采用不同比边缘负荷,比较研究了3种混合木浆磨浆性能。结果表明:~#3纸浆容易打浆,~#1纸浆次之,~#2纸浆最难打浆;当纸浆打浆度低于60°SR时,~#2纸浆、~#3纸浆的抗张强度较大,当纸浆打浆度低于60°SR时,~#1纸浆、~#3纸浆的抗张强度更具优势;~#2纸浆成纸松厚度大,~#1纸浆、~#3纸浆的成纸松厚度较差。另外,比边缘负荷较低时,混合木浆磨浆能耗和成纸性能更好。
Using different ratio of edge load, comparative study of the three kinds of mixed pulp refining performance. The results show that ~ # 3 pulp is easier to be pulped, ~ # 1 pulp is the second, and pulp # 2 is hardest to beaten. When the pulp beating degree is lower than 60 ° SR, the tensile strength of pulp # 2 and pulp # The tensile strength of # 1 pulp and # 3 pulp is more advantageous when the pulp beating degree is lower than 60 ° SR. The pulp thickness of # 2 pulp is large, and the contents of # 1 pulp and # 3 pulp Into a loose bulk paper. In addition, mixed wood pulp refining energy consumption and paper performance is better than when the edge load is low.
