三倍体毛白杨P-RC APMP二段低浓磨浆初探

Study on the Low Consistency Refining at the Second Stage of P- RC APMP with the Triploid of Populus Tomentosa

本文就三倍体毛白杨P-RC APMP二段低浓磨浆对浆料光学性能和强度性能的影响进行了初步研究,研究结果表明,二段低浓磨浆时所得浆料与高浓磨浆相比具有较少均纤维碎片和较高的光散射系数、相近的不透明度及抗张强度和稍低的撕裂指数。

Low consistency refining at the second stage of P-RC APMP with the triploid of populus tomentosa was studied in this paper. Compared to high consistency refining, low consistency refining at the second stage was more efficient in reducing the shives content, getting a high light scattering coefficient, and producing a pulp with similar tensile, but lower tear index.
