Abstract

The present disclosure relates generally to methods of analysing and manufacturing gypsum panels (100), for example, suitable for use as building surface products. The present disclosure relates more particularly to a method of forming a gypsum panel (100). The method includes forming a porous slurry layer (144) on a receiving surface (102) using a plurality of operating parameters, and allowing the porous slurry layer (144) to set to form a gypsum core (104) of a gypsum panel (100). The panel is then cut (e.g. by a router 128) to form a cut surface (108) that extends through the gypsum core (104), and an image of a region of the cut surface (108) is captured by a camera (152). The image is analysed to identify bubbles intersecting the cut surface (108). A measure of bubble contact in the gypsum core (104) is then calculated from the identified bubbles in the image. Based on the measure of bubble contact, an operating parameter used for forming the porous slurry layer (144) is modified.

Abstract

The present invention relates to a system and method for the production of gypsum board using starch pellets. In accordance with the present disclosure, the starch necessary for board formation is provided in the form of starch pellets. These pellets are mixed with a gypsum slurry in a mixer. The pellets are initially insoluble and do not dissolve. However, during subsequent drying stages, the pellets become soluble and dissolve into the gypsum phase. This both provides the desired starch component and also results in the formation of voids within the set gypsum.

Abstract

Disclosed is a building board construction that provides enhanced acoustical properties. In one possible embodiment, the board is a gypsum board with opposing facing sheets and an intermediate set gypsum core. An opened celled polymeric sheet is formed within the gypsum core and gives the resulting board enhanced sound absorption. In an alternative embodiment, individual pieces of polymeric foam are used in stead of the polymeric sheet. Also disclosed are various manufacturing methods whereby boards with enhanced acoustical properties can be formed in an continuous process. The various components of the present disclosure, and the manner in which they interrelate, are described in greater detail hereinafter.

Abstract

The present invention relates to a system and method for the production of gypsum board using starch pellets. In accordance with the present disclosure, the starch necessary for board formation is provided in the form of starch pellets. These pellets are mixed with a gypsum slurry in a mixer. The pellets are initially insoluble and do not dissolve. However, during subsequent drying stages, the pellets become soluble and dissolve into the gypsum phase. This both provides the desired starch component and also results in the formation of voids within the set gypsum.

Abstract

A system for visually enhancing a surface. For example, the system may include an assembly that may be configured to project a laser line across at least a portion of the surface. Versions of the laser line may be projected at an angle of incidence relative to a plane defined by the surface. For example, the angle of incidence may be in a range of about 5 degrees to about 60 degrees. In one version, the laser line may be substantially perpendicular to a central axis of the surface. In addition, the laser line may enable enhanced, qualitative user visualization of the surface and non-planar distortion in the surface.

Abstract

A building board, particularly a gypsum board, can have a high fastener sealability if protected by the combination of thin layers of an extruded polymer film and a thermoplastic coating layer. The combination of extruded polymer film and thermoplastic coating layer is designed such that the gypsum board can also tolerate overdriven fasteners, thus exceeding the requirements of ASTM D1970-15.
