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.
