Do you know the difference between aluminum fiber sound-absorbing panels and aluminum alloy sound ba

1、 Aluminum fiber sound-absorbing board

Aluminum fiber sound-absorbing board is a metal type sound-absorbing material that is formed by rolling the aluminum fiber felt and aluminum foil sandwiched between two aluminum mesh plates. Aluminum fiber sound-absorbing board is a sound-absorbing material that belongs to the built-in sound-absorbing filling material of the sound barrier. Aluminum fiber sound-absorbing board has the following characteristics:

Ultra thin and lightweight: The thickness of aluminum fiber sound-absorbing board is generally around 1.3-2.0mm, and the surface density is between 1.5-3.2kg/m2. Due to the extremely small volume of materials, transportation and storage are very convenient.

The noise reduction coefficient NRC of 1.3mm thick is 0.7, and the noise reduction coefficient NRC of 1.8mm thick is 0.9

Decorative: The board surface can be sprayed with the required colors, with rich and beautiful colors, integrating decorative and sound-absorbing effects.

Convenient processing and construction installation: The board has good processability and is easy to drill, bend, and cut. During the construction and installation process, there will be no fiber dust flying and polluting the environment, which will affect the health of workers. The construction is simple and convenient.

Large material width: Aluminum fiber board is formed by rolling based on its plasticity, with a large width. In addition to the board, it can also be processed into various shapes of sound-absorbing bodies.

Recyclable: Made of pure aluminum metal, it will not form waste and cause environmental harm during replacement, so it is also an environmentally friendly product.

2、 Aluminum alloy sound barrier

Aluminum alloy sound barrier: Pure aluminum has low strength and is not suitable as a structural material. So by adding alloying elements and using heat treatment methods to strengthen aluminum, a series of aluminum alloys are obtained. The aluminum alloy sound barrier is a part of the sound barrier screen that is processed using aluminum alloy as a structural material.

3、 The difference between aluminum fiber sound-absorbing board and aluminum alloy sound barrier

Aluminum fiber sound-absorbing board serves as a filling material in the sound barrier; Aluminum alloy sound barrier is a structural material such as the panel, back panel, and keel of the sound barrier.
