摘要： An additive for accelerating the setting reaction of gypsum products is disclosed. It comprises a gypsum accelerator combined with a bisulfate salt. The gypsum accelerator is calcium sulfate dihydrate. The accelerator may optionally be ground with a sugar, a starch and/or boric acid. A process utilizing this additive combination is also disclosed. The bisulfate salt is most advantageously prewet with a portion of the calcium sulfate hemihydrate feed before being combined with the gypsum accelerator, water and the remaining portion of the calcium sulfate hemihydrate feed in the main mixer.

摘要： A set accelerator for at least one of accelerating the hydration rate and reducing the set time of an aqueous slurry of calcium sulfate hemihydrate is described. The set accelerator consists of a mixture of ground calcium sulfate dihydrate and zinc sulfate material. Aluminum sulfate material is an optional component of the set accelerator. The set accelerator is particularly useful in accelerating the hydration rates of sprayable plasters. A fluid form of the set accelerator may be made by suspending the solids in water. The fluid form is advantageously used in ready mixed setting type joint compounds.

摘要： An acoustical panel includes an acoustical layer has an interlocking matrix of calcium sulfate dihydrate, polyethylene glycol and at least one of the group fibers, a lightweight aggregate and mixtures thereof. The acoustical layer has voids in the interlocking matrix that are configured to absorb sound. The polyethylene glycol is selected to agglomerate dust at temperatures generated by friction when panel is cut.A method of making the acoustical panel includes making a slurry comprising calcium sulfate hemihydrate, polyethylene glycol, water and at least one of the group consisting of a lightweight aggregate, fibers and combinations thereof. Foam is added to the slurry, preferably at the mixer discharge. A continuous strip of acoustical layer material is formed from the slurry. The acoustical panels are formed by cutting the strip into individual panels. Finally, the partially hydrated calcium sulfate hemihydrate is allowed to fully set.
