Study on Structural Plywood Production Technology from Eucalyptus/poplar

Abstract:

With the rapid development of wooden structure buildings in China, the demand for structural plywood enlarges significantly. Eucalyptus and poplar plantation is a very wide area of growth in china, therefore, there is practical significance to use eucalyptus and poplar plantation to produce wooden structural plywood. This study uses orthogonal test on pressing temperature, pressing time, pressing pressure, veneer glue spread - four factors influence the bond strength of structural plywood from Eucalyptus/poplar, and has obtained the superior technology. The results show that hot pressing temperature, pressing time, pressing pressure, veneer glue spread –four factors affect the bond strength of the structure plywood significantly, but the difference among the three veneer glue spread levels is not significantly. The better production technology is hot pressing temperature 135 °C, pressing time 24 min, pressing pressure 1.2 Mpa, veneer glue spread 320 g/m2.
