PAPER MAKING METHOD USING A NOVEL RETENTION SYSTEM COMPRISING A PRECIPITATED SILICA AND A CATIONIC POLYMER |
摘要 |
The invention concerns a novel method for making paper based on cellulose fibre in sheet form, wherein a novel retention system comprising a suspension of precipitated silica and a cationic polymer is used for improving in particular the retention of the incorporated mineral fillers. The invention also concerns a method for making paper using a retention system which substantially improves draining. More precisely, the invention concerns the use of a precipitated silica and a cationic polymer comprising a cationic guar gum and/or a cationic starch. |
