Description

Technical Field

[0001] The utility model relates to the field of sound absorption and noise reduction, in particular to an ultra-microporous sound absorption board with combined holes. Background Art

[0002] The sound-absorbing board is finely processed according to the acoustic principle. It is composed of facing, core material and sound-absorbing felt. It includes metal sound-absorbing board, polyester fiber sound-absorbing board, etc. The panel mainly has round holes, micro-perforations, composite through holes and louver holes. Rock wool and other sound-absorbing bodies are mainly added to the cavity. According to the micro-perforation theory, the micro-perforations and ultra-microporous composite pinhole board’s own sound-absorbing ability are used to absorb and reduce noise.

[0003] The Chinese patent with the announcement number CN214246407U discloses a prefabricated part with microporous ceramsite and a sound-absorbing board thereof. The prefabricated part is formed by mixing and curing ceramsite with a gelling agent, and the ceramsite has micropores inside. The gelling agent is an inorganic material such as cement, lime, or an organic material such as epoxy resin, polyurethane, etc., which is mixed and fixed with the ceramsite to form a sound-absorbing board. The prefabricated part is cut, and the ceramsite is destroyed on the cut surface to expose the broken wall micropores, so it has a sound-absorbing effect. The utility model destroys the ceramsite glaze skin to expose the internal microporous structure to achieve the purpose of sound absorption. However, in the above patent, multiple sound-absorbing boards need to be assembled together for use with the help of screws or adhesives when in use. The use of screws for assembly will cause damage to the sound-absorbing board, affecting the normal use of the sound-absorbing board, so that there is a problem of troublesome assembly operation when assembling the sound-absorbing board. For this reason, we propose an ultra-microporous sound-absorbing board with combined holes. Utility Model Content
