Fire protection systems
"Passive fire protection systems" on the basis of super thin basalt fiber
Fire occurs if there are three elements:
▪ heating source: spark when short-circuit, an overheated machine, unquenched cigarette butt etc;
▪ Combustible material such as furniture, clothes, books and so on.
In the absence of one of these elements, there is no risk of fire. Two of the above elements cannot be controlled: the heat source (usually random) and oxygen (always present in big quantities in the air). So, there's one element left: the combustible material. Fire safety can be achieved by using non-combustible or flame-retardant material.
Spread of fire
Once there is a fire, it spreads in three directions:
▪ Radial: flames contribute to the spread of fire to objects located in few meters from the source.
▪ Thermal conductivity: the heat is transferred from one object to another. The thermal conductivity of the material plays an important role in this process. Thus, the metal itself is not a flammable substance, but it transfers the heat faster than wood.
▪ Convection: Hot air and flammable gases rise and enhance combustion of other substances.
Behavior of different materials in case of fire
It's important to know how construction materials behave during a fire. Do they ignite easily? Do they contribute to the transfer of fire to other subjects? Do they emit large amount of smoke and gas? But there are other questions to be answered. For example, how does the material respond to high temperature? Will it be deformed, damaged (e.g. steel), cracked (e.g. gypsum)? As it's known, wood products react to fire more favorably.
Spread of fire
Fire spreads at the speed of the flames gliding over the surface of a material. The speed of the different materials varies. The extent of the spread of fire can be divided into four classes:
▪ Class 1 (M1) - The flame does not spread;
▪ Class 2 (M2) - Flame spread slightly;
▪ Class 3 (M3) - Medium speed of a flame spreading;
▪ Class 4 (M4) - High speed of a flame spreading.
Transfer of flame and flammability
The spread of fire is determined not only by the flame spread, but also by heating of noncombustible materials. In this case, the gases can be released and, in their turn, transfer fire to other items (flame transfer). Depending on the ability to pick up the flame, materials is also divided into four classes:
▪ Class 1 - The material is non-flammable;
▪ Class 2 - Hardly flammable material;
▪ Class 3 - Medium degree of flammability;
▪ Class 4 - High degree of flammability.
The "Magma Industry" company offers the products of super thin basalt fiber for fire protection. They include: super thin basalt fiber (STBF) for dry and wet air drawing, cartoons on the basis of STBF bentonite clay and the STBF systems on metal meshes. The products made of MagmaWool ™ basalt fibers belong to Class 1 (M1), i.e. they are absolutely non-combustible and meet the most stringent fire safety standards.
Fire protection systems on the basis of super thin basalt fiber can withstand 1000°C for 2 hours. Also, they do not emit any smoke or gas under the influence of fire.
Thanks to this, the system of fire protection made of super thin basalt fiber have unique characteristics and hardly have any analogues in the world!
