Description
Technical Field
The utility model relates to an anechoic board preparation technical field relates to an environmental protection noise reduction anechoic board particularly.
Background
The sound absorption acoustics are mostly loose and porous acoustic materials, such as slag wool, blankets and the like, the sound absorption mechanism is that sound waves go deep into pores of the materials, the pores are mostly open pores with mutually communicated interiors, and the sound absorption acoustics are subjected to air molecule friction and viscous resistance and make fine fibers vibrate mechanically, so that sound energy is converted into heat energy. The sound absorption coefficient of the porous sound absorption material generally increases gradually from low frequency to high frequency, so that the sound absorption effect on high frequency and medium frequency sound is better. The sound absorption measures are used for sound absorption construction, when sound waves meet a barrier made of the sound absorption materials in the transmission process, a part of noise energy is emitted back by the barrier, and a part of energy cup sound absorption materials are absorbed. The sound absorption performance of the sound-absorbing material is related to the type of sound-absorbing material and the sound absorption coefficient. The commonly used porous sound absorption materials include inorganic fiber materials, foam materials, organic fiber materials, building sound absorption materials and the like.
The ventilation silencer is a device for reducing airflow noise by using the principles of sound reflection, interference, absorption and the like, and in a clean air-conditioning ventilation system, the silencer not only needs to have the function of reducing noise, but also needs to meet various requirements of a clean room, such as no dust accumulation in the structure, no bacteria breeding, no dust generation or no particulate matter generation of a used sound absorption material and the like. However, no sound-absorbing material which does not produce dust or fall off particles after long-term use is available in the market at present, so that some silencers for clean rooms are not filled with the sound-absorbing material, the method only solves the problem that the sound-absorbing material produces dust or separates from particles after long-term use, but reduces the silencing effect, dust can be accumulated in an internal cavity after long-term use, bacteria can be easily bred in a proper temperature and humidity environment in an air conditioning and ventilation system, the traditional silencer cannot be replaced and cleaned due to the fact that an internal microporous plate, an external enclosure and the like are all riveted or welded together, and at the moment, the interior of the silencer becomes a potential pollution source of a controlled environment in a clean room.
