LIGHTWEIGHT WALLBOARD COMPOSITIONS CONTAINING NATURAL POLYMERS |
摘要 |
<p>Compositions useful for the preparation of lightweight, high strength wallboards, and methods of making same are disclosed. The composition includes a slurry of calcium sulfate hemihydrate (stucco), water, starch, and a foam. The foam acts to provide large bubbles within the core slurry, thereby lightening the weight of the wallboard. The composition and method provide wallboards having lighter weights compared to standard wallboard, increased core strength, and increased paper-to-core bonding.</p> |
