川消泡沫滅火劑在撲救液體火災充當著不可替代的角色，在石油化工處置中，提出了全泡沫戰術的理念，對泡沫的發泡質量有著較高的要求，另一方面對泡沫的持續供給時間的強調更是考驗消防救援隊伍對泡沫使用的能力。今天小編通過整理各個資料讓大家對泡沫滅火劑有一個系統的認識：
Chuanxiao foam extinguishing agent plays an irreplaceable role in fighting liquid fires. In petrochemical disposal, it has put forward the concept of full foam tactics, which has high requirements for the foam quality of foam. On the other hand, the emphasis on the continuous supply time of foam is a test of the ability of fire rescue teams to use foam. Today's editor gives you a systematic understanding of foam extinguishing agent by sorting out various materials:
一、關于泡沫滅火劑的幾個名詞概念
1、 Some Concepts of foam Extinguishing Agent
①泡沫原液：泡沫原液是指從廠家購買時原裝的液體。
① Foam stock solution: foam stock solution refers to the original liquid purchased from the manufacturer.
②泡沫混合液：泡沫混合液是指泡沫原液和水按照混合比例混合之后的液體。
② Foam mixture: foam mixture refers to the liquid after foam stock solution and water are mixed in proportion.
③泡沫：泡沫是指泡沫混合液經過空氣的混合、發泡，產生的白色泡沫。
③ Foam: foam refers to the white foam produced by the mixing and foaming of foam mixture through air.
二、泡沫滅火劑的幾個性能指標
2、 Several performance indexes of foam extinguishing agent
①抗凍結、融化性能：這是衡量泡沫液穩定性的一個性能參數。
① Anti freezing and melting performance: this is a performance parameter to measure the stability of foam liquid.
衡量標準實驗：（在低于其凝固點10℃的溫度下凍結，在室溫下解凍放置24h~96h重復三次，完成4次凍結和融化周期，觀察泡沫原液有無分層、非均勻或沉淀現象，有則代表泡沫性能差。）
Measurement standard experiment: (Freeze at a temperature 10 ℃ lower than its freezing point, thaw at room temperature for 24h~96h and repeat three times to complete four freezing and thawing cycles, and observe whether foam stock solution has stratification, non-uniformity or precipitation, which indicates poor performance of foam.)
②PH值：一般泡沫的PH值都在6~9之間，接近中性，超過這個范圍會腐蝕存儲物也表示泡沫的性能較差。
② PH value: Generally, the PH value of foam is between 6 and 9, which is close to neutral. If the PH value exceeds this range, it will corrode the storage, which also means that the performance of foam is poor.
③沉淀物：一般泡沫滅火劑的沉降物要盡量少。
③ Sediment: generally, the sediment of foam extinguishing agent should be as little as possible.
④流動性：是衡量泡沫液流動狀態的性能參數。
④ Liquidity: It is a performance parameter to measure the flow state of foam concentrate.
⑤擴散系數：是衡量泡沫液在另一種液體表面上擴散能力的參數。
⑤ Diffusion coefficient: it is a parameter to measure the diffusion ability of foam liquid on the surface of another liquid.
⑥混合比：是指泡沫原液與水混合的體積百分數。例如3％型的泡沫液的混合比為3％，一百份的混合液中水占97％泡沫原液占3％。
⑥ Mixing ratio: refers to the volume percentage of foam stock solution mixed with water. For example, the mixing ratio of 3% type foam liquid is 3%, and water accounts for 97% of 100 parts of the mixed liquid, and the foam stock solution accounts for 3%.
⑦發泡倍數：發泡倍數是指泡沫液按規定的混合比與水混合制成的混合液，泡沫混合液發泡產生的泡沫的體積與泡沫混合液的體積比值。消防隊伍日常使用的低倍數泡沫滅火劑的發泡倍數一般在6~8倍，我國的現行泡沫的發泡倍數為6.25倍。
⑦ Foaming multiple: The foaming multiple refers to the mixture of foam liquid and water according to the specified mixing ratio. The volume ratio of foam produced by foam mixture foaming to the volume of foam mixture. The low expansion foam extinguishing agent commonly used by the fire brigade has a foaming ratio of 6~8 times, and the current foam in China has a foaming ratio of 6.25 times.
⑧25％析液時間和50％析液時間：是指從泡沫生成開始到泡沫分別析出25％和50％質量液體所用的時間，這是衡量泡沫穩定性的重要參數，時間越慢則代表泡沫的穩定性越好。
⑧ 25% and 50% liquid separation time: refers to the time from the beginning of foam generation to the time when foam separates 25% and 50% liquid, which is an important parameter to measure the stability of foam. The slower the time, the better the stability of foam.
⑨滅火時間：是指從噴射泡沫開始，火焰全部熄滅的時間。
⑨ Extinguishing time: refers to the time from spraying foam to extinguishing all flames.
⑩抗燒時間：是衡量低倍數泡沫的熱穩定性和抗燒性能的一個指標。
⑩ Burning resistance time: it is an index to measure the thermal stability and burning resistance of low expansion foam.
This is the end of the term, concept and performance index of foam extinguishing agent. I hope it can help you. More matters can come to our website http://www.xintli.net Consultation and understanding!
