Abstract: A system is provided for robotically placing dunnage strips for receiving wallboard panels, including providing a robot with a robot arm with a tool having at least one suction cup and a glue dispenser; presetting in the robot a plurality of dunnage location programs, each associated with a particular wallboard panel size or thickness; and providing a dunnage cube with a plurality of stacked dunnage strips. Upon the selection of a preset wallboard panel dunnage location, the robot arm uses the suction cup to select and lift a strip from dunnage cube. Then, the robot arm places the strip upon the warehouse floor in a predesignated location per the preset program, and the glue dispenser on the robot deposits glue upon the strip. The robot repeats the dunnage strip selection, lifting, placement and deposition of glue to multiple dunnage strips until the preset arrangement is completed per the program.

Abstract: Disclosed are gypsum boards, slurries, and methods of preparing gypsum board using water, uncalcined gypsum, stucco, and starch binder. The board contains a set gypsum core disposed between two cover sheets. The uncalcined gypsum and starch binder surprisingly and unexpectedly allows for the use of uncalcined gypsum while maintaining desired characteristics in gypsum wallboard, such as low board weight, sufficient strength, score/snap, fire resistance, etc. In embodiments, the presence of the uncalcined gypsum with the starch binder in the core slurry allows for excluding an amount of stucco therein.

Abstract: Gypsum boards formed from synthetic gypsum and other gypsum sources having high chloride salt concentrations. Gypsum boards may include a board core including set gypsum between a front cover sheet and a back cover sheet. A total concentration of the chloride anion in the board core ranges from about 150 to 4000 parts by weight (pbw) chloride, typically about 300 to about 3000 pbw, more typically from about 400 to about 2000 pbw, further typically from about 1000 to about 2000 pbw, and further typically from about 600 to about 1000 pbw, per 1,000,000 pbw calcium sulfate dihydrate. A polymer layer contacts an inner surface of the back cover sheet. A densified gypsum layer contacts an inner surface of the front cover sheet. Methods of making the gypsum board, and a wall system for employing the gypsum boards, are also provided.

Abstract: Embodiments of a system and a method for manufacturing calcined gypsum can include an in-line calcination control device having an x-ray analyzer. The x-ray analyzer is adapted to analyze at least one of the calcined gypsum being discharged from the calciner and the calcined gypsum being fed into a mixer of a gypsum boardline. The x-ray analyzer is configured to determine the proportion of different calcium sulphate phases found therein which can be used to control at last one of the calciner and the boardline.
