The outer layer of the fire bag is made of tightly woven, specially treated and durable glass fiber cloth, and the interior is filled with special fire-resistant, heat insulation materials and expansion materials. The fire bag is non combustible, with a fire resistance limit of more than 4 hours, and expands and solidifies at a higher temperature.
It forms a heat insulation and smoke-proof seal, has good fire and moisture resistance, and does not contain toxic components such as asbestos. The main technical performance has reached the advanced level of similar foreign products. The fire bag can be effectively used for fire blocking at the cable penetration holes of power plants, industrial and mining enterprises, high-rise buildings and petrochemical enterprises, especially for occasions where cables need to be replaced or increased frequently or temporary fire prevention measures in construction projects.
Application:
It is suitable for plugging holes formed when penetrations such as cables, oil pipes, air ducts, gas pipes and metal pipes pass through partition walls or partitions in power, telecommunications, postal, chemical, industrial and mining, enterprises and buildings. It can prevent flame spread, especially suitable for important parts of cables that are often replaced. It can effectively prevent the fire from burning and spreading along the cable and avoid the loss of life and property to the greatest extent. The product has the characteristics of good ventilation and permeability, acid and alkali resistance, water resistance, oil resistance, light weight and convenient use at room temperature. It expands and carbonizes rapidly in case of fire to form a fire barrier with certain thickness and strength, absorbs heat and releases non combustible gas in the process of expansion and carbonization, so as to achieve the purpose of fire resistance, heat insulation and smoke separation. It is an ideal product for fire prevention and flame retardant of power cable facilities.
