摘要： An apparatus for calcining gypsum including a housing having a bottom wall, open top, and a plurality of side walls extending therebetween. A fixture is located adjacent the open top for receiving gypsum from a source and transferring the gypsum into the housing. At least one burner is connected to the housing and operable for combusting an air-fuel mixture to heat the gypsum. At least one serpentine burner conduit extends from the burner through the housing and terminates through a support floor of the apparatus. The exhaust flow is then directed through a fluidization pad and into the gypsum to further heat the gypsum product. An agitation mechanism is operable to mix the gypsum adjacent the fluidization pad to prevent pockets of gypsum from coagulating and preventing fluidization of the gypsum.

摘要： A mold resistant gypsum panel having improved mold- and fungal-resistance to the gypsum panel facing paper is provided. Mold-resistant gypsum panels include a gypsum core formed from a gypsum slurry that has voids as a result of foaming of the gypsum slurry. A first paper is located on one side of the gypsum core and a second paper opposes the first paper. A first paper comprises at least one liner ply and at least one filler ply. A second paper also comprises at least one liner play and at least one filler ply. The first and second papers may be substantially the same. At least one of the first paper and the second paper also includes a biocide having 75% retention of the biocide. Also included in at least one of the first and second paper are a retention aid and a sizing agent.
