ʻO ka Nickel foam kahi mea kupaianaha i loaʻa i ka manaʻo ākea i nā ʻoihana like ʻole ma muli o kāna mau waiwai kūʻokoʻa a me ka laulā o nā noi. ʻO kēia mea porous a me ka conductive mea i hōʻoia i ka waiwai nui ma nā ʻano ākea, mai ka mālama ʻana i ka ikehu a me ka hoʻololi ʻana i ka kānana a me ka catalysis. Ma kēia blog, e ʻimi mākou i ka honua hoihoi o ka nickel foam a me kona hiki ke hoʻololi i nā ʻenehana he nui.

Hōʻuluʻulu kēia pepa i nā waiwai maikaʻi loa o nā metala foam a me nā kikoʻī i nā hopena o ka hoʻomohala ʻana i kēia manawa o nā metala foam, ʻoi aku ka titanium foam, e like me ka aerospace impact resistant material, biomedical material, kiʻekiʻe-mehana kānana meahana a me nā mea pākaukau, a me nā mea ʻē aʻe. nā wahi e kūkulu ʻia.

ʻO ka pahu alumini e hoʻohui i nā mea hoʻohui i loko o ka alumini maʻemaʻe a i ʻole nā ​​​​palapala alumini, ma hope o ka hoʻoulu ʻana i loko, me ka noʻonoʻo ʻana i nā ʻano o nā mea metala a me nā ʻōpala. Loaʻa iā ia ka haʻahaʻa haʻahaʻa, ke kūpaʻa hopena kiʻekiʻe, ke kūpaʻa wela, ka palekana ahi, ka pale ʻana i ka corrosion, ke kani ʻana o ke kani, ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, ka mea pale magnetic maikaʻi, ke kūpaʻa ʻelemakule ikaika, ka mana kānana, maʻalahi e hana, maʻalahi e hoʻokomo, kiʻekiʻe precision molding, a hiki ke hana ma ka ili o ka pena.

ʻO Nickel foam kahi mea paʻa loa, haʻahaʻa haʻahaʻa, ʻekolu-dimensional reticulated foam metala, he mea hou a wikiwiki hoʻi i ka ʻepekema waiwai o kēia manawa. Hāʻawi ka hoʻolālā foam i ka metala nickel i kahi hoʻolālā open-cell, e hāʻawi iā ia i ka permeability maikaʻi loa a me ka hoʻoili wela nui a me nā waiwai dissipation.
Hana ʻia ʻo Nickel foam ma ka electroplating ma luna o ka iwi o nā polymers kūikawā me kahi ʻano pūnaewele ʻekolu-dimensional, e like me ka polyurethane, polyester polyurethane a me nā polymers kūikawā (sponges). Ma hope o ka hoʻopaʻa ʻana, hana ʻia ka huahana metala hope loa ma ke puhi ʻana i ka mea polymer kūloko a me ka hoʻohaʻahaʻa ʻana i nā oxides metala, a hana ʻia me ka mechanically e ka mālama wela kemika.
ʻO Nickel foam, me kāna mau mea māmā a me ka uila uila, ʻo ia kekahi o nā poloka kūkulu nui o nā hydrogen electrolyzers o AEM, e hāʻawi ana i kahi hopena kūpono no ka hana hydrogen kūpono a hoʻomau.

ʻO nā ʻokoʻa nui ma waena o nā panela foam alumini a me ka veneer alumini ko lākou mea, mānoanoa, kaumaha, ikaika, pale ahi, a me ka laulā o ka hoʻohana.

Hoʻokomo ʻia nā ʻūhā metala i nā noi ʻenehana ma muli o ko lākou haʻahaʻa haʻahaʻa, kiʻekiʻe leo ratio a me ke kiʻekiʻe thermal conductivity. I loko o ka ʻoihana hoʻomehana a me ka hoʻoluʻu, nā mea hoʻololi wela paʻa, nā hale wela o ka lā a me ka mālama ʻana i ka ikehu wela ka 3 kuhikuhi kumu.

ʻO ka Nickel foam kahi mea kani maikaʻi loa me ka helu hoʻonui kiʻekiʻe i nā alapine kiʻekiʻe; hiki ke hoʻomaikaʻi ʻia kāna hana kani kani i nā alapine haʻahaʻa e ka hoʻolālā ʻana o ka hoʻolālā kani. ʻO Nickel foam kekahi o nā mea electrode maikaʻi loa no nā pihi cadmium-nickel a me nā pākahi hydrogen-nickel. He nui nā hiʻohiʻona maikaʻi loa o ka Nickel foam ponoʻī.

Ua hoʻomākaukau ʻia ka pahu metala e ka sintering, electroplating, kaomi hoʻolei ʻana, a me nā ʻano hana hoʻohua. I waena o lākou, ʻo ke ʻano electroplating a me ke ʻano metallurgy pauka ma lalo o ka mahele o ke ʻano foaming he mea maʻamau. ʻO ka mea mua ma ka hoʻohui ʻana i ka mea hoʻohua i ka metala i hoʻoheheʻe ʻia e hana i ka huʻa metala; ʻo ka hope ma o ke kaʻina hana electrodeposition i loko o ka pūpū polyurethane i kope ʻia i loko o ka pahu metala. I kēia manawa, ua hoʻohana nui ʻia ka pahu metala i ka nickel aluminika, ke keleawe a me kāna mau alloys, me ka hao, ka magnesium, ka titanium, ke kila, ke alakaʻi a me nā mea ʻē aʻe i loaʻa kekahi wahi noi.

ʻO ka pahu metala kahi mea metala me nā waiwai kūikawā, nona nā waiwai metala a me nā waiwai, no laila ua kapa ʻia ka inoa metala. No laila, he metala paha ka ʻūhā metala?
ʻAe ka pane. Hana ʻia ka pahu metala i nā mea metala, nona nā waiwai o ka metala e like me ka uila conductivity, thermal conductivity, ikaika a pēlā aku. I ka manawa like, he nui ka nui o nā pores liʻiliʻi i loko o ka pahu metala, e hana ana i kahi ʻano like me ka foam, ka mea e hana ai ka pahu metala i nā waiwai o ke kaumaha māmā, ka ikaika kikoʻī kiʻekiʻe, ka insulation wela maikaʻi a pēlā aku.

He ʻano ʻokoʻa ka ʻōhua metala, e hui pū ana i nā ʻano metala a me nā waiwai hana o nā mea porous. ʻO ka pahu metala no nā mea metala porous, hiki ke kiʻekiʻe ka porosity o loko e like me 90% a i ʻole, ʻo ke ʻano like me ka "foam" a i ʻole "honeycomb", e uhaʻi ana i ka manaʻo kuʻuna o ke ʻano o ka metala, nā ʻano metala "ikaika" ʻelua. a me nā hiʻohiʻona "māmā", he hana hou i hoʻohui ʻia o nā mea metala. "Ua haki ia i ka manaʻo kuʻuna o ka ʻano metala paʻa a loaʻa nā ʻano ʻelua o ka metala a me ka bubble, kahi ʻano mea metala hou me ka hoʻohui ʻana i ka hana.
