Action Mechanism of High-shear Fiber Kneader Treatment on the Aspen BCTMP Fiber Morphology
The fiber morphology of aspen BCTMP treated by the high-shear fiber kneader was investigated in this paper.The main process parameters were measured including: rotational speed of screw,pulp consistency of entrance and exit,pressure and temperature of pulp.The results showed that the main action of high-shear fiber kneader on fibers was promoted the relative displacement of exterior and interior fibers,rather than the cutting fibers.After the treatment by the high-shear fiber kneader under high consistency pulp,the shives could be reduced by 95％.The fiber morphology was obviously different from the control samples.With the exit pressure of high-shear fiber kneader increased,the fiber length,fiber width and fiber coarseness decreased,but the index of curl and kink increased.
