1. What is the sound-absorbing board?
Acoustic board is an ideal sound-absorbing decorative material. It has the advantages of sound absorption, environmental protection, flame retardancy, heat insulation, heat preservation, moisture prevention, mildew prevention, easy dust removal, easy cutting, inlaying, simple construction, good stability, good impact resistance, good independence and high cost performance. There are many colors to choose from, which can meet the attractive decoration needs of different styles and levels.

Third, the sound absorption mechanism of sound absorption board
A ceiling or wallboard made of wood, 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.
Fourth, how to choose the sound-absorbing board
See if there is a test report on the performance of the sound absorption board.
Theoretically, any material has sound insulation performance, even a thin piece of printing paper can sound insulation, so many materials on the market are just very common, and manufacturers call them sound-absorbing boards, including gypsum board, magnesium board, calcium silicate board, wood board and so on. This makes it easy for consumers to be deceived. One of the most important principles in selecting the sound-absorbing board is whether the sound-absorbing board has an authoritative test report.
See if the installation of the sound-absorbing board is simple.
In order to achieve good sound insulation effect, the installation method of sound absorption board must be very simple, otherwise it is difficult to achieve ideal sound insulation effect. Professional acoustic engineers all know that if a wall can insulate X decibels in the laboratory, it can only insulate X-2 decibels in practical engineering, or even the sound insulation effect is lower.
Look at the thickness and weight of the sound-absorbing board
There are some common sound absorbing boards on the market. In order to improve the sound insulation effect, it is achieved by increasing the thickness and weight of wallboard. This method can improve the sound insulation effect to a certain extent, but it brings many disadvantages. Acoustic board is a kind of sound insulation material based on a brand-new sound insulation principle. Its remarkable sound insulation effect can not be achieved by increasing the weight and thickness. In fact, the thickness of the sound-absorbing board is only 18mm, or even thinner, but the sound insulation effect of the light steel keel wall composed of it can reach 53 decibels, and the sound insulation effect of the wall can even reach 80 decibels by adopting a suitable wall combination scheme. This kind of sound-absorbing board has the best sound-insulating effect among the sound-absorbing board products with the same thickness and weight in the market, which is many times better than any sound-absorbing board with the same thickness and weight.
See how long the sound insulation can last.
Some sound-absorbing boards in the market are made of rubber layer, damping material or sound-insulating felt installed between two boards. Using this method, the sound insulation effect can be improved to some extent in the short term, but with the passage of time, its sound insulation effect will gradually decrease. As we all know, rubber and other materials will age slowly in the air, which will lead to their gradual hardening and loss of elasticity, thus leading to the gradual decline of sound insulation effect over time. On the other hand, the construction cost of installing rubber layer or sound insulation felt layer between two boards is also very high.
Look at the strength of the sound-absorbing board, waterproof and fireproof.
While improving the sound insulation effect of the wall, we should also pay attention to other properties of the wall, such as whether the strength of the newly-built sound insulation wall or the old wall meets the requirements. If you want to hang heavy objects on the wall, such as flat screen TV, large oil painting or photo frame, large decorative lights, etc. You need the wallboard to be strong enough to bear a certain weight. If there are many people in the room or there are many people, it is necessary for the wallboard to have strong impact resistance and high strength to avoid the wall cracking caused by people hitting the wallboard. If the wallboard is close to wet parts such as faucets and toilets, it needs good waterproof performance. If the fire resistance of the wall is high (such as the wall of kitchen and garage, ceiling, etc.). ), be sure to buy a sound-absorbing board that is both sound-proof and fire-proof.
