischungen und Haftbrücken eignen sich insbesondere zur festen Verbindung zwischen einer mineralischen Trägerplatte und Dekor-, Nutz- oder Overlayschichten. Die so erhältlichen Laminate sind sowohl für den Innen- als auch den Außenbereich geeignet.
摘要:
The invention comprises a relatively lightweight cementitious-based material panel. The cementitious-based material panel comprises a foam insulating panel having a first surface and a second surface; a first structural layer of cementitious-based material formed on the first surface of the foam insulating panel and affixed thereto; and a second non-structural layer of cementitious-based material formed on the second surface of the foam insulating panel and affixed thereto. The second non-structural layer of cementitious-based material is substantially thinner than the first structural layer of concrete. The second non-structural layer of cementitious-based material is preferably formed from polymer modified concrete, plaster or mortar. A method of making the cementitious-based material panel is also disclosed.
