Abstract:It is a difficult job to balance the strength property and bulk of the paper using chemi-mechanical pulp as furnish. The effect of the different ratios of the P-RC APMP pulps with different freeness on paper property was studied in this paper. The results indicated that the mixed pulp containing 14 parts of the filler pulp with 60 mL CSF and 100 parts of the backbone pulp with 600 mL CSF can make the paper with reasonably good strength and balk properties. Compared to the paper made of filler pulp with 480 mL CSF, the bulk improves by 14% and tensile and internal bonding strength increase respectively.
