| Abstract:A poplar bleached chemi-thermo-mechanical （BCTMP） pulp line was updated， which strengthened the mechanical treatment of the prepreg section and the penetration and diffusion of liquid medicine. The updated line was operated stably with the refining energy consumption reduced by 21.42%， and the shive content reduced from 0.10%~0.18% to 0.02%~0.08%， physical strength of pulp improved accordingly. It provided an effective solution to solve the common problems of most domestic chemical mechanical pulp production lines due to the change of raw materials. |
