Abstract
Un proceso para la fabricación de yeso calcinado en forma de suspensión o polvo. El proceso incluye la adición a la suspensión de al menos dos tipos de modificadores de fase cristalina. El primer modificador de fase cristalina es para controlar la morfología del cristal del yeso calcinado (tal como ácido succínico y/o ácido málico). El segundo modificador de fase cristalina es para prevenir o retrasar el fraguado para controlar el tiempo de fraguado (tal como el pirofosfato tetrasádico (TSPP)) para formar un producto estable en agua. Un acelerador es típicamente adicionado en el lugar de uso para las aplicaciones específicas tal como compuesto de unión tipo fraguado, moldeo de medios, recubrimientos exterior/interior e ignífugos en spray. También se describen: una composición hecha por el proceso y un kit para utilizar tal composición.
