Hunhu hukuru hwealuminium foam acoustic mapaneru:
1, high-tech, composite foam aluminium plate, yakanaka acoustic performance, acoustic barrier, lightweight, yakanaka, isingapindi moto, isingatye mvura, yakanaka yemuviri zvivakwa, nyore kugadzirisa, yakagadzirwa nayo kuita akasiyana siyana emuviri unonzva inzwi, muffler. , ruzha rwekuvharidzira chimiro, chinovhara ruzha, muffler kamuri, ruzha rwekuvhara chivharo, nezvimwewo, inogona kutarisana zvakananga neruzha sosi, pasina chero chekudzivirira uye imwe inopfeza-inotora kuzadza.
2, Iyo ine yakanakisa acoustic performance: avhareji inzwi absorption coefficient ≥0.60 (125-4000Hz frequency renji); Zvichakadaro, ine yakanakisa acoustic performance iyo inonzwika absorption kuita haichinji mushure mekupfapfaidza mvura nekupfapfaidza madota pabhodhi.
3, foam aluminium plate nealuminium alloy die-casting molding, yakaputsika, inogona kudzokororwa, parizvino hapana kusvibiswa kwechipiri kune nharaunda yegirinhi yepamusoro-tech zvigadzirwa.
