利用交流阻抗法分析消防泡沫液之滅火性能研究

Electrochemical Impedance Spectroscopy Study on the Fire Extinguishing Performance of Foam

室內停車場車輛一旦發生火災，燃燒快速及延燒迅速，嚴重威脅人命及財物，故各國依規定須設置泡沫滅火系統。目前有關泡沫原液之品質管控，世界各國係以實際放射泡沫來確認，皆要耗費相當的時間、金錢及人力，本研究係世界上首次運用電化學交流阻抗分析儀於泡沫原液的測試，可從「頻率－導納」關係圖形掌握泡沫原液之狀況，作為判斷泡沫效能之依據，試驗結果證明這是一種可行的試驗方法。本研究希望以此發展出更為簡便、正確、有效、經濟的泡沫原液檢驗替代方式，提供政府部門抽查及專業技術人員檢修之新方法，以節省時間、金錢及人力，並兼顧保護地球環境之普世責任。

Once a vehicle in indoor parking lot catches fire, it will burn quickly and spread rapidly, and then cause a serious threat to human life and property, so each country requires that building owners should set up a foam fire extinguishing system in accordance with regulations. So far, countries worldwide confirm the method of quality control of related foam concentrate based on actual foam spraying, which spends considerable time, money and manpower. This research is the first in the world that conducts a test on foam liquid concentrates by using electrochemical AC impedance analyzer to grasp the condition of foam liquid concentrates from “Frequency - admittance＂ relation diagram; the test result might be a basis for judging the performance of foam liquid concentrates. The test results show that this is a feasible test method. This research hopes to develop a more simple, accurate, effective and economical inspection method for quality control of foam liquid concentrates, the finding which may be a new solution for government checking and technician repairing. Prospectively, the new solution may save time, money and manpower, furthermore, demonstrate the universal responsibility of protecting global environment.
