Inorganic Fiber Sound-absorbing Coating Material

Inorganic fiber sound - absorbing coating materials are a type of functional coatings made with inorganic fibers as the core aggregate, combined with cementitious materials, additives, etc. They achieve the absorption and dissipation of sound energy through the porous structure formed by the interweaving of fibers. These materials have advantages such as fire - resistance, high - temperature resistance, and strong durability, and are widely used in noise control scenarios in construction, industry, transportation, etc. Their core value lies in addressing the pain points of traditional sound - absorbing materials (such as rock wool boards and glass wool mats), such as complex installation, easy slag - dropping, and poor impact resistance. They are especially suitable for the sound - absorption and noise - reduction requirements of irregular surfaces, high - altitude or humid environments.

  • Materials: Mainly include inorganic fibers such as glass wool fibers and aluminum silicate fibers, as well as adhesives such as acrylic resin and latex. For example, cotton-based sandstone decorative sound-absorbing spray uses sound-absorbing cotton as the base and sandstone as the surface layer, which has good sound-absorbing performance. 

  • Applications: Suitable for ceilings and walls of large building spaces such as gymnasiums, exhibition halls, and airport waiting halls, and can also be used in industrial plants, underground garages and other places with noise reduction needs.

It is also often used in places with high requirements for sound absorption performance, such as concert halls, theaters, conference rooms, etc. It can be installed on walls and ceilings to improve the indoor acoustic environment and reduce echoes and reverberation.

acoustic noise reducers
acoustic noise reducers
A reactive muffler is an acoustic noise reduction device without sound-absorbing materials. It creates changes in acoustic impedance through sudden changes in pipe cross-sections (expansion chambers) or side-connected resonance chambers, causing sound waves to reflect and cancel each other out via interference, so as to reduce noise at specific frequencies.

Metal Acoustic Barrier
Metal Acoustic Barrier
metal acoustic barrier is a noise reduction measure with metal plates as the main body and sound-absorbing and sound-insulating materials installed inside. By physically blocking and converting sound energy, a sound shadow zone is established between the noise source and the sound reception point, achieving a noise reduction effect that attenuates the direct sound by 10~20 decibels.
