摘要： The present invention is directed to a gypsum panel and a method of making such gypsum panel. For instance, in one embodiment, the gypsum panel comprises a gypsum core and a first facing material and a second facing material sandwiching the gypsum core, wherein the gypsum core includes gypsum and one or more components of a reclaim gypsum panel, such as reclaimed gypsum and reclaimed facing material. The methods of the present invention are directed to making the aforementioned gypsum panels by providing the first facing material, providing a gypsum slurry comprising gypsum, water, and one or more components of a reclaim gypsum panel, such as reclaimed gypsum and reclaimed facing material, onto the first facing material, and providing a second facing material on the gypsum slurry.

摘要： The present invention is directed to a gypsum panel and a method of making such gypsum panel. For instance, in one embodiment, the gypsum panel comprises a gypsum core and a first facing material and a second facing material sandwiching the gypsum core, wherein the gypsum core includes gypsum and an alkoxylated compound. In another embodiment, the gypsum panel comprises a gypsum core and a first facing material and a second facing material sandwiching the gypsum core, wherein the gypsum core includes gypsum and a polyol compound and wherein the gypsum panel exhibits a humidified deflection of greater than 0 inches to 0.05 inches. The methods of the present invention are directed to making the aforementioned gypsum panels by providing the first facing material, providing a gypsum slurry comprising gypsum, water, and the respective compound onto the first facing material, and providing the second facing material on the gypsum slurry.
