Aircraft fire highlights aerogel should be standard
Fire, see fire again.
On the 5th of May, a pilgrimage plane from Moscow to Murmansk returned to Sheremetyevo airport in Moscow and caught fire during an emergency landing.
The TV news screen showed that the plane violently bumped when landing, and then the flames and black smoke suddenly appeared in the rear, and some passengers then escaped through the inflatable slide. When the fire was extinguished, the rear of the fuselage was completely burned and the top collapsed.
At the time of the incident, there were thunderstorms in parts of Moscow. Some analysts say that the cause of the fire may be that lightning hit the aircraft engine.
The Russian investigation committee said that there were 78 people on board, of which only 37 were still in life and 41 were killed.
According to the Russian Tass news agency, a source of law enforcement revealed to them that most of the victims of the crash were killed by burning products.
The source said: "The cause of death of the victims on board will be determined by forensic examination. For now, most people die of poisoning."
This judgment is not unexpected - there are statistics showing that in the fire, more than 70% of the victims were not burnt, but inhaled to death or suffocation.
According to experts, when the fire burns, a large amount of toxic gases such as carbon monoxide and hydrogen chloride, carbon dioxide and smoke are generated, which makes people unable to breathe normally and soon suffocates and dies.
Under normal circumstances, when the content of carbon monoxide in the air reaches 1%, people will lose consciousness after inhaling several times, and may die of poisoning after 1-2 minutes. Even if the content is only 0.5%, the human body is life-threatening 20-30 minutes after inhalation, and people who are inhaled by carbon monoxide at the scene of the fire are awake, often leaving different degrees of sequelae.
Toxic gases produced by the combustion of organic substances such as polyvinyl chloride are more lethal. For example, hydrogen chloride is highly irritating, causing damage to the upper respiratory tract and forming mechanical suffocation, which can cause death in a short period of time. If the raw materials, intermediates, etc. of foamed plastics and chemical fiber fabrics are burned, highly toxic gases such as phosgene, chlorine gas and hydrogen cyanide may be generated, and inhalation may cause poisoning and suffocation.
The large amount of carbon dioxide produced in the combustion of the fire, although not toxic, will reduce the oxygen content in the air, and will also pose a life threat to the lives of the field personnel.
The past has been embarrassed, the tragedy has taken place;
We can chase after the day, we can use aerogel materials to avoid the recurrence of the tragedy.
Tradematt independently develops and produces aerogel materials. The main component is silica. According to the inspection of authoritative organizations, it can reach the Class A non-combustible standard of GB8624-2012 "Building Materials and Products Combustion Performance Classification".
Therefore, if aerogel materials are used to protect aircraft, automobiles, high-speed trains, etc., even in the event of a fire, aerogel materials can prevent the fire from spreading and give the occupants a longer escape time.
Moreover, even if the aerogel material is swallowed by fire, there is no open flame, no droplets, and no toxic fumes. Therefore, when the traditional materials are replaced by such advanced materials, the lethality of the fire is greatly reduced.
At present, Tradematt has reached strategic cooperation agreements with a number of R&D institutions and well-known enterprises in the aviation field. In the near future, aerogel materials will become the “golden bell” of aircraft and the “protective god” of passengers.
