文摘内容 The technology parameters of P-RC APMP processof the triploid of populus tomentosa and thecomparison of P-RC APMP with one and two stageofpretreatment were investigated in this paper. Theresults showed that in the chemical pretreatment thecharge of NaOH and H202 were the main factors thataffected the pulp qualities. The charge of NaOH,especially in the first stage of chemical pretreatment,was related to pulp strength. The charge of H202contributed much to brightness of the resultant pulp.In addition, the ratio of NaOH to H202 and thedistribution of chemicals in the first and second stageof impregnation also affected the pulp qualities. Thecomparison of one-stage P-RC APMP pulp andtwo-stage P-RC APMP pulp illustrated that thetwo-stage pulp had better brightness and breakinglength, lower light scatting coefficient and opacity。
