Nonmetal sound absorption board

Technical Field

Background

The sound absorbing board is an ideal sound absorbing decorative material. The sound absorption, environment protection, flame retardance, heat insulation, heat preservation, moisture resistance, mildew resistance, easy dust removal, easy cutting, split, simple construction, good stability, good shock resistance, good independence, high cost performance and the like, has the advantages of enriching various colors for selection, and can meet the sound absorption and decoration requirements of different styles and layers. The noise elimination and sound insulation construction requirements of the existing outdoor construction sites are becoming more and more popular, and the effects of environment protection and noise reduction are achieved. The metal sound absorbing plate is widely applied due to the advantages of light weight, high strength, convenient and fast field installation, no pollution, high production efficiency and the like.

However, in some special construction environments, metal sound absorbing boards cannot be used due to their electrical conductivity. In the construction of a power supply system of a national power grid, a common metal sound absorption plate cannot be normally used under the requirements of high insulativity, electric conduction resistance, static resistance and the like. Therefore, the existing construction mode is to replace a nonmetallic sound-absorbing plate, for example, the patent number is CN 109024328A, and the essence is to use reinforced concrete as a box body, utilize a concrete microporous structure and match sound-absorbing materials to absorb sound and reduce noise. However, the existing nonmetallic sound absorption plates are mostly integrated, so that the mass is large, the site installation is inconvenient, the construction efficiency is low, and the application range is small. Whereas, the acoustic panel produced by using a nonmetallic material as a core member has a high individual cost, resulting in an increase in construction cost. There is therefore a need for a non-metallic sound absorbing panel to solve the above problems.
