Effects of acetylation and formalization on the dynamic water vaporn sorption behavior of wood

摘要

The dynamic water vapor sorption of untreated, acetylated (W-ac), and formaldehyde-treated (W-FA) Scots pine (Pinus sylvestris L.) sapwood was studied in a dynamic vapor sorption apparatus to assess the effects of cell wall bulking and cross-linking. Both modifications resulted in a considerable reduction of reduced equilibrium moisture content (EMCR), the corresponding equilibrium times, and hysteresis in the hydroscopic range of wood. Acetylation reduced the adsorption and desorption of water
