防火卷帘门是现代建筑防火体系中不可或缺的设施，已列入国家建筑及其他建筑设计防火规范。它广泛应用于出色宾馆、饭店、图书馆、影剧院、大型商场、车站、地下工程及工厂厂房、仓库、车库等建筑。防火卷帘门在平时卷起在门窗上口的转轴箱中，起火时将其放下展开，用以阻止火势从门窗洞口蔓延。

Fireproof rolling shutter doors are indispensable facilities in modern building fire prevention systems and have been included in national building and other building design fire prevention regulations. It is widely used in high-end hotels, restaurants, libraries, cinemas, large shopping malls, stations, underground engineering, factories, warehouses, garages and other buildings. The fireproof rolling shutter door is usually rolled up in the pivot box at the top of the door and window, and when it catches fire, it is lowered and unfolded to prevent the fire from spreading through the door and window openings.

防火卷帘按照材质分为钢质防火卷帘和无机纤维复合防火卷帘。钢质防火卷帘是用钢质材料做帘板、导轨、座板、门楣、箱体等，并配以卷门机和控制箱；无机纤维复合防火卷帘则是用无机纤维材料做帘面（内配不锈钢丝或不锈钢丝绳），用钢质材料做夹板、导轨、座板等。

Fireproof rolling shutters are divided into steel fireproof rolling shutters and inorganic fiber composite fireproof rolling shutters according to their materials. Steel fireproof rolling shutter is made of steel materials for the curtain board, guide rail, seat board, lintel, box body, etc., and is equipped with a rolling door machine and control box; Inorganic fiber composite fireproof rolling shutter is made of inorganic fiber material for the curtain surface (with stainless steel wire or stainless steel wire rope inside), and steel material for the clamp plate, guide rail, seat plate, etc.

在耐火性能方面，根据GB14102《钢质卷帘通用技术条件》，普通钢质卷帘分为F1级（耐火时间1.50h）和F2级（耐火时间2.0h）；复合型钢质卷帘分为F3级（耐火时间2.50h）和F4级（耐火时间3.00h）。耐火出色≥3.0h的称为特级卷帘。

In terms of fire resistance, according to GB14102 "General Technical Conditions for Steel Rolling Shutters", ordinary steel rolling shutters are divided into F1 level (fire resistance time 1.50h) and F2 level (fire resistance time 2.0h); Composite steel roller blinds are divided into F3 grade (fire resistance time 2.50h) and F4 grade (fire resistance time 3.00h). A roller shutter with a fire resistance limit of ≥ 3.0 hours is called a special grade roller shutter.

防火卷帘的设置有着严格的规范要求。当防火分隔部位的宽度不大于30m时，防火卷帘的宽度不应大于10m；当防火分隔部位的宽度大于30m时，防火卷帘的宽度不应大于该部位宽度的1/3，且不应大于20m。防火卷帘应具有火灾时靠自重自动关闭功能。2024年，国家发布了《防火卷帘》系列强制性国家标准（GB 14102.1-2024、GB 14102.2-2024等），对防火卷帘的材料、零部件、装配质量和运行性能进行了补充和完善，将于2025年5月1日正式实施。

The installation of fireproof rolling shutters has strict regulatory requirements. When the width of the fireproof partition is not greater than 30m, the width of the fireproof rolling shutter should not be greater than 10m; when the width of the fireproof partition is greater than 30m, the width of the fireproof rolling shutter should not be greater than one-third of the width of that part, and should not be greater than 20m. The fireproof rolling shutter should have the function of automatically closing by its own weight in case of fire. In 2024, the country issued a series of mandatory national standards for fireproof rolling shutters (GB 14102.1-2024, GB 14102.2-2024, etc.), which supplemented and improved the materials, components, assembly quality, and operational performance of fireproof rolling shutters. They will be officially implemented on May 1, 2025.

电动卷帘门：电机是“心脏”

Electric rolling shutter door: motor is the "heart"

电动卷帘门是以多关节活动的门片串联在一起，起动由电动机组带动，在固定的滑道内以门上方卷轴为中心转动上下的门。它适用于商业门面、车库、商场、医院、厂矿企业等公共场所或住宅，尤其是门洞较大、不便安装地面门体的地方。

Electric rolling shutter door is a series connection of multi joint movable door panels, which are driven by an electric motor group to rotate up and down the door around the scroll above the door in a fixed sliding track. It is suitable for public places or residences such as commercial storefronts, garages, shopping malls, hospitals, factories and mines, especially for places with large door openings and inconvenient installation of ground doors.

电动卷帘门的核心在于专用电机。卷帘门专用电机主要有：防火卷门机、澳式卷门机、外挂卷门机、管状卷门机、无机双帘卷门机、快速卷门机等。采用不同专用电机的电动卷帘门各有特点。其中，防火卷门机具有防火功能，能在火灾发生时自动关闭卷帘门，阻止火势蔓延；管状卷门机电机呈管状结构，体积小，适合安装在空间有限的场所。

The core of an electric rolling shutter door lies in a dedicated motor. The specialized motors for rolling shutter doors mainly include: fireproof rolling shutter door machine, Australian rolling shutter door machine, external rolling shutter door machine, tubular rolling shutter door machine, inorganic double curtain rolling shutter door machine, fast rolling shutter door machine, etc. Electric rolling shutter doors with different specialized motors have their own characteristics. Among them, the fireproof rolling door machine has a fireproof function, which can automatically close the rolling shutter door in case of a fire, preventing the spread of fire; The motor of the tubular rolling door machine has a tubular structure, small volume, and is suitable for installation in places with limited space.

在控制系统方面，电动卷帘门可通过遥控器实现上升、停止、下降等动作。绝大多数电动卷帘门配备的是微波射频遥控器。部分出色产品还配备智能红外线双探头防碰撞装置，遇人或异物20cm范围内即可自动停止或反弹，确保使用安全。

In terms of control system, the electric rolling shutter door can achieve actions such as rising, stopping, and falling through a remote control. The vast majority of electric rolling shutter doors are equipped with microwave and radio frequency remote controls. Some high-end products are also equipped with intelligent infrared dual probe anti-collision devices, which can automatically stop or rebound within a 20cm range when encountering people or foreign objects, ensuring safe use.
