Water Sorption Behaviors of Five Woods above Fiber Saturation Point

摘要

Woods from Korean Larch, Chinese Fir, Aspens, Manchumian, and Fortunes Paulownia were chosen for investigation. Specimens cut from the air-dried woods had a cubic shape with nominal air-dried size of 17.0 mm and 8.5 mm. Oven-died specimens were put in containers filled with water and water sorption was implemented at atmospheric pressure and room temperature. Results from the experiment could not described exactly by the model of steady state flow from Darcy' law. An empirical equation is put forward fo...
