Nowadays, on the market of fire shutter doors, steel fire shutter doors and inorganic fabric fire shutter doors are two very common fire shutter doors products. Compared with steel fire shutter doors, there are more places for the use of super class fire shutter doors, which is determined by the superior performance of fire resistant rolling shutters. Today, Ji'nan rolling door manufacturers introduce the advantages and disadvantages of inorganic fabric fire shutter door.
1, high fire resistance. When the temperature of the back fire surface is used as the criterion of fire resistance, the fire resistance of the fireproof door is usually less than 3 hours. The performance of the inorganic special fire roll curtain can not be compared with the steel fire curtain. The composite steel fire curtain may reach more than 3 hours of fire resistance, but it is determined by the measurement of its thermal radiation intensity. If it is judged by the temperature rise of the back fire surface, the steel composite fire curtain door can not reach more than 3 hours. Time requirements.
2, the structure is superior.
The inorganic cloth fire curtain is a double rail double curtain structure. There is a certain thickness of air layer between the two layers of curtain, and the two door curtain rises and falls synchronously. In order to resist negative pressure, the steel strip is reinforced at both ends of the guide rail, and the "T" structure is added in the clearance to prevent the appearance of the curtain from falling from the guide rail. .
3. Good heat insulation.
The installation of fireproof curtain of inorganic cloth completely meets the requirements, without water protection and good heat insulation. It is a new super class fire shutter door product.
