PET Acoustic Panel is a noise-reducing material made from polyester fibers by hot pressing. It creates a quiet working and living space. It is easy to work with and can be shaped in a variety of ways using woodworking machines. PET Acoustic Panel is suitable for use in mining operations, construction sites, motor silencing, large equipment operating environments, and other acoustically demanding locations. Let's take a look at the PET Acoustic Panel.
Here is the content list:
What are the material characteristics of the PET Acoustic Panel?
How does the PET Acoustic Panel work?
How do I select a PET Acoustic Panel?
PET Acoustic Panels has a maximum absorption coefficient of 0.9 or more in the noise range 125 to 4000 Hz, shortens the reverberation time according to the needs, removes impurities, improves acoustics, and improves the clarity of speech. The PET Acoustic Panel has a high absorption coefficient of 9. PET Acoustic Panel has the characteristics of heat insulation, flame retardant, light body, easy processing, stability, impact resistance, and easy maintenance. PET Acoustic Panel can meet the requirements of different sound absorption and muffling effects, and is widely used in the field of sound insulation materials and acoustic engineering in China, and has been affirmed and praised by many famous domestic acousticians, and is trusted and chosen by mechanical designers and acoustic designers from all walks of life.
PET Acoustic Panel is a porous material that absorbs sound and forms a physical reaction within the panel, its main properties are sound absorption, silence, noise reduction, flame retardant, heat insulation, heat preservation, etc. The material is uniform and solid, not only is it elastic, tough, wear-resistant, impact-resistant, not easy to scratch, and the resonance of the thin plate with the cavity is good, it is a broadband efficient sound absorption material. The PET Acoustic Panel is a porous material with a large number of tiny connected pores, along the edges of which sound waves reach the interior of the material and generate heat by friction with the material molecules.
In addition, PET Acoustic Panel is lighter in texture and has excellent material properties, unlike some ordinary brittle materials such as perforated plasterboard and cement fiber pressurized board which produce fragmented cement blocks and are at risk of falling. PET Acoustic Panel is a new acoustic material breakthrough instead of the previous laminate with sponge or glass fiber, it is also easy to destroy without polluting the environment and has excellent recyclability.
The acoustic properties of PET Acoustic Panel are such that the absorption coefficient increases as the frequency increases, which means that low-frequency absorption is not as good as high-frequency absorption. The necessary conditions for a porous material to absorb sound are that it has a large number of voids, which are interconnected and penetrate deep into the material. When it snows, the ground, buildings, and trees are often covered with a layer of snow. Unlike ice, snow is not a hard solid, but a sparse snowflake containing many small voids, somewhat like the structure inside a PET Acoustic Panel. These voids have an absorption effect on sound waves, especially at frequencies above 600Hz. This is why the earth is so quiet on snowy nights.
Firstly, when identifying a PET Acoustic Panel, it is best to observe the quality of the mineral wool from the side of the PET Acoustic Panel that is best exposed, whether it is even, whether the mineral wool color difference is consistent, etc. This is a basic way to identify the quality of a PET Acoustic Panel.
Secondly, PET Acoustic Panel performance is the simplest standard to reflect the good or bad PET Acoustic Panel, on the PET Acoustic Panel sample label, the manufacturer will generally come with the corresponding PET Acoustic Panel information, including its sound absorption performance index, fire performance index, sound insulation performance index, moisture resistance performance index To determine the final quality of the PET Acoustic Panel, the manufacturer will provide information on the label of the PET Acoustic Panel, including its acoustic performance index, fire performance index, acoustic performance index, and moisture resistance index.
Third, look at the brand, and brand goods to ensure that its product equipment, technology, technical personnel, pre-sales, sales, and after-sales service brand quality, so that the quality of PET Acoustic Panel will have quality, after-sales service guarantee. Fourth, the weight of the product, different products have different weights, and different densities and their quality is not the same. But not that the quality of heavy is necessarily good, but also combined with the actual go to see the. Fifth, look at the appearance, the appearance of the appropriate color looks comfortable, smell the natural wood smell followed by fire, flame retardant, there are waterproof advantages, look at its workmanship, the work master groove surface is relatively fine not rough, and vice versa is poor. Sixth, high-quality PET Acoustic panels can do some staggered shapes, and then customers can modify and reshape according to personal preferences, which is generally not designed by small PET Acoustic Panel manufacturers.
