Abstract
The utility model discloses a sound-absorbing panel for metal perforation. Differing from a perforated metal panel, the sound-absorbing panel for metal perforation sequentially comprises a layer of perforated metal panel, a layer of non-woven fabric, a layer of centrifugal glass wool and another layer of non-woven fabric. The layers of materials are combined into an integrated structure through environmental protection adhesive. The sound-absorbing panel for metal perforation has the advantages of simple structure, easy processing, low cost, light weight, good decorative effect, beauty, environmental protection, increase in effective sound-absorbing area, high sound absorption coefficient, good sound insulation effect and high popularization and use value, thereby being a first-choice decorative slab for the interior and exterior decoration, the sound absorption in computer rooms, and the sound absorption and the noise reduction.
Description
Technical field
The utility model relates to a kind of metal piercing acoustic board, is loud material, and the sound absorption decoration is one.
