摘要： One or more of these or other problems are improved using a method of making a strong gypsum panel which includes a method for forming a hardened shell structure at the interface of a foamed bubble and a gypsum slurry. A strengthening component is selected from the group consisting of set accelerators, water soluble polyphosphate salts, blends of water soluble polyphosphate salts with starch, boric acid, fibers, glycerin or combinations thereof. The strengthening component is combined with a foaming agent and with water to form an aqueous soap mixture. Foam is generated from the aqueous soap mixture, and added to a gypsum slurry. Allowing the strengthening component to contact the soap bubbles prior to addition of the foam to the gypsum slurry allows the strengthening component to preferentially contact the soap film rather than be dispersed through the entire slurry.

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.

摘要： A method for providing a smoothly mixed slurry to a web is provided which includes inserting calcined gypsum and water into a mixer (12), agitating the contents of the mixer (12) to form an aqueous dispersion of the calcined gysum, and passing the agitated contents from an outlet (20) of the mixer (12) into a slurry dispensing apparatus (22) including a flexible, resilient conduit (24). Additionally, the method includes the step of creating a back-pressure on the mixture in the slurry dispensing apparatus by constricting the conduit (24). The constricting of the conduit (24) is effected by a constrictor valve (28) located on the conduit (24).
