摘　　要：介绍了以速生桉木为原料、工业化生产P-RCAPMP生产线的工艺和设备特点。该生产线采用一段预浸、两段磨浆和两段漂白,生产出了多种白度(主要产78%～84%白度的浆,其中高白浆可稳定达到83%～84%)、游离度(CSF300～500mL)、高松厚度(3.5～4.5cm3/g)的桉木化机浆,主要用于配抄轻型纸、白卡纸、书写纸、静电复印纸、胶版印刷纸和擦手纸等。一段漂的化学品用量:H2O25%～6%,NaOH2.0%～2.6%,Na2SiO33.0%～4.0%,DTPA0.7%～1.0%;二段漂的化学品用量:H2O24.5%～5.5%,NaOH2%～2.5%,Na2SiO33.0%～3.5%,DTPA0.6%～0.8%。这是在我国首次实现的速生桉木P-RCAPMP工业化生产。This paper mainly introduced the process and equipment of the first industrial P-RC APMP production line in the China with raw material of 100% Eucalyptus.The process includes one stage impregnation,two stages refining and two stages bleaching.It can produce mechanical eucalyptus pulps with brightness 78%～84%ISO,Canada standard freeness 300～500 mL,and high bulk 3.5～4.5 cm^3/g.The pulp can be used to produce bulky paper,card board,writing paper,electrostatic copy paper,offset paper,toilet paper and so on.The dosages of chemicals in first bleaching stage were H2O2 5%～6%,NaOH 2.0%～2.6%,Na2SiO3 3.0%～4.0%,DTPA 0.7%～1.0%;The amounts of chemicals of second bleaching stage were H2O2 4.5%～5.5%,NaOH 2.0%～2.5%,Na2SiO3 3.0%～3.5%,DTPA 0.6%～0.8%.
