Abstract:

Using the residues from wood conversion of Acacia and Eucalyptus species as material, the molded decorative particleboard products were manufactured by two-stage process and the relationship between process parameters and properties of products were studied in this paper. The result showed that two-stage process was practical to pre-press particleboard mat then to hot-press in mold to produce tridimensional decorative particleboard. According to designed parameters, properties of Acacia products all exceeded national standard. In the study of relationship between process parameters and properties of products, it was remarkable that aiming density influenced on properties of surface, internal bond strength(IB) and bending strength and so on. Hot-pressing temperature and time parameters had visible affected on thickness expansion rate of water absorbing(TS) of the panels. As application of glue increased, all physical-mechanical properties increased, especially for TS.
