초록

본 연구는 건축 재료(마감재)로 쓰이고 있는 목재 나무류 미송, 나왕, 삼나무, 소나무 등4종의 구조와 연소특성을 연구하였다. 착화특성을 보면 착화시간(TTI)범위가 21 s~32 s으로나타났으며 특히 소나무는 TTI가 21 s로 다른 재료들보다 비교적 빠른 601 s에 착화되어 631 s에 소멸되었다. 최대열방출율과 평균열방출율은 소나무 > 나왕 > 삼나무 > 미송 순으로 나타내었다. 총열방출량은 나왕 > 미송 > 소나무 > 삼나무 순이었다. 총연기방출량은 소나무가 $424.80m^2/m^2$, 나왕 $185.93m^2/m^2$이었다. 탄소배출량은 미송이 1,460 s에서 0.185 kg/kg CO 최대값을 보이고 $CO_2$ 값은 750 s에서 15,986 kg/kg으로 최대값을 보이다 3,090 s에서 정지되었다. 향후, 건축 재료로서 화재의 안전성을 평가하기 위한 기초 자료로 활용하는 방안을 제시하였다.

This study investigated the structure and combustion characteristics of four species, Timber Douglas-fir being used construction materials (finishes), Lauan, Cryptomeria japonica, Pinus densiflora trees in the area. In lookong into the ignition characteristics was a time range of ignition (TTI) appeared in the 21 s~32 s, especially Pinus densiflora TTI is ignited in a relatively rapid 601 s to 21 s than the other materials were destroyed in the 631 s. The maximum heat release rate and average heat release rate is Pinus densiflora > Lauan > Cryptomeria japonica > Douglas-fir showed a net. Barrel emissions are Lauan > Douglas-fir > Pinus densiflora > Cryptomeria japonica was in order. The total emissions was postponed Pinus densiflora $424.80m^2/m^2$, Lauan $185.93m^2/m^2$. Douglas-fir carbon emissions of 1460, showing 0.185 kg/kg CO maximum value from s $CO_2$ values show the maximum value to 15,986 kg/kg in 750 s stopped in the 3,090 s. Next, the study suggested methods to utilize as the basic data for evaluating the safety of the fire as a building material.
