Do you know about fire protection package?

The outer layer of the fireproof package is made of a tightly-woven, glass fiber cloth that is specially processed and durable to form a bag shape. The interior is filled with special fire-resistant, heat-insulating materials and intumescent materials. The fireproof package has incombustibility, and the fire-resistant limit can reach over 4 hours. It swells and solidifies at high temperatures. It forms a heat-insulating, smoke-proof seal, and is fire-proof and moisture-resistant, and does not contain toxic components such as asbestos. The main technical performance has reached the advanced level of foreign products of the same type. The fireproof package can be effectively used for the fireproof plugging of power cables, industrial and mining enterprises, high-rise buildings, petrochemicals and other cable through-holes, and is particularly suitable for the need for frequent replacement or increase or decrease of cables. Temporary fire prevention measures in the occasion or construction project.

Fire protection principle:

Fireproof package is a new type of fireproof refractories developed by our company according to the GB23864-2009 national standard. This product can be made into various shapes of firewalls and fireproof layers according to the requirements of users. It can also block the holes required for fireproof treatment. . In the event of a fire, the material in the fireproof package expands by heat and forms a honeycomb monolith, effectively controlling the fire within a localized area.


Fire protection package manufacturer product use:

The fireproof package is applicable to dry electricity, telecommunication, postal service, industrial and mining, enterprises, and construction. The plugging of voids formed when passing through the partitions or partitions, such as cables, oil pipes, air pipes, air pipes, and metal pipes, can prevent the spread of fire. It is especially suitable for the important parts where the cables are frequently replaced.

Construction method:

Electric shaft, with flameproof mesh, fire retardant plate or iron plate as the support pad, the fireproof package is laid on the mat, and the barrier is formed into the interlayer. The cable tunnel and the cable trench are in accordance with the relevant spacing requirements of domestic cable tunnels and cable shafts. Need to set up partitions, fire protection can be packaged into a firewall. When necessary, angle brackets can be made to facilitate closure.

Packing and shipping:

1. The fireproof package shall be attached with a plastic grade fireproof cloth bag, and then be packaged in a woven bag and stored in a cool and dry place.

2. Transport ordinary safe solid materials during transportation to prevent rain and sunlight.
