Abstract

Das Verfahren dient zum Beladen einer Faserstoffsuspension (S) mit Calciumcarbonat. Dazu wird z.B. flüssiges Calciumhydroxid als Kalkmilch (7) bei oder vor der zur Bildung des Faserstoffs durchgeführten Auflösung (1 ) zugegeben. Durch Einbringen von gasförmigem Kohlendioxid (8) in die so behandelte Faserstoffsuspension wird in dieser eine chemische Reaktion ausgelöst, bei der fein verteiltes Calciumcarbonat ausgefällt wird. Das Verfahren ist durch die frühzeitige Zugabe von Calciumoxid oder Calciumhydroxid besonders wirtschaftlich und effektiv.
