    防火卷帘门挑选是一个技术活
    Fire shutter door selection is a technical activity.
    防火卷帘门效果是要能起到防火的效果.但是现在许多厂家都为了节省本钱偷工减料,如果在有火灾的情况下达不到好的防火效果而造成了丢失.我们怎么挑选一个好的防火卷帘门,济南防火卷帘门厂家告诉您,只需知道一下这四个常识就可以了.
    Fire-proof rolling shutter door effect is to play a fire-proof effect. But now many manufacturers in order to save money jerry-built materials, if there is a fire situation can not achieve good fire-proof effect and caused loss. How do we choose a good fire-proof rolling shutter door, Jinan fire-proof rolling shutter door manufacturers tell you, just know these four often Knowledge is fine.
    防火卷帘门门帘厚度

    谁也能想到要看门帘的厚度啦,就是帘板所用钢板的厚度,现在遍及存在着偷工减料现象,许多厂家送交测验时用较厚钢板的帘板,获得合格证后就改用较薄的进行生产.因为在装置现场卷帘门的帘板厚度不易丈量,容易过关,因此有许多防火卷帘门,因门帘厚度都未达到要求,削减运用寿命与耐火时限,所以我们要擦亮你的火眼金睛,看好细节.

    Anyone can imagine to see the thickness of the door curtain, that is, the thickness of the steel plate used in the curtain board, now there is a phenomenon of jerry-built cutting, many manufacturers submit the test with a thicker steel plate curtain board, after obtaining a certificate of conformity to use a thinner production. Multi-fireproof rolling shutter door, because the thickness of the curtain has not met the requirements, reducing the use of life and fire-resistant time limit, so we want to polish your eyes, good details.

    要注意的是看防火卷帘门门帘有没有底梁.
    What we should pay attention to is to see whether there are any bottom beams on the fire shutter doors.
    要看防火卷帘门的导轨了.卷帘门导轨深度不够,结构与用料不当是大型卷帘门装置中遍及存在的问题.在大型门导轨上应有一根能承受主构件,但是许多厂商用简易的轻型导轨来替代.如遇到火灾,门帘易从导轨脱出,起不到防火效果.
    It is necessary to look at the guide rail of the fire-proof rolling shutter door.The depth of the guide rail of the rolling shutter door is not enough,and the structure and materials are improper.There should be a main component that can bear on the guide rail of the large-scale rolling shutter door.But many manufacturers replace it with simple light guide rail.In case of fire,the door curtain is easy to get out of the guide rail,so the fire-proof effect can not be achieved.

    防火卷帘门门楣结构及防烟.按国标规范防火卷帘门须设置门楣结构.现在遍及运用的是没有门楣的防火卷帘门,火灾中阻止不了火势向上构成的冲击,烟气经过门楣向外延伸.所以门楣处的密封性是防火、防烟的关键所在,若装置没有门楣结构的防火卷帘门,则形同虚设.
    Fire curtain lintel structure and smoke prevention. Fire curtain doors must be equipped with lintel structure according to national standard. Fire curtain doors without lintel are widely used nowadays. Fire can not prevent upward impact of fire. Smoke extends outward through lintel. So the sealing of lintel is the key to fire prevention and smoke prevention, if the device is not installed. The fire shutter doors with lintel structure are in name only.
