PROCESS FOR PRODUCTION OF PAPER, CARDBOARD OR SIMILAR |
| abstract |
The present invention relates to an improved process for producing paper or cardboard. The process comprises providing a suspension of cellulose fibers which comprises recycled fibrous material and which has a conductivity of at least 1.5 mS/cm; and adding a glyoxalated copolymer of acrylamide and cationic monomers and inorganic silicon microparticles to the fiber suspension, either sequentially or simultaneously. The advantages include greater process productivity and paper strength. |
