ABSTRACT

To improve the self-bonding reactivity, Eucalyptus wood fibers were pretreated, processed and analyzed. The results showed that the bio-boards was 1.40 MPa and 1.16 MPa by pretreatment in 0.3% and 1.5% Na2SiO4 solution, respectively. FT-IR and 13C-NMR spectra showed that the chemical structure and reactivity of Eucalyptus wood fibers had different changes after pretreated in sodium silicate solution. It suggested that cellulose, hemicellulose and lignin participated in united chemical reaction and let the pretreated fiber be self-bonded and resistance to water.
