Customized aluminium foam composite panel Aluminium npuas suab rwb thaiv tsev thiab cov khoom siv suab nrov
Cov yam ntxwv tseem ceeb ntawm aluminium npuas acoustic panels:
1, high-tech, composite ua npuas ncauj aluminium phaj, zoo acoustic kev ua tau zoo, acoustic barrier, lub teeb yuag, zoo nkauj, fireproof, tsis ntshai dej, zoo lub cev muaj zog, yooj yim ua, ua los ntawm nws mus rau hauv ntau hom suab-absorbing lub cev, muffler , suab rwb thaiv tsev qauv, suab barrier, muffler chav tsev, suab rwb thaiv tsev npog, thiab lwm yam., tuaj yeem ncaj qha rau ntawm lub suab nrov, tsis muaj kev tiv thaiv vaj huam sib luag thiab lwm yam suab-absorbing muab tub lim.
2, Nws muaj kev ua tau zoo acoustic: nruab nrab suab nqus coefficient ≥0.60 (125-4000Hz zaus ntau); lub caij no, nws muaj kev ua tau zoo acoustic uas lub suab nqus kev ua haujlwm tsis hloov tom qab txau dej thiab txau tshauv ntawm lub rooj tsavxwm.
3, ua npuas ncauj aluminium phaj los ntawm aluminium alloy tuag-casting molding, tawg, txhua yam tuaj yeem siv dua, tam sim no tsis muaj kev ua qias tuaj rau ib puag ncig ntawm cov khoom siv high-tech ntsuab.
