Overview

Fireproof bag - Fire retardant bag is a new type of fire-resistant material developed by our company according to the national standard GB23864-2009. The outer layer of the fire-resistant bag (fire retardant bag) is made of tightly woven and specially treated durable glass fiber cloth in a bag shape, and the interior is filled with special fire-resistant, thermal insulation materials and expansion materials. This product has good ventilation and breathability, acid and alkali resistance, water resistance, oil resistance, light weight, and easy use at room temperature. When exposed to fire, it rapidly expands and carbonizes to form a fire-resistant barrier with a certain thickness and strength. During the expansion and carbonization process, it absorbs heat and releases non combustible gases, achieving the purpose of fire-resistant, thermal insulation, and smoke isolation. It is an ideal product for fire prevention and flame retardancy of power cable facilities.

Product Details

Fireproof bags (fire-resistant bags) have non flammability, with a fire resistance time of more than 4 hours, and can expand and solidify at higher temperatures. Form a heat-insulating and smoke proof seal, with good fire and moisture resistance, and free of toxic substances such as asbestos.

　　Purpose:

Suitable for sealing voids formed when cables, oil pipes, air ducts, gas pipes, metal pipes, and other penetrating objects pass through partition walls or compartments in power, telecommunications, postal, chemical, industrial and mining, enterprise, and construction industries.

Our company's product performance has reached the advanced level of similar foreign products. The fireproof package (fire-resistant package) can be used for fireproof sealing at cable penetration holes in power plants, industrial and mining enterprises, high-rise buildings, petrochemicals, etc. It is particularly suitable for occasions where cables need to be replaced or added frequently, or for temporary fire prevention measures in construction projects.

　　Construction method:

Cable shafts are supported by fire-resistant nets, fire-resistant plates, and fire-resistant iron plates. Fireproof packages are laid flat on the pads and stacked into compartments. Cable tunnels and cable trenches are designed according to the relevant spacing regulations for cable tunnels and cable shafts in China. At locations where partition walls need to be installed, fire-resistant packages can be stacked into firewalls. If necessary, angle steel can be used to make brackets for easy sealing.
