Aluminium Foam High-Efficiency Acoustic Vaj Huam Sib Luag Tunnel Suab Deadening thiab txo suab nrov
Product Description:
Kaw-cell ua npuas ncauj aluminium panels yog tsim rau hauv high-efficiency suab-absorbing panels tom qab perforation kev kho mob (Φ2mm qhov, perforation tus nqi ntawm 1-3%), uas muaj zoo heev suab-absorbing kev kawm, thiab lub suab-absorbing tus nqi yuav ncav cuag 60%. mus txog 90%. Txij li qhov saum npoo ntawm cov khoom no tsis muaj dav hlau, nws muaj qhov zoo tshaj plaws ntawm qhov sib txawv ntawm lub suab nrov, thiab tib lub sijhawm, nws muaj lub suab nqus dej ntawm perforated Helmholtz resonance acoustic absorber, uas ua kom lub suab nrov zoo. Tsis tas li ntawd, nyob rau hauv qhov chaw ntub dej, cov khoom siv acoustic zoo tib yam absorbs dej thiab nthuav dav, lub suab nqus coefficient txo qis heev, thaum cov khoom siv txhuas ua npuas dej tsis nqus dej, nws lub suab nqus tsis txo qis.
Aluminium ua npuas ncauj phaj tom qab txheej txheej thickness ntawm huab cua txheej, lub ntsiab zaus ntawm lub suab nqus yog txawv, nrog lub thickness ntawm cov huab cua txheej los ntawm 0mm mus rau 90mm, lub ntsiab zaus ntawm lub suab nqus los ntawm 2000Hz mus rau 300Hz los yog li ntawd. Thaum lub thickness ntawm cov huab cua txheej yog 10, 30, 60, 90mm, lub ntsiab zaus ntawm lub siab tshaj plaws suab haum tus nqi yog 1000Hz, 500Hz, 400Hz, 300Hz los yog li ntawd. Raws li lub suab nrov zaus tis tsim ua npuas ncauj tus nqi acoustic vaj huam sib luag tom qab huab cua txheej thickness. Txoj kev loj, hauv qab dej tunnels, undersea tunnels thiab lwm lub tsheb tsim lub suab nrov nrov zaus ntawm 400Hz, rau cov suab nrov tsawg zaus, yog li txoj kev loj suab teeb meem, nyob rau hauv dej thiab undersea tunnels suab-absorbing phab ntsa aluminium foam acoustic panels qab qhov chaw ntawm 60 hli tuab huab cua txheej, suab nrov txo cov nyhuv yog zoo. Railroad suab nrov yog nruab nrab thiab siab zaus suab nrov tshaj 1000Hz, 20mm tuab cua txheej yog teem tom qab aluminium foam sound-absorbing phaj nrog zoo suab nrov txo.
