Effect of Different Sub-Fractions P-RC APMP Fines on Co-Flocculation Process of Fines-Calcium Carbonate
Poplar P-RC APMP was chosen as raw materials for fines generation and collecting, and then the P-RC APMP fines and calcium carbonate were co-flocculated before they were added into fiber fraction to make fine paper. Effect of different sub-fractions P-RC APMP fines and dosage of fines to make fine paper were studied. The result showed that, with the increasing of different sub-fractions fines dosage, the whiteness of paper increased first then decreased. For 200-mesh fines, 300-mesh fines, 400-mesh fines, the highest whiteness are obtained at 10%, 15%, 10% dosage respectively. Adding fines has positive effect on strength properties of paper. With the increasing of fines dosage, the strength properties of paper increased. Besides, the order of paper whiteness and strength is 400-mesh >300-mesh >200-mesh when using the dosage is same.
