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.

防火卷簾門設置一套專用的消防系統。當火災發生時，煙霧探測器和溫度探測器將接收信號來觸發消防系統。此時，防火卷簾門將充分發揮其防火、防煙性能。有效防止火災蔓延，為消防隊員獲得寶貴的救援時間，從而大大減少人身生命財產損失。

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.

工作過程：開門傳感器向控制系統提供觸發信號，控制系統根據快速卷門的當前位置向變頻器發出指令，啟動驅動電機使門簾快速上升，車輛和行人通過后門簾自動下降，關閉通道，直到下一次開門信號再次打開。顧名思義，快卷門的垂直速度很快，不能像卷鋼門那樣直接啟停。通常，需要變頻器來控制電機的速度。盡快到位(20cm左右)，要有一個減速、緩沖、停車的過程，防止軌道被撞，防止人被抓，減少噪音，這也是衡量快卷門性能的標準。

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.

門布材質：門簾布一般采用PVC或PVDF薄膜，特別是PVDF薄膜抗老化性能更好，不易褪色，具有自清潔功能，非常適合做快卷門。

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.

防火門制造商，他們的主要產品是防火門，但他們不僅僅生產這些。但是我們可以先說防火門。防火門的主要用途是防火，但它們是由各種材料制成的，如鋼和木材。消費者需求多樣化，所以廠商生產多樣化，每個人都有更多的選擇。他們可以根據自己的喜好選擇各種材質的防火門。

Fire door manufacturers, their main products are fire doors, but they don't just produce these. But we can start with fire doors. The main purpose of fire doors is to prevent fire, but they are made of various materials, such as steel and wood. Consumer demand is diversified, so manufacturers are diversified, and everyone has more choices. They can choose fire doors of various materials according to their own preferences.

除了生產防火門，防火門制造商還會生產一些其他的消防產品，比如窗戶。窗戶也是防火過程中非常重要的一件事。我們不僅要注意門，還要注意窗戶。所以這些廠家也會生產防火窗，可以讓大家都待在更的環境里。

In addition to the production of fire doors, fire door manufacturers will also produce some other fire products, such as windows. Windows are also very important in the process of fire prevention. We should pay attention not only to the door, but also to the window. So these manufacturers will also produce fire windows, so that everyone can stay in a safer environment.

買防火門的時候，不要忽略一個窗戶的選擇，這樣可以更好的保護家人。除了門窗，有些工廠的門可能是卷的。工廠的防火很重要，雖然大多數卷簾都是鋼鐵制成的。但是這種材料并不代表它有很強的耐火性，我們應該看看防火門廠家生產的專用防火卷簾。

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. But this material does not mean that it has a strong fire resistance, we should take a look at the fire door manufacturers dedicated fire shutter.

防火卷簾可以更好地保護工廠免受火災。即使發生火災，也不會到處蔓延，造成更大的損失。

Fire shutter can better protect the factory from fire. Even if there is a fire, it will not spread everywhere, causing greater losses.
