摘要： Coated nonwoven fibrous mats, building panels, and methods for making the same are provided. A coated nonwoven fiber mat includes a nonwoven fibrous mat having a continuous barrier coating on a surface thereof. The continuous barrier coating includes a set composition of gypsum and a binder. A building panel includes a panel core associated with a coated nonwoven fiber mat. A method of making a coated nonwoven fibrous mat includes depositing a composition of water, gypsum stucco, and a binder onto a surface of a nonwoven fibrous mat and setting the composition to form a continuous barrier coating.

摘要： In one aspect, a method of making a gypsum panel includes depositing an aqueous liquid containing a wetting agent onto a fiberglass mat, such that the aqueous liquid penetrates an entire thickness of the fiberglass mat, and depositing a gypsum slurry onto the fiberglass mat onto which the aqueous liquid has been deposited, such that the gypsum slurry penetrates at least a portion of the fiberglass mat. In another aspect, a method of making a gypsum panel includes depositing an aqueous liquid containing a wetting agent onto a fiberglass mat, and depositing a gypsum slurry onto the fiberglass mat onto which the aqueous liquid has been deposited, prior to drying of the aqueous liquid, such that the gypsum slurry penetrates at least a portion of the fiberglass mat.

摘要： A lightweight gypsum wallboard having a foamed gypsum core reinforced with pre-gelatinized, e.g., pre-gelled, starch and prepared by mixing an aqueous foam into a gypsum slurry comprising a source of calcined gypsum (commonly known as plaster of Paris), pre-gelled starch and a lignosulfonate dispersant; allowing the so-formed gypsum slurry to set, and then drying the set gypsum core.

摘要： Gypsum based compositions, processes for making same, and articles made therefrom. In one example, the gypsum based composition can include about 1.5 wt % to about 3 wt % of a starch, about 11 wt % to about 14 wt % of a paper, about 0.7 wt % to about 2.3 wt % of vermiculite, about 1.3 wt % to about 3 wt % of a plurality of reinforcing fibers, about 7 wt % to about 10 wt % of a binding agent, about 2 wt % to about 4 wt % of perlite, and about 65 wt % to about 75 wt % of a calcium sulfate, where all weight percent values are based on a combined weight of the starch, paper, vermiculite, plurality of reinforcing fibers, binding agent, perlite, and calcium sulfate.
