Abstract: A wallboard panel is provided, including a sheet of face paper, a first layer of gypsum composition having a first density, a web of mesh associated with the first layer of gypsum composition, a second layer of gypsum composition having a second density, the second density being lower than the first density, and a layer of backing paper. An associated method includes providing a sheet of face paper and laying same upon a moving conveyor belt, applying a first layer of gypsum composition slurry upon the sheet of face paper, applying a web of mesh upon the first layer of gypsum composition slurry, applying a second layer of gypsum composition slurry upon the web of mesh, and applying a sheet of backing paper upon the second layer of gypsum composition slurry.

Abstract: Disclosed is a composite gypsum board comprising a board core and a concentrated layer of substantial thickness (e.g., at least about 0.02 inches). The concentrated layer includes a higher weight percentage of an enhancing additive than the board core. The board core has a thickness greater than the thickness of the concentrated layer and forms the bulk of the board volume. The concentrated layer has a higher density (e.g., at least about 1.1 times greater) than the density of the board core. Also disclosed is a method of preparing a composite gypsum board.
Abstract translation: 公开了一种复合石膏板，其包括板芯和基本厚度的浓缩层（例如，至少约0.02英寸）。 浓缩层包括比板芯更高重量百分比的增强添加剂。 板芯的厚度大于浓缩层的厚度，并形成板体的体积。 浓缩层具有比板芯的密度更高的密度（例如，至少约1.1倍）。 还公开了一种制备复合石膏板的方法。

Abstract: Disclosed is a composite gypsum board comprising a board core comprising set gypsum sandwiched between face and back cover sheets. The composite gypsum board also comprises an intermediate sheet between the board core and the face cover sheet, with a thin, dense gypsum layer disposed between the intermediate sheet and the face cover sheet. Optionally, a second dense gypsum layer can be disposed between a first major side of the board core and the back cover sheet. Also disclosed is a method of preparing a composite gypsum board in which an intermediate sheet is applied over a dense gypsum layer disposed on a face cover sheet. A back cover sheet is applied to the other major side of the board core, with a second dense gypsum layer optionally disposed therebetween.

Abstract: Disclosed is a composite gypsum board comprising a hoard core and a concentrated layer of substantial thickness (e.g., at least about 0.02 inches). The concentrated layer includes a higher weight percentage of an enhancing additive than the board core. The board core has a thickness greater than the thickness of the concentrated layer and forms the bulk of the board volume. The concentrated layer has a higher density (e.g., at least about 1.1 times greater) than the density of the board core. Also disclosed is a method of preparing a composite gypsum board.

Abstract: Disclosed are methods relating to an extruded pregelatinized, partially hydrolyzed starch prepared by mixing at least water, non-pregelatinized starch, and acid to form a starch precursor. The acid can be a weak acid that substantially avoids chelating calcium ions or a strong acid in a small amount. In the method, pregelatinization and acid-modification of the starch precursor occurs in one step in an extruder. Also disclosed are methods of preparing board using the starch prepared according to the methods, as well as starches and boards prepared by various methods of the invention.
