（3）Needlebush pulpboard is discongested with hydrabrusher, the treatment fluid heat-insulation soaking 3- for being then 85-95 DEG C with temperature
4 it is small when, obtain impregnate material it is spare；
（4）The abrasive for being equivalent to its weight 3-6% is added in above-mentioned spare immersion material, is beaten with PFI fiberizers.
As further improvement of these options, the main component of the persimmon leaf extract is natural Victoria C, rutin,
Choline, glycosides displayed；The Conyza japonica extract is the extract of Conyza japonica aerial part, and main component is rigidness formic acid, effectively
The content of ingredient is 1%；The persimmon leaf extract and Conyza japonica extract Jun Youxianchang high mountains bio tech ltd provide.
As further improvement of these options, the grain size of the nano-sized carbon is 400-800nm；The nano-calcium carbonate
Grain size be 400-2000nm；The grain size of the Nanometer Copper is 20-100nm.
As further improvement of these options, the step（3）With 200-400 revs/min of rotating speed in soaking process
Clock stirs.
As further improvement of these options, the step（4）It is middle to control beating degree as 30 ° of SR, control slurry trip
It is 340-360mL from degree.
The present invention has the following advantages compared with prior art：By treatment fluid needlebush pulpboard is discongested in the present invention expect into
Row high temperature immersion treatment can make fiber profit rise, generate fiber fines or fibrous refinement, destroy fibre structure, and treatment fluid has
Fibrous inside can be entered by imitating ingredient, and fibrous inside is made to form amorphous region, weakens the combination of fiber quality inspection, then coordinates grinding again
The use of material, can be further fiber surface activation and relaxation, under mechanicals efforts, fiber can easier cut off and
Wire-dividing broom purification contributes to the raising of needlebush beating degree.
