Abstract: A combined wooden frame support and ceiling system is provided, each support including upper and lower wooden chords and a wooden structure connecting the lower chord to the upper chord for weight bearing purposes. A gypsum wallboard batten strip is attached to the lower chord, and defining a ledge extending from each side of the lower chord. A single thickness of gypsum wallboard panels is used to create a ceiling attached to the support, each panel used to create the ceiling is made from a slurry composition including less than 5% by weight of Grade 4 vermiculite. Upon the support being assembled in the ceiling system, with a plurality of the supports, and having lengths of insulation supported by the ledges of the adjacent supports, the ceiling system resists charring by fire for at least one hour.

Abstract: A slurry distributor includes a feed conduit and a distribution conduit in fluid communication therewith. The feed conduit includes an entry segment with a feed inlet and a feed entry outlet in fluid communication therewith and extending along a first feed flow axis. The feed conduit includes a shaped duct having a bulb portion in fluid communication with the feed entry outlet. The feed conduit includes a transition segment in fluid communication with the bulb portion and extending along a second feed flow axis in non-parallel relationship with the first feed flow axis. The bulb portion has an area of expansion with a cross-sectional flow area that is greater than a cross-sectional flow area of an adjacent area upstream from the area of expansion. The shaped duct has a convex interior surface in confronting relationship with the feed entry outlet of the entry segment.

Abstract: Disclosed are a gypsum board, and related slurries and methods. The gypsum board comprises a gypsum layer disposed between two cover sheets. The gypsum layer comprises a crystalline matrix of set gypsum and expandable graphite. The expandable graphite exhibits volume expansion at high temperatures. Optionally, unexpanded vermiculite can also be included in the gypsum layer to provide an expansion component at even higher temperatures. Because of synergy between the expandable graphite and unexpanded vermiculite in accordance with some embodiments, less vermiculite can be included in the board than in conventional board that contained vermiculite. The board desirably can pass one or more fire-related tests, and is a fire-rated board in some embodiments.
Abstract translation: 公开了一种石膏板以及相关的浆料和方法。 石膏板包括设置在两个覆盖片之间的石膏层。 石膏层包含凝固石膏和可膨胀石墨的结晶基质。 可膨胀石墨在高温下表现出体积膨胀。 任选地，未膨胀的蛭石也可以包含在石膏层中以在甚至更高的温度下提供膨胀组分。 由于根据一些实施方式的可膨胀石墨和未膨胀蛭石之间的协同作用，与包含蛭石的传统板相比，可以将更少的蛭石包括在板中。 理想地，电路板可以通过一个或多个与火相关的测试，并且在一些实施例中是防火板。
