| Zusammenfassung: | A desulfurized gypsum hollow wall slab is produced from desulfurized gypsum powder after being calcinated, fibers and lightweight materials as raw materials and they are mixed uniformly and then the water is poured into them to be stirred into the slurries. A forming die is brought in and a die core tube is extracted after the slurry is solidified initially. The desulfurization is executed after the slurry is solidified and the desulfurized gypsum hollow wall slab. The desulfurized gypsum hollow wall slab of the utility model is provided with a row of circular via holes which can reduce the self weight and a groove which is convenient for installation of construction in the side direction. |
