Blown mineral wool fibers are introduced into slurries (such as gypsum board core formulations and steel column fireproofing plaster formulations) by first blending and coating the blown mineral wool with a powdered calcium sulfate to produce a light, open nodulated effect. When mixed into aqueous calcined gypsum slurries, the nodules open up, thoroughly dispersing the mineral wool-calcium sulfate blend in the aqueous slurry and contributing fire resistant properties to the set gypsum product. |
