    摘要： An acoustical panel is made by applying a thin, acoustically-transparent coating to an acoustical base mat. A pulp is made from one or more fillers, a fibrous filler, a binder and water. A thickener solution is prepared from a thickener and water. A portion of the pulp and the thickener solution are mixed under high shear conditions to degrade the fibrous filler and form a smooth coating. The coating is applied to and distributed over a base mat and the coated base mat is then cut and dried to form a coated acoustical panel. The panel is free of visible mineral nodules on the surface of the coating. Optionally, the pulp is a portion of a pulp used to make the base mat. Other embodiments include the use of recycled dust or fine particles of the acoustical panel obtained from cutting or shaping the base mat or coated panels.

    摘要： A cementitious mixture comprises a hydraulic cement; greater than about 10% by weight of a pozzolanic cement replacement selected from fly ash, slag, natural pozzolans, and mixtures thereof, based on the weight of said hydraulic cement and cement replacement; and a compatabilizing admixture, wherein the compatabilizing admixture comprises a compatabilizing derivatized polycarboxylate polymer dispersant capable of acting as a water reducer, in combination with an accelerator. The derivatized polycarboxylate dispersant, alone or in combination with other derivatized polycarboxylate dispersants, is a polymer comprising units derived from at least one of a substituted carboxylic acid monomer and a substituted ethylenically unsaturated monomer, at least one of an N-polyoxyalkylene maleimide and a condensation product of an unsubstituted carboxylic acid monomer and an alkoxypolyoxyalkylene primary amine substituted carboxylic acid monomer, and optionally including an unsaturated hydrocarbon. The derivatized polycarboxylate dispersant provides for a longer shelf life dispersant, improved dispersability of cementitious mixtures, water reduction in cementitious mixtures, and is an effective dispersant in high pozzolan replaced cementitious mixtures.

    摘要： Effective use of dispersants in wallboard containing foam results from a method where stucco is mixed with a first dispersant and a first quantity of water to form a gypsum slurry. A soap is blended with a second dispersant and a second quantity of water to make a foam. Subsequently, the foam is combined with the slurry. Choice of different first and second dispersants and their relative amounts allows control of the size distribution of the foam bubbles in the slurry and the resulting voids in the gypsum core. Melamine sulfonate condensate and polycarboxylate dispersants are preferred dispersants.
