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。

研究進行某一品牌泡沫原液不同濃度比例之研究,依序以體積比將泡沫原液與水混合,分別進行100%(泡沫原液)、90%(10%水+90%泡沫原液)、80%(20%水+80%泡沫原液)、60%(40%水+60%泡沫原液)、40%(60%水+40%泡沫原液)及20%(80%水+20%泡沫原液)之交流阻抗分析量測。同一品牌進行加水稀釋進行不同濃度之泡沫滅火系統實際放射試驗,以觀察各種濃度之發泡膨脹情況,共計進行九次實際放射試驗,經比對交流阻抗分析量測及實際放射試驗,得到90%以上之濃度係為此品牌可接受之範圍,也因此可得知泡沫原液維持一定濃度,係為能否有效滅火的關係因子。

本研究提供之檢測方法可清楚判斷泡沫原液之品質,可以分成兩類檢測方法,第一種為原液之品牌辨識,第二種為原液之品質控制,說明如下:
(1) 第一種(原液之品牌辨識):可將販售者提供之泡沫原液導納值,紀錄於電腦資料庫中,日後當要再確定泡沫原液之品牌時,可使用先前之電腦資料以為比對判斷之依據。
(2) 第二種(原液之品質控制):當泡沫原液品牌已知時,但不知其品質是否能符合規定(有可能是保存溫度或年限影響),可使用本方法進行導納值量測,當導納值低於90%以下曲線圖形時(不同品牌有不同之可接受濃度,要另進行試驗,本研究僅以某一品牌為例),不視為合格或得繼續使用之泡沫原液,需要再進行泡沫實際放射試驗,反之,當導納值高於90%以上曲線圖形時,則視為安全之泡沫原液,無須再進行泡沫實際放射試驗。


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 liquid concentrates 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.
The concentrates with different concentration ratios of one brand were tested, according to volume ration, the foam liquid concentrates were mixed with water to conduct respectively the following AC impedance tests: 100% of foam liquid concentrate, 10% of water mixed with 90% of foam liquid concentrate, 20% of water mixed with 80% of foam liquid concentrate, 40% of water mixed with 60% of foam liquid concentrate, 60% of water mixed with 40% of foam liquid concentrate, and 80% of water mixed with 20% of foam liquid concentrate. All of AC impedance were analyzed and measured; the same brand was diluted with water to obtain different concentrations for actual foam extinguishing spraying test. Through nine tests, the foaming situations from different concentrations were recorded; comparing the results from AC impedance tests and actual foam extinguishing spraying test, we believed that the tolerance scope of this brand was 90% concentration; also we knew that a degree of concentration of foam liquid concentrate was a major factor to effectively extinguish fire.
The inspection method that this research offers can clearly identify the quality of foam liquid concentrate; there are two applications, the first is brand recognition, second one is quality control of foam liquid concentrate. The explanations are as follows:
(1) Brand Recognition for foam liquid concentrate: Set the admittance value offered by seller into database of computer so as to become a comparing foundation. Once brand identification is necessary, the database can be used as a comparison.
(2) Quality control of foam liquid concentrate: When a brand is confirmed but its quality remains uncertain (for example: violation of regulations such as storage temperature or shelf life influence), this quality control method may be used for measuring admittance value. When an admittance value is lower than 90% of curve diagram (ex: different brand with different acceptable concentrations which should do a test. this research takes one brand for example.), the quality of foam liquid concentrate will not be seen as qualified for using, and an actual spray foam test should be conducted; in contrast, when an admittance value is higher than 90% of curve diagram, the quality of foam liquid concentrate is seen as safe and no need for actual spraying test.
This research hopes to develop a simpler, 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.
