Ordinary train aluminum foam floor is composed of 1mm aluminum plate, 15-20mm Aluminum rail transit foam sheet plate , 1mm aluminum sandwich plate, Aluminum rail transit foam sheet plate density is about 0.5g/cm³, with excellent sound insulation, isolation function;No combustion, good fire performance;The bending strength reaches about 20Mpa, and the service life is more than 30 years.Light weight, about half the weight of the board.
2.Make the inner lining of the carriage
Subway cars‘ lined with 20mm thick Aluminum rail transit foam sheet plate , which reduces noise by more than 20 decibels.The side lining of large line trains, high-speed trains and urban rail trains is made of 20mm Aluminum rail transit foam sheet plate and 20mm polyurethane foam composite board, which have good heat insulation and sound insulation performance.
3. Make sound absorption lining of subway station
The side wall and top sound absorption board of subway station are made of perforated aluminum foam sound absorption board with a thickness of 10mm and a 20mm thick cavity at the back. The sound absorption and noise reduction effect is still good even in the humid environment of subway station, which is more than twice as good as that of other sound absorption materials.
4. Making the compartment wall
The Aluminum rail transit foam sheet plate is used to make the passenger car partition wall, which has good sound insulation and vibration isolation function.
5. Making high-speed train floors
Aluminum foam flooring for high-speed trains is composed of 1mm aluminum foam board, 25-30mm Aluminum rail transit foam sheet plate and 1mm aluminum sandwich board. The aluminum foam density is about 0.5g/cm³.Sound insulation above 20 db, vibration to reduce an order of magnitude, fire, corrosion resistance, bending strength to reach about 20Mpa, not collapse, service life of more than 30 years.
6. Make train door sandwich
Aluminum rail transit foam sheet plate as the door sandwich material, with excellent sound insulation, shock isolation, heat insulation, bearing the load, isotropic.
