초록
본 연구에서는 폐닥나무 섬유를 사용한 목모보드의 제조 및 조습 특성 분석을 수행하였다. 목모보드 제조를 위해 폐닥나무 섬유의 분쇄 시간을 30, 60, 120, 180초로 제어하였으며, 혼합량을 시멘트 대비 0, 3, 6, 9% 수준으로 외할 첨가하여 제어하였다. 분쇄시간 제어 조습섬유 혼입 목모보드의 흡 · 방습 특성 분석 결과, 60초 분쇄 섬유 혼합 목모보드가 흡 · 방습 성능이 뛰어난 것으로 확인되었으며, 이는분쇄 섬유의 손상이 적어 소재 자체의 흡 · 방습 성능이 보드 혼합 시에도 발현되었기 때문이다. 또한 섬유 혼합량 제어 목모보드의 흡 · 방습 특성 분석 결과, 6% 혼합 목모보드가 흡 · 방습 특성이 가장 뛰어났으며, 흡습 및 방습량은 각각 291.00g/m2 및 108.75g/m2으로 확인되었다.
Abstract
The humidity-control function and manufacturing characteristics of wood-wool boards using waste-paper-mulberry fiber were analyzed in this study. For the manufacture of wood-wool boards, the pulverizing times of waste-paper-mulberry fibers were controlled at 30, 60, 120, and 180 s, and the mixing amounts were controlled by adding 0%, 3%, 6%, and 9%, respectively, as compared to cement. Analysis of the moisture adsorption and desorption characteristics of the wood-wool boards controlled for pulverizing time revealed that the wood-wool board with 60 s of pulverized fiber exhibited the best adsorption and desorption performances. It was estimated that the adsorption and desorption performances of the material itself were adequate even when the boards were mixed because of minimal damage to the fiber. In addition, an analysis of the absorption and desorption characteristics of the fiber-mixture-controlled wood-wool boards showed that the 6%-mixed wood-wool board had the best absorption and desorption performances of 291.00 g/m2 and 108.75 g/m2, respectively.
