Abstract

Papir eller papp fremstilles ved dannelse av en vandig cellulosesuspen- sjon, føring av cellulosesuspensjonen gjennom ett eller flere skjærkraft- trinn, awanning av suspensjonen for å danne et ark og tørking av arket, idet cellulosesuspensjonen som er tørket, omfatter organisk polymermateriale og uorganisk materiale, hvor det organiske materiale er et flokkuleringsmiddel med en molekylvekt over 500 000 og tilsettes til suspensjonen før et av skjærtrin- nene, og hvor det uorganiske materiale omfatter bentonitt som tilsettes suspen- sjonen etter dette skjærtrinn, kjenne- tegnet ved at det organiske, polymere materiale omfatter en anionisk eller ikke-ionisk polymer.
