Abstract

A current standard exist only on the surface tension in the current domestic wetting agent technology standards, so it is difficult to the performance evaluation of the wetting agent through the standard. So this study presents the optimized performance evaluation methods by scale model experimental equipment in order to present techniques for performance evaluation of wetting agents. The purpose of this study is to investigate validity of experimental results of the self-designed scale model experiment equipment by a comparative analysis of experimental results of the NFPA 18 experiment and the experiment using the self-designed scale model experiment equipment. As a result of a comparative analysis of experimental results of the NFPA 18 experiment that evaluate only the permeation performance on the contton and the experiment using the self-designed scale model experiment equipment that evaluate the permeation performance and fire extinguishing performance on wood flour, the discrimination of the permeation performance was confirmed in both the NFPA 18 experiment and the self-designed scale model experiment equipment. And a result of self-designed experiment equipment have clear discriminatory more than NFPA 18 by internal temperature measurement using the thermocouples.

현재 국내의 침윤소화약제 기술기준은 표면장력에 대한 기준만 존재하여 이를 통한 약제의 성능평가는 어려운 실정이다. 따라서 침윤소화약제의 성능평가 기법을 제시하기 위해 축소모형 실험 장치를 통한 최적화된 성능평가 방법을 제시하고자 한다. 본 연구는 해외 기준인 NFPA 18의 실험과 자체 제작된 축소모형 실험 장치를 이용한 실험의 결과 비교분석을 통해 자체 제작 축소모형 실험 장치실험 결과의 타당성을 규명하고자 한다. 목화솜을 대상으로 침투성능만을 평가하는 NFPA 18 실험과 목분을 대상으로 침투성능과 소화성능을 모두 평가하는 축소모형 실험을 비교분석한 결과 NFPA 18의 실험과 자체 제작 축소모형 실험에서 모두 소화용수의 침투성에 관한 변별력을 확인할 수 있었다. 또한 자체 제작 축소모형 실험에서는 T/C를 통한 내부온도 측정을 통해 보다 명확한 변별력을 나타냄을 확인하였다.
