本实验以杨木化机浆与化学浆配抄,测定纤维表面木素含量和纸页的相对结合面积,利用多元线性回归,建立了纸页抗张强度与纤维表面木素含量、纸页相对结合面积和纸页零距抗张强度的回归方程,以及纸页内部结合强度与纤维表面木素含量和纸页相对结合面积的回归方程。研究表明纸页抗张强度与纸页相对结合面积和零距抗张强度正相关,与纤维表面木素含量负相关。纸页内部结合强度受纤维表面木素含量和纸页相对结合面积的影响,相对结合面积对内部结合强度的影响比纤维表面木素含量更为显著。
The experiment with poplar pulp and chemical pulp copy, measuring the fiber surface lignin content and the relative binding area of the paper, the use of multiple linear regression to establish the paper tensile strength and the fiber surface lignin, paper, the relative binding area And the paper zero return tensile strength of the regression equation, as well as the combination of paper and paper fiber surface lignin content and the relative binding area of the paper regression equation. The research shows that the tensile strength of paper is positively correlated with the relative bonding area of paper and zero-span tensile strength, and negatively correlated with the lignin content of fiber surface. The internal bonding strength of the paper is affected by the lignin content on the fiber surface and the relative bonding area of the paper sheet. The relative bonding area has a more significant influence on the internal bonding strength than the lignin content on the fiber surface.
