초록

수성막포(aqueous film forming foam, AFFF)는 함정 유류화재 대응에 핵심적인 역할을 하는 주요 소화약제 중 하나이다. 이 형태의 소화약제는 막 형성, 열 제거, 연소 억제, 그리고 화학 물질 혼합물을 이용하여 화재를 진압하는 데 효과적이다. 이러한 특성은 유류화재 대응에 있어서 큰 장점을 제공하지만, AFFF는 폼 형태로 분사되어 화재에 대응하는 과정에서 기존 유체와 차별점을 가진다. 따라서 AFFF 폼의 레오미터를 활용한 유변학적 특성 분석은 함정 유류화재 대응을 위한 AFFF 분사 특성 예측에 핵심적인 역할을 수행하며, 이는 효과적인 화재 진압과 밀접한 연관이 있다. 본 연구에서는 레오미터 실험을 통해 AFFF 폼의 비뉴턴 유체(전단박화) 거동을 확인하였으며, 폼의 안정성과 직결되는 데이터들을 얻을 수 있었다. 이러한 실험 데이터들은 AFFF를 활용한 소화 시스템의 효율성을 높이는데 기여할 것으로 기대된다.

Aqueous film forming foam (AFFF) is a critical fire suppression agent used in combating hydrocarbon fires. This type of fire suppressant is highly effective due to its ability to form a protective film, dissipate heat, inhibit combustion, and utilize a blend of chemical substances to extinguish fires. While these properties offer significant advantages in responding to hydrocarbon fires, AFFF is distinct in its deployment as it is dispensed in the form of foam. Therefore, the rheological analysis of AFFF foam using a rheometer plays a crucial role in predicting the spray characteristics of AFFF for combating hydrocarbon fires, and this is closely associated with effective fire suppression. In this study, we conducted rheometer experiments to confirm the non-Newtonian behavior (shear-thinning) of AFFF foam and obtained data on the form's stability. These experimental data are expected to contribute to enhancing the efficiency of fire suppression systems utilizing AFFF.
