acoustic panel

The aluminum strip gap sound-absorbing board is the only type of sound-absorbing material on the market that is assembled using aluminum profiles and has a surface with slot holes. Its appearance features long, narrow grooves. When installed in large areas, the overall effect is very ideal. The surface can be powder-coated in pure colors, transferred with various wood-grain or stone-pattern designs, and even electroplated with metallic colors. Almost all conceivable surface effects can be achieved.

The aluminum ultra-microporous sound-absorbing panel is 1.0mm thick with a pore size of 0.4*0.04mm. It prevents water droplets from penetrating and has excellent anti-penetration properties. With a perforation rate of less than 1%, it features a resonant sound-absorbing structure composed of a thin plate and a cavity behind it. The micro-wave structure on the microporous surface, cleverly designed with shanks and ribs, alters the transmission path, absorbing a large amount of energy from particle impact. Within the micropores within the troughs, the acoustic impedance effect of air particles passing through the oblique micropores creates a velocity difference, causing particle compression and friction. This leads to kinetic energy loss due to penetration, allowing the sound energy to resonate within the cavity and attenuate, resulting in excellent sound absorption.

The polyester sound-absorbing board is made by high-tech hot pressing of fiber strands with a diameter of only 13 threads. It naturally forms a porous structure, which can replace harmful traditional sound-absorbing boards such as sponge, glass wool, and rock wool. It is a new type of environmentally friendly sound-absorbing material that can come into direct contact with the human body without harming it, and does not release pollutants or fine fibers. With permanent flame-retardant technology, it is more advanced compared to the conventional flame-retardant process using soaking agents.
