Lightweight 4'x8' Wall Ceiling Panels Aluminum Micro Metal Non-combustible Acoustic Board
The micro perforated product adopts the microperforated sound absorption concept proposed
by the academician Ma Daxuan of China, who is a famous international acoustician .
The micro-wave structure on the surface of micropores changes the transfer path under the clever arrangement of the shin and the rib, absorbing a large amount of particle impact energy, and the micro holes in the trough cause the particles to be squeezed and rubbed because of the speed difference caused by the oblique microperforated acoustic impedance effect which will lead to the loss of kinetic energy when particles are penetrated.
The remaining energy particles after penetration also cause particle viscous effect and diffusion interference due to the 500,000 “geometric surfaces” per square meter on the backside resonate in the cavity , allowing the sound energy to decay in the process of resonance in cavity to achieve good sound absorption

FAQ :
Q: How do you clean aluminum perforated panels?
Cleaning aluminum perforated panels is a simple process. You can use a mild detergent solution and a soft-bristled brush or a soft cloth to remove dirt and stains. Avoid using abrasive cleaners or wire brushes as they can scratch the surface of the panel.
Q: Can aluminum perforated panels be recycled?
Yes, aluminum perforated panels are recyclable. Aluminum is a highly recyclable material, and it can be melted down and used to make new products.
