摘要： This invention provides low dust low density gypsum wallboard products having high total core void volumes, corresponding to low densities in the range of about 10 to 30 pcf. The wallboards have a set gypsum core formed between two substantially parallel cover sheets, the set gypsum core preferably having a total void volume from about 80% to about 92%, and made from a slurry including stucco, pregelatinized starch, and a naphthalenesulfonate dispersant. The combination of the pregelatinized starch and the naphthalenesulfonate dispersant also provides a glue-like effect in binding the set gypsum crystals together. The wallboard formulation, along with small air bubble voids (and water voids) provides dust control during cutting, sawing, routing, snapping, nailing or screwing down, or drilling of the gypsum-containing products. This invention also provides a method of making the low dust low density gypsum products including the introduction of soap foam in an amount sufficient to form a total void volume, including air voids, preferably from about 80% to about 92% in the set gypsum core, corresponding to a set gypsum core density from about 10 pcf to about 30 pcf. The wallboards produced by the method generate significantly less dust during working.
摘要翻译：本发明提供了具有高的总核心空隙体积的低灰尘低密度石膏墙板产品，对应于在约10至30pff范围内的低密度。墙板具有形成在两个基本上平行的覆盖片之间的一组石膏芯，该组石膏芯优选具有约80％至约92％的总空隙体积，并且由包含灰泥，预胶化淀粉和萘磺酸盐分散剂的浆料制成。预胶化淀粉和萘磺酸盐分散剂的组合也提供了将凝固的石膏晶体结合在一起的胶状样效果。墙板配方以及小的气泡空隙（和水空隙）在切割，锯切，布线，咬合，打钉或拧紧或钻石的石膏产品中提供灰尘控制。本发明还提供了一种制造低灰尘低密度石膏产品的方法，包括引入肥皂泡沫，其量足以形成总空隙体积，包括空气孔隙，优选约80％至约92％的固体石膏芯，对应于约10 pcf至约30 pcf的凝固石膏芯密度。该方法生产的墙板在加工过程中产生的灰尘少得多。

摘要： An improved water resistant gypsum board is made by adding an aqueous wax emulsion containing a cationic surfactant to an aqueous slurry containing calcium sulfate and host particles at a slurry temperature which maintains calcium sulfate hemihydrate crystals. The wax emulsion is stable at the temperature of slurry which maintains the calcium sulfate hemihydrate. The slurry is then dewatered and rehydrated to form a gypsum board and dried at a temperature to melt the wax.

摘要： An improved method and apparatus for imparting a smooth surface to gypsum fiber panels. The method involves imparting energy to the surface of a slurry as the slurry is dewatered just prior to rehydration. The apparatus used to impart the energy is a water spray including a source of pressurized water such as a pump, a distribution manifold and a plurality of nozzles to direct the water spray at the surface of the slurry. In operation, the water spray is directed against the surface of the slurry. The flow disrupts the slurry to a fraction of its total depth, thus dispersing clumps or flocs of commingled crystals and fibers in the depth that would give the surface of the finished panel a rough surface if they were allowed to remain.
