Abstract: Disclosed is a foam modifier, e.g., useful for gypsum or cement slurries. The foam modifier comprises a fatty alcohol that is added to a gypsum or cement slurry that includes foaming agent, such as an alkyl sulfate surfactant. The fatty alcohol can be a C6-C16 fatty alcohol in some embodiments. The use of such a foam modifier can be used, for example, to stabilize the foam, reduce waste of foaming agent, improve void size control in the final product, and improve the gypsum board manufacturing process.

Abstract: Disclosed is a composite gypsum board comprising a hoard core and a concentrated layer of substantial thickness (e.g., at least about 0.02 inches). The concentrated layer includes a higher weight percentage of an enhancing additive than the board core. The board core has a thickness greater than the thickness of the concentrated layer and forms the bulk of the board volume. The concentrated layer has a higher density (e.g., at least about 1.1 times greater) than the density of the board core. Also disclosed is a method of preparing a composite gypsum board.

Abstract: A gypsum slurry includes water, a hydraulic component including calcium sulfate hemihydrate and a linear polycarboxylate dispersant. The linear polycarboxylate anionic dispersant includes a first monomeric repeating unit and a second monomeric repeating unit. The first repeating unit of the linear polycarboxylate dispersant is an olefinic unsaturated carboxylic acid repeating unit or salt thereof. The second repeating unit of the linear polycarboxylate dispersant is a vinyl sulfonate. The slurry can be made into a gypsum panel. Methods of making gypsum slurry and a gypsum panel are also disclosed.

Abstract: A method for making a gypsum board including: combining a first plurality of particles including at least about 50 wt. % calcium sulfate dihydrate and about 0.05 wt. % to about 10 wt. % hydrophobic material and having a D50 particle size of about 200 μm to about 800 μm with a second plurality of particles including calcium sulfate hemihydrate to form a combined mixture of calcium sulfate; adding water to the combined mixture of calcium sulfate to make an aqueous gypsum slurry; depositing a core layer including the aqueous gypsum slurry over a forming surface; and allowing the core layer to set, thereby forming a set gypsum core.

Abstract: A method and apparatus to manufacture gypsum board that directs a first portion of aqueous gypsum slurry to a front cover sheet, directs a second portion of aqueous gypsum slurry to a back cover sheet, passes the back cover sheet over a roller spaced above the front cover sheet so that a majority of the second aqueous gypsum slurry falls off the back cover sheet onto the first portion of aqueous gypsum slurry on the front cover sheet. A gypsum board made by the method or apparatus.

Abstract: Disclosed is a method and system for blending a foam modifier with foaming agent on-line, e.g., as may be particularly useful for gypsum or cement slurries. The foam modifier comprises a fatty alcohol that is added to a gypsum or cement slurry that includes foaming agent, such as an alkyl sulfate surfactant. The fatty alcohol can be a C6-C16 fatty alcohol in some embodiments. The use of such a foam modifier can be used, for example, to stabilize the foam, reduce waste of foaming agent, improve void size control in the final product, and improve the gypsum board manufacturing process.
