泡沫滅火劑滅火時(shí)，在液體表面產(chǎn)生泡沫漂浮層，可附著在可燃物上，使可燃物與空氣隔離，發(fā)揮窒息和冷卻作用，達(dá)到滅火的目的，包括化學(xué)泡沫、空氣泡沫、氟蛋白泡沫、水成膜泡沫和抗溶性泡沫。當(dāng)使用泡沫滅火劑滅火時(shí)，我們應(yīng)該注意什么？下面
川消小編來為您講解。
When putting out a fire with foam extinguishing agent, a foam floating layer is generated on the surface of the liquid, which can attach to the combustibles, isolate the combustibles from the air, play the role of suffocation and cooling, and achieve the purpose of extinguishing the fire, including chemical foam, air foam, fluoroprotein foam, aqueous film forming foam and insoluble foam. When using foam extinguishing agent, what should we pay attention to? Now let's talk about it.
1.空氣泡沫滅火劑不應(yīng)在高溫下使用?？諝馀菽瓬缁饎┲饕揽糠e聚的氣泡群來滅火。在高溫下，氣泡會(huì)被加熱、膨脹、破壞、丟失或減少滅火效果。
1. Air foam extinguishing agent shall not be used under high temperature. Air foam extinguishing agent mainly relies on accumulated bubbles to extinguish fire. Under high temperature, bubbles will be heated, expanded, destroyed, lost or reduce the fire extinguishing effect.
2.非抗溶性泡沫滅火劑不能用于撲滅水溶性可燃液體的火災(zāi)。醇.醚.醛.酮等有機(jī)溶劑易溶于水，破壞泡沫。在這種情況下，使用抗溶性泡沫滅火劑滅火。
2. The insoluble foam extinguishing agent cannot be used to extinguish the fire of water-soluble flammable liquid. Alcohols, ethers, aldehydes Organic solvents such as ketones are easily soluble in water and destroy foam. In this case, use insoluble foam extinguishing agent to extinguish the fire.
3.化學(xué)泡沫滅火劑不能用于撲滅避水、避酸的化學(xué)物質(zhì)和電氣設(shè)備的火災(zāi)。泡沫滅火劑中電解質(zhì)強(qiáng)，導(dǎo)電性強(qiáng)，不能滅火。
3. The chemical foam extinguishing agent cannot be used to extinguish the fire of chemical substances and electrical equipment that avoid water and acid. The foam extinguishing agent has strong electrolyte and strong conductivity, so it cannot extinguish the fire.
4.高倍數(shù)泡沫滅火劑不能用于滅火罐。高倍數(shù)泡沫的比例很小，油箱的熱氣流升力很大，使泡沫無法覆蓋油表面。
4. High expansion foam extinguishing agent cannot be used for fire extinguishers. The proportion of high expansion foam is very small, and the lift force of hot air flow in the oil tank is very large, so that the foam cannot cover the oil surface.
注意泡沫滅火劑的儲(chǔ)存溫度，一般為0~40℃。儲(chǔ)存溫度過高或過低會(huì)影響泡沫滅火劑的質(zhì)量和儲(chǔ)存期。選擇干燥、陰涼、通風(fēng)干燥的儲(chǔ)存場(chǎng)所，避免陽光直射，防止雜質(zhì)與其他物質(zhì)混合。
Pay attention to the storage temperature of foam extinguishing agent, which is generally 0~40 ℃. High or low storage temperature will affect the quality and storage period of foam extinguishing agent. Select a dry, cool, ventilated and dry storage place, avoid direct sunlight, and prevent impurities from mixing with other substances.
要采用高密度聚乙烯容器包裝。水成膜泡沫滅火劑、抗溶性泡沫滅火劑等腐蝕性大，對(duì)防腐涂料有特殊要求，應(yīng)注意。更多相關(guān)內(nèi)容就來我們網(wǎng)站

High density polyethylene containers shall be used for packaging. Water film-forming foam extinguishing agent, soluble resistant foam extinguishing agent and other corrosive agents have special requirements for anti-corrosion coatings, which should be noted.
