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.

摘要： A method includes masking at least one hole of an article with a paste, wherein the hole opens onto a surface of the article, applying a coating to the surface of the article, and removing the paste including contacting the paste with water, leaving at least one open hole in the surface of the coated article. The paste includes about 40-80 wt % of a filler material, about 0.5-20 wt % of an inorganic binder, about 0.5-15 wt % of a polyhydroxy compound and about 5-25 wt % of water. The filler material includes a first material which includes alkali metal doped alumina, zirconium oxide, titanium oxide, silicon dioxide, or a combination thereof and a second material which includes a silicate. A weight ratio between the first and second materials is in a range of about 1-10.

摘要： There is provided a gypsum composition for a drying type coating material, the gypsum composition, when made into a gypsum-based coating material by addition of water, capable of forming a coating film in which color unevenness is suppressed even though the coating film is thin and smooth. This gypsum composition for a drying type coating material contains hemihydrate gypsum having a mean particle diameter of 50 μm or less, calcium carbonate having a mean particle diameter of 50 μm or less, and a setting retarder, wherein the gypsum composition has a content of calcium carbonate of 100 to 400 parts by mass and a content of the setting retarder of 0.1 parts by mass or more each based on 100 parts by mass of the hemihydrate gypsum.

摘要： Compositions comprising crosslinked polysaccharides, particularly levan and/or dextran, may provide advantageous benefits when admixed with concrete blends. Suitable compositions may comprise a biologically sourced surfactant, and a crosslinked polysaccharide, in which the crosslinked polysaccharide comprises at least one crosslinking group bonded via ether linkages to a first polysaccharide chain and a second polysaccharide chain. Concrete blends may comprise such compositions, a cement and water. Methods for forming and/or using the concrete blends may comprise allowing the concrete blends to form a hardened mass.
