Product Description

Aluminum Perforated Sound Absorbing Board For Machine Room

With the rapid development of urban high-rise buildings in my country, more and more attention has been paid to the conflict between rapid economic development and environmental protection, and effective measures have been taken to reduce environmental pollution, reduce acoustic pollution, protect the environment, and promote the harmonious development of man and nature. In noisy rooms such as air intake fan room, exhaust fan room, fire pump room, refrigeration machine room, air conditioning machine room, generator room, etc., using aluminum perforated sound absorbing board as the sound absorption, sound insulation material or decoration panel for the wall and ceiling of the machine room Effectively reduce noise.

The sound-absorbing wall of the machine room and the perforated aluminum plate of the ceiling are made of international standard aluminum hot-rolled high-quality aluminum alloy plates. The panels are processed and formed by our company's professional flat stretching and compression molding processes. They have high processing accuracy and stable appearance. , High surface smoothness and other characteristics. The sound-absorbing wall of the machine room and the perforated aluminum plate of the ceiling are composed of the decorative surface perforated aluminum plate, the main and auxiliary keels and related accessories. The decorative panel can be square block (600×600mm), strip block (300×1200mm, 600×1200mm) ) Etc., made of pure aluminum or aluminum alloy.

The sound absorption principle of aluminum perforated sound absorbing board: According to the principle of cavity resonance sound absorption structure, after the perforated aluminum plate is installed, the back layer is an air layer to form a sound absorption structure. A closed cavity is connected to the external space through an opening, each opening The hole corresponds to a small cavity behind. When the frequency f of the external incident wave is equal to the natural frequency of the system, the air column in the neck of the hole will vibrate violently due to resonance. During the vibration process, sound energy is consumed due to overcoming frictional resistance. Adding 50mm thick glass wool on the back of the perforated aluminum plate has a very good noise and noise reduction effect.
