发明名称 Fire resistant gypsum board . . . anhydrite
摘要 Increased fire resistant gypsum board core formulations and plaster fireproofing formulations are provided by incorporating calcium sulfate anhydrite into the formulations. Particularly fire resistant effects are achieved with a fibrous form of calcium sulfate anhydrite, and with blends of calcium sulfate anhydrite II in particulate or fibrous form. Optionally, the formulations may contain either small amounts of textile glass fiber, wollastonite or vermiculite.
