蒸球预处理动态挤压法生产化机浆

Dynamic extruding for the production of CMP after pretreatment with the spherical digester

东北阔叶材经蒸球化学预处理后,采用无刀式磨浆设备动态挤压磨解,当得率在74.5%～84.4%时,用作底浆,可生产A级箱纸板。动态挤压磨浆的特殊机理,使纤维长度得到充分保留;纤维细胞初生壁在动态挤压下局部剥落,纤维变得柔软;动态挤压的揉搓作用,使纤维变形、分丝;浆料易于打浆,成纸强度高。

After chemically pretreated,Northeast hardwood was extruded and refined by none-knife refining equipment.When theyield is between 74.5% and 84.4%,it can be used as the base pulp for producing standard A paper board.The special dynamicextruding and refining mechanism fully retain the fiber length;the fiber cell wall is partly peeled under the dynamic extruding,and thefiber becomes soft.The dynamic rubbing makes fiber transformed,disparted.It is easy to beat, then high strength paper can be made.
