Sound-absorbing perforated gypsum board is a kind of building material with gypsum board as the substrate, perforated and backed with sound-absorbing material, which has the following characteristics and applications:
Material properties:
Acoustic performance: sound-absorbing perforated gypsum board can absorb sound wave energy, effectively adjust the reverberation time of the room through the
combination of different aperture diameters, aperture spacing, perforation rate and cavities, and the absorption of low-frequency sound waves is particularly significant.
Decorative: The surface is flat, and the board can absorb sound wave energy.
Decorative: the surface is flat, and the seamless surface is formed through the joint treatment between boards, and the surface can be decorated directly. At the same time,
the pores have various forms and rich combinations, which can form unique texture effects and have strong decorative properties.
Superior performance: light weight and strength.
Superior performance: light weight, high strength, good toughness, waterproof and moisture-proof, anticorrosion and moth-proof, heat insulation, and good fire resistance, fire resistance level can reach A, with good fire retardant properties.
Fire resistant grade can reach class A, with good fire retardant performance.
Green environmental protection: 100% free of asbestos, benzene, formaldehyde and other harmful substances, is a pure natural material.
It is pure natural material.
Application scope:
Sound-absorbing perforated gypsum board has been widely used in ceiling, wall cladding (instead of wall plastering layer) and various decorative panels of various buildings such as houses, office buildings, shops, hotels and industrial plants.
It is also suitable for concert halls, theatres and cinemas.
It is also suitable for acoustic places such as concert halls, theatres, recording studios, studios, listening rooms, conference rooms, gymnasiums, exhibition halls, dance halls, KTV rooms, family video halls and other acoustic places.
Product Information:
Size: common size 595595/603603mm, thickness 5-12mm, can be customised according to the design requirements
.
Hole design: provide square holes, large and small holes, slot hole design, and has a higher perforation rate than similar products.
Mechanism of sound absorption: there are a large number of tiny connecting pores inside the material, sound waves along these pores deep inside the material, and the material friction will be converted into heat energy.
The acoustic energy is converted into heat energy by the friction effect with the material.
To sum up, sound-absorbing perforated gypsum board is a multifunctional building material integrating acoustic performance, decorative and environmental protection, which is suitable for acoustic treatment and decoration in many occasions.
