The fire shutter door is a kind of fireproof and heat insulation device suitable for large openings of buildings, which can effectively prevent the spread of fire and ensure the safety of life and property. For such products, quality is naturally guaranteed. Today we come to a good exploration of the fire shutter door specifications . The requirements for the production of fire shutter doors and fire shutter doors are relatively high, that is, the entire system is required to withstand the high temperature test of about 1100° for a certain period of time. The fireproof time of fire shutter doors is the main indicator of fire shutter doors. GB14102-93 steel fire shutter doors in the general technical conditions for fire-resistant time for the four fire rating. There are no national standards for the fire shutter doors specifications , fire rating of fire shutters, GB14102 "General technical conditions for steel fire shutters" will be ordinary steel fire shutter is divided into: But now the implementation of the standard is GB14102-2008 "fire "Curtain" standard. Grade 1, fire time 1.50h; F2 grade, fire time 2.0h. Fire shutter doors specifications 3 , according to the test method will be divided into two types of fire shutters, namely: ordinary fire shutter and special fire shutter. Ordinary fire shutters are not judged by the temperature rise of the backfire surface. When the fire endurance limit is not less than 3h, the requirements for insulation and fireproof separation can be met; while the special fireproof roller blind is judged by the temperature rise of the backfire surface, when the fireproof limit is reached. When it is not less than 3 hours, it has the heat insulation function and can meet the requirements of fire partition separation. Fireproof rolling door specifications 4 , specifications (such as GB50045-95 "high-rise civil building design fire protection specifications") or designed specifically for fire, smoke partition wall door. For example, the equipment room (cylinder room, foam station, etc.) of the fixed fire extinguishing device attached to the high-rise civil buildings, the partition wall door of the ventilation and air-conditioning room, etc. shall be Class A fire doors; often people stay or have more combustible materials. Doors on the partition walls of basements shall be Class A fire doors. Due to conditions, high-rise buildings must be equipped with fuel and gas boilers, fuel-oil-immersed power transformers, high-voltage capacitors and switches filled with fuel, etc., and doors on dedicated room partition walls should be Class A fire doors. . There are separate doors for fire protection that are specially designed, such as the fire control monitoring center, archives room, valuables warehouse, etc., which usually use Class A or Class B fire doors. The fireproofing door standard 5 and national standard GB14102 grading the fireproof performance of steel fireproof rolling shutter doors, and no fireproof test is required to measure the temperature rise of the backfire surface, and the temperature of the backfire surface is not used as the condition for determining the fireproof time, which has appeared in the market in recent years. Steam-blown steel fire-retardant roller shutters, evaporative steam-mould steel fire-retardant roller blinds, etc., shall comply with the requirements of the "High Regulations". When used as a partition for fire protection partitions, the temperature rise of the backfire surface must be considered as the fire-resistant limit. condition. In order to distinguish the fireproof roller shutter grades of fire resistance limit between the above two different judgment conditions, before the national standard of fire blind roller classification was issued, the experts of “High Regulations†management suggested that the fire resistance test of the doors and shutters be according to national standards. Method "GB7633 fire test, to achieve the requirements including the temperature of the back surface of the fire in the determination of the conditions, the fire-resistant limit ≥ 3.0h, known as the special fire shutter, where in the fire test is not to determine the temperature rise of the back surface The conditions are collectively referred to as ordinary fire shutter doors. About the fire shutter door specifications introduced to this, I hope to help you. The most important factor when choosing a fire shutter door is the fire end of the fire shutter door. Everyone must be careful. If you still want to learn more about the fire shutter doors, please pay attention to the website decoration information channel.
