Introduction to polyester fiber sound-absorbing decorative panels
Polyester fiber sound-absorbing panels have the functions of sound absorption, muteness, noise reduction, and flame retardant. The material is uniform and solid. It is not only elastic, tough, wear-resistant, impact-resistant, and not easy to scratch. It is in contact with the cavity. The thin-plate resonant sound absorber is extremely effective and is a wide-band, high-efficiency sound-absorbing material. In addition, polyester fiber sound-absorbing decorative boards are light in weight and have excellent material properties. Unlike some brittle materials such as perforated gypsum boards and cement fiber pressurized boards, which produce fragments or fragments, there is a danger of falling, and the formaldehyde/formaldehyde emission level is far from the standard. The formaldehyde emission is less than or equal to the national standard. It is a new acoustic material that replaces the previous laminates plus sponge or glass fiber. It is easy to destroy, does not pollute the environment, and can be recycled.
The sound-absorbing principle of polyester fiber board is that there are a large number of tiny connected pores inside the material. Sound waves can penetrate deep into the material along these pores, causing friction with the material to convert sound energy into heat energy. It is a porous sound-absorbing material. The sound absorption characteristic is that the sound absorption coefficient gradually increases as the frequency increases, which means that low-frequency absorption is not as good as high-frequency absorption.
The necessary condition for sound absorption of porous materials is that the material has a large number of voids, the voids are connected to each other, and the pores penetrate deep into the material. One of the misunderstandings is that materials with rough surfaces have sound-absorbing properties. In fact, this is not the case. For example, stones with uneven surfaces such as roughened cement have basically no sound-absorbing properties. The second misunderstanding is that materials with a large number of holes inside the material, such as polystyrene, polyethylene, closed-cell polyurethane, etc., have good sound absorption properties. In fact, these materials have no connectivity within the holes, so sound waves cannot penetrate deep into the material. Vibration friction, so the sound absorption coefficient is very small. The sound absorption mechanism of the sound absorber structure composed of polyester fiber board and cavity body is thin plate resonance sound absorption. At the resonant frequency, a large amount of sound energy is absorbed due to the violent vibration of the thin plate. It has good sound absorption performance for medium, high and low frequencies.
Cleaning problems: Use a vacuum cleaner to clean dust and other adherents. Small areas can be wiped with detergent when applying liquid. Large areas can only be removed by replacing the board.
Performance characteristics
High sound absorption rate
Good sound insulation
Flame retardant grade
Tight structure and stable shape.
Very light weight, safe and convenient to construct
Harmless to human body, no pollution to the environment, odorless
Water-resistant, strong drainage after water immersion, sound-absorbing performance will not decrease, and shape will not change.
It can be used twice, is easy to destroy, and has no secondary pollution to the environment.
Melting point degrees Celsius
Introduction to polyester fiber sound-absorbing decorative panels
Polyester fiber sound-absorbing panels have the functions of sound absorption, muteness, noise reduction, and flame retardancy. The material is uniform and solid, and it is not only elastic, tough, wear-resistant and impact-resistant. Scratched, the thin plate resonance sound absorber formed by it and the cavity has an excellent effect. It is a high-efficiency sound-absorbing material with a wide frequency band. In addition, polyester fiber sound-absorbing decorative boards are light in weight and have excellent material properties.
