Perforated aluminum panel with good anticorrosion performance, have a certain strength, surface roughness is low, easy to machining into all kinds of shape, has a good shockproof, waterproof, fire prevention performance, and good sound effect, is a good decorate the deadening, widely used in sports building indoor metope and ceiling sound absorbing decoration design. The aperture and hole spacing of perforated aluminum panel will be affected by the processing process, there are generally two kinds: one is mainly played a sound-absorbing role is also called sound-absorbing board, used in densely populated buildings, this panel aperture is not large but the density is large; There is also a decorative role, its hole shape is different aperture relatively large density.
1, sound absorption performance
For stadiums with high technical requirements in all aspects, the internal acoustic design is also an important aspect that cannot be ignored. The sound-absorbing effect of the whole space should be fully considered. Sound-absorbing decorative materials should be designed from the wall to the ceiling to meet the acoustic requirements. At present, the more commonly used metal materials such as perforated sound-absorbing aluminum panel and microperforated honeycomb aluminum ppanel are used in combination with glass wool. Because aluminum panel processing is simple, according to the requirements of indoor acoustics, different perforation rate design, through the control of perforation aperture, hole distance, panel thickness, etc., in a certain range to control the combined structure of sound absorption coefficient, not only to achieve the design effect, but also reasonable control of the cost. According to the data, when the perforation rate of aluminum panel is less than 30%, the sound absorption coefficient increases with the increase of perforation rate, when the perforation rate is more than 30%, the effect of perforation rate on the increase of sound absorption coefficient decreases. Perforated aluminum panels process sound at different frequencies depending on the aperture. Micropores process higher-tone sound. The larger the aperture, the lower the sound absorption frequency.
- Decorative effect
By controlling the perforation rate, aperture, shape of the aperture and color elements of the aluminum panels, perforated aluminum panels can produce a variety of decorative visual effects that can be used in the interior Spaces of important buildings. Perforated aluminum panels can be designed according to the design effect and use function, combined with lighting, air conditioning ventilation equipment, fire facilities and other reasonable layout, using printing, carving, three-dimensional modeling and other techniques to create a rich variety of interior space. Aluminum panel front finish paint can be pearlescent spraying, rolling coating, fluorocarbon spraying, color can be customized according to requirements.
Perforated aluminum panel has the advantages of good material characteristics, shaping the overall sense of vision and reducing energy consumption, so that it can have a great application prospect in the indoor and outdoor sports buildings. Architects’ control and application ability of materials is a required course in their design career.
