    摘要： A gypsum slurry is described that includes water, a hydraulic component comprising at least 50% calcined gypsum by weight based on the dry weight of the hydraulic component, foam, a defoamer, a polycarboxylate dispersant having olefinic unsaturated mono-carboxylic acid moieties and (poly)oxyalkylene moieties, a first portion of a retarder and a second portion of a retarder. In some embodiments of the invention, the defoamer is combined with the dispersant prior to being added to the gypsum slurry. The defoamer and dispersant can be added as a physical mixture, wherein the defoamer is attached onto the dispersant polymer, or a combination thereof. In some embodiments, a gypsum building panel is made from the gypsum slurry.

    摘要： A flow splitter (200) can include an inlet conduit (202) and first and second outlet conduits (204, 206) separated by a junction portion (210). The inlet conduit (202) can include an inlet end (203) and a junction end (205). The inlet conduit (202) is disposed along a main flow axis (75) extending between the inlet end (202) and the junction end (205). The inlet end (203) defines an inlet opening (207). The junction end (205) defines first and second junction openings (209, 211). The first junction opening (209) is disposed in spaced relationship to the second junction opening (211). The junction portion (210) is disposed at the junction end (205) of the inlet conduit (202) between the first and second junction openings (209, 211). The junction portion (210) includes a substantially planar wall region (219) that is substantially perpendicular to the main flow axis (75). The flow splitter (200) can be placed in fluid communication with a cementitious slurry mixer (102) and a slurry distributor (104) with the flow splitter (200) disposed therebetween.

    摘要： 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.
