摘要： Disclosed are stable, aqueous colloidal silicas having surface area of greater than 700 m2/g and S-values of from 20-50. These colloidal silicas do not require treatment with surface treatment agents such as aluminum to achieve stability. These colloidal silica aquasols can be produced and stored at concentrations of greater than 7 percent by weight SiO2 solids, and even as high as 15 percent by weight solids or higher, and remain stable at room temperature for at least 30 days compared to art-known silica aquasols. These colloidal silica sols demonstrate advantageously improved performance over art-known colloidal silica sols in applications such as in drainage and retention in papermaking processes. Also disclosed are processes for making aqueous colloidal silicas of the invention and the use of such colloidal silicas in papermaking processes.

摘要： A method for the manufacture of paper comprising the steps of: a) forming an aqueous cellulosic papermaking slurry; b) adding an effective coagulating amount of a coagulant and a flocculant to said cellulosic papermaking slurry, wherein said coagulant is prepared by blending i) an effective coagulating amount of an aqueous conditioned colloidal silica sol with an average particle size within the range of from 1 to 150 nm and wherein the aqueous colloidal silica sol is conditioned by contacting said sol with a strong acid cation exchange resin, and ii) an effective coagulating amount of a cationically-charged water-soluble polymeric coagulant; c) draining said cellulosic suspension to form a sheet; and, d) drying said sheet. The components of the invention are blended together so that addition is simultaneous. The colloidal silica is conditioned by passing over a cationic exchange resin prior to addition of cationic polymer. The term conditioned as used herein refers to the act of passing the colloidal silica over a cationic exchange resin.

摘要： The present invention relates to a method for forming a silica-based particle or composite consisting of a silica-based material, an active, with or without a surface modification, and the related composition. The silica-based particle is illustrated by the formula (SiO2)x(OH)yRzSt, whereby R is an active or actives such as an organic or inorganic molecule that includes markers, amines, thiols, epoxies, organosilicones, organosilanes, and water soluble agents and, optionally, a surface modifier, S, which may be either organic, polymeric, or inorganic. Examples of a surface modifying material are inorganic salts of aluminum and boron or organic materials such as organosilanes or low molecular weight polymers. As such, the particle can be used in a variety of applications including any of a variety of high temperature, at acidic, neutral, or basic pH, or pressure environments. The composites have applications as diverse as papermaking, water treatment, chemical tracing, personal care, microbiological control, and delivery of polymers, for example. With regard to papermaking, the particle provides retention and drainage performance while delivering whitener, or OBA, other functional additives and serves an additive tracker.
