본 연구는 국내산 목재의 효율적인 이용과 이용확대를 목표로, 낙엽송, 소나무 그리고 백합나무의 도장처리에 따른 흡수성과 방사방향 및 접선방향 의 고습환경하의 팽윤율을 조사하였다. 도장처리재는 미처리재에 비해 3수종 모두 고습환경에 노출 된 후 150시간 이후의 흡수율은 작게 나타났고, 도장처리재의 흡수율은 백합나무(2.2%) > 소나무(2.1%) > 낙엽송(1.9%)의 순이었다. 고습환경에 노출된 후 150시간 이후의 함수율은 흡습량에 비례하여 증가하였고, 그 크기는 백합나무 > 낙엽송 > 소나무의 순이었으나, 소나무의 경우 양자의 차이가 적은 것이 확인되었다. 도장처리재의 방사방향 팽윤율은 2.18% - 3.44%의 범위였고, 그 크기는 낙엽송이 백합나무나 소나무에 비해 현저히 적은 값을 나타내었다. 또한, 도장처리재의 접선방향 팽윤율은 4.17% - 6.36%의 범위에 있었고, 이 값은 방사방향과 같이 낙엽송이 가장 적었고, 소나무, 백합나무의 순이었다. 이 값은 미처리재에 비하여 0.85 – 0.96배의 적은 값을 나타내었고, 방사방향의 약 1.9배 높은 값을 나타내는 것이 확인되었다.

With the goal of efficient use and expansion of domestic wood, this study investigated the water absorption, the swelling ratio for the radial directions and tangential directions of larch, red pine and tulip tree in a high-humidity environment according to painting treatment. Surface painted wood showed a lower increase in moisture absorption for all three wood species in a high-humidity environment compared to untreated wood, and the extent according to surface painted wood species was in the order of tulip tree (2.2%) > red pine (2.1%) > larch (1.9%). After 150 hours of exposure to a high-humidity environment, the moisture content increased in proportion to the amount of moisture absorption, and the size of the moisture content was in the order of tulip tree > larch > red pine, but in the case of red pine, the difference between the surface painted and untreated was confirmed to be small. The swelling ratio for radial direction of the painted wood was in the range of 2.18% - 3.44%, and its size was significantly smaller for larch than for tulip tree or red pine. In addition, the swelling ratio for tangential direction of the painted woods was in the range of 4.17% - 6.36%, and this value was in the order of larch, red pine, and tulip tree, as in the radial direction. This value was 0.85 – 0.96 times lower than that of the untreated wood, and was confirmed to be approximately 1.9 times higher in the radial direction.
