ANALYSIS OF THE WOOD-WETTING PROCESS

The analysis of water-wetting of wood was performed. Basic characteris tics for wetting process were defined and determined experimentally - the contact angle at the beginning of wetting THETA(o) and the equilib rium contact angle THETA(u). Based on these characteristics, the conta ct angle, signed as THETA(w), corresponding to ideal smooth wood surfa ce was determined. The results were used for the computation of free w ood - surface energy and compared with the data from literature.
