The stucco material generally includes a high salt impurity content, for example, when the stucco is calcined from certain sources of low-quality synthetic gypsum. For example, in some embodiments, the salts are chloride salts, e.g., sodium chloride (NaCl), potassium chloride (KCl), magnesium chloride (MgCl2), and/or calcium chloride (CaCl2). The board and methods improve the bond between the gypsum layer(s) and at least one of the cover sheets (e.g., the back cover sheet). Also provided are methods and systems relating to drying gypsum board.

SLURRY COMPRISING ACID-MODIFIED FLOUR, GYPSUM BOARD MADE FROM THIS SLURRY AND METHOD TO MAKE THIS GYPSUM BOARD
Disclosed is an acid-modified flour and a method of making the acid- modified flour. The acid-modified flour is desirably prepared using a dry milling process. A starting flour is combined with a strong acid to form a mixture. The mixture is heated. A neutralizer is added to increase the pH of the mixture. If desired, the mixture can be dried and any agglomerates can be removed. The acid-modified flour can be used as a binder in a slurry for preparing one or more gypsum layers in a gypsum board. Claimed is a method of making gypsum board comprising: (a) forming an acid-modified flour (b) adding the acid-modified flour to at least water and stucco to form a slurry; (c) disposing the slurry to form a gypsum board core between a first cover sheet and a second cover sheet to form a wet assembly; (d) cutting the wet assembly into the gypsum board; and (e) drying the gypsum board. Claimed is a slurry comprising water, stucco, and at least one acid- modified flour having a hot water viscosity of from 50 BU to 420 BU, as measured according to the HWVA test.
