You often go through the tunnel when you get out of the car, and you can see that the inside of the tunnel is protected by plates. Do you know what the plates installed in the tunnel are? It is the tunnel fire protection board, which is a kind of energy-saving and environmental protection material. Another name of it is steel calcium plate. The following is the name of steel calcium plate to introduce the tunnel fire protection board.
The basic material of steel calcium plate is energy-saving and environment-friendly material fiber-reinforced calcium silicate plate (fiber-reinforced cement plate). Stainless steel installation components are clamped on one side or four sides of the basic material, and then combined by high temperature, high pressure and other modern processing technology. The galvanized aluminum steel plate or aluminum plate surface is coated with two layers of high weatherability, high temperature, high pressure, etc The color is more stable fluorocarbon paint or inorganic coating of new environmental protection materials.
The steel calcium board belongs to class A1 non combustible board, which is flame retardant and green. It can be used for fire wall, fire air duct, fire ceiling, steel beam and steel column fire packing, smoke wall and so on.
Steel calcium plate is widely used in building exterior walls, medical institutions, subway stations, tunnel construction and other underground space, because its product performance is relatively stable, structural connection is stable, and it can replace the aluminum veneer, aluminum plastic plate, stone, ceramic plate and other new energy-saving and environmental protection materials used in the market at this stage.
It is resistant to salt and alkali, not easy to corrosion. Therefore, even in the rain, frost, temperature change, sunshine, cold, acid-base, high temperature and other harsh environment, the stability of steel calcium plate can be guaranteed.
Steel calcium plate also has good sound insulation effect, the origin of tunnel steel calcium plate is because of its good sound insulation. The reason for this is that the steel calcium plate has the characteristics of cavity attraction, which makes the tunnel quiet and plays the role of noise reduction.
Steel calcium plate or green building materials, such as steel calcium plate of environmental protection building materials, more loved by people who love environmental protection.
