摘要： A dispersant composition for use in gypsum and/or cementitious compositions that includes, in combination, a polycarboxylate-based superplasticizer and a synergistically effective amount of an aluminum salt. The presence of the aluminum salt, such as aluminum chlorohydrate, improves the performance of the polycarboxylate-based superplasticizer.

摘要： Methods for making a sulfated polyaluminum chloride (PACS) flocculating agent solution, which may be aqueous, include neutralizing an aqueous sulfate-containing aluminum compound with an aqueous base to produce an aluminum hydroxide precipitate dispersed in a liquid, settling the aluminum hydroxide precipitate to create a supernatant liquid, removing an amount of the supernatant liquid to leave a remainder that contributes a selected concentration of sulfate to the PACS, and bringing the precipitate back into solution thereby forming the PACS flocculating agent. Also, methods for making a polyaluminum chloride (PAC) flocculating agent solution are disclosed that include neutralizing an aqueous chloride-containing aluminum compound with an aqueous base to produce an aluminum hydroxide precipitate dispersed in a liquid, settling the aluminum hydroxide precipitate to create a supernatant liquid, optionally, removing an amount of the supernatant liquid, and bringing the precipitate back into solution thereby forming the PAC flocculating agent.

摘要： The present invention provides a dispersant and foaming agent combination that is useful in the production of gypsum wallboard and other aqueous cementitious products, a method of forming a gypsum wallboard and a gypsum wallboard. The dispersant in the combination according to the invention is a naphthalene sulfonate-aldehyde condensate alkali salt polymer having a weight average molecular weight of from about 17,000 to about 47,000. The alkali is preferably an alkali metal and/or an alkaline earth metal. The aldehyde is preferably formaldehyde. The foaming agent used in the combination according to the invention is a soap, preferably an alkali salt of an alkyl ether sulfate and/or an alkyl sulfate. The combination of a high molecular weight dispersant and a foaming agent produces a gypsum wallboard core effect that more efficiently entrains air (i.e., creates void space), thereby lowering overall board weight without detrimentally affecting strength. A gypsum wallboard formed using the dispersant and foaming agent combination according to the invention exhibits a higher nail pull value than gypsum wallboard formed using a conventional dispersant and a foaming agent at the same solids loading ratio.
摘要翻译：本发明提供了可用于生产石膏墙板和其他水性水泥质产品的分散剂和发泡剂组合，形成石膏墙板和石膏墙板的方法。根据本发明的组合中的分散剂是重均分子量为约17,000至约47,000的萘磺酸 - 醛缩合物碱金属盐聚合物。碱优选为碱金属和/或碱土金属。醛优选为甲醛。根据本发明的组合中使用的发泡剂是皂，优选烷基醚硫酸盐和/或烷基硫酸盐的碱金属盐。高分子量分散剂和发泡剂的组合产生更有效地夹带空气（即，产生空隙空间）的石膏墙板芯效应，从而降低整体板重量而不会不利地影响强度。使用根据本发明的分散剂和发泡剂组合形成的石膏墙板与使用常规分散剂和发泡剂以相同的固体负载比形成的石膏墙板相比表现出较高的拔牙力。

摘要： The present invention provides supported peroxides, and a method of forming supported peroxides. Supported peroxides according to the invention are solid particles that include an organic peroxide, a metallic soap, and a polymer. In accordance with the method of the invention, supported peroxides are preferably formed by dispersing a mixture that includes at least one peroxide and at least one C4 to C30 carboxylic acid into an aqueous solution that includes a compound that is capable of reacting with the C4 to C30 carboxylic acid to form a water soluble soap. Dispersing the mixture into the aqueous solution results in the formation of an emulsion. Polymer is then added to the emulsion, and forms a polymer suspension. A polyvalent metal compound that is capable of reacting with the water soluble soap to form a water insoluble metallic soap is then added to the polymer suspension, which converts the water soluble soap into a water insoluble metallic soap that precipitates from the suspension. The organic peroxide and the polymer are entrained within the precipitate.
