    Abstract: Effective use of dispersants in wallboard containing foam results from a method where stucco is mixed with a first dispersant and a first quantity of water to form a gypsum slurry. A soap is blended with a second dispersant and a second quantity of water to make a foam. Subsequently, the foam is combined with the slurry. Choice of different first and second dispersants and their relative amounts allows control of the size distribution of the foam bubbles in the slurry and the resulting voids in the gypsum core. Melamine sulfonate condensate and polycarboxylate dispersants are preferred dispersants.

    Abstract: The application concerns a gypsum board (10) and a method of producing it whereby the board comprises a gypsum core (20) and at least one mat (12) being provided on the core. The mat has outer (14) and inner (18) surfaces and comprises a first region (30) adjacent to the outer surface defined along a horizontal plane of the mat, the first region having a first substantial thickness, and a second region (32) adjacent to the inner surface defined along a horizontal plane of the mat, the second region having a second substantial thickness. The first region has more hydrophilicity than the second region, more wettability than the second region, and/or less density than the second region.

    Abstract: Disclosed is a method of preparing a mat-faced cementitious article composite. A mat-faced article (e.g., board) is formed and the composite is formed upon application of a finish composition (e.g., hydrophobic). In one aspect, the matfaced gypsum article comprises a mat having an inner surface adjacent to a cementitious core first surface and an opposite outer mat surface. An aqueous cementitious finish composition is applied to the outside mat surface to form the matfaced cementitious article composite. Desirably, the finish composite can suitably be applied by a roller assembly comprising a finish roller. In some embodiments, the finish roller has an uneven surface, including for example, grooves or depressions (e.g., circumferential or longitudinal) defined therein.

    Abstract: One or more of these or other problems are improved using a method of making a strong gypsum panel which includes a method for forming a hardened shell structure at the interface of a foamed bubble and a gypsum slurry. A strengthening component is selected from the group consisting of set accelerators, water soluble polyphosphate salts, blends of water soluble polyphosphate salts with starch, boric acid, fibers, glycerin or combinations thereof. The strengthening component is combined with a foaming agent and with water to form an aqueous soap mixture. Foam is generated from the aqueous soap mixture, and added to a gypsum slurry. Allowing the strengthening component to contact the soap bubbles prior to addition of the foam to the gypsum slurry allows the strengthening component to preferentially contact the soap film rather than be dispersed through the entire slurry.
