Aluminum honeycomb perforated sound-absorbing ceiling panel

The structural structure of the aluminum honeycomb perforated sound-absorbing ceiling panel is a perforated aluminum alloy panel and perforated back panel, which are directly bonded with high-quality adhesive and aluminum honeycomb core to form an aluminum honeycomb sandwich structure. A layer of sound-absorbing cloth is pasted between the honeycomb core and the panel and back panel. Because the honeycomb core inside the honeycomb aluminum panel is divided into many closed chambers, which hinders air activity, hinders sound waves, increases the sound absorption coefficient (which can reach above 0.9), and together improves the strength of the panel itself, making the scale of a single panel larger, further increasing the planning freedom. Being able to plan different perforation rates based on indoor acoustic planning, and manipulate the sound absorption coefficient of the combined structure within a certain range, not only achieves planning purposes but also enables reasonable cost control. After controlling the perforation aperture and spacing, the perforation rate and maximum perforation rate can be changed according to customer requirements
