Fire-proof curtains reach the rise and fall of the curtains through the transmission mechanism and control system. It is fire-proof, fire-proof, product-forming, novel and steel-intensive. Fire-proof curtains, which are widely used in the fire-proof zones of industrial and civilian buildings, can effectively prevent the spread of fires and safeguard life and property and are indispensable fire-proof facilities in modern buildings. It is an active fireproof partition, usually made of metal sheeting, such as steel plates, made up of plugs or entanglements, which are normally rolled up in a rotor box at the door or window, which is dropped during the fire to prevent the fire from spreading through the door or window hole. Fire-proof curtains are necessary for modern buildings and are included in the fire-proof specifications for national buildings and other building designs. The main types are vertical steel curtains, side-to-side fire-proof curtains and flat steel curtains. Extensive use is made of buildings such as hotels, hotels, libraries, cinemas, large malls, stations, underground works and factories, warehouses, garages, etc. Fire-proof curtains are divided by plate type: normal and composite. The general type has a variety of functions, including fire, smoke, wind, rain and piracy. The compound function is the same as the normal, but it is not protected by a water curtain, which is particularly relevant for arid and water-scarce sites。
The selection of an appropriate volume door requires a combination of factors, including use of the environment, needs, budget, operating methods, etc. The following are specific recommendations:
1. Selection based on use of the environment
• humid or corrosive environment: aluminium alloy or stainless steel roll doors are recommended, and such materials are better corrosive。
• fire protection needs: select fire protection sheet doors to ensure effective protection in case of fire。
• temperature control needs: choice of a temperature-conservation curtain to ensure stability of indoor temperature。
2. Choice based on needs
• high demand: places such as banks, jewellery shops, etc., are recommended for the selection of steel or stainless steel curtains with better protection against theft, with electric controls and multiple protective measures。
• general needs: e. G., the commercial pavement, the choice of aluminum alloy curtains to meet the demand is both beautiful and practical。
3. Economic budget choices
• limited budget: manual or ordinary steel curtains can be chosen to meet basic needs without exceeding the budget。
• sufficient budget: it is possible to select an electric roll door with smart features such as remote control, password locks, and to improve accessibility and accessibility。
4. Selection by operational means
• simple operation: it is recommended to select an electric roller door to operate quickly if frequent closing is required。
• low frequency of operations: if not required to operate frequently, it is possible to select manual roll doors, with simple structures and lower prices。
Fast-rolling doors, including fast-rolling doors, fast-rolling doors, fast-rolling showers and aluminium alloy hard fast-rolling doors, are widely used in the medium-sized internal and external sectors, particularly in high-frequency logistics corridors. Its unique aluminum-proof materials and fabric door curtain design are not only robust in appearance but also more capable of bearing heavy loads. In addition, fabric door curtains and window-ready materials can be easily replaced to effectively separate different temperature areas, prevent air convection and ensure indoor constant temperatures, with insect resistance to dust。
Three possible reasons for the failure of the fast-rolling curtain door to recover
1. The gear tank motor lubricated. At this time, new lubricants will need to be replaced to ensure that the electric power is functional。
2. The gap between manual pull rods and gaskets is too wide. In such a case, the gap between the two should be reduced as appropriate to ensure that the manual pull rods can easily pull the curtains。
3. The manual pull of the fast-rolled curtain door is deformed. Once manual pullers are detected, new pullers should be replaced immediately to ensure the proper use of the roll doors。
