    摘要: Silicas that provide improved abrasive action when incorporated in dentifrice compositions can be prepared by dehydrating a silica hydrogel to a low water content and then reintroducing water to gel. The silica hydrogel is prepared by neutralizing a sodium silicate with an acid. This hydrogel is dried by any convenient method so that the gel contains about 15% water or less. This dried gel is rehydrated to about 30% or more. The rehydrated gel provides improved abrasion values over the prior art xerogels and hydrogels.

    摘要: Inorganic chill-proofing and other agents that are used to process stable beer often contain metals such as iron and copper that are soluble in beer or other beverages. A small addition of magnesium silicate added to said chill-proofing agents, particularly silica hydrogel, substantially averts metal contamination in the beer.

    摘要: Silane-Zeolite composites are incorporated into phosphate free detergents as builders. The use of such composites allows compositional improvements and results in certain process advantages when compared to detergents utilizing plain zeolites as phosphate replacements. Hydrated zeolites which have been treated with functionally hydrophilic silanes do not agglomerate during incorporation into detergents. In addition, use of the silane-zeolite composite allows use of increased amounts of both the zeolite and silicate solids as builders in detergents.

    摘要: Porous granules that contain separate particles of alkali metal silicate and zeolite are stable and are efficient ion exchangers in aqueous effluents and/or solutions. Said granules are heated to provide the stability required so that even though some silicate may dissolve when the granules are exposed to water, the zeolite does not disperse throughout the water.
