摘要： 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.

摘要： 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.

摘要： A ready-mixed setting type joint compound in which formation of gypsum seeds has been inhibited. A method for controlling a setting reaction by mixing a ready-mixed setting type joint compound with one or more metal ion control agents comprising aminopolycarboxylic acid and/or a salt thereof, and further mixing the setting type joint compound with one or more non-calcium phosphate compounds. The method may further comprise mixing the setting type joint compound with a set activator obtained by blending together a first set activator including a cadmium compound, lead compound and/or zinc compound and a second set activator including a ferrous compound, aluminum compound and/or manganese compound.
