Central Air Conditioning Smoke Protection Rock Wool Board

The special fire-resistant rock wool series for smoke control and exhaust ducts is a core protective material specially developed and accurately adapted to the fire protection needs of building smoke control and exhaust systems. With high-quality rock wool as the base material, this series of products has been processed and modified by special technology, featuring excellent thermal stability, outstanding high-temperature resistance and strong anti-shrinkage capacity, building a solid fire protection line for the smoke control and exhaust system from the material level. In the event of a fire, even when exposed to continuous high-temperature baking, the product can effectively resist high-temperature erosion, avoid self-shrinkage and deformation, firmly maintain the structural integrity and airtightness of the smoke control and exhaust ducts, ensure the stable operation of the smoke control and exhaust system, open a safe and unobstructed escape route for the trapped personnel in the building, and minimize the life threat caused by fire smoke.

The smoke control and exhaust system is an important part of the building fire protection system, which is mainly divided into two modules: the smoke prevention system and the smoke exhaust system. The two modules operate synergistically and complement each other to jointly realize smoke control in fire scenarios. The system is usually composed of core equipment such as exhaust ducts, pipe shafts, fire dampers, door switch equipment, supply fans, and exhaust fans. Each equipment performs its own duties and cooperates closely to ensure the efficient operation of the overall function of the system. Among them, the exhaust ducts and pipe shafts, as the core carriers for smoke transmission, are responsible for guiding the smoke to the designated area in an orderly manner; the fire damper, as a key fire separation component, can automatically close in the event of a fire to block the spread of smoke; the door switch equipment cooperates with the supply and exhaust fans to accurately control the direction and intensity of air flow, ensuring the smoke exhaust and smoke prevention effect of the system.

In the sudden fire scenario, the stable operation of the smoke control and exhaust system is the key to ensuring the life safety of personnel and gaining time for emergency rescue. Among them, the smoke prevention system continuously delivers fresh air to core evacuation areas such as stairwells and anterooms through the continuous operation of high-power positive pressure supply fans, making these areas form a positive pressure environment, effectively preventing toxic and harmful smoke generated by the fire from entering, and providing a relatively safe evacuation space for trapped personnel; the smoke exhaust system, through the strong suction effect of the exhaust fan, timely discharges a large amount of thick smoke and toxic gases generated in the building to the outside, reduces the indoor smoke concentration, reduces the risk of suffocation and poisoning of trapped personnel by smoke, and at the same time improves the visibility of the fire scene, creating favorable conditions for fire rescue personnel to carry out rescue work and gaining valuable time for personnel safety evacuation and emergency disposal.
