濟南卷簾門要達到防火要求，需從材料、結構、配件到工藝進行設計，形成完整的防火體系，才能在火災發生時有效阻隔火勢蔓延，為人員疏散和滅火救援爭取時間。

　　Jinan rolling shutter doors need to meet fire prevention requirements through comprehensive design from materials, structures, accessories to processes, forming a complete fire prevention system, in order to effectively block the spread of fire in the event of a fire, and buy time for personnel evacuation and firefighting rescue.

　　防火材料的選擇是基礎保障。簾面需采用耐高溫的復合板材，常見的有鋼質防火卷簾（簾面厚度不小于 0.8 毫米），內部填充防火隔熱材料（如硅酸鋁纖維毯，耐火極限需達 3 小時以上），這種材料在高溫下不熔融、不釋放有毒氣體，能承受 800℃以上的火焰直接灼燒。簾面表層需經特殊處理，添加防火涂料（如膨脹型防火涂料，涂層厚度不小于 1.5 毫米），遇火時涂料膨脹形成蜂窩狀隔熱層，進一步延緩熱量傳遞。與普通卷簾門的塑料或普通鋼材相比，防火卷簾門的材料成本雖增加 50% 以上，但能在關鍵時候阻止火勢穿透。

　　The selection of fire-resistant materials is a fundamental guarantee. The curtain surface should be made of high-temperature resistant composite panels, commonly including steel fireproof rolling shutters (curtain thickness not less than 0.8 millimeters), filled with fireproof insulation materials (such as aluminum silicate fiber blankets, with a fire resistance limit of more than 3 hours). This material does not melt or release toxic gases at high temperatures and can withstand direct burning from flames above 800 ℃. The surface layer of the curtain needs to be specially treated by adding fireproof coating (such as expansion fireproof coating, with a coating thickness of not less than 1.5 millimeters). When exposed to fire, the coating expands to form a honeycomb insulation layer, further delaying heat transfer. Compared with ordinary plastic or steel rolling shutter doors, the material cost of fireproof rolling shutter doors increases by more than 50%, but it can prevent fire from penetrating in critical situations.

　　結構設計需滿足密封與抗變形要求。簾面之間的拼接處需采用防火密封條（多為石墨膨脹條），當溫度達到 200℃時自動膨脹，填充縫隙，阻止煙氣滲透。導軌與墻體連接部位需用防火水泥砂漿封堵，避免火焰從縫隙竄出，縫隙寬度需控制在 3 毫米以內，且每米長度的錨固點不少于 3 個，確保高溫下不會松動脫落。簾面的卷軸和導軌需選用加厚鋼材（厚度不小于 3 毫米），經高溫時效處理內應力，防止火災中因受熱不均產生變形，保證卷簾門能正常啟閉。對于高度超過 6 米的大型防火卷簾門，需在中間增設水平防火封堵條，將整體分割為多個區域，降低單塊簾面的受熱變形風險。

　　The structural design must meet the requirements of sealing and deformation resistance. Fireproof sealing strips (mostly graphite expansion strips) should be used at the joints between the curtain surfaces. When the temperature reaches 200 ℃, they will automatically expand, fill the gaps, and prevent smoke from penetrating. The connection between the guide rail and the wall should be sealed with fireproof cement mortar to prevent flames from escaping through the gap. The gap width should be controlled within 3 millimeters, and there should be no less than 3 anchoring points per meter length to ensure that it will not loosen or fall off under high temperature. The roller and guide rail of the curtain surface need to be made of thickened steel (with a thickness of not less than 3 millimeters), which has undergone high-temperature aging treatment to eliminate internal stress, prevent deformation due to uneven heating in a fire, and ensure the normal opening and closing of the rolling shutter door. For large fireproof rolling shutter doors with a height exceeding 6 meters, a horizontal fireproof sealing strip should be added in the middle to divide the whole into multiple areas and reduce the risk of thermal deformation of a single curtain surface.

　　防火配件是功能實現的關鍵。驅動系統需配備防火電機，采用耐高溫繞組線圈，能在 300℃環境下正常工作 30 分鐘以上，且具備斷電自動下降功能（通過備用電源或重力平衡裝置），確保火災時即使斷電，卷簾門也能自動關閉。控制箱需安裝溫度感應裝置（如易熔合金探測器，熔斷溫度設定為 70℃），當探測到環境溫度超標時，自動觸發卷簾門下降，響應時間不超過 10 秒。此外，需設置手動應急操作裝置，在電機失效時，通過鏈條或手搖柄手動關閉卷簾門，操作力不超過 150N，確保緊急情況下任何人都能快速操作。

　　Fireproof accessories are the key to achieving functionality. The drive system needs to be equipped with a fire-resistant motor, using high-temperature resistant winding coils, capable of working normally for more than 30 minutes in an environment of 300 ℃, and equipped with automatic descent function (through backup power supply or gravity balance device) to ensure that the rolling shutter door can automatically close even if the power is cut off in case of a fire. The control box needs to be equipped with a temperature sensing device (such as a fusible alloy detector with a melting temperature set at 70 ℃). When the ambient temperature exceeds the standard, it will automatically trigger the rolling shutter door to descend, with a response time of no more than 10 seconds. In addition, a manual emergency operation device should be installed to manually close the rolling shutter door through a chain or hand crank in case of motor failure, with an operating force not exceeding 150N, ensuring that anyone can operate quickly in emergency situations.

　　防火性能需通過嚴格測試驗證。濟南的防火卷簾門需符合相關防火標準，經耐火試驗檢測 —— 在模擬火災環境中（溫度按標準曲線升高，1 小時達到 925℃），卷簾門需保持 30 分鐘以上的完整性（無火焰穿透）和隔熱性（背火面平均溫度不超過 140℃，溫度不超過 180℃）。測試中還需驗證卷簾門的啟閉功能，在經歷高溫灼燒后，仍能正常開啟和關閉少 3 次，避免因變形卡滯導致無法疏散。通過測試的產品需具備相應的防火認證標識，才能在、廠房等人員密集場所使用。

　　The fire resistance performance needs to be verified through rigorous testing. The fire-resistant rolling shutter doors in Jinan must comply with relevant fire safety standards and undergo fire resistance testing. In a simulated fire environment (where the temperature rises according to the standard curve and reaches 925 ℃ in 1 hour), the rolling shutter doors must maintain integrity (no flame penetration) and thermal insulation for more than 30 minutes (the average temperature of the back fire surface should not exceed 140 ℃, and the maximum temperature should not exceed 180 ℃). In the test, it is necessary to verify the opening and closing function of the rolling shutter door. After experiencing high temperature burning, it can still be opened and closed normally at least 3 times to avoid being unable to evacuate due to deformation and jamming. Products that have passed the test must have corresponding fire certification marks before they can be used in crowded places such as shopping malls and factories.

　　安裝與維護保障長期防火效果。安裝時需保證卷簾門與建筑結構的固定牢固，門框與墻體之間的縫隙用防火密封膠填充，固化后形成連續密封層。每年需進行少 1 次維護保養，包括清理導軌內的雜物、檢查密封條的完整性、測試電機和溫控裝置的靈敏度，確保各部件處于正常狀態。對于使用超過 5 年的防火卷簾門，需抽樣進行耐火性能復測，更換老化的密封條和電機部件，避免因材料老化導致防火性能下降。

　　Installation and maintenance ensure long-term fire prevention effectiveness. During installation, it is necessary to ensure that the rolling shutter door is firmly fixed to the building structure. The gap between the door frame and the wall should be filled with fireproof sealant, and a continuous sealing layer should be formed after curing. At least one maintenance should be carried out annually, including cleaning debris inside the guide rail, checking the integrity of the sealing strip, testing the sensitivity of the motor and temperature control device to ensure that all components are in normal condition. For fire-resistant rolling shutter doors that have been in use for more than 5 years, it is necessary to sample and retest their fire resistance performance, replace aging sealing strips and motor components, and avoid a decrease in fire resistance performance due to material aging.
