Abstract

After produce the extracted wood to silicic acid gel, sodium carbonate and silicon dioxide with application of the making method for carbon dioxide, ignition time, ignition temperature, mass loss rate and critical heat flux are measured according to external radiation source (20, 25, 35 and 50 $kW/m^2$). From the results, pressure impregnation wood to use with water glass and carbon dioxide has fire retardant performance at heat flux (less than 20 $kW/m^2$) of Pre-Flashover fires. If we find out the excellent maxing ratio through continuously study, it might be decided to be able to be utilized as fire-retardant wood.

이산화탄소 주조법에서 사용되고 있는 방법을 응용하여 목질내에 규산겔과 탄산소다, 이산화규소가 석출된 목재를 제조한 후 외부 복사열원(20, 25, 35 및 50 $kW/m^2$)에 따른 점화시간, 점화온도, 질량감소속도, 임계열유속을 측정하였다. 연구결과, 물유리와 이산화탄소를 이용한 가압함침 처리된 목재는 Pre-Flashover 단계에서의 복사열원(20 $kW/m^2$ 이하)에서 난연성능이 있음을 확인할 수 있었다. 향후 지속적인 연구를 통해 우수한 배합비율을 찾는다면 난연목재로서의 활용가능성이 있다고 판단된다.
