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.
Hole design
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.
The method of installing acoustic perforated gypsum board usually consists of the following steps:
Preparation:
Clean the surface of the substrate to ensure that it is flat and free from impurities
Special parts treatment.
Prepare the required materials and tools, such as gypsum board, acoustic material, electric drill, screwdriver, etc.
Special parts treatment.
Bouncing line positioning:
According to the design requirements, determine the installation position and elevation of the sound-absorbing board.
Special parts treatment.
Keel installation:
Installation of the main keel and secondary keel, the main keel usually adopts C38 keel, the spacing is generally 900-1200mm.
Special parts treatment.
Gypsum board cutting:
According to the size of the wall, cut the gypsum board into suitable size.
Special parts treatment.
Gypsum board fixing:
Use a drill and screwdriver to fix the plasterboard to the wall or keel
Special parts treatment.
The gypsum board is fixed to the light steel skeleton using self-tapping screws.
Special parts treatment.
Ensure that the plasterboard is firmly installed without loosening
Special parts treatment.
Seam treatment:
The gaps between gypsum boards can be sealed with joint tape and caulking paste.
Special parts treatment.
Inspection and adjustment:
After the installation is completed, carry out detailed inspection and adjustment to ensure that the installation is firm and the surface is flat.
Special parts treatment.
Special parts treatment:
For special parts such as wall edges, light holes, access holes, etc., they need to be handled and installed according to specific conditions.
Special parts treatment.
The above steps are the basic process of installing sound-absorbing perforated gypsum board, the specific operation may need to be adjusted according to the actual situation.
