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30pcf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。
