Nā ʻano maʻamau o nā pale kani

E like me ka hoʻokaʻawale ʻana o nā mea, hiki ke hoʻokaʻawale ʻia ka pale kani i loko o nā ʻāpana aʻe: ka pale kani metala (nā pani metala, ka pahu alumini), ke kani ʻana o ke kani (ka māmā māmā, ka ikaika kiʻekiʻe), ka pale kani PC, ka pale kani FRP, etc.

Ke hoʻohālikelikeʻia me nā mea kani kani maʻamau, e like me ka huluhulu aniani a me ka asbestos, loaʻa i ka pahu alumini nā hiʻohiʻona o ke kākoʻo pono'ī, ka pale wela kiʻekiʻe,ʻaʻohe hoʻokuʻuʻana i nā kinoea kino, ka haʻahaʻa haʻahaʻa haʻahaʻa a me ka maikaʻi o ka wā. He mana nui kona. He hanauna hou o nā mea kani. No laila, hoʻohana nui ʻia ia ma ke kahua o ka hoʻohaʻahaʻa ʻana i ka walaʻau a me ka ʻenekinia mālama kaiapuni, e like me ka hana ʻana i nā pale kani kiʻekiʻe, nā paia hoʻoheheʻe kani, etc.

ʻO nā pōmaikaʻi o ka pale kani alumini foam

Hoʻokumu ʻia ka ʻūhā alumini ma ka hoʻohui ʻana i nā mea hoʻohui i ka alumini maʻemaʻe a i ʻole ka alumini alumini a laila e hana ʻia i kahi kaʻina hana hū. I ka manawa like, loaʻa iā ia nā ʻano metala a me nā ʻōpū. He ʻano mea hou ia o nā mea kani porous.

ʻO nā mea maikaʻi o nā pale kani alumini foam ka mea nui i nā ʻano aʻe:

1. Hana maikaʻi loa i ke kani kani

He paʻa ka hana hoʻoheheʻe leo o ka alumini foam, ʻoi aku ka nui o ka nui o ka leo absorption ma mua o 0.64, a ʻo ka helu hoʻemi o ka walaʻau e pili ana i ka NRC0.75. I ka ua a i ʻole ma hope o ka lawe ʻana i ka lepo, ʻaʻole e loli ka coefficient absorption kani, e hoʻokō i nā koi acoustic o nā pale kani alanui.

2. maʻalahi e hoʻouka

Hana ʻia ka pahu kani alumini i ka alumini maʻemaʻe, a hiki ke hōʻike pololei ʻia ka papa hoʻoheheʻe ʻana i ka leo alumini i ka lewa, me ka ʻole o ka pono o ka papa hoʻomaʻamaʻa, anti-corrosion layer a me ka filler, etc., a ua maʻalahi. e hoʻouka.

3. Maʻalahi e mālama a lōʻihi ke ola

Hiki ke holoi ʻia nā panela e like me ke aniani, a hiki ke hoʻomaʻemaʻe iā ia iho ma o ka ua maoli. ʻOiai inā e hōʻiliʻili ka lepo, ʻaʻole ia e hoʻopilikia i kāna hana acoustic, akā e hoʻomaikaʻi i ka hana hoʻoheheʻe kani kiʻekiʻe. I ka manawa like, he maikaʻi ke kū'ē i ka wā, ke kū'ē i ka corrosion a me ke kū'ē kahiko, a hiki i ke ola lawelawe ke hiki i nā makahiki he 30.

4. Nā hiʻohiʻona maʻamau, ka'ōmaʻomaʻo a me ka palekana o ke kaiapuni

Hiki ke hoʻopili ʻia ka ʻili o ka pahu alumini me ka fluorocarbon, a hiki ke hoʻopili ʻia ke kala e like me nā pono o ka mea hoʻohana; ʻO ka pahu alumini he A1 pale ahi, ʻōmaʻomaʻo a me ka pollution-free, ʻaʻole e hoʻokuʻu i nā mea ʻino i nā wela kiʻekiʻe, a hiki ke hana hou ʻia a hoʻohana hou ʻia.

ʻO ke ʻano maʻamau o ka pahu kani alumini

1. "pane hoʻopaʻa leo alumini foam + panel hope metala"

Hoʻohana pololei ʻia ka papa alumini foam composite sound-absorbing board e like me ka panel (haʻihaʻi haʻahaʻa> 1000N, hiki i ka ʻili ke halihali i ka ukana 1500N/m2; deflection 0.089

2. “Pane Aluminum hu‘ihu‘i po‘i po‘i + panel ho‘opa‘a leo alumini + panel hope metala”

Hoʻohana ʻia ka papa alumini foam composite e like me ka papa sandwich waena, no laila hiki i ka pahu alumini ke 5mm-7mm mānoanoa, ʻaʻohe hopena i ka mana hoʻoheheʻe kani a hoʻemi i ke kumukūʻai; ʻO ka papa hoʻoheheʻe leo alumini ka mea hoʻoheheʻe leo o 0.75, hiki ke hoʻokō i nā pono o nā viaducts o ke kūlanakauhale ma ka laulā o 200-4000Hz ʻO ka coefficient absorption leo e koi ʻia e ke kūlana pale kani hiki ke hana i kahi lua resonant ma kahi o 50mm, ʻo ia ka mea e hoʻomaikaʻi hou ai i ka hopena hoʻoheheʻe kani ma kahi o 3dB.

3. "Panel + kino hoʻoheheʻe leo composite (pahu alumini + mea hoʻoheheʻe kani ʻē aʻe) + panel hope o ka lua"

I ka ʻike ʻana i ka ʻoi aku o ka mānoanoa o ka paneli hoʻoheheʻe leo alumini, ʻoi aku ka maikaʻi o ka ikaika a me ka hopena insulation leo, akā ʻo nā kino o luna a me lalo ke pāʻani nei i ke ʻano o ke kani kani. Hiki i ka Yante Material Technology (Luoyang) Co., Ltd. ke hoʻohana i ka hoʻolālā ʻana o ka ʻaoʻao o ka papa hope o nā panela hoʻoheheʻe kani + nā ʻāpana ʻeleʻele alumini ʻeleʻele a me nā mea kani ʻē aʻe e hana ai i nā kino kani + nā pono maoli o nā mea hoʻohana, e hāʻawi ana i nā mea hoʻohana me ka hoʻolālā papa hoʻolālā leo hoʻoheheʻe i ka moe kolohe.

Aluminum pahu kani pale

ʻO ka helu hoʻoheheʻe leo o ka pahu pahu pahu alumini ma luna o 0.45, a hiki i ka coefficient absorption leo ke piʻi ma luna o 0.75 ma hope o ka perforation a me ke kaomi.

Hiki ke hoʻohana nui ʻia ma nā alanui, nā alahao a me nā ala ala o ke kūlanakauhale.

Eia kekahi, hiki ke hoʻohana ʻia nā pale leo alumini no nā paia kūpaʻa ma lalo o nā curbs platform o nā keʻena kaʻaahi a me nā paia tunnel e pili ana, luna a me ʻelua ʻaoʻao o nā tunnel station, hoʻokele a me nā keʻena lako, nā hale hoʻomaha hoʻomaha ʻāina a me nā kumu ea, a me ke alaloa. ventilation Silencers, haʻalulu a me ka leo ho'ēmi i loko o ke kaʻaahi depots, soundproof lumi, KTV, hale kiʻiʻoniʻoni, loko 'auʻau loko, basketball stadiums a me kekahi mau kula.
