摘要： The present invention relates to a silica-based sol having a concentration of soluble silica of less than about 1000 mg SiO2/l, conductivity of at least about 2.0 mS/cm and S-value below about 50%. The invention further relates to a method of producing a silica-based sol comprising subjecting an aqueous alkali metal silicate solution to electrodialysis to form an electrodialyzed sol, and acidifying the electrodialyzed sol to form an acidified sol having a pH in the range of from about 5.0 to about 10. The invention further relates to silica-based sol obtainable by the process and to the use of the silica-based sol as a flocculating agent. The invention further relates to a process for producing paper which comprises providing an aqueous suspension comprising cellulosic fibers, adding to the suspension one or more drainage and retention aids comprising a silica-based sol according to the invention, and dewatering the obtained suspension to provide a sheet or web of paper.
摘要翻译：本发明涉及二氧化硅基溶胶，其溶解二氧化硅的浓度小于约1000mg SiO 2 / l，电导率为至少约2.0mS / cm，S值低于约50％。本发明还涉及二氧化硅系溶胶的制造方法，其特征在于，使碱金属硅酸盐水溶液进行电渗析，形成电渗析溶胶，酸化所述电渗析溶胶，形成pH为约5.0的酸化溶胶本发明还涉及通过该方法获得的二氧化硅基溶胶，以及二氧化硅基溶胶作为絮凝剂的用途。本发明还涉及一种用于生产纸的方法，其包括提供包含纤维素纤维的水性悬浮液，向悬浮液中加入一种或多种包含根据本发明的基于二氧化硅的溶胶的引流和助留助剂，并将获得的悬浮液脱水以提供纸张或纸张。
