The first type: stick to the wall, all-purpose adhesive or structural adhesive can be used;

The second type: steel nails hit the wall;

The third type: fix the keel on the original wall, and then fix the sound-absorbing board on the keel.

Each of the three methods has its advantages and disadvantages. Glue construction speed is fast, the surface is smooth, but it will smell of formaldehyde, and there must be a good ventilation environment after construction; Steel nails are directly fixed on the wall, and there will be nail holes on the surface, which will be ugly if not handled properly; The sound-absorbing board can be fixed on the keel with straight nails, which is more beautiful, but it will affect the surface flatness.

To sum up, you can choose the appropriate construction method according to the actual situation on site.

Extended data:

Sound absorption mechanism of sound absorption plate

Wooden ceiling or wallboard, etc. The sound absorption mechanism of this structure is thin plate vibration sound absorption. At the vibration frequency of * * *, due to the violent vibration of the thin plate, a lot of acoustic energy is absorbed.

* * * Most thin plates have good sound absorption performance at low frequencies;

(1) has large surface and high flatness.

(2) The board has high strength and light weight.

(3) Good sound absorption effect, fire prevention and waterproof.

(4) The installation is simple, and each board can be disassembled and replaced separately.

(5) In terms of size, shape, surface treatment, color, etc., it can be customized according to customers' needs to meet their individual needs.

Ecological wood sound-absorbing board

Ecological wood is a revolutionary new environmental protection material and the most mature product of wood substitution technology in the world. It is made of a small amount of polymer materials and a large amount of wood powder by patented technology without any surface treatment.

By recycling wood, the comprehensive utilization rate of wood is greatly improved, and the production process is pollution-free. At the same time, it solves the problem of recycling waste resources in plastic and wood industries, which is in line with the major policy of energy conservation and emission reduction advocated by the state to establish a conservation-oriented society.
