Abstract

The invention discloses a quantitative analysis method for the influence degree of papermaking fiber characteristics on the mechanical properties of paper. ; Use Back Propagation Neural Network (BPNN) to establish a statistical model of the relationship between paper fiber properties and paper mechanical properties, and analyze the relationship trend of paper fiber properties on paper mechanical properties one by one; Quantitative analysis of paper fibers based on grey relational analysis The degree of influence of the properties on the mechanical properties of the finished paper. The method is simple and easy to implement, and has the characteristics of simple modeling and analysis process. Aiming at the only qualitative relationship between paper fiber properties and paper mechanical properties, a quantitative analysis method for the relationship between the two is proposed, which reveals the papermaking The quantitative results of the influence of fiber characteristics on the mechanical properties of paper will have an important guiding role in the production and research work of the pulp and paper industry.

Description

technical field [0001] The invention relates to the technical fields of pulping and papermaking, machine learning and statistical analysis, in particular to a quantitative analysis method for the degree of influence of papermaking fiber characteristics on the mechanical properties of papermaking. Background technique [0002] In the field of pulp and paper, the mechanical properties of the finished paper mainly depend on the properties of its raw material, namely the fiber. However, due to the many characteristics of papermaking fibers, there is mutual influence between different characteristics, and the mechanical properties of papermaking are often determined by multiple papermaking fiber characteristics and papermaking processes, so it is difficult to quantitatively analyze the effect of different papermaking fiber characteristics on papermaking. The degree of influence on mechanical properties. [0003] In the current production and research in the field of papermaking,...
