Study on the Properties of Bleached Chemi-mechanical Pulps from Poplar Wood Processing Residues as Furnishes for Offset Paper
Properties of bleached chemi-mechanical pulp from poplar wood processing residues and properties of offset paper made from this pulp were investigated. Results showed that, at the chemical dosages of 6.0％ hydrogen peroxide combined with 5.0％ sodium hydroxide against to oven-dry chip mass for impregnation, the brightness of pulp could be reached up to 83％ ISO, and at the freeness level of 100 mLCSF, the tensile index of pulp could be up to 43N.m/g. Offset paper products were manufactured using 80-90％ of this pulp and 20-10％ of SBKP, the quality indexes could be reached up to the demand of B grade that confined in the Light Industry Standard QB/T1012-1991.
