Many guests have fire rating requirements when they use these fast rolling shutter doors. They call them fire rolling shutter doors. In fact, there is an essential difference between fire rolling shutter doors and fast rolling shutter doors.

今天富强门业的小编就跟大家说说什么是快速卷帘门，什么是防火卷帘门，这两者之间到底都有哪些不同之处。

Today, the Xiaobian of Fuqiang door industry will tell you what is fast rolling shutter door and what is fire rolling shutter door. What are the differences between the two.

在很多特定场合使用的门是要符合消防要求的，比如厂房通道口，仓库，个车间的交接口出，车间与楼道的接口处，危化品车间等。当火警发生时，防火卷帘门在消防控制系统的控制下，按预先设定的程序自动放下（下行），从而达到阻止火焰向其他范围蔓延的作用，为实施消防灭火争取宝贵的时间，这就是防火卷帘门。

The doors used in many specific occasions should meet the fire protection requirements, such as the access of the plant, the warehouse, the interface of workshops, the interface between workshops and corridors, hazardous chemicals workshop, etc. When a fire alarm occurs, the fireproof rolling shutter door will automatically put down (down) according to the preset procedure under the control of the central fire control system, so as to prevent the spread of flame to other areas and win valuable time for the implementation of fire fighting. This is the fireproof rolling shutter door.

而快速卷帘门的主要功能特点是，保证室内空间里空气环境，室内的温度，湿度达到生产制作的需求，快速卷帘门的快开快关，以及良好的密封性都是为此做保障的，快速卷帘门的多使用在净洁车间，无尘车间，风淋室，货淋室等对于环境要求较高的场合。从使用场地和门的主要功能性上两者都是不同的。

The main functional feature of the fast rolling shutter door is to ensure that the air environment, indoor temperature and humidity in the indoor space meet the needs of production and production, the fast opening and closing of the fast rolling shutter door and good sealing are guaranteed for this. The fast rolling shutter door is mostly used in clean workshop, dust-free workshop, air shower room, cargo shower room and other occasions with high environmental requirements. Both are different in terms of the use site and the main functions of the door.

为什么人们会把快速门和防火门两者混淆呢？其根本原因还是在防火上，因为快速卷帘门的门帘是具备阻燃功能的，工业聚酯纤维基布是阻燃的，阻燃就是在有明火是会燃烧，本身不会自燃，明火灭自熄；而防火卷帘门的门帘是具备消防要求的防火材质，是不会燃烧的可以阻止火势的蔓延。但是防火卷帘门的开关门速度比较慢，平时都是在常开的状态，只有当火情发生时门帘才会自动降落。很多客人在咨询快速卷帘门的时候又想让门能够满足快开快关的要求又想到达防火的等级要求，这是不正确的，有明文的防火证明资质的只有防火卷帘门，而快速卷帘门是不能开具防火证明的，它只是净洁门，一种保温保冷，密封防尘的快速卷帘门。

Why do people confuse fast doors with fire doors? The fundamental reason is fire prevention, because the curtain of the fast rolling shutter door has flame retardant function, and the industrial polyester fiber base cloth is flame retardant. Flame retardant means that it will burn when there is an open fire, and it will not spontaneous combustion, and the open fire will extinguish itself; The curtain of fireproof rolling shutter door is a fireproof material with national fire control requirements, which will not burn and can prevent the spread of fire. However, the opening and closing speed of the fireproof rolling shutter door is relatively slow. It is usually in the normally open state. Only when a fire occurs, the curtain will automatically fall. When consulting the fast rolling shutter door, many guests want the door to meet the requirements of fast opening and fast closing, and also want to reach the fire rating requirements. This is not correct. Only the fire rolling shutter door with written fire proof qualification can be issued, but the fast rolling shutter door can not issue fire proof certificate. It is just a clean door, an environmental protection fast rolling shutter door with thermal insulation, cold insulation, sealing and dust prevention.
