| titleOfInvention | Silica-based sol and its manufacture and uses |
| abstract | The present invention relates to a process for preparing an aqueous silica-based sol comprising the steps of: (a) providing a cation exchange resin having at least a portion of ion exchange capacity in hydrogen form; (b) contacting the ion exchange resin with a water soluble alkali metal silicate to form a water soluble slurry; (c) stirring the aqueous slurry so that the pH of the aqueous phase is in the range of 5.0 to 8.0; (d) adjusting the pH of the aqueous solution to be greater than 9.0; And (e) separating the ion exchange resin from the aqueous phase after step (c) or step (d).n n n The present invention also relates to an aqueous silica-based sol obtainable by a method such as paper making, comprising the following steps: (i) providing an aqueous suspension comprising cellulosic fibers; (j) adding to the suspension at least one drainage and retention enhancer comprising an aqueous silica-based sol according to the invention; And (k) dehydrating the obtained suspension to provide a paper sheet or web. |
