영문 초록

Hygroscopicity and anistropicity are most important physical properties of wood. Wood shrinks with the loss of water and the dimensional shrinkages are different in the three directions. Anistropical shrinkage causes drying stresses and finally cracks in wood. Wood sta-bilizer penetrates into wood and prevent it from shrinking. Three wood stabilizers (products A and B, PEG-1000) are popular and available in global on-line market. Red pine disks of 5 cm thickness were soaked in these three wood stabilizer solutions. Absorption rate, drying rate, amount of retention and equilibrium moisture content were examined to compare their properties. For Product B and PEG-1000 green wood disks were soaked. Absorption rate of Product B was higher than PEG-1000 by 10 times. Drying rates of soaked wood disks in a cardboard box were 0.23, 1.13, and 3.2 g/day for Products A and B, and PEG-1000, respectively. Amount of re-tention based on oven-dry weight were 14.7, 23.1, and 32.6% for Products A and B, and PEG-1000, respectively. It was revealed by a chemical analysis that Products A and B are hy-drotreated petroleum.
