THE STUDY ON FIBER FORM AND CHEMICAL COMPOSITION OF SALIX BARK AND ITS VARIATION
Wood-based panel made of Salix contains certain amount of bark,so we study on the varies of fiber form and chemical composition of Salix bark to find out how Salix bark influence the wood-based panel..The result shows that:1) Salix bark fiber is middle length,and width and cell wall is small,the ratio of length to width is larger than xylem of Salix,the form of Salix fiber mainly influenced by the times of lops.2) Except acid-insoluble lignin,other chemical composition in bark is higher than xylem,and was higher for first time of lop.
