摘要: Novel and innovative PCC pigments, having a reduced production cost, able to be used in paper coating formulations manufacture coated high-quality matt papers, particular for inkjet applications. Process the preparation of same, using flow rate carbon dioxide-containing gas carbonation step, which produces stable, porous, agglomerates featuring unique properties structure, this step being followed by an upconcentration increase solids content.
