Abstract

In the study, fire extinguishing concentration of $K_2CO_3$-Zeolite composite was measured. Zeolite composite is a porous adsorbent which has small particle size, low density and anti-catalytic effect. Scanning Electron Microscopy, X-Ray diffraction and thermal analysis were also conducted to investigate the structural properties of composite. The result showed that despite of weight ratio, the extinguishing concentration of the composite was lower than pure $K_2CO_3$. The extinguishing concentration of $K_2CO_3$-Zeolite composite which has weight ratio of 7 : 3 was 5.72 times lower than that of pure $K_2CO_3$ and 1.1 times lower than that of ABC powder. The SEM and XRD patterns showed that $K_2CO_3$ was adsorbed on the Zeolite properly, and through the thermal analysis, it was founded that the composite is more effective extinguishing agent than pure $K_2CO_3$.

본 연구에서는 입자크기 및 밀도가 비교적 작고 소화효과에 있어서 부촉매효과를 나타내는 다공성 흡착제인 합성제올라이트에 $K_2CO_3$를 중량비에 따라 흡착시킨 구조체의 소화농도를 측정하였다. 그리고 구조적 특성을 파악하고자 주사전자 현미경(SEM)의 측정 및 X-Ray 회절분석, 열분석 등을 실시하였다. 흡착구조체의 소화농도실험에서 중량비에 관계없이 순수 $K_2CO_3$의 소화농도보다 모두 낮게 나타났다. 그리고, 특히 $K_2CO_3$와 합성제올라이트의 중량비가 7 : 3인 경우는 소화농도가 5.72배 낮게 측정되었고 ABC분말소화약제보다 약 1.1배 낮게 나타났다. SEM 사진 및 XRD 회절패턴분석을 통해 $K_2CO_3$가 합성제올라이트에 흡착되었다는 것을 알 수 있었고, 열분석을 통해 흡착구조체가 순수 $K_2CO_3$보다 소화에 긍정적인 영향을 미쳤을 것이라 추정할 수 있었다.
