Characteristics of sound absorbing smallpox products
Introduction of aluminum alloy perforated sound absorbing board
Aluminum alloy perforated sound absorption board adopts computer numerical control punching equipment, chooses 1100H24, 3003H24 hot-rolled high-quality aluminum alloy sheet as the base material, and beautifies the aluminum panel with different specifications or patterns of punching technology, which can ease the depression caused by the closed type, if hidden, broaden the visual field of space perception. The aluminum facade finish can be painted, rolled, coated, and so on. The color can be customized according to the requirements.
Aluminum alloy perforated sound absorption board according to the piercing arrangement of thousands of variations, new composition, with excellent silencing, sound insulation effect. Our products are glued to non-woven fabrics or glass wool on the basis of punching. Especially, the effect of 3 punching products is outstanding.
Aluminum alloy perforated sound absorbing board has a variety of pattern combinations, and can be customized according to customer requirements. Perforated aluminum ceiling, its aperture size, aperture spacing and porosity are measured by the relevant acoustic measurement mechanism, generally speaking, the perforation rate in the 15% - 25% range has excellent sound absorption effect, sound insulation coefficient as high as 0.45-0.92as, large aperture is conducive to the absorption of bass, small aperture is conducive to the absorption of high-pitch.
