| titleOfInvention | ACOUSTIC PANEL WITH LESS POWDER. |
| abstract | An acoustic layer includes an acoustic layer that has an interconnecting matrix of calcium sulfate dihydrate, polyethylene glycol and one of the group consisting of fibers, a light aggregate and mixtures thereof. The acoustic layer has gaps in the interconnection matrix that are configured to absorb sound. Polyethylene glycol is chosen to agglomerate powders at the temperatures generated by friction when the panel is cut. One method of making the acoustic panels includes making a slurry comprising hemidrated calcium sulfate, polyethylene glycol, water and at least one of the group consisting of a light aggregate, fibers and combinations thereof. Foam is added to the slurry, preferably at the discharge of the mixer. A continuous tape of acoustic layer material is formed from the grout. Acoustic panels are formed by cutting the tape into individual panels. Finally, partially hydrated hemihydrate calcium sulfate is allowed to cure completely. |
