Product Name: Junhuian FHB-1 fireproof package, Junhui security fireproof package, fireproof package Fireproof package. Fireproof pillow

product description:

FHB-1 flame retardant bag is a new type of fireproof supporting refractories developed by our company according to GA161-1997 national standard. This product can be made into various shapes of firewalls, fireproof layers, and can be blocked according to different requirements of users. Holes that need to be fireproofed. In the event of a fire, the material of the fireproof package expands by heat and forms a honeycomb monolith. This effectively controls the fire within the local area and uses a fireproof package as a partition, replacing the refractory bricks and slag used in the past. Compared with cotton, ceramic wool and other materials, the fire retardant package has significant heat insulation effect. The product is suitable for electric power, telecommunications, postal services, chemical industry, industrial and mining, enterprises, and construction, cables, oil pipes, air pipes, gas pipes, and metal. The blocking of the holes formed when the pipeline penetrates through the partition wall or the partition can prevent the flame from spreading, and is particularly suitable for the important parts where the cable is frequently replaced.

One of the following conditions indicates that the test specimen has reached the fire limit.

Loss of integrity:

a. Light the cotton pad:

b. Pore formation with continuous 10s flame penetration:

c. Volumetric shrinkage of the material being inspected results in cracks above 1mm in width and visible flares to the naked eye.

Loss of heat insulation:

a. The temperature of the material to be inspected reaches 180°C at any point on the back of the fire surface;

b. The surface temperature rise of any penetrator back fire end material from the plugging material at 25mm to 180°C. When the fire resistance test is carried out to 180min: The fireproof package has no flame penetration on the back fire surface, no cracks are generated, and no completeness is lost; the highest single point temperature rise of the fireproof package back surface is 37.3°C, and the maximum distance from the fireproof package to the fireproof package is 25mm. Temperature rise 125.3°C without losing heat insulation.

Fire resistance >180min qualified

Third, the construction process:

1. Cable wells, use flame-proof nets, fire-retardant plates or iron plates as support pads, and block the fire-proof package on the mat.

2, cable tunnel and cable trench According to the provisions of the domestic cable tunnel and cable well spacing requirements, in the need to set the partition, the fire resistance can be packaged into a firewall, if necessary, can be made of angle steel bracket to facilitate the closure, Conservation.

Fourth, note:

1. The stack of fireproof bags should have a neat appearance and the thickness should not be less than 24cm.

2. The gap between the fire protection package and the cable shall not be greater than 0.1cm.

3, fire resistance package should be stored in a cool dry place, storage environment temperature is less than 80 °C.

The blockage of the holes formed in the compartments can prevent the spread of the flames and is particularly suitable for the important parts where the cables are frequently replaced.
