山东川消：干粉灭火器遇粉尘会爆炸？真相来了

来源：http://www.cx-fire.com/ 日期：2026-02-25

　　这是一堆普通的面粉，这是我们常用的干粉灭火器

　　This is a pile of ordinary flour, and this is our commonly used dry powder fire extinguisher

　　上一个视频评论区里面有网友说粉尘爆炸的关键是粉尘，什么粉尘都会爆炸，那关键是不是这样子呢？好，那我问你了，灭火器喷出来的粉尘漫天飞舞会不会爆炸呢？

　　In the comments section of the previous video, a netizen said that the key to dust explosion is dust, and any dust can explode. Is that the key? Okay, let me ask you, will the dust sprayed from the fire extinguisher explode if it flies all over the sky?

　　各位，我们首先要明白一个点，不是所有的粉尘都能爆炸。能爆炸的粉尘呢，必须是可燃粉尘，比如像面粉，淀粉，木屑，煤粉这一些呢，它们就是属于可燃的粉尘，一旦漂浮在空中，形成了悬浮的粉尘云，遇到明火就会瞬间爆燃。

　　Everyone, first of all, we need to understand that not all dust can explode. The explosive dust must be combustible dust, such as flour, starch, sawdust, coal powder, etc. They belong to combustible dust. Once floating in the air, they form a suspended dust cloud, which will explode instantly when exposed to an open flame.

　　当然了，像这一堆固体的粉末，它不容易燃烧，因为它跟氧气接触面积小，但是如果燃起来形成了悬浮的粉尘，这颗粒呢，就会被氧气包裹。

　　Of course, solid powders like this are not easy to burn because they have a small contact area with oxygen. However, if they ignite and form suspended dust, these particles will be enveloped by oxygen.

　　火遇到明火就会连锁的燃烧。如果在室内高温的燃烧呢，会产生大量的气体，内部的压力骤升，爆炸的威力就会成倍放大，这非常危险。这就是为什么一定要禁止将炮弹插在面粉上点燃，或者禁止在粉尘堆积的地方燃放烟花爆竹。

　　Fire will ignite in a chain reaction when it encounters an open flame. If burned at high temperatures indoors, a large amount of gas will be produced, causing a sudden increase in internal pressure and doubling the power of the explosion, which is very dangerous. That's why it's essential to prohibit firing shells on flour or setting off fireworks and firecrackers in areas with accumulated dust.

　　那灭火器的干粉燃起来会不会爆燃呢？其实干粉里面的主要成分呢，就是磷酸二氢胺，它本身呢是不可燃的作用，就是隔绝专门用于灭火，它并没有燃烧的基础，所以呢，不管飘多浓阳多高，遇到明火都不会炸唉。这个是什么牌子这么好用，所以不是粉尘会爆炸，关键是它可不可燃好吧，

　　Will the dry powder of the fire extinguisher ignite? In fact, the main component in dry powder is dihydrogen phosphate, which is non flammable and specifically used for fire extinguishing. It does not have a basis for combustion, so no matter how concentrated or high the sun is, it will not explode when exposed to an open flame. What brand is this so easy to use, so it's not that dust will explode, the key is that it's not flammable, okay,

　　今天课到这里就结束了，在这里呢，给各位朋友送上我跟小马的祝福，大家都是祝你们马年发大财，我跟小马呢，祝大家马年不马虎，平安每一年我们！

　　That's all for today's class. Here, I would like to send my and Xiaoma's wishes to all friends. We all wish you great wealth in the Year of the Horse, and I and Xiaoma wish you all the best in the Year of the Horse and peace every year!
