Welcome to inquire! Contact: Weijing Li. When selecting fire shutter doors most important factor is the fire resistance of fire shutter doors. There are two methods of fire shutter fire resistance: one fire shutter in accordance with existing national standards GB7633 "fire test methods door and shutter" in Taiyuan glass fire door fire resistance test, including the unexposed surface temperature rise, including all Item condition judging judgment; the second is the same fire resistance test carried out in accordance with GB7633, according to the standard non-insulated protective layer on metal shutter waiver provisions unexposed surface temperature and product standards "steel fire shutter general technical conditions" (GB14102-93) requirements Taiyuan fire doors, fire back surface only to a certain distance away from the radiant heat intensity and curtain side wear fire to determine whether the fire resistance of rolling shutter. According to fire back surface temperature rise does not include the fire resistance of determining conditions for non-insulated fire shutter, fire resistance of the resulting data, including the unexposed surface temperature than the fire resistance of determining conditions for thermal insulation fire shutter fire resistance to be much longer. Fire shutter is based on steel shutter on and will be transmission components transformation, with fire appliances and other equipment, in order to achieve fire effects: fire the motor by fire electrical control box control, through transmission driving the reel so that the shutter doors from closing, power outages When can also be used to manually crank on the motor Shanxi fire wood fire doors, manual operation can be realized. In the relative motion of the mechanical, instead of using coupling sprocket, rail friction inlaid copper or nylon. Best suited for use or storage of flammable gas, and other volatile chemicals and other items with high pyrophoric factories and warehouses or may occur fire explosion hazardous environments.
