    摘要: This method relates to making a joint compound that includes predispersing a dedusting agent in water to make a predispersed dedusting agent. Dry components, including at least one filler, are combined to make a dry mixture. Process water is pumped into a vessel and the predispersed dedusting agent is introduced to the vessel. The dry mixture is then added to the vessel and all components are blended to make a homogeneous product.

    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.

    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.
