Foam aluminum sound-absorbing board is mainly a new type of sound-absorbing material. It has very good physical properties and weather resistance, so its application range is very wide. Foam aluminum sound-absorbing panels can be roughly divided into two categories through materials. One is fiber-based sound-absorbing materials such as glass, cotton, slag wool and rock wool, etc., and the other is foam-based new materials, such as foam and foam. Glass and metal foam, etc.
And according to their different cell types, they can be divided into B-cell and open-cell foams. The internal cells of the closed-cell type are mutually closed, and this product also has good heat preservation and heat insulation performance, which is a kind of heat insulation. The blastholes in the open-cell type are interconnected, it has good air permeability, and it has a good lifting effect. Compared with the closed-cell foam material, although the thermal insulation performance is relatively poor, it is Belongs to a sound-absorbing product.
Foam aluminum sound-absorbing panels have high strength, but are not flame-resistant, water-resistant and high-temperature resistant, can withstand relatively large airflow, have good weather resistance, are easy to install, and have a long service life. The future maintenance of the foamed aluminum sound-absorbing panel is also very convenient, and it can be recycled, does not form solid waste, and does not cause any pollution to the environment. Because it has such good performance, it is not only suitable for indoor engineering, It is also very suitable for outdoor projects. For example, it can reduce investment in road traffic and make noise barriers.
Foam aluminum sound-absorbing board is a kind of metal sound-absorbing Dongzi. Compared with the new type of fiber that is widely used now, it has the characteristics of high strength, high rigidity and good weather resistance. Foam aluminum sound-absorbing panel is a kind of porous material. In addition to other materials, it also has a lot to do with the thickness of the material, the size of the cavity, and so on. Foam aluminum sound-absorbing board, its surface can be sprayed with various colors, so it can be used as a sacrificial material for interior decoration and can be used in business halls, theaters, lecture halls, gymnasiums, swimming pools, recording studios, etc. And the main outdoor use of the new version of the foam filter is to make some road traffic noise barriers, and will absorb some dust on the sacrificed surface.
