Abstract: A slurry distribution system can include a feed conduit and a distribution conduit in fluid communication therewith. The feed conduit can include a first feed inlet and a second feed inlet disposed in spaced relationship thereto. The distribution conduit can extend generally along a longitudinal axis and include an entry portion and a distribution outlet in fluid communication therewith. The entry portion is in fluid communication with the first and second feed inlets of the feed conduit. The distribution outlet extends a predetermined distance along a transverse axis, which is substantially perpendicular to the longitudinal axis. The slurry distribution system can be placed in fluid communication with a gypsum slurry mixer adapted to agitate water and calcined gypsum to form an aqueous calcined gypsum slurry.

Abstract: A discharge gate is provided for delivering a mixed slurry from a gypsum slurry mixer, and includes a first extractor port configured for generating a first density slurry for a first gypsum layer, and a second extractor port configured for generating a second density slurry for a second gypsum layer. A channel is defined by a front panel and a side panel of the discharge gate for delivering the first and second density slurries from the slurry mixer. The first extractor port extends semi-tangentially from the front panel of the discharge gate, and is connected in fluid communication with the front panel via the channel and a first slurry passageway disposed within the first extractor port for delivering the first density slurry.

Abstract: Disclosed is a foam modifier, e.g., useful for gypsum or cement slurries. The foam modifier comprises a fatty alcohol that is added to a gypsum or cement slurry that includes foaming agent, such as an alkyl sulfate surfactant. The fatty alcohol can be a C6-C16 fatty alcohol in some embodiments. The use of such a foam modifier can be used, for example, to stabilize the foam, reduce waste of foaming agent, improve void size control in the final product, and improve the gypsum board manufacturing process.

Abstract: A joint tape to be applied to wallboard is provided and includes a base substrate having opposing sides. In certain embodiments, a first adhesive layer is applied to one of the sides of the base substrate and a second adhesive layer is applied to the first adhesive layer, where the first adhesive layer is different than the second adhesive layer. In certain other embodiments, two different adhesives are used in a single adhesive layer. In use, the joint tape is positioned over and removably secured to a joint or corner between adjacent wallboard panels using the first adhesive layer. After the joint tape is in position, joint compound is applied to the joint tape, and the water in the joint tape activates it to form a secure bond with the wallboard panels.
