METHOD FOR LOADING FIBERS CONTAINED IN A PULP SUSPENSION

The present invention serves for loading a pulp suspension (S) with calcium carbonate. Liquid calcium hydroxide as milk of lime ( 7 ) is added during or before the pulp operation ( 1 ) carried out to form the pulp. By introducing gaseous carbon dioxide ( 8 ) into the pulp suspension thus treated, a...

Beschreibung
Zusammenfassung:	The present invention serves for loading a pulp suspension (S) with calcium carbonate. Liquid calcium hydroxide as milk of lime ( 7 ) is added during or before the pulp operation ( 1 ) carried out to form the pulp. By introducing gaseous carbon dioxide ( 8 ) into the pulp suspension thus treated, a chemical reaction is triggered therein, in which the finely divided calcium carbonate is precipitated. The present invention is particularly economic and effective due to the early addition of calcium oxide or calcium hydroxide.
