桉木与竹子混合生产P-RC APMP

摘要

Production of P-RC APMP with railed 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 pie-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.%介绍了以桉木(60%～90%)和竹子(10%～40%)为原料,生产P-RC APMP的生产实践.该生产线采用一段预浸、两段磨浆和两段漂白,生产出了白度68%～78%,游离度(CSF)320～450 mL,松厚度3.3～4.0 cm3/g的按竹混合化机浆,主要用于配抄轻型纸、白卡纸、书写纸、静电复印纸和双胶纸等.
