The difference between aluminum fiber sound absorbing plate and aluminum alloy sound barrier
Second, aluminum sound barrier
Aluminum sound barrier: pure aluminum strength is very low, not for structural materials. So by adding alloying elements and the use of heat treatment and other methods to strengthen the aluminum, which got a series of aluminum. The aluminum sound barrier is made of aluminum alloy as a structural material, processed from the sound barrier screen part of the screen.
Third, the difference between aluminum fiber sound absorption plate and aluminum sound barrier
Aluminum fiber sound absorption board in the sound barrier which, as a filler material; aluminum sound barrier, is the sound barrier in the panel, backplane, keel and other structural materials.
First, aluminum fiber sound absorption board
Aluminum fiber sound absorption board, is made of aluminum mesh on both sides of the aluminum fiber felt and aluminum foil sandwiched by the rolling of a metal-type sound-absorbing material. Aluminum fiber sound absorption board, is a sound-absorbing material, belonging to the sound barrier built-in sound absorption material. Aluminum fiber sound absorption board has the following characteristics:
● ultra-thin light: aluminum fiber sound absorber thickness is generally 0.8 ~ 2.0mm or so, the surface density of 1.4 ~ 3.2kg / m2. Due to the small volume of material, transportation and storage is very convenient.
● 1.35mm thick noise reduction coefficient NRC 0.7,1.8mm thick noise reduction coefficient NRC is 0.9
● decorative: the board can be sprayed with the required color, rich color and beautiful, set the decorative effect and sound effects in one.
● easy processing and construction: sheet machinability is good, easy drilling, bending and cutting. Construction and installation process will not produce fiber dust scattered pollution of the environment and affect the health of workers, construction is simple.
● Material plate size: aluminum fiber board is the use of its plastic through the roll forming, large plate. In addition to sheet metal, but also processed into a variety of shapes of sound absorbers.
● recyclable use: made of pure aluminum metal, the exchange will not form waste waste on the environment caused by pollution, so it is itself an environmentally friendly products.
