江原道産 참나무科 4 樹種의 推定乾燥스케쥴 = The estimated drying schedule of Fagaceae four species grown in Kangwon-Do

국문 초록 (Abstract)

江原道産 참나무科 4樹種의 乾燥特性을 파악코져 100℃에서 急速乾燥를 실시하여 乾燥中 含水率과 乾燥經過 初期割裂(木口割裂과 表面割裂), 찌그러짐, 內部割裂 등의 乾燥缺陷을 調査하여 推定乾燥스케쥴을 作成한 結果는 다음과 같다.
乾燥時間別 乾燥中 含水率은 初期含水率이 높은 板材일수록 急速한 曲線的 減少를 나타내었고 乾燥 所要時間이 길었으며 굴참나무가 乾燥中 割裂의 發生量이 가장 크게 나타났으며 구해진 推定乾燥스케쥴은 T5 - C₂였다. 또한 모든 樹種의 木理方向別 收縮率은 接線方向(T) ＞ 放射方向(R) ＞ 纖維方向(L)의 順位였으며 急速乾燥法에 의한 收縮率이 정상적인 收縮率보다 크게 나타났다.

This study was carried out to estimate drying schedule of Fagaceae four species grown in Kangwon-Do by oven-drying at 100℃ which aimed to elucidate the characteristics such as current moisture content, drying process, initial check, collapse and internal check during drying.
The results were summerized as follows ;
Current moisture content of each board showed a rapid drying curve with the hight initial moisture content of board and species with the high initial moisture content took long to do drying. Appearance of checks for Quercus variabilis were extremely severe and estimated schedule was T5 - C₂. The shrinkage rate of grain direction was in the order of tangential direction ＞ radial direction ＞ longitudial direction and the shrinkage rate of oven-drying at 100℃ was bigger than normal shrinkage rate.
