| description | The present invention relates to a method for providing a pretreated filler composition for use in paper and board manufacturing including the steps of: a) providing a filler comprising precipitated calcium carbonate, said filler being in the form of a slurry comprising no additives; b) providing at least one polymer selected from polyvinylamine or polyacrylic amide, said polymer having a charge density of an absolute value of at most 4 meq/g determined at pH 7; c) combining said at least one polymer of step b) with the filler of step a); d) providing a slurry of nanofibrillar cellulose; e) combining said nanofibrillar cellulose slurry with the formed combination of step c) and forming a pretreated filler composition comprising aggregates. Further it also relates to a pretreated filler composition prepared therefrom, and its use in stocks, paper and paper board.
本发明涉及种用于提供在纸和纸板制造中使用的预处理过的填料组合物的方法，该方法包括以下步骤：a)提供种包含沉淀碳酸钙的填料，所述填料是呈不包含添加剂的淤浆的形式；b)提供至少种选自聚乙烯胺或聚丙烯酰胺的聚合物，所述聚合物具有在pH 7确定的最多4meq/g的绝对值的电荷密度；c)将步骤b)的所述至少 |
