| titleOfInvention | For the manufacture of the method retaining paper with drainage properties and plate with improvement |
| abstract | For the manufacture of the method retaining paper with drainage properties and/or plate with improvement, according to this method, before described paper and/or plate are shaped, at least two kinds of retention agents are added accordingly: a kind of main retention agent in fibrous suspension, corresponding to one (be total to) polymer of cationic charge density higher than 2meq/g, obtained by hoffman degradation reaction; A kind of second retention agent, corresponding to the polymer of anionic charge density higher than a kind of water-soluble of 0.1meq/g or water-swellable; It is characterized in that: this main retention agent introduces in this fibrous suspension with the ratio of 100g/t to 800g/t dry pulp, this second retention agent introduces in this fibrous suspension with the ratio of 50g/t to 800g/t dry pulp and its intrinsic viscosity IV is higher than 3dl/g. |
