Fire shutter door is generally considered as a kind of shutter door, but in essence our fire shutter door is a kind of fire, smoke and heat insulation effect. This is an indispensable fire protection facility for large building openings.

防火卷帘门设置一套专用的消防系统。当火灾发生时，烟雾探测器和温度探测器将接收信号来触发消防系统。此时，防火卷帘门将充分发挥其防火、防烟性能。有效防止火灾蔓延，为消防队员获得宝贵的救援时间，从而大大减少人身生命财产损失。

The fire shutter door is equipped with a special central fire control system. When a fire occurs, smoke detectors and temperature detectors will receive signals to trigger the fire protection system. At this time, the fire shutter door will give full play to its fire and smoke performance. It can effectively prevent the spread of fire, provide valuable rescue time for firefighters, and greatly reduce the loss of life and property.

工作过程：开门传感器向控制系统提供触发信号，控制系统根据快速卷门的当前位置向变频器发出指令，启动驱动电机使门帘快速上升，车辆和行人通过后门帘自动下降，关闭通道，直到下一次开门信号再次打开。顾名思义，快卷门的垂直速度很快，不能像卷钢门那样直接启停。通常，需要变频器来控制电机的速度。尽快到位(20cm左右)，要有一个减速、缓冲、停车的过程，防止轨道被撞，防止人被抓，减少噪音，这也是衡量快卷门性能的标准。

Working process: the door opening sensor provides the trigger signal to the control system, and the control system sends the command to the frequency converter according to the current position of the fast rolling door, starts the driving motor to make the curtain rise rapidly, and the vehicles and pedestrians automatically drop through the rear curtain to close the channel until the next door opening signal is opened again. As the name suggests, the vertical speed of the fast rolling door is very fast, and it can't be directly started and stopped like the rolling steel door. Usually, a frequency converter is needed to control the speed of the motor. As soon as possible (about 20cm), there should be a deceleration, buffering, parking process, to prevent the track from being hit, to prevent people from being caught, to reduce noise, which is also the standard to measure the performance of the fast rolling door.

门布材质：门帘布一般采用PVC或PVDF薄膜，特别是PVDF薄膜抗老化性能更好，不易褪色，具有自清洁功能，非常适合做快卷门。

Door cloth material: curtain cloth usually adopts PVC or PVDF film, especially PVDF film has better anti-aging performance, and is not easy to fade. It has self-cleaning function and is very suitable for quick roll door.

防火门制造商，他们的主要产品是防火门，但他们不仅仅生产这些。但是我们可以先说防火门。防火门的主要用途是防火，但它们是由各种材料制成的，如钢和木材。消费者需求多样化，所以厂商生产多样化，每个人都有更多的选择。他们可以根据自己的喜好选择各种材质的防火门。

买防火门的时候，不要忽略一个窗户的选择，这样可以更好的保护家人。除了门窗，有些工厂的门可能是卷的。工厂的防火很重要，虽然大多数卷帘都是钢铁制成的。但是这种材料并不代表它有很强的耐火性，我们应该看看防火门厂家生产的专用防火卷帘。

When you buy fire doors, don't ignore the choice of a window, which can better protect your family. In addition to doors and windows, some factory doors may be rolled. Fire prevention in factories is very important, although most of the rolling shutters are made of steel.
