According to reliable sources, today (April 29) morning around 7:00, a large-scale fire occurs Shanghai Hongqiao Terminal One underground space transformation process. It is reported that the fire was caused by the fire of the decoration materials. Witnesses said that the smoke on the scene was very large. After the incident, a large number of fire engines arrived, which has caused 2 deaths and 3 injuries. The specific casualties are still unclear. After learning the news, Xiao Bian was not only shocked but also a bit sorry for those who died and injured. If you can choose some fireproof materials when choosing decoration materials , it will not cause this accident. So how do you choose fire protection materials? The following decoration home decoration network Xiaobian integration of various aspects of information for everyone to bring the most detailed answers, friends come to the upswing posture.
How to choose fireproof materials?
1 , fire board
Fireproof panels are the most commonly used materials on the market today. There are two kinds of commonly used ones : one is high-pressure decorative refractory board, which has the advantages of fireproof, moisture-proof, wear-resistant, oil-resistant, easy to clean, and more varieties of colors; one is glass-magnesium fireproof board, the outer layer is decorative material, inside The layer is a mineral glass magnesium arson material, which can resist high temperatures of 1500 degrees, but the decoration is not strong. Fire-rated ceilings are installed at building exits, stairwells and corridors to ensure safe evacuation during fires and to protect people from spreading fires.
2 , fire door
Fire doors are divided into wooden fire doors, steel fire doors and stainless steel fire doors. Generally, fire doors are used for firewall openings, stairwell entrances and exits, evacuation walkways, pipe well openings, etc., which play an important role in fire separation and reduction of fire damage.
3 , fireproof wooden window frame
A wooden sealing material is embedded around the fireproof wooden window frame. When it expands with heat, it can prevent the flame from entering through the gap. Even if the fire outside the house is fierce, it can also be fire-resistant for 30 minutes. This kind of window frame is made of pine wood, and a sealing material made of graphite is attached around it to block the fine gap and increase the fireproof effect. According to the experiment, at 10 cm from the window frame, the flame frame was used to align the window frame, and the flame with a temperature of up to 800 °C was sprayed . After 20 minutes, the flame failed to pass through the window frame, indicating that the fireproof effect was aluminum window. Several times the box.
4 , fire shutter
In the inconvenient setting of the firewall in the building, the fire shutter can be set. The fire shutter generally has good functions of fireproofing, heat insulation, smoke, pressure, anti-aging and abrasion resistance.
5 , fireproof and anti-mite wood
Fireproof and tamper-proof wood is first immersed in a solution containing cations such as calcium and aluminum, and then immersed in a solution containing anions such as phosphate and silicate. In this way, the two ions react chemically in the wood to form a ceramic-like substance and tightly fill the voids of the cell tissue, giving the wood fire and tamper resistance.
6 , fire storage box
Can withstand relatively high external temperatures. Can be placed independently or embedded in a wall. It protects valuables such as coins, books, vouchers, tapes, audio tapes, and photographic negatives from damage during a fire.
7 , fire glass
Fireproof glass has good light transmission performance and fire resistance, heat insulation and sound insulation performance. Common fireproof glass has three kinds of laminated composite fireproof glass, wired fireproof glass and hollow fireproof glass. Fireproof glass is an important place for financial insurance, jewellery, books, archives, valuables collection, financial settlement, and other public buildings such as commercial buildings, hotels, theaters, hospitals, airports, computer rooms, station terminals, and other fire-proof separation requirements. Ideal fireproofing materials for fire doors, windows and fire barriers for industrial and civil buildings.
8 , fire retardant coating
Fireproof coating is a special type of fireproof protective coating. It is a solvent-based coating composed of chlorinated rubber, paraffin wax and various fireproofing additives. It has good fire resistance and is applied to the surface of ordinary wires. It expands to produce 200 mm thick foam in case of fire . Carbonized into a protective layer, isolated from the fire source, suitable for fire protection of indoor and outdoor cables of buildings of higher grades such as power plants and substations.
9 , fire blocking materials
The fireproof sealing material is used to block various penetrations, such as various openings formed by cables, ducts, oil pipes, natural gas pipes, etc., which pass through the wall (slab) wall and the floor (a) board, and the sectional fire prevention of the cable bridge. Separated to prevent the fire from spreading through these openings and gaps, it has a fireproof function and is easy to install. It includes organic fire blocking materials, inorganic fire blocking materials and fire retardant bags.
10 , fire protection package
Fireproof package, mainly used for fireproof plugging of various types of cable through holes in electric power, communication, petrochemical, construction and shipbuilding industries, can effectively prevent the fire from spreading along the cable, and avoid the loss of life and property to the maximum extent. under good ventilation, acid, water, oil, light weight, easy to use features, fire charring rapid expansion is formed with a certain thickness and strength firestop barrier, and absorbs heat expansion during carbonization, release The non-combustible gas achieves the purpose of fire prevention, heat insulation and smoke separation, and is an ideal product for fireproof and flame retardant of power cable facilities.
11 , fireproof plastic materials
Fireproof plastic materials are mainly used in high-energy and high-temperature electrical appliances, such as printers and hot air cylinders. The fire rating is achieved primarily by modifying the resin or adding different materials. Addition materials usually include glass fiber, calcium carbonate, and the like. The resin is co-injected into a fireproof plastic material in different proportions.
The above is what Xiaobian brought to you. Â It is very important to choose fireproof materials for fire in the underground of Shanghai Hongqiao Airport Terminal . I believe everyone has a basic understanding of how to choose fireproof materials after reading this article .
