摘　　要：This paper mainly discussed the heat transmission rate and physical-mechanical properties of particleboard (PB) and middle density fiberboard (MDF) with different forming methods. In this experiment, both poplar and wheat-straw with different ratios and different shape forms were used as furnishes; UF and MDI were added to the poplar furnish and wheat-straw one, respectively. The experiment results showed that the layer-forming boards were superior to the mixture-forming boards. Under the given experimental conditions, the poplar to wheat straw ratio has no obvious influence on the mechanical properties, but has significant influence on the thickness swell (TS) of PB and MDF.This paper mainly discussed the heat transmission rate and physical-mechanical properties of particleboard (PB) and middle density fiberboard (MDF) with different forming methods.
