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。

Abstract: A system and method for predicting wallboard fire performance in a standard test includes procuring a sample of the wallboard for testing, and mounting the sample into a fixture so that one side of the sample is exposed to a heat source. A cavity is created between the sample and the fixture such that the sample is disposed between the heat source and the cavity. A temperature measurement is taken at a predetermined location within the cavity over time, and the temperature is monitored and recorded as a series of temperature readings using a computer-readable medium. The series is analyzed to determine an index time at which the temperature reaches a predetermined temperature threshold. The index time is correlated to a standard-test fire performance using the computer-readable medium and, based on the correlation, a fire performance of the wallboard in a standard test procedure is predicted.
