在面對火災的時候，我們要懂得判斷火災引起的原因以及怎么處理，這樣才能更好的選擇相對應的滅火器來進行滅火。那么，你知道泡沫滅火器主要用于撲滅什么火災嗎？
When facing a fire, we should know how to judge the cause of the fire and how to deal with it, so that we can better choose the corresponding fire extinguisher to put out the fire. Then, do you know what kind of fires foam extinguishers are mainly used to extinguish?
泡沫滅火器主要用來撲滅A類火災，如木材、棉布等固體物質燃燒引起的失火；適宜撲救B類火災，如汽油、柴油等液體火災；不能撲救水溶性可燃、易燃液體的火災（如：醇、酯、醚、酮等物質）和E類（帶電）火災。
Foam fire extinguishers are mainly used to extinguish class a fires, such as fires caused by the burning of solid substances such as wood and cotton cloth; Suitable for extinguishing class B fires, such as gasoline, diesel and other liquid fires; The fire of water-soluble flammable and combustible liquids (such as alcohols, esters, ethers, ketones and other substances) and class E (charged) fires cannot be extinguished.
此類滅火器是通過筒體內酸性溶液與堿性溶液混合發生化學反應，將生成的泡沫壓出噴嘴，噴射出去進行滅火的。它除了用于撲救一般固體物質火災外，還能撲救油類等可燃液體火災，但不能撲救帶電設備和醇、酮、酯、醚等有機溶劑發生的火災。
This kind of fire extinguisher is mixed with acidic solution and alkaline solution in the cylinder to produce chemical reaction, and the generated foam is pressed out of the nozzle and sprayed out to extinguish the fire. It is not only used to put out fires of general solid substances, but also can put out fires of flammable liquids such as oils, but it cannot put out fires of live equipment and organic solvents such as alcohols, ketones, esters, ethers, etc.
川消泡沫滅火器的原理十分簡單，就是在使用泡沫滅火器的時候，滅火器能夠噴射出大量的二氧化碳。泡沫滅火器的內部裝有兩個容器，一個容器盛有硫酸鋁，另一個容器裝有碳酸氫鈉溶液。這兩個容器是分別獨立的，因此這兩種化學物品互不接觸，不會發生任何化學反應。
The principle of Chuanxiao foam fire extinguisher is very simple, that is, when using foam fire extinguisher, the fire extinguisher can eject a large amount of carbon dioxide. There are two containers inside the foam extinguisher, one containing aluminum sulfate and the other containing sodium bicarbonate solution. The two containers are independent, so the two chemicals do not contact each other and no chemical reaction will occur.
當要使用泡沫滅火器時，就把滅火器倒立，使得兩種溶液相互接觸并且混合在一起，發生化學反應，產生大量的二氧化碳。不僅如此，在滅火器里還有一些發泡劑用來產生泡沫。在使用泡沫滅火器的時候打開開關，泡沫會從開口處噴出，覆蓋在物品上，隔絕氧氣并且降低燃燒物品的溫度，因而達到滅火的目的。而且噴出的泡沫里還含有大量的水分，不會產生任何污染物。
When you want to use a foam fire extinguisher, stand the extinguisher upside down, so that the two solutions contact each other and mix together to produce a chemical reaction and produce a large amount of carbon dioxide. Not only that, there are also some foaming agents in fire extinguishers to produce foam. When using the foam fire extinguisher, turn on the switch, and the foam will be sprayed from the opening to cover the items, isolate oxygen and reduce the temperature of the burning items, so as to achieve the purpose of extinguishing the fire. And the foam also contains a lot of water, which will not produce any pollutants.
由于泡沫滅火器噴出的泡沫中含有大量水分，它不如二氧化碳液體滅火器，滅火后不污染物質，不留痕跡。可用來撲滅木材，棉布等燃燒引起的失火，還能撲救油類等可燃液體火災。
Because the foam emitted by the foam extinguisher contains a lot of water, it is not as good as the carbon dioxide liquid extinguisher, which does not pollute substances and leave no traces after extinguishing. It can be used to put out fires caused by the burning of wood, cotton cloth, etc., and also to put out fires caused by flammable liquids such as oil.
