Nā waiwai waiwai, nā ʻano a me nā manaʻo no ka hoʻohana ʻana i ka pahu metala

ʻO ke ʻano o nā ʻōhua metala
I kēia manawa, ʻo ke ʻano o ka hoʻomākaukau nui ʻana o ka metala foamed ʻo ke ʻano sintering, electroplating method, pressure casting method and foaming method. Eia mākou e hoʻolauna pōkole i nā mea mua ʻekolu:
ʻŌhā aluminia me kona mau huila:he māmā i ka maikaʻi a loaʻa iā ia nā hiʻohiʻona o ka insulation wela, ke kani kani, ka pale electromagnetic, a me ka absorption o ka ikehu hopena. Hoʻohana nui ʻia ia i nā papa pale pale o nā missiles, mokulele, a me kā lākou mau mea i hoʻihoʻi ʻia. Eia kekahi, hiki iā mākou ke ʻike iā ia ma nā kahua o nā kaʻa kaʻa, nā mīkini hoʻoheheʻe uila, nā pale uila electromagnetic hāʻawi mana pulsed, etc.
ʻĀpana nikela:Me kona hoʻohui ʻana i ka pore a me ka porosity kiʻekiʻe, hana maikaʻi ia ma ke ʻano o ka ventilation kiʻekiʻe, kahi kikoʻī kikoʻī kiʻekiʻe a me ka ikaika capillary. Hoʻohana maʻamau ia i ka hana ʻana i nā kānana wai, catalysts, atomizers, nā pā uila uila a me nā mea hoʻololi wela.
Puhu keleawe: Loaʻa iā ia ka conductivity uila maikaʻi a me ka ductility. Ke hoʻohālikelike ʻia me ka nickel foam, ʻoi aku ka haʻahaʻa o ke kumukūʻai hoʻomākaukau a ʻoi aku ka maikaʻi o ka conductivity uila. Loaʻa iā ia ka ʻōlelo hoʻohiki maikaʻi i ka hoʻomākaukau ʻana i nā mea electrode maikaʻi ʻole (carrier), nā mea lawe catalyst a me nā mea pale electromagnetic. Eia naʻe, ʻaʻole maikaʻi ka ʻūhā keleawe e like me ka nickel ma muli o kona kūpaʻa ʻana i ka corrosion, e kaupalena ana i kāna wahi noi.
Ka hoʻohana ʻana i ka pahu metala
Ua hoʻohana nui ʻia ʻo Metal foamed i kahi ʻano o ka hoʻomohala ʻana i nā ʻoihana e like me ka aerospace, ka mālama ʻana i ke kaiapuni petrochemical, ke kūkulu ʻana a me ka pale ʻana i ka halihali. E like me nā pilikia i manaʻo ʻia, hoʻokaʻawale mākou i ke kuhikuhi noi o ka metala foamed i ʻehā mau ʻaoʻao nui.：
kino lamina:No ka meahuʻa metalaLoaʻa i kekahi ikaika, ductility, a me ka haʻahaʻa haʻahaʻa a me ke kaumaha, hoʻohana maʻamau ia i ka hana ʻana i nā ʻano mea like ʻole laminated composite, a hoʻohana nui ʻia i ka hana ʻana i nā coils māmā e lawe ana i nā panela, nā hale, a me nā kino paipu. Hoʻohana nui ʻia ia. E like me ke kumu kumu o nā ʻāpana clamping i hoʻohana ʻia i nā mokulele, nā hale neʻe, nā moku ākea, nā sleds, etc.
Kākoʻo kino:He māmā a paʻakikī hoʻi ka plastic plastic, me ka hiki ke lawe maikaʻi a me ka hana hoʻoili wela. He nui nā noi i loko o nā hale ʻēheu, missile nose stacks, spacecraft landing gear, etc. no ka hoʻoikaika a me ke kākoʻo ʻana i kekahi mau pūpū cylindrical pā lahilahi.
Cushioning a me ka haʻalulu ʻana:hiki i ka pahu metala ke komo i ka ikehu, hiki ke hoʻemi i ka ikaika o waho o ka mea i kahi pae palekana. Ma ka hoʻoponopono ʻana i ka nui o ka pahu metala, hiki ke hopu ʻia kona ikaika, a hiki ke hoʻopili ʻia i ka noi cushioning o nā ʻano like ʻole. o na mea.A he mea pono e olelo aku ia malalo o ka hana o ke kaumaha mau, kahuʻa metalahiki ke pale i ka nui o ka compressive strain a hiki ke komo i ka ikehu nui. No ka laʻana, i ka hana ʻana i nā iwi artificial, ʻaʻole i loaʻa wale nā ​​waiwai mechanical kiʻekiʻe o ka pahu metala, akā hoʻokō pū i ka porosity nui e pono ai no nā iwi kanaka.
Hoemi ka halulu:Loaʻa i ka ʻūhā metala ke kani maikaʻi a me nā hopena insulation kani. Hoʻohana ʻia ia i ka hoʻohaʻahaʻa ʻana i ka walaʻau ala nui, nā ʻenekini hoʻoheheʻe kūloko kūloko, nā lumi hana mana kaʻaahi kiʻekiʻe, ka hoʻopaʻa lekiō, etc.
Ma ke ʻano he mea hou,metala huʻaloaʻa i ka hana maikaʻi loa ma ke ʻano o ke kumukūʻai a me ka pono. Ma lalo o ke au hoʻomohala o kēia manawa o ka ʻepekema a me ka ʻenehana, ʻoi aku ka ikaika o ka hoʻomākaukau ʻana a me ka hoʻonui ʻia ʻana o ke kahua noiʻi o ka metala foamed, a ʻo ka hoʻomohala ʻana i ka wā e hiki mai ana ke nānā i mua.
