Polyester fiber sound-absorbing board
Polyester fiber sound-absorbing board is called polyester fiber decorative sound-absorbing board, which is a decorative material with sound-absorbing function made of polyester fiber by hot pressing.
100% polyester fiber is hot-pressed by high technology and made in the shape of cocoon and cotton, which realizes density diversity and ensures ventilation, and becomes an excellent product in sound-absorbing and heat-insulating materials. The highest sound-absorbing coefficient reaches above 0.9 in the noise range of 125 ~ 4,000 Hz. According to different needs, the reverberation time is shortened, the sound impurities are removed, the sound effect is improved, and the language clarity is improved. The product has the characteristics of decoration, thermal insulation, flame retardant, environmental protection, light weight, easy processing, stability, impact resistance and simple maintenance. Become the preferred decorative sound-absorbing material for interior decoration.
Sound-absorbing property The sound-absorbing property of polyester fiber sound-absorbing board is similar to that of other porous materials. The sound-absorbing coefficient increases with the increase of frequency, and the sound-absorbing coefficient of high frequency is very large. The sound-absorbing property of the material can be greatly improved by leaving a cavity on its back and the space sound-absorbing body made of it. The noise reduction coefficient is about 0.8 ~ 1.10, making it an efficient sound absorber with wide frequency band.
Wood wool sound-absorbing board
Wood wool sound-absorbing board’s surface texture shows elegant texture and unique taste, which can fully interpret the designer’s creativity and ideas. This product combines the advantages of wood and cement: it is as light as wood, as firm as cement, and has many functions such as sound absorption, impact resistance, fire prevention, moisture prevention and mildew prevention, and can be widely used in stadiums, theaters, cinemas, conference rooms, churches, factories, schools, libraries, swimming pools and so on.
Wood wool sound-absorbing board is made of poplar fiber, combined with unique inorganic hard cement adhesive, by continuous operation technology and under high temperature and high pressure. This product has physical characteristics that can only be obtained by synthesizing several different building materials.
Unique appearance, good sound absorption-unique surface filiform texture, giving people a primitive and rough feeling, satisfying the concept of modern people returning to nature. The surface can be painted and painted, and it can be painted for six times. The maximum sound absorption rate can reach 1.00.
Wood sound-absorbing board
Wood sound-absorbing board can be divided into two types: grooved wood sound-absorbing board and perforated wood sound-absorbing board. Grooved wood sound-absorbing board is a kind of slit resonance sound-absorbing material with slots in the front and holes in the back of MDF. The perforated wood sound-absorbing board is a kind of structural sound-absorbing material with round holes on the front and back of the MDF. Two kinds of sound-absorbing boards are often used for wall and ceiling decoration.
Cross-sectional structure of wood sound-absorbing board: the principle of sound-absorbing board: There are many small holes on the surface of sound-absorbing board. After the sound enters the small holes, it will be reflected randomly in the inner wall of the structure which is a bit like a sponge until most of the energy of sound waves is consumed and turned into heat energy, thus achieving the effect of sound insulation. There are many tiny gaps in the sound-absorbing board, which have a sound-absorbing effect on sound waves, especially for sound waves with frequencies higher than 600Hz.Introduction of commonly used sound-absorbing materials.
