摘要： Described are high solids aqueous slurries of amorphous precipitated hydrated silica, which slurries are of relatively low viscosity. The slurry typically contains from about 40 to about 60 weight percent of hydrated precipitated high structure silica. The viscosity of the high solids slurry is less than about 1000 centipoises. Processes for producing the aqueous high solids silica slurry are disclosed. In one embodiment, a wet cake of amorphous precipitated hydrated silica is liquified and the liquified wet cake charged to a high intensity mill wherein the silica is wet milled until the median agglomerate particle size of the silica is between about 0.3 and about 3 microns. In a further embodiment, finely-divided dry amorphous precipitated silica is slurried in a dispersion mill to the desired solids level and this slurry charged to a high-intensity mill and wet milled therein until the aforesaid agglomerate particle size range is attained. The resulting high solids slurry can be shipped in bulk with only mild agitation to prevent setting. A dispersant may also be added to the slurry prior to milling to retard settling of the silica.
摘要翻译：描述了无定形沉淀的水合二氧化硅的高固体含水浆料，其中浆料的粘度相对较低。浆料通常含有约40至约60重量％的水合沉淀高结构二氧化硅。高固体浆料的粘度小于约1000厘泊。公开了用于生产含水高固体二氧化硅浆料的方法。在一个实施方案中，将无定形沉淀的水合二氧化硅的湿滤饼液化并将液化的湿滤饼装入高强度研磨机中，其中二氧化硅被湿磨，直到二氧化硅的中值附聚物粒度在约0.3至约3微米之间。在另一个实施方案中，将细碎的干无定形沉淀二氧化硅在分散研磨机中浆化至所需的固体含量，并将该浆料装入高强度研磨机中并在其中湿磨，直到达到上述附聚物粒度范围。所得到的高固体浆料可以散装运输，只需轻微的搅拌即可防止固化。在研磨之前还可以将分散剂加入到浆料中以阻止二氧化硅沉降。

摘要： A continuous integrated process for the production of calcium hypochlorite in which crystals of by-product sodium chloride are more easily separated for the calcium hypochlorite product is described. The process includes: (a) introducing with agitation into a vessel an aqueous slurry of dibasic calcium hypochlorite, sodium hydroxide, and aqueous salt solution saturated with calcium ion and sodium chloride in amounts at least sufficient to substantially dilute the sodium hydroxide; (b) forwarding the resulting aqueous mixture of step (a) to a chlorination zone containing a seed bed of calcium hypochlorite and sodium chloride crystals; (c) introducing chlorine into the chlorination zone, thereby producing an aqueous suspension containing further quantities of calcium hypochlorite crystals and readily separable significantly larger sodium chloride crystals; and (d) removing aqueous suspension containing such calcium hypochlorite and sodium chloride crystals from the chlorination zone to a classification zone. Calcium hypochlorite crystals are maintained in suspension in and removed from the upper portion of the classification zone; while the larger and more dense crystals of sodium chloride settle and are removed from the lower portion of said classification zone.
