I-Aluminium Foam High-Efficiency High-Efficiency Acoustic Panels Itonela yokuFaka isandi kunye nokuNcitshiswa kwengxolo
Ingcaciso yeMveliso:
Iipaneli ze-aluminium ze-foam ezivaliweyo zenziwa kwiipaneli eziphezulu zokufunxa isandi emva kokunyangwa kwe-perforation (Φ2mm imingxuma, isantya se-perforation ye-1-3%), enomsebenzi ogqwesileyo wokuva isandi, kunye nesantya sokunciphisa isandi sinokufikelela kwi-60% ukuya kuma-90%. Ekubeni umphezulu wale nto ungenayo indiza, inomsebenzi obalaseleyo wokufunxa isandi, kwaye kwangaxeshanye, inomsebenzi wokufunxa isandi we-Helmholtz resonance acoustic absorber ene-perforated, eqinisekisa izinga eliphezulu lokufunxa isandi. Ukongeza, kwindawo enomswakama, izinto eziqhelekileyo ze-acoustic zithatha amanzi kwaye zanda, i-coefficient yokufunxa isandi iyancitshiswa kakhulu, ngelixa i-aluminium i-foam ayifuni amanzi, isantya sokufunxa isandi asinciphi.
I-Aluminiyam ipleyiti ye-foam emva kweseti yobunzima obuhlukeneyo bomgangatho womoya, i-frequency ephambili yokufunxa isandi yahlukile, kunye nobukhulu bomgangatho womoya ukusuka kwi-0mm ukuya kwi-90mm, i-frequency ephambili yokufunxa isandi ukusuka kwi-2000Hz ukuya kwi-300Hz okanye kunjalo. Xa ubukhulu bomgangatho womoya yi-10, 30, 60, 90mm, i-frequency engundoqo yezinga eliphezulu lokufunxa isandi yi-1000Hz, 500Hz, 400Hz, 300Hz okanye njalo. Ngokutsho kuyilo lonikezelo lwengxolo yoyilo logwebu lomgangatho wephaneli yeacoustic emva kobunzima bomoya. Uhola wendlela, iitonela ezingaphantsi komlambo, iitonela ezingaphantsi kolwandle kunye nezinye iimoto eziveliswe ingxolo engundoqo emalunga ne-400Hz, ingxolo ephantsi, ngoko ke izithintelo zesandi sohola wendlela, ngaphantsi komlambo kunye neetonela ezingaphantsi kolwandle ezifunxa isandi eludongeni lwe-aluminiyamu iiphaneli ze-acoustic emva kokuseta. Umaleko womoya ongqindilili we-60mm, umphumo wokunciphisa ingxolo ulungile. Ingxolo yomzila kaloliwe iphakathi kwaye iphezulu ingxolo yomoya ngaphezulu kwe-1000Hz, umaleko womoya oshinyeneyo ongama-20mm ibekwe emva kwepleyiti efunxa isandi se-aluminiyam kunye nesiphumo esihle sokunciphisa ingxolo.
