요약
본 연구에서는 최근 조경 및 건축자재로서 각광받고 있는 합성목재의 화재위험성을 알아보기 위하여 콘칼로리미터 실험과 연기밀도 실험 장치를 이용하여 연기밀도 특성을 살펴보았다. 일반목재인 적송과 방부처리를 한 방부목에 대하여도 동일한 실험을 통하여 합성목재와의 연기밀도 특성을 비교하였다. 콘칼로리미터 실험결과 CO 및 $CO_2$ 발생량과 총 연기 발생량 값은 적송 및 방부목에 비해 합성목재가 높게 나타났다. 또한 연기밀도 실험 장치를 통한 최대연기밀도(Dm) 결과에서도 합성목재가 적송 및 방부목에 비해 높게 나타났다.
Abstract
In this study, we measured the smoke density characteristics to find the fire risk of Wood-Plastic composites (WPCs) which are one of spotlighting materials for landscape architecture and residential construction material with the cone calorimeter tester (by ISO 5660-2) and the smoke density tester (by ASTM E 662). In addition, the identical test was implemented to compare the smoke density characteristics between the red pine and the antiseptic wood. The result of cone calorimeter test showed that emissions of carbon monoxide, carbon dioxide and total smoke production rate of WPCs were higher than those of red pine and antiseptic wood. And the result of smoke density test showed that maximum specific optical smoke density(Dm) of WPCs was higher than that of red pine and antiseptic wood as well.
Key Words: Wood-plastic composites, Smoke density, Cone calorimeter, Total smoke release, Smoke factor
