    Abstract: Effective use of dispersants in wallboard containing foam results from a method where stucco is mixed with a first dispersant and a first quantity of water to form a gypsum slurry. A soap is blended with a second dispersant and a second quantity of water to make a foam. Subsequently, the foam is combined with the slurry. Choice of different first and second dispersants and their relative amounts allows control of the size distribution of the foam bubbles in the slurry and the resulting voids in the gypsum core. Melamine sulfonate condensate and polycarboxylate dispersants are preferred dispersants.

    Abstract translation: 分散剂在含泡沫的墙板中的有效使用是将灰泥与第一分散剂和第一量的水混合以形成石膏浆料的方法得出的。 将肥皂与第二分散剂和第二量的水混合以制备泡沫。 随后，将泡沫与浆料混合。 选择不同的第一和第二分散剂及其相对量允许控制浆料中的泡沫气泡的尺寸分布和所产生的石膏芯中的空隙。 三聚氰胺磺酸盐缩合物和聚羧酸盐分散剂是优选的分散剂。

    Abstract: An acoustical panel is made by applying a thin, acoustically- transparent coating to an acoustical base mat. A pulp is made from one or more fillers, a fibrous filler, a binder and water. A thickener solution is prepared from a thickener and water. A portion of the pulp and the thickener solution are mixed under high shear conditions to degrade the fibrous filler and form a smooth coating. The coating is applied to and distributed over a base mat and the coated base mat is then cut and dried to form a coated acoustical panel. The panel is free of visible mineral nodules on the surface of the coating. Optionally, the pulp is a portion of a pulp used to make the base mat. Other embodiments include the use of recycled dust or fine particles of the acoustical panel obtained from cutting or shaping the base mat or coated panels.

    Abstract translation: 通过将薄的，声透明的涂层施加到声学基底垫上来制造声学面板。 纸浆由一种或多种填料，纤维填料，粘合剂和水制成。 由增稠剂和水制备增稠剂溶液。 一部分纸浆和增稠剂溶液在高剪切条件下混合以降解纤维填料并形成光滑的涂层。 将涂层施加并分布在基底垫上，然后将涂覆的基底垫切割并干燥以形成涂覆的声学面板。 该面板在涂层表面上没有可见的矿物结节。 任选地，纸浆是用于制造基底垫的纸浆的一部分。 其他实施方案包括使用通过切割或成形基底垫或涂覆板获得的再生粉尘或声学板的细颗粒。
