ʻO ka Metal Foam e pili ana i nā mea metala kūikawā me nā pores.

Loaʻa iā ia ka ea permeability kiʻekiʻe, aneane pili nā pores āpau, ʻo ka BET o nā pores ka nui a me ka liʻiliʻi bulk density.

Hoʻokaʻawale ʻana i ka huʻa metala

ʻO ka Metal Foam ka mea maʻamau e like me ka pahu alumini, ka pahu keleawe, ka pahu nickel a me nā mea ʻē aʻe.

ʻO ka pahu Aluminum me nā mea hoʻoheheʻe he māmā i ke kaumaha a loaʻa nāʻano o ke kani kani, ka wela wela, ka haʻalulu haʻalulu, ka haʻalulu ikehu absorption a me ka hawewe electromagnetic, a me nā mea'ē aʻe. electromechanical vibration reduction device, electromagnetic wave shielding cover of pulse power supply, etc.

Ma muli o ke ʻano o ka pore pili a me ka porosity kiʻekiʻe, he kiʻekiʻe ka hana kinoea nickel foam, kahi ākea kikoʻī kiʻekiʻe a me ka ikaika capillary. Hoʻohana nui ʻia ma ke ʻano he mea hana e hana ai i nā kānana wai, atomizers, catalytic converters, pā pākaukau a me nā mea hoʻololi wela.

ʻO ka pahu keleawe he conductivity maikaʻi a me ka ductility, haʻahaʻa haʻahaʻa ka uku hoʻomākaukau ma mua o ka nickel foam, a ʻoi aku ka maikaʻi o ka conductivity, no laila hiki ke hoʻohana ʻia i ka hoʻomākaukau ʻana i nā mea anode (carrier), nā mea lawe catalyst a me nā mea pale electromagnetic.

Ma keʻano kūikawā, hoʻohana ʻia ka pahu keleawe ma ke ʻano he kumu kumu o ka electrode pākaukau, nona nā pono kūpono. Eia naʻe, ʻaʻole maikaʻi ke kūpaʻa ʻana o ke keleawe e like me ka nickel, kahi e kaupalena ʻia ai kāna noi.

Nā mea hoʻohana ʻana i ka pahu metala

Loaʻa i nā mea hao metala kekahi ikaika, ductility a addability, a hiki ke hoʻohana ʻia e like me nā mea hana māmā. nā hale kākoʻo.No ka mea hiki ke welded, glued a electroplated ma luna o ka hale, hiki ke hana ia i loko o ka sanwiti amo lālā.E like me ke kākoʻo no ka metala pūpū o ka eheu, kākoʻo anti-collapse no ka cone ihu o ka missile (no ka maikaʻi o ka thermal conductivity) a me ka pae pae o ka mokulele, etc.

I ke kūkulu ʻana, pono ʻia ka huʻa metala e hana i nā mea māmā, paʻakikī, a me nā mea pale ahi, railings, a kākoʻo paha no kēia mau mea. ʻO ka hoʻohana ʻana i ka ikehu a me ka lawe ʻana i nā hiʻohiʻona e hōʻemi i ka hoʻohana ʻana i ka ikehu. hiki i nā pūpū ke pohō ke kau ʻia i nā ukana, akā inā kākoʻo ʻia ka pūpū e ka huʻa mau: nā wili, ʻoi aku ka ikaika o ka hale ma mua o ka pūpū waena i hoʻopaʻa ʻole ʻia o ke anawaena like a me ka nui.

He mea maʻalahi ka hoʻohua keleawe a maʻalahi hoʻi e deform, no laila kūpono ia no nā mea hoʻopaʻa.

Hiki ke hoʻohana ʻia nā ʻūhā metala e like me nā mea hoʻoikaika no ka nui o nā mea kūlohelohe, inorganic a me nā mea hao.

He kūpono loa ka metala foam e hoʻohana ʻia ma ke ʻano he mea ʻōwili māmā no ka lawe ʻana i nā ʻano panela, nā pūpū a me nā paipu e hana i nā ʻano like ʻole o ka laminated composites. i nā mokulele hou e hoʻohana i ke aniani a i ʻole ka carbon fiber composite ʻili. Ua hoʻokaʻawale ʻia kēia papa o ka ʻili mai ka resin honeycomb material e ka alumini metala a i ʻole ka pepa, a i ʻole e ka polima polymer paʻa e hāʻawi i ka panel sandwich ʻo ka ʻoʻoleʻa kūlou kikoʻī nui a me ka ikaika kulou kikoʻī. Ua hoʻonui ʻia ka ʻenehana like i nā noi ʻē aʻe kahi i hōʻike ʻia ai ke kaumaha: nā moku ākea, nā sled, nā moku heihei a me nā hale neʻe.

ʻO ka pale Buffer kekahi o nā mea nui e hoʻohana ai i nā ʻūhā metala, pono e loaʻa ka mana e komo i ka ikehu i ka wā e kāohi ana i ka ikaika kiʻekiʻe e hana ana i ka mea e pale ʻia ma lalo o ka palena o ka hōʻino ʻana.

Ua kūpono nā ʻōhū porous no ia mau noi. Ma ka hoʻomalu ʻana i kona ʻano pili, hiki ke hoʻoponopono ʻia ka ikaika o nā ʻōpala metala ma kahi ākea.
