不要小看防火卷帘门，它虽然外表看着只是一个普通的门，但是它除了具有普通门的功能以外，更大的作用是发挥防火作用，当发生火灾时，它的耐火性稳定性、隔热性，可以阻止火势蔓延，减缓烟气扩散，大程度的减少人身财产损失，为救援争取更多时间，挽救更多的生命和财产。那么，防火卷帘门是利用什么原理防火的？下面济南卷帘门厂为您解析一番。

Don't underestimate the fire rolling shutter door. Although it looks like an ordinary door, it plays a more important role in fire prevention besides the function of an ordinary door. In case of fire, its fire resistance stability and heat insulation can prevent the spread of fire, slow down the spread of smoke, greatly reduce personal and property losses, win more time for rescue, and save more lives and property safety. Then, what principle is used for fire prevention of fire rolling doors? Now Jinan Rolling Door Factory will analyze it for you.

1.防火卷帘门材质特殊，多层材质。防火卷帘门的布里面有四层，一层是装饰布，二层是耐火布，第三层是防火布，第四层是防辐射布，而假冒伪劣的防火卷帘门则主要有四种，一种是使用不合格的防火材料，二种是偷工减料，比如原本的防火卷帘门需要是四层，但是假冒的防火卷帘门就可能偷工减料到三层。

1. The fireproof rolling door is made of special materials and multi-layer materials. There are four layers of cloth inside the fireproof rolling shutter door. The first layer is decorative cloth, the second layer is fireproof cloth, the third layer is fireproof cloth, the fourth layer is anti radiation cloth, and there are mainly four kinds of fake fireproof rolling shutter doors. One is to use unqualified fireproof materials, and the other is to cut corners. Compared with the original fireproof rolling shutter door, it needs to be four layers, but fake fireproof rolling shutter doors may cut corners to the third layer.

2.防火卷帘门材质不易燃烧性。防火卷帘门里面的材质在煤气灶上也很难被燃烧。说明了它的耐火性。

2. The material of fireproof rolling door is not easy to burn. The material inside the fire shutter door is also difficult to burn on the gas stove. It shows its fire resistance.

3.感应灵敏。防火卷帘门的探测器如果检测到火苗、烟雾，就会接收到信号，使得防火卷帘门先降到一半，感温探测器如果接收到二个信号。防火卷帘门就会全部降下来。这样就可以起到很好的防火隔烟的效果。

3. Sensitive. If the detector of the fire shutter detects flame and smoke, it will receive signals, making the fire shutter door drop to half first, and if the temperature detector receives two signals. The fire shutter doors will all come down. In this way, it can have a good effect of fire and smoke prevention.

此外防火卷帘门有烟和温感的装置设备，在发生火情的时候可以及时的进行分辨和检测，发出警报并采取相关的防火措施，这样可以及时的发现火情，并及时提醒人们控制和防御。

In addition, the fire shutter door is equipped with smoke and temperature sensing devices and equipment, which can timely distinguish and detect when a fire occurs, give an alarm and take relevant fire prevention measures, so that the fire can be found in time and people can be reminded to control and defend in time.
