Introduction of aluminum honeycomb perforated sound absorption board
The structural structure of the perforated aluminum honeycomb sound-absorbing board is a perforated panel and perforated back panel, which is directly bonded to the aluminum honeycomb core by high-quality adhesive to form an aluminum honeycomb sandwich structure, and a layer of sound-absorbing cloth is pasted between the honeycomb core and the panel and back panel. As the honeycomb core in the honeycomb aluminum plate is divided into many closed chambers, the airflow is blocked, the sound wave is blocked, the sound absorption coefficient (up to 0.9) is increased, and the strength of the plate itself is increased, the size of a single plate can be larger, and the design freedom is further increased. According to the indoor acoustic design, different perforation rate designs can be carried out to control the sound absorption coefficient of the combined structure within a certain range, which can not only achieve the design effect but also reasonably control the cost. By controlling the hole diameter and the whole distance, and changing the hole rate according to the customer's requirements, the maximum hole rate is less than 30%. Generally, the hole diameter is ∮ 2.0, ∮ 2.5, ∮ 3.0, and other specifications. The requirements for the backplate hole are the same as those for the panel, and the sound-absorbing cloth is made of high-quality non-woven fabric and other sound-absorbing materials.
Aluminum honeycomb perforated sound absorption board
The installation process of aluminum honeycomb perforated sound absorption board:
1.The installation of ear type sound absorption board
This method is the separation type of lifting lug and honeycomb plate. After the lifting lug is processed separately, it is connected with the position of the glue joint of the honeycomb plate. The appropriate width of the glue joint is more than or equal to 12mm. This installation method is more simple and convenient to process.
2. The installation of flanging sound absorption board
This installation method is mainly used to process the aluminum honeycomb panel, that is to say, there is flanging for installation. The installation only needs to comfort the connection with the keel and the glue joint. The suitable glue joint width is no less than 10 mm. This method is convenient and simple to install, but the processing process is a little complicated, and it is not suitable for modeling curtain wall panels.
3. The installation of buckle type sound absorption board
This node is an aluminum buckle type, the buckle is a specific profile, and it is easy to install. However, this method requires high processing accuracy of the plate, and it is not recommended to use the plate with its length greater than 3000mm. According to the width of the buckle strap, the joints in the plate are 20 mm and 40 mm.
Features of aluminum honeycomb perforated sound absorption board:
1. High-quality fireproof performance: the aluminum plate is a noncombustible material in traditional materials.
2. Corrosion resistance: the surface of the aluminum honeycomb plate is treated with epoxy fluorocarbon, which has strong corrosion resistance. There is no pinhole, crack or blister in the salt spray for 48 hours.
3. Environmental protection: honeycomb panel is a pure aluminum vertical product, which does not volatilize any harmful gas to the human body, has no radioactivity and can be completely recycled. It is a 100% environmental protection product.
4. Aluminum honeycomb plate is easy to remove and assemble, and will not damage the plate. Because of its lightweight and convenient transportation, it can be transported to different places for repeated use. This is another partition board that cannot compare with it.
