摘要： Sodium alumino-silicates are produced by silicate/clay reactions under hydrothermal conditions with increased solids during processing while still producing structural materials characterized by low oil absorption values, high total pore volume and increased differential pore volumes. The products are useful as coating pigments for paper and paperboard, paper fillers, paint pigments and as reinforcing pigments for rubber.

摘要： Pigments for use in paper are comprised of structured aggregate clays which are reaction products of kaolin clays and colloidal silicas. Silica modified clays of low treatment level can under certain high-shear mixing conditions be attritioned back to their starting clay particle size consequently yielding silica coated clay particles that provide unique properties. Also provided are structured aggregate clay products produced by the reaction of kaolin clay, colloidal silicas and spacer particles such as titanium dioxide, which products have improved porosity and light scattering characteristics. Also provided are clay slurry products which comprise mixtures of the reaction product of kaolin clay and colloidal silica, and optionally titanium dioxide, blended with other clay products.

摘要： Processes for making high quality PCC compositions, and the resulting PCC products thereof. A precipitated calcium carbonate (PCC) composition is prepared by a process comprising the step of wet media mill grinding an aqueous slurry of PCC made by carbonation of lime milk, with the grinding being done at a low solids content in a plurality of separate grinding stages, which can done while essentially free of the presence of organic dispersant. After the multi-stage wet grinding step, the ground PCC slurry is partially dewatered in the presence of an organic dispersant in a solid bowl centrifuge. Then, the partially dewatered PCC slurry is subjected, in the presence of an organic dispersant, to fluid shearing forces created in a rotor/stator type mixer. While these three steps are advantageously used together within a single PCC process flow for optimal effect, the individual steps also can be incorporated singly or in lesser combinations thereof into different PCC manufacturing schemes to beneficial effect. The resulting PCC compositions are endowed with reduced high-shear viscosity in aqueous slurry form at high solids content and contain PCC particles of narrower particle size distribution. PCC slurries are provided that are particularly well-suited for paper coatings applications including medium and low coating weight, woodfree paper coatings, although it has wider applicability and is by no means limited thereto. As another aspect, the additional cost otherwise associated with the use of evaporative-based dehydration procedures to increase the PCC solids content in a PCC slurry or associated with the adding of dry CaCO3 pigment to build slurry solids can be reduced or even eliminated by a facile made in a decanting operation within the inventive process flow.
摘要翻译：制备高质量PCC组合物的方法及其所得的PCC产品。沉淀碳酸钙（PCC）组合物通过包括以下步骤的方法制备，所述方法包括湿法研磨研磨由石灰乳碳酸化制备的PCC的含水浆料的步骤，其中在多个分开的研磨阶段以低固含量进行研磨，其可以在基本上不含有机分散剂的情况下完成。在多阶段湿法研磨步骤之后，将研磨的PCC浆料在有机分散剂存在下在固体碗式离心机中部分脱水。然后，将部分脱水的PCC浆料在有机分散剂存在下进行转子/定子式混合机中产生的流体剪切力。尽管这三个步骤有利地在单个PCC工艺流程中一起使用以获得最佳效果，但是各个步骤也可以单独地或以较小的组合并入不同的PCC制造方案中以产生有益的作用。得到的PCC组合物以高固体含量赋予水性浆料形式的降低的高剪切粘度，并且含有较窄粒度分布的PCC颗粒。提供了PCC浆料，其特别适用于包括中等和低涂层重量的无纸纸涂料的纸张涂料应用，尽管它具有更广泛的适用性，并不限于此。另一方面，与使用基于蒸发的脱水方法相关联的增加PCC浆料中的PCC固体含量或与添加干燥的CaCO 3颜料相关以构建浆料固体的附加成本可以通过简便的方式减少甚至消除在本发明工艺流程内的倾析操作中制成。

摘要： A device for dispensing solid into a liquid medium. The device utilizes a funnel with a vortical stream therein for feeding solids into a reaction zone. A portion of the contents of the reaction zone are recycled to supply the fluid for the vortical stream. The device finds particular use in dispersing dry particulate blends of isocyanuric acid and trichloroisocyanuric acid into a reaction slurry.

摘要： A continuous process is disclosed for the production of monoalkali metal cyanurates. In the process, cyanuric acid and an aqueous solution of the alkali metal hydroxide are continuously reacted in a first reactor to produce a first slurry comprised of cyanuric acid and a monoalkali metal cyanurate. This first slurry is conveyed to a second reactor to further react the cyanuric acid with the alkali metal hydroxide to produce a second slurry comprised of the monalkali metal cyanurate.The novel process produces slurries of monoalkali metal cyanurate which are consistent both with respect to chemical composition and solids content while reducing equipment and operating costs.
