ʻO nā hiʻohiʻona nui o nā panela acoustic foam alumini:
1, high-tech, composite foam aluminum plate, good acoustic performance, acoustic barrier, light weight, beautiful, fireproof, ʻaʻole makaʻu i ka wai, nā waiwai kino maikaʻi, hana maʻalahi, hana ʻia i loko o nā ʻano like ʻole o ke kino hoʻoheheʻe leo, muffler. , ka hale hoʻoheheʻe kani, ka pale leo, ka lumi muffler, ka uhi hoʻoheheʻe kani, a me nā mea'ē aʻe, hiki ke kū pololei i ke kumu o ka walaʻau, me kaʻole o ka pale pale a me nā mea hoʻopiha kani.
2、Ua loaʻa iā ia ka hoʻokō acoustic maikaʻi loa: awelika kani absorption coefficient ≥0.60 (125-4000Hz frequency range); i kēia manawa, loaʻa iā ia ka hana acoustic maikaʻi loa ʻaʻole e loli ka hana hoʻoheheʻe leo ma hope o ka hoʻoheheʻe ʻana i ka wai a me ka pīpī ʻana i ka lehu ma ka papa.
3, ʻo ka pahu alumini pā e ka alumini alumini make-casting molding, haki, hiki ke hana hou ʻia, i kēia manawa ʻaʻohe haumia lua i ke kaiapuni o nā huahana ʻenehana kiʻekiʻe.
