| 20080216936 | CEILING TILE CONSTRUCTION - A ceiling tile of gypsum and cellulose fibers formed into a board by initially mixing the fibers and gypsum in a water-based slurry that is felted and thereafter pressed and dried with a desired board thickness, the dried board being processed to form a plurality of holes in a face thereof through at least the majority of the thickness of the board, the collective volume of the holes being sufficient to reduce the weight of the board by at least 10% and increase the NRC exhibited by the board over that which would otherwise be found in a board of the same composition without such holes. | 09-11-2008 |
| 20090173464 | ACOUSTIC CEILING TILES MADE WITH PAPER PROCESSING WASTE - A composition and process suitable for making acoustic tiles are disclosed. Certain embodiments of the composition comprise: perlite; inorganic material selected from the group consisting of calcium sulfate, calcium carbonate, clay and mixtures thereof; a binder selected from the group consisting of starch, a combination of starch and cellulosic fibers, latex, kraft paper gel and mixtures thereof; optionally mineral wool; optionally gypsum; and cellulosic fiber, wherein at least a portion of the cellulosic fiber and at least a portion of the inorganic material are pulp and paper processing waste comprising cellulosic fiber, clay and calcium carbonate. Certain embodiments of the process comprise: forming an aqueous slurry; continuously flowing slurry onto a moving foraminous wire to form a cake; dewatering the cake to form a base mat; and drying the base mat. | 07-09-2009 |
| 20090273113 | Wallboard and Ceiling Tile and Method of Manufacturing Same - Disclosed is a method of producing a composite material suitable for the manufacturing of gypsum wallboard and ceiling tile applications, produced by co-calcining dihydrate (gypsum) to hemihydrate/stucco and cooking of unmodified/raw starch to cooked starch together. The method disclosed improves the standard wallboard and ceiling tile processing techniques thereby lowering the manufacturing cost of both products. The co-calcining of gypsum and the unmodified starch together eliminates the calcining of dihydrate ground gypsum (powder natural or synthetic gypsum) and cooking of unmodified starch (powder) separately prior to using the materials in the wallboard and ceiling tile formulations. The unmodified starch can be also added to the gypsum rocks during the grinding and calcining process to produce composite material. Furthermore, unmodified starch can be added to the wet synthetic gypsum such as FGD (flue gas desulphurization etc.), dried or dried and calcined together. The use of composite material in both product formulations eliminates or minimizes the processing steps and lowers the energy cost by partially or completely replacing standard hemihydrate/stucco and starch during the processing. | 11-05-2009 |
