Abstract: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. |
