Aluminum honeycomb sound absorption plate
The invention discloses an aluminum honeycomb sound absorption plate which comprises a box, an aluminum alloy plate and an aluminum honeycomb core. Sound absorption sponges are arranged in the box, a gypsum plate is attached to the back surface of the aluminum alloy plate and is arranged in a wavy manner, grooves are formed in the gypsum plate, the aluminum alloy plate and the box are hermetically arranged, the aluminum honeycomb core is fixedly connected with the box and is filled with asbestos fibers, a thin-layer chromatographic silica gel plate, aluminum silicate wool and a wood-wool sound absorption plate are sequentially attached onto the aluminum honeycomb core, glass fiber gridding cloth is inlaid in the thin-layer chromatographic silica gel plate, and the wood-wool sound absorption plate is adhered with the gypsum plate. The aluminum honeycomb sound absorption plate has the advantage of excellent sound-insulation performance.
