GYPSUM WALLBOARD AND METHOD OF MAKING SAME |
| 摘要 |
Compositions for gypsum board are disclosed, comprising a mixture of a gypsum slurry and a pre-generated foam and a coalescing agent. The coalescing agent comprises one or more coalescing agents that are added to the composition singly, separately or in combination to change the size and distribution of the air bubbles in the foamed gypsum slurry. The resulting gypsum cores have increased nail pull resistance and an improved facer/gypsum core bond. |

1. A foamed gypsum slurry composition, comprising:
stucco; gauging water; a foam comprising foaming water, a foaming agent and air; a first coalescing agent having a first cloud point temperature; and a second coalescing agent having a second cloud point temperature that is different from the first cloud point temperature; wherein the foamed gypsum slurry composition has a mix temperature, and the first and second coalescing agents have a blended cloud point temperature that is lower than the mix temperature. |
