摘要： Cationic kaolin clay which is useful as a filler and coating agent in paper and in paints, and as a pitch control agent in paper making processes, is produced by treating kaolin clay with 0.5 to 1.5 wt. % of aluminum chlorohydrate. The cationic clay, when added to an aqueous system containing paper fibers, is attracted to the anionic paper fibers causing coflocculation of pigment and paper fines so as to increase pigment and paper fines retention and, additionally, optical and mechanical properties of the paper. When added to paint, the optical properties and hiding power are improved. When added to a paper furnish containing pitch, the pitch fines are absorbed.

摘要： A high bulking kaolin pigment is provided which exhibits improved opacifying efficiency as a paper filler. The kaolin pigment comprises an uncalcined clay composition consisting essentially of kaolin particles which have not only been treated with an amine, but also upon which aluminum hydroxide has been precipitated, and, of which less than about 20 % by weight have a particle size less than 0.3 microns in equivalent spherical diameter. Further, a method is provided for producing the pigment from a hydrated kaolin clay having a brightness of at least about 89. The selected starting clay is dispersed in water and subjected as a slurry to delamination, defining, surface treatment with an amine and aluminum sulfate, and leaching. The treated kaolin slurry is subsequently rinsed and filtered to produce a filter cake which is redispersed to yield a commercial paper filler.

摘要： A selected kaolin crude or crude fraction is purifed by physical or physical/chemical means, such as froth flotation and/or selective flocculation, to remove discrete particles of TiO2 and in some cases, discrete iron minerals. The pure (or purified clay) must then be agitated in the presence of water with a particulate grinding media such as, for example, sand, alumina or zirconia beads, to increase the 2 micron content of the kaolin. An intermediate ground product that contains a substantial weight percentage of particles finer than 1 micron is generated as a result of grinding. The particles finer than 1 micron in the ground kaolin also include those particles in the previously pure or purified kaolin that were present in the naturally occurring clay. A pulp of the ground clay is then fractionated to remove particles larger than 2 microns, e.g., to remove at least 95 %, preferably at 100 % by weight, of the particles larger than 2 microns, while minimizing the removal of particles finer than 1 micron. The resulting fine particles size fraction is then treated by conventional series of steps, i.e., optional bleaching, drying, pulverization, calcination and repulverization to produce a low abrasion, ultrahigh brightness (typically 96 %) calcined kaolin pigment.
摘要翻译：所选择的高岭土粗油或粗馏分通过物理或物理/化学方法（例如泡沫浮选和/或选择性絮凝）净化，以除去TiO 2的不连续颗粒，并且在一些情况下为离散的铁矿物质。然后必须在水的存在下用颗粒研磨介质例如砂，氧化铝或氧化锆珠搅拌纯（或纯化的粘土），以增加高岭土的2微米含量。作为研磨的结果产生了含有大于1微米的颗粒的重量百分数的中间磨碎产物。研磨高岭土中微粒比1微米的颗粒还包括存在于天然粘土中的先前纯化或纯化的高岭土中的那些颗粒。然后将研磨粘土的纸浆分馏以除去大于2微米的颗粒，例如，除去大于2微米的颗粒的至少95％，优选100重量％，同时最小化除去比1更细的颗粒微米。然后通过常规的一系列步骤，即任选的漂白，干燥，粉碎，煅烧和再造浆处理所得到的细颗粒尺寸级分，以产生低磨损，超高亮度（通常为96％）煅烧高岭土颜料。

摘要： A method for modifying the surface properties of kaolinite or a kindred mineral comprises the step of subjecting the mineral to a water vapour plasma. The modification involves the generation of reactive hydroxyl sites on the surface of the kaolinite. The plasma treatment may be followed by treatment with an appropriate chemical reagent to further modify the surface properties of the mineral.

摘要： Described is a process for separating a mixture of finely divided minerals into constituents thereof. In particular, the invention relates to a procedure for effecting such separation by a novel selective flocculation technique wherein a dispersed aqueous pulp containing the mixture of minerals is preconditioned for selective flocculation with an anionic polymer by addition of both a fatty acid such as oleic acid and source of polyvalent cation such as calcium chloride. The fatty acid and cation of the salt selectively coat the component of the mixture that is subsequently flocculated with the anionic polymer. A polyacrylate salt dispersant is preferably used in the process. The invention is especially adapted to the separation of colored titaniferous impurities from kaolin clay in which case both a white purified kaolin product and a strongly flocculated dun-colored titania/kaolin mixture are recovered and then dispersed producing a material useful as a paper coating pigment.

摘要： Paper coating pigments comprising a product obtained by the controlled mechanical delamination of kaolin particles. The pigments provide improved opacification, brightness, printing properties and gloss compared to conventional delaminated kaolin pigments. The pigment of the invention is particularly useful for coating light weight printed paper and provides a unique combination of high opacity, brightness and gloss not available when using other kaolin pigments. The novel pigment is specifically designed to replace plastic pigments and (or) titanium dioxide in coating formulations while maintaining or improving desired paper properties.
