【Abstract】 Study was made on APMP of the Zhonglin poplar-46 which led to the result that the whiteness improves constantly with theconstant increase of H2O2 quantity in the second stage of pretreatment. When H2O2 quantity is 4%、6%、8% respectively, the whiteness is47%、51%、54% of the SBD respectively; when the bleaching rate quantity is 5%, 6%, 3%+3% respectively, the greatest whiteness isgained with 3%+3%; when H2O2 quantity is used in 4% original pulp to make newsprint, the proportion is 85% of APMP and 15% ofbleached softwood; when H2O2 quantity is used in 8% original pulp to make coated paper and lower weight coated paper, the proportion is45% to 55% and 50% and 50% respectively. All their physical indexes meet the specifications of the national quality standard.更多还原
