摘要： A composition and method for treating a set gypsum-containing material are disclosed. The composition is formed from at least water at least one trimetaphosphate salt, at least one monobasic phosphate salt, and at least one acyclic polyphosphate salt having at least three phosphate units. The method comprises applying to a set gypsum material at least two of the following inorganic phosphates: at least one monobasic phosphate salt, at least one trimetaphosphate salt, and at least one acyclic polyphosphate salt having at least three phosphate units. The method can be for inhibiting re-calcination of a set gypsum containing material, and/or for enhancing the strength, surface hardness, paintability, abrasion resistance, and/or water erosion resistance of a set gypsum-containing material. Also disclosed is a method of making a set gypsum-containing material.

摘要： A cementitious article and a method of making a cementitious article are disclosed. The cementitious article comprises a cementitious component that comprises a polyvinyl acetate type polymer, a monobasic phosphate, and optionally boric acid. Cementitious articles, such as board, are prepared such that the polyvinyl acetate type polymer, the monobasic phosphate, and optionally boric acid can be present in the cementitious core, and/or in dense layers if present. The concentration of the polyvinyl acetate type polymer, monobasic phosphate, and optionally boric acid in the cementitious article can increase from a central region A to peripheral regions B and C, respectively. In some embodiments, the polyvinyl acetate type polymer is a polyvinyl alcohol and the monobasic phosphate is monoammonium phosphate.

摘要： Polymerization of siloxane is improved using a gypsum-based slurry that includes stucco, Class C fly ash, magnesium oxide and an emulsion of siloxane and water. This slurry is used in a method of making water-resistant gypsum articles that includes making an emulsion of siloxane and water, then combining the slurry with a dry mixture of stucco, magnesium oxide and Class C fly ash. The slurry is then shaped as desired and the stucco is allowed to set and the siloxane polymerizes.The resulting product is useful for making a water-resistant gypsum panel having a core that includes interwoven matrices of calcium sulfate dihydrate crystals and a silicone resin, where the interwoven matrices have dispersed throughout them a catalyst comprising magnesium oxide and components from a Class C fly ash.

摘要： A process for making calcined gypsum in slurry or powder form. The process includes adding at least two types of crystal modifiers to the slurry. The first crystal modifier is to control crystal morphology of the calcined gypsum (such as succinic and/or malic acid). The second crystal modifier is to prevent or retard setting to control set time (such as tetrasodium pyrophosphate (TSPP)) to form a water stable product. An accelerator is typically added at the site of use for specific applications such as setting type joint compound, media casting, exterior/interior coating, and sprayable fireproofing. A composition made by the process and a kit for using the composition are also disclosed.

摘要： A method of continuously forming a multilayer panel includes making a gypsum slurry, then dividing the gypsum slurry into at least a primary gypsum slurry and a secondary gypsum slurry. An additive slurry having water and an intumescent material is created, then added to the secondary gypsum slurry to make an expandable layer slurry that is spread over at least a portion of a facing material. The primary gypsum slurry is distributed over the secondary gypsum slurry over the facing material and the expanding layer slurry to form a core. Optionally, another layer, an edge coating, is applied to the expanding layer for additional fire protection. The edge coating includes a second intumescent material. During a fire, the expanding layer expands to increase the thickness of the fire exposed gypsum panel and the edge coating expands to seal the gap between adjoining gypsum panels.
