METHOD OF PREPARING AQUEOUS SUSPENSION FOR MANUFACTURING PAPER (VERSIONS), PAPER |
摘要 |
paper-and-pulp industry. SUBSTANCE: suspension containing polyelectrolyte complex is obtained by preparing aqueous suspension of pulp containing water-soluble cationic polymer and water-soluble anionic polymer which are capable of interacting in aqueous suspension to form polyelectrolyte complex and compound containing multivalent cation having charge at least +3 and forming polyelectrolyte complex. In another embodiment, aqueous suspension of fibrous pulp contains surface-active carboxyl-containing compounds and water-soluble anionic compounds. EFFECT: increased strength of paper, improved sizing quality, friction factor, and water loss. 24 cl, 9 tbl
