ʻO ka hoʻohana nui ʻana i nā huahana graphite

Hiki i nā huahana graphite ke hoʻokuʻu i nā kukuna infrared mamao ma hope o ka hoʻomehana ʻana.

ʻO ka pōhaku magnesium-carbon refractory ʻO ka waena o ke au, i hoʻomohala ʻia e ʻAmelika Hui Pū ʻIa, ua hoʻomaka ka ʻoihana hana kila Kepani e hoʻohana i ka pōhaku magnesium-carbon no ka hoʻoheheʻe ʻana i ka umu arc hoʻoluʻu wai. Ua hoʻohana nui ʻia nā pōhaku magnesia-carbon i ka hana kila ma ka honua holoʻokoʻa a ua lilo i hoʻohana kuʻuna o ka graphite. I ka hoʻomaka ʻana o ke kenekulia he ʻumi, ua hoʻomaka ka hoʻohana ʻana i nā pōhaku magnesium-carbon no ka uhi ʻana o ka mea hoʻololi oxygen top-blown.

Hoʻohana nui ʻia nā mea paʻa kalapona aluminika i ka hoʻolei mau ʻana, ka uhi paipu hoʻonoho ponoʻī kila palahalaha, ka nozzle lalo o ka wai a me ka cylinder pahū ʻaila. ʻOi aku ka nui o ke kila i hana ʻia ma o ka hoʻolei mau ʻana ma Iapana ma mua o ka huina o ka hana.

ʻO nā huahana ipu hao a me nā huahana pili i hana ʻia me ka hoʻoheheʻe graphite a me nā ipu hao refractory a me nā huahana pili, e like me ka ipu hao, ka ʻōmole ʻāʻī piʻo, ka plug a me ka nozzle, a pēlā aku, he kiʻekiʻe ke kūpaʻa ahi, hoʻonui haʻahaʻa thermal, ka hoʻoheheʻe ʻana i ka metala, ma o ka infiltration metala a me ka erosion he paʻa nō hoʻi, maikaʻi ke kūpaʻa thermal shock i ka mahana kiʻekiʻe a me ka conductivity maikaʻi loa, No laila, hoʻohana nui ʻia ka ipu hao graphite a me kāna mau huahana pili i ke kaʻina hana o ka hoʻoheheʻe pololei ʻana o ka metala. Hana ʻia ka ipu hao lepo graphite kuʻuna me ka ʻike kalapona ʻoi aku ka nui ma mua o ka graphite unahi, ʻoi aku ka nui o ka unahi graphite ma mua o ka mesh (- screen), a ʻo ka hoʻomaikaʻi koʻikoʻi i ka ʻenehana hana ipu hao haole ʻo ia ka ʻano o ka graphite i hoʻohana ʻia, ka nui unahi a me ka maikaʻi he ʻoi aku ka maʻalahi a ukali ʻia e ka hoʻohana ʻana i ka ipu hao graphite silicon carbide ma kahi o ka ipu hao graphite lepo kuʻuna. ʻO kēia ma muli o ka hoʻolauna ʻana o ka ʻenehana kaomi mau i ka ʻoihana kila. ʻO ka hoʻohana ʻana i ka ʻenehana kaomi mau hiki ke hana i ka graphite liʻiliʻi hiki ke hoʻopili ʻia, i loko o ka ipu hao graphite lepo, a i loko o ka ipu hao graphite silicon carbide, ʻo ka ʻike o nā ʻāpana nui wale nō ka helu, a ua hoʻemi ʻia ka ʻike kalapona o ka graphite.

hana kila

Hiki ke hoʻohana ʻia ka graphite a me nā mea haumia ʻē aʻe e like me nā carburizers i ka ʻoihana hana kila. Hoʻohana ka carburizing i nā ʻano mea kalapona like ʻole, me ka graphite artificial, petroleum coke, metallurgical coke a me ka graphite kūlohelohe. ʻO Graphite kekahi o nā hoʻohana nui o ka graphite e like me ka honua ma ka honua.

Mea alakaʻi

Hoʻohana nui ʻia ka Graphite i ka ʻoihana uila e like me nā electrodes, brushes, carbon rods, carbon tubes, mercury rectifiers, graphite gaskets, nā ʻāpana kelepona, ka uhi ʻana i nā kiʻi kiʻi kīwī a pēlā aku. I waena o lākou, ʻo ka electrode graphite ka mea i hoʻohana nui ʻia, i ka hoʻoheheʻe ʻana i nā kila alloy like ʻole, ka hao alloy, ka hoʻohana ʻana i ka electrode graphite, a laila he au ikaika ma o ka electrode i loko o ka wahi hoʻoheheʻe umu, e hana i kahi arc, i mea e lilo ai ka ikehu uila i ikehu wela, piʻi ka mahana i kahi, i mea e hoʻokō ai i ke kumu o ka hoʻoheheʻe ʻana a i ʻole ka hopena. Eia kekahi, i ka wā e electrolyzing ai i ka magnesium, alumini a me ka sodium, hoʻohana pū ka anode o ke kelepona electrolytic i kahi electrode graphite. Hoʻohana pū ʻia ka electrode graphite ma ke ʻano he mea alakaʻi o ke poʻo umu no ka hana ʻana i nā umu pale abrasive. Loaʻa i ka graphite i hoʻohana ʻia i ka ʻoihana uila nā koi kiʻekiʻe no ka nui o ka ʻāpana a me ke ʻano. E like me nā pila alkaline a me kekahi mau huahana kalapona uila kūikawā, pono e hoʻomalu ʻia ka nui o ka ʻāpana graphite i loko o ka laulā o ka papahana, aia ke ʻano ma luna, a pono e emi nā haumia ʻino (ʻo ka hao metala) ma lalo. Loaʻa i ka graphite i hoʻohana ʻia i loko o ka TV kiʻi kiʻi nā koi nui o ka ʻāpana. Hoʻohana pinepine ʻia ka graphite ma ke ʻano he lubricant i ka ʻoihana mīkini. ʻAʻole hiki ke hoʻohana pinepine ʻia ka ʻaila lubricant ma lalo o ka wikiwiki kiʻekiʻe, ke ana wela kiʻekiʻe, nā kūlana kaomi kiʻekiʻe, a hiki i nā mea pale graphite ke hana me ka ʻole o ka ʻaila lubricating ma ka mahana - a ma ka wikiwiki paheʻe kiʻekiʻe loa. He nui nā lako lawe media corrosive, hoʻohana nui ʻia nā mea graphite i hana ʻia me nā apo piston, nā sila a me nā bearings, i ka wā e holo ai, ʻaʻole pono e hoʻohui i ka ʻaila lubricating, he lubricant maikaʻi nō hoʻi ka waiū graphite no nā hana metala he nui (kaha kiʻi uea, kaha kiʻi paipu).

Mea kū i ka palaho

He kūpaʻa kemika maikaʻi ko Graphite. Loaʻa i ka graphite i hana kūikawā ʻia nā ʻano o ke kūpaʻa ʻana i ka pala, ka conductivity thermal maikaʻi a me ka permeability haʻahaʻa, a hoʻohana nui ʻia i ka hana ʻana o nā mea hoʻololi wela, nā pahu hopena, nā condensers, nā hale kiaʻi kuni, nā hale kiaʻi absorption, nā mea hoʻoluʻu, nā mea hoʻomehana, nā kānana, nā pamu a me nā lako ʻē aʻe. Hoʻohana ʻia kēia mau lako i ka petrochemical, hydrometallurgy, hana waikawa a me alkali, fiber synthetic, pepa a me nā ʻoihana ʻē aʻe, hiki ke mālama i ka nui o nā mea metala. 0 No ka hoʻolei ʻana, ke one ʻana, ke kaomi ʻana a me nā mea metallurgical wela kiʻekiʻe ma muli o ke coefficient hoʻonui liʻiliʻi o ka graphite, a me ka hiki ke hoʻololi i ke anuanu a me ka wela, hiki ke hoʻohana ʻia e like me ka ʻōmole aniani, ma hope o ka hoʻohana ʻana i ka graphite, loaʻa i nā hoʻolei metala ʻeleʻele ka nui pololei, ʻili laumania, hua kiʻekiʻe, hiki ke hoʻohana ʻia me ka ʻole o ka hana ʻana a i ʻole ka hana iki ʻana, no laila e mālama ana i ka nui o ka metala. ʻO ka hana ʻana o ka carbide a me nā kaʻina hana metallurgy pauka ʻē aʻe, i hana pinepine ʻia me nā mea graphite no ke kūpaʻa ʻana i ke kaomi i ka sintering o nā waʻa. ʻO ka ipu hoʻoulu kristal silicon monocrystalline, ka ipu hoʻomaʻemaʻe ʻāpana, bracket, fixture, induction heater, etc., ua hana ʻia me ka graphite maʻemaʻe kiʻekiʻe. Eia kekahi, hiki ke hoʻohana ʻia ka graphite ma ke ʻano he papa insulation graphite vacuum metallurgy a me ke kumu, ka paipu umu umu wela kiʻekiʻe, ke koʻokoʻo, ka papa, ka grid a me nā ʻāpana ʻē aʻe.

Ikehu ʻātoma

Loaʻa i ka Graphite ka hana hoʻēmi neutron maikaʻi, ʻo ka mea mua i hoʻohana ʻia ma ke ʻano he moderator i nā reactors atomika, ʻo ka uranium-graphite reactor kahi reactor atomika i hoʻohana nui ʻia. Ma ke ʻano he mana no ka ikehu atomika, pono e loaʻa i kahi kiko heheʻe kiʻekiʻe, kūpaʻa, kū'ē i ka palaho, hiki i ka graphite ke hoʻokō piha i nā koi i luna. He kiʻekiʻe loa ka maʻemaʻe o ka graphite i hoʻohana ʻia ma ke ʻano he reactor atomika, a ʻaʻole pono e ʻoi aku ka nui o ka haumia ma mua o nā ʻumi (hoʻokahi ʻāpana no ka miliona), ʻoi aku ka liʻiliʻi o ka boron.

Mea anti-fouling a me anti-rust

Hiki i ka Graphite ke pale i ka scaling boiler, hōʻike nā hoʻokolohua ʻāpana pili e hiki i ka hoʻohui ʻana i kahi nui o ka pauka graphite i loko o ka wai (e pili ana i kēlā me kēia tona o ka wai) ke pale i ka unahi ma ka ʻili o ka boiler. Eia kekahi, ʻo ka graphite i hoʻopili ʻia i nā lua ahi metala, nā hale, nā alahaka, nā paipu hiki ke pale i ka corrosion a me ka rust.

Nā hoʻohana ʻē aʻe

Me ka hoʻomohala mau ʻana o ka ʻepekema a me ka ʻenehana, ua hoʻomohala ka poʻe i nā hoʻohana hou he nui no ka graphite. Nā huahana graphite maʻalahi. ʻO ka graphite maʻalahi, i ʻike ʻia hoʻi ʻo graphite hoʻonui ʻia, he huahana graphite hou i hoʻomohala ʻia i nā makahiki 1990. Ua noiʻi pono ʻo ʻAmelika Hui Pū ʻIa i nā mea sila graphite maʻalahi e hoʻoponopono i ka pilikia leakage o nā valves ikehu atomika, a laila hoʻomaka ʻo Kelemania, Iapana a me Palani e hoʻomohala a hana. Ma waho aʻe o nā ʻano o ka graphite kūlohelohe, loaʻa i kēia huahana ka maʻalahi a me ka elasticity kūikawā. No laila, he mea sila kūpono ia. Hoʻohana nui ʻia i ka petrochemical, ka ikehu atomika a me nā ʻoihana ʻē aʻe. Ke piʻi nei ke koi o ka mākeke honua i kēlā me kēia makahiki.

Hoʻohana ʻia nā huahana maʻemaʻe kiʻekiʻe i ka hoʻoheheʻe ʻana i ka metala maʻemaʻe kiʻekiʻe, ʻoihana uila, ʻoihana nuklea a me ka hana ʻana i ka ʻōpala; Hoʻohana ʻia nā huahana maʻamau i loko o ka pahu electrolysis alumini, ka umu sintering metallurgy pauka, ka umu ferroalloy a me nā mea hana masonry umu mineral ʻē aʻe.

Hiki i kā mākou hui ke hāʻawi i nā mea kūʻai aku me nā ʻano huahana graphite mechanical like ʻole, e ʻoluʻolu ʻoe e hāʻawi i nā kiʻi i hoʻopilikino kūikawā ʻia. I kēia manawa, ua hoʻolako kā mākou hui i nā huahana bushing graphite i hoʻopilikino ʻia no nā mea kūʻai aku kahiko, e like me nā kiʻi a me nā koi i hāʻawi ʻia e nā mea kūʻai aku kahiko, ka maikaʻi a me ka nui, i hoʻopau ʻia i ka manawa a hāʻawi ʻia e like me ka mea i hoʻohiki ʻia, me ka manaʻolana e lanakila i ka hilinaʻi o nā mea kūʻai aku hou aku me kā mākou ʻoihana a me ka pono.
