蒸氣前處理가 木材內部水分擴散에 미치는 效果

Presteaming Effect on Moisture Diffusion in Wood

One - inch thick keruing and radiata pine specimens were steamed at 120 ° C prior to drying to determine the effect of steaming on moisture diffusion in wood. Drying rate data, which were collected at four temperature levels, were used to calculate diffusion coefficients and activation energies. The diffusion coefficients of presteamed keruing were 1.4 to 2.0 times bigger than those of the untreated. while the diffusion coefficients of steamed radiata pine were about the same as those of the untreated. Presteaming decreased the activation energies of radiate pine. but unexpectedly increased those of keruing.
