Production of P-RC APMP with mixed eucalyptus (60%~90%) and bamboo (10%~40%) as raw materials, including the production technology, equipment operation and characteristics of finished pulp was introduced. The pulp with 68%~78% ISO brightness, 320~450 ml CSF freeness and high bulk of 3.3~4.0 cm3/g was produced by using one stage pre-impregnation, two stages refining and two stages bleaching. The pulp is suitable to use in the grades such as copy paper, white cardboard, writing paper, electrostatic copy paper and offset paper and so on.

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 cm3/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%.
