The fireproof package is a new type of cable fireproof material. The fireproof package is shaped like a small head. The external layer of fireproof pillow is commonly called “fireproof pillowâ€. The outer layer is woven tightly, and the durable glass fiber is made into a bag shape. The inside is filled with special fireproof, heat insulation material and intumescent material. The fireproof bag is non-flammable and expands and solidifies at high temperature to form a non-combustible seal wall with heat-insulating and smoke-proof. The fire resistance limit can be tested for more than 4 hours. The fireproof package has good fireproof and moisture resistance, is not afraid of damp failure, and does not contain asbestos and other toxic components. The product is packed in a variety of specifications, and the construction is very convenient. It is convenient for the replacement and maintenance of cables. Due to the small density of the fireproof package, it is particularly suitable for large holes or cable racks that require light material sealing.
The product is applicable to the plugging of voids formed when electric power, chemical industry, telecommunication, postal service, industrial and mining, enterprises, and buildings are used to penetrate through the partitions or partitions such as cables, oil pipes, air pipes, air pipes, and metal pipes. Prevents flame spread, especially for critical parts where cables are frequently replaced. It can effectively prevent the spread of fire along the cable and minimize the loss of life and property.
Product Appearance: Inclusion body intact, no breakage performance index Loose density: ≤1.2*103kg/m3
Water resistance: ≥3d The interior material has no obvious change. The inclusion body is intact without damage.
Oil resistance: ≥3d The interior material does not change significantly.
Compression strength: R≥0.05Mpa
Anti-dropping property: free fall on concrete level at 5m height, no damage to inclusion body.
Fire-resistance: fire-resistant material of Class 1 fire-proof material ≥180min
Construction method Cable well, use fireproof net, fire retardant plate or iron plate as support pad, lay the product on the mat, and build it into compartments. The distance between cable tunnel and cable trench according to domestic cable tunnels and cable wells It is stipulated that if you need to set up a partition, you can build a product into a firewall. When necessary, angle brackets can be made to facilitate closure.
1. Before the construction, clean the working surface so that there will be no oil, dust and other sundries. The cables will be combed in order.
2, neat code placed in the hole around the hole in the cable, the hole plugging tight. Sealing requirements are sealed, leaving no gaps.
3, through the floor or equipment holes, should first steel or steel mesh (must be brushed steel structure fire retardant coating) fixed at the bottom of the hole, fire prevention package code thickness of not less than 24 cm. Fireproof panels or other fireproof decorations may be added according to the requirements of the site (bare boards or other flammable materials shall not be used as brackets or cover plates).
4. The closure of the power distribution cabinets and control cabinets in the engine room shall be completely sealed in the floor space under the equipment, and the plugging area shall be greater than 24 cm around the base of the equipment. The cable shall be bent or sub-lined under the floor, and the plugging volume shall not be less than 24cm x 24cm x 24cm.
When the fire prevention package meets the fire, the filling in the package rapidly expands and foams several times or more than ten times to form a honeycomb block, which has a good fire insulation effect and blocks various openings and holes. Crevices can be extremely effective in controlling fires locally.
The product has the characteristics of good ventilation and ventilation, acid and alkali resistance, water resistance, oil resistance, light weight, easy to use and other characteristics at room temperature. It rapidly expands and carbonizes in case of fire to form a fire barrier with a certain thickness and strength, and is absorbed during the expansion carbonization process. Heat, release of non-combustible gas, fire resistance, heat insulation, and smoke separation are the ideal products for fire protection and flame retardant in power cable facilities.
