목타르와 목초액로 처리한 낙엽송재의 Weathering 특성

This study has been carried out to investigate the preservation characteristics and weathering of larch wood treated with wood tar and wood vinegar, neglected under the circumstance of outdoor exposure, buried under ground, and deposited under water. Earlywood cell wall observed by optical microscope has been collapsed due to the fungi deterioration. This phenomenon occurred more frequently in the case of woods treated with wood tar and buried under ground. Relative crystallinity of woods treated with wood tar, exposed outdoors, and untreated wood buried under ground was highest at 63% while wood tar treated wood buried under ground was lowest at 46%.
