川消泡沫灭火剂在扑救液体火灾充当着不可替代的角色，在石油化工处置中，提出了全泡沫战术的理念，对泡沫的发泡质量有着较高的要求，另一方面对泡沫的持续供给时间的强调更是考验消防救援队伍对泡沫使用的能力。今天小编通过整理各个资料让大家对泡沫灭火剂有一个系统的认识：
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、关于泡沫灭火剂的几个名词概念
1、 Some Concepts of foam Extinguishing Agent
①泡沫原液：泡沫原液是指从厂家购买时原装的液体。
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体。
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经过空气的混合、发泡，产生的白色泡沫。
③ Foam: foam refers to the white foam produced by the mixing and foaming of foam mixture through air.
二、泡沫灭火剂的几个性能指标
2、 Several performance indexes of foam extinguishing agent
①抗冻结、融化性能：这是衡量泡沫液稳定性的一个性能参数。
① Anti freezing and melting performance: this is a performance parameter to measure the stability of foam liquid.
衡量标准实验：（在低于其凝固点10℃的温度下冻结，在室温下解冻放置24h~96h重复三次，完成4次冻结和融化周期，观察泡沫原液有无分层、非均匀或沉淀现象，有则代表泡沫性能差。）
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之间，接近中性，超过这个范围会腐蚀存储物也表示泡沫的性能较差。
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：一般泡沫灭火剂的沉降物要尽量少。
③ Sediment: generally, the sediment of foam extinguishing agent should be as little as possible.
④流动性：是衡量泡沫液流动状态的性能参数。
④ Liquidity: It is a performance parameter to measure the flow state of foam concentrate.
⑤扩散系数：是衡量泡沫液在另一种液体表面上扩散能力的参数。
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：是指泡沫原液与水混合的体积百分数。例如3％型的泡沫液的混合比为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发泡倍数：发泡倍数是指泡沫液按规定的混合比与水混合制成的混合液，泡沫混合液发泡产生的泡沫的体积与泡沫混合液的体积比值。消防队伍日常使用的低倍数泡沫灭火剂的发泡倍数一般在6~8倍，我国的现行泡沫的发泡倍数为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％析液时间和50％析液时间：是指从泡沫生成开始到泡沫分别析出25％和50％质量液体所用的时间，这是衡量泡沫稳定性的重要参数，时间越慢则代表泡沫的稳定性越好。
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灭火时间：是指从喷射泡沫开始，火焰全部熄灭的时间。
⑨ Extinguishing time: refers to the time from spraying foam to extinguishing all flames.
⑩抗烧时间：是衡量低倍数泡沫的热稳定性和抗烧性能的一个指标。
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.cx-fire.com Consultation and understanding!
