Cypress woods treated individually with boric acid (BA4), ammonium pentaborate (APB4), or BA4/APB4 additives were examined for combustion gases. Each of the specimens was painted with a 4 wt% solution of boron compounds three times. Dried at room temperature, the combustion gas was analyzed using a ...

목재는 어떠한 위험성이 있는가? | 친환경적인 내구재 및 건자재로 널리 사용되는 목재는 화재 시 연소되기 쉬움으로써 화재안전성 측면에서 높은 위험성을 가지고 있다. 따라서 이와 같은 목재의 단점을 보완하기 위해 다양한 난연 처리 방법들이 연구되어 왔다[1-4]. | |
목재의 난연 처리는 어떠한 방법들을 이용하는가? | 따라서 이와 같은 목재의 단점을 보완하기 위해 다양한 난연 처리 방법들이 연구되어 왔다[1-4]. 목재의 난연 처리는 인화합물계, 질소화합물계, 붕소화합물계, 실리콘화합물계 등을 사용하여 처리하였다 [5-8]. 화재에 의한 피해는 약 75~80%가 연기와 유독가스 등의 흡입과, 또는 산소 결핍에 의한 것으로 조사되었다[9]. | |
콘칼로리미터는 어떠한 방법인가? | 열방출률 측정방법 중의 하나가 콘칼로리미터(cone calorimeter)이다[15]. 이것은 실 화재 현상에 대한 가장 근접하게 모사한 방법으로써 대부분의 유기재료가 연소 중에 산소 1 kg이 소비되면 약 13.1 MJ의 열이 방출되는 산소 소비 원리를 바탕으로 하고 있다[16]. 건조한 목재의 기본 조성은 탄소(C) 50%, 수소(H) 6%, 산소(O) 44%로 구성되고 그 밖에 소량의 무기화합물과 질소(N)로 구성되어 있다. |
