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。
The northeast broad-leaved wood was pretreated by steam-ball chemistry and was dynamically squeezed and ground with a knife-less refining equipment. When the yield was between 74.5% and 84.4%, it was used as the bottom pulp to produce A-grade cardboard boxes. Dynamic extrusion of the special mechanism of grinding, so that the fiber length is fully retained; fibroblast primary wall under dynamic extrusion of the local exfoliation, the fibers become soft; dynamic extrusion of the rubbing effect, the fiber deformation, sub-silk; slurry easy Beating, paper into high strength.
