For indoor perforated sound-absorbing aluminum veneer

Hole aluminum single good corrosion resistance, high strength, good surface gloss, easy bending welding, processing into various shapes, with shockproof. Waterproof. Flame retardant, good noise reduction effect, is the current mainstream decorative noise reduction material, mainly used for the sound absorption decoration design of the inner wall and ceiling of sports buildings. Perforated aluminum veneer aperture and hole distance die effect is roughly as follows: a play a sound-absorbing role also known as sound-absorbing board, mostly used in densely populated buildings, this plate aperture is not large, high density; the other is a decorative role, its hole shape and aperture is relatively small.

　　1. Sound absorption performance

The technical requirements for all aspects of sports venues are very high, and its indoor acoustic design is also an important aspect that can not be ignored. It is necessary to fully consider the sound absorption effect of the whole space, from the wall to the ceiling, to design and use sound-absorbing decorative materials to meet the acoustic requirements. Now, perforated sound-absorbing aluminum plates, micro-perforated honeycomb aluminum plates and other metal materials are more commonly used in combination with glass wool. Due to the simple processing of aluminum plate, the perforation rate can be designed differently according to the indoor sound quality requirements. The sound absorption coefficient can be controlled within a certain range by controlling the perforation diameter, hole distance, plate thickness, etc., which not only achieves the design effect but also reasonably controls the cost. The test results show that when the perforation rate of the aluminum plate is less than 30%, the sound absorption coefficient increases with the increase of the perforation rate, and when it exceeds 30%, the sound absorption coefficient decreases with the increase of the perforation rate. Different caliber, perforated aluminum plate processing sound frequency is not the same, microporous processing is treble, the larger the aperture, the lower the absorption frequency.

　2. Decorative effect

Aluminum perforated aluminum plate can produce a variety of decorative visual effects by controlling its perforation rate, hole type and color, and can be used in important building interior spaces. Through the design and use of perforated aluminum plate function, as well as lighting, air conditioning and ventilation equipment, fire fighting facilities and other reasonable arrangements, the use of printing, carving, three-dimensional modeling and other techniques to create a rich variety of indoor space. Aluminum plate finish paint can be used pearlescent spraying, coating roll, fluorocarbon spraying, etc., the color can be customized according to the need.

Perforated aluminum veneer excellent material properties, shaping the visual sense of the whole, the advantages of reducing energy consumption, so that it has a wide range of application prospects in the indoor and outdoor sports building, the architect\'s mastery of materials and the ability to use is a compulsory course in the design career.
