摘要： The instant invention relates to a process for the preparation of an aqueous suspension of anionic colloidal silica having a neutral pH which is stable over time and comprises individualized particles of colloidal silica which are not bound to one another by siloxane bonds. The instant suspensions show high storage stability and are particularly useful for the clarification of beer, for the preparation of cosmetic formulations, for the production of ink for printers, for paints and for anticorrosive treatments.

摘要： There provides an organosol of silica, wherein alkaline earth metal ions are bonded on surface of colloidal silica particles. The silica sol has a low solid acidity of silica, thus, in case where it is used in a mixture with a resin and the like, it can inhibit change of properties or decomposition, etc. of the resin, compared with silica sols that no alkaline earth metal is bonded to the surface of the particles. Further, the silica sol can be used as hard coat films for forming the surface of resin molded forms such as lenses, bottles, films or plates, or micro-fillers for thin films, resin internal agents, and the like.

摘要： Silica sols which have a large alkali excess, i.e. a low molar ratio SiO.sub.2 to M.sub.2 O, and which contain silica particles with a high specific surface area. The silica sols can be prepared through acidification of a water glass solution and subsequent alkalization of the acid sol to the molar ratio in question. The sols are particularly suitable for use as additives, in combination with cationic polymers, in papermaking.

摘要： Silica sols are placed in contact with a strong acid cation exchange resin. The sols are then aged out of contact with the cation exchange resin for at least about 4 hours at a temperature of from about 34*F. to about the boiling point of the sols, and again contacted with a cation exchange resin. The process requires placing the sols at least twice in contact with a cation exchange resin with an aging step between each treatment, and also requires that the sols be placed at least once in contact with an anion exchange resin. The formed sols have excellent stability characteristics even at high SiO2 concentrations.
摘要翻译：将二氧化硅溶胶与强酸性阳离子交换树脂接触。然后将溶胶在约34°F至约沸点的沸点下与阳离子交换树脂接触老化至少约4小时，并再次与阳离子交换树脂接触。该方法需要使溶胶至少两次与阳离子交换树脂接触，在每次处理之间具有老化步骤，并且还要求将溶胶放置至少一次与阴离子交换树脂接触。形成的溶胶即使在高SiO 2浓度下也具有优异的稳定性。
