Study on the Interface Character of Drying Binderless Fiberboard
The ways of chemical component analysis,chemical analysis photoelectron energy spectrum (ESCA) analysis and X ray diffraction were used to research and analyze the variation law of material (wood) chemical component,functional groups and cellulose crystallinity in the process of making board.The results showed that: (1) The maximum contents of holocellulose and pentosan were wood,in the next place were fiberboard,and the minimum one were binderless fiberboard.The maximum contents of a-cellulose were woodfiber,in the next place were wood,and the minimum one were binderless fiberboard.The minimum contents of xylogen were wood,in the next place were woodfiber,and the maximum one were binderless fiberboard.(2) The C1 and C3 functional groups relative contents of woodfiber and binderless fiberboard were higher than wood.The C2 functional groups relative contents of wood were higher than woodfiber and binderless fiberboard.The C4 functional groups relative contents of woodfiber were zero,and the binderless fiberboards were higher than wood.(3)The maximum cellulose relative crystallinity was binderless fiberboard,in the next place was fiberboard,and the minimum one was wood.
