I-coefficient ebanzi yokunciphisa umsindo yezinto ezintsha ze-aluminium foam ifinyelela ku-0.75, futhi i-coefficient yokumunca umsindo ebangeni elimaphakathi nefrequency engu-250~1000Hz ifinyelela ngaphezu kuka-0.9, idlula kude izinto ezivame ukusetshenziswa ezimunca umsindo njengoboya bedwala, ibhodi legypsum. , ipuleti lensimbi elinezimbobo, njll. Ukufakwa kwayo komsindo okuphelele nomsindo ikhono lokunciphisa i-polyurethane foam. Iphinda izikhathi ezingu-7-10 kunepulasitiki, ifayibha yengilazi ne-aluminium yekhekhe lezinyosi, futhi ukufakwa kwayo komsindo kusondele ku-30dB uma isetshenziswa ezitimeleni ezinesivinini esikhulu namaphaneli ebhokisi lezimoto. Izinto ezintsha ze-aluminium foam zisetshenziswa emikhakheni eminingi ngokumunca okuphakeme komsindo nokunciphisa umsindo kanye nezakhiwo ezihlobene, ikakhulukazi emigodleni yomsindo womgwaqo onguthelawayeka, ukuncishiswa komsindo womhubhe onguthelawayeka, ukuncishiswa komsindo womhubhe ohamba ngaphansi kolwandle, izimbobo zomhubhe; ukumuncwa komsindo wodonga lwamachibi okubhukuda; izinto ezintsha ze-aluminium ezinegwebu zokwenza ujenga lwesakhiwo olumunca umsindo, njengezitudiyo zokuqopha, amagumbi okukopisha, amahholo ekhonsathi, amahholo enkomfa, izinkundla, njll.
Izici eziyinhloko ezithinta ukumuncwa komsindo nomthelela wokunciphisa umsindo wezinto ezintsha ze-aluminium foam zimi kanje:
1. I-aluminium entsha ye-foam impahla iyimpahla enezimbotshana, futhi ukusebenza kwayo kokumuncwa komsindo kusobala kakhulu kumsindo wefrikhwensi ephezulu, okusho ukuthi, i-coefficient yokumuncwa komsindo inkulu endaweni yefrikhwensi ephezulu. Kodwa-ke, umphumela wokumunca womsindo womsindo wemvamisa ephansi awulungile kakhulu, ngakho-ke i-coefficient yokumuncwa komsindo endaweni yemvamisa ephansi incane;
2. Ugqinsi lwebhodi elimunca umsindo elenziwe ngento entsha ye-aluminium eyigwebu lihlukile, futhi imvamisa yokumunca umsindo ihlukile. Ngokukhula kokuqina, ukuvama okuhle kakhulu kokumunca umsindo kuzothuthukela ekumunceni kwefrikhwensi ephansi. Kodwa-ke, lapho imvamisa yomsindo inkulu kuno-500Hz, i-coefficient yokumuncwa komsindo yento entsha ye-aluminium eyigwebu ayihlanganise lutho nogqinsi;
3. Lapho ukuminyana kwezinto ezintsha zegwebu le-aluminium kukhula, imvamisa yokumunca kahle kakhulu yomsindo ngalesi sikhathi nayo izothuthuka ibe nomsindo wemvamisa ephansi, futhi usayizi wembotshana nenombolo yezinto ezintsha ze-aluminium foam nakho kunomehluko osobala ekumunceni komsindo. ukusebenza kwephaneli emunca umsindo.
Ukukubeka kalula, ukukhetha okuhlukile kwezinto ezintsha ze-aluminium foam, njengokushuba, ukuminyana, i-porosity, njll., kuzoholela emiphumeleni ehlukene yokumunca umsindo. Kungakhathaliseki ukuthi izinto ezintsha ze-aluminium foam zikhethwa kanjani, kuphumelela kakhulu ukulingana nesimo sabo.
