ʻO ka Molybdenum kahi metala refractory maʻamau ma muli o kona kiʻekiʻe hehee a me ka paila.Me ka modulus elastic kiʻekiʻe a me ka ikaika kiʻekiʻe i ka wela kiʻekiʻe, he mea matrix koʻikoʻi ia no nā mea hoʻolālā kiʻekiʻe.Piʻi mālie ka evaporation me ka piʻi ʻana o ka mahana, i hiki ai i ka molybdenum ke lilo i mea koʻikoʻi no ke kumu kukui uila a hoʻohana nui ʻia.Hoʻohana nui ʻia ka Molybdenum i nā ʻoihana like ʻole.E nānā kākou i nā hoʻohana nui o ka molybdenum!
ʻOihana hao a me ke kila
Ma ke ʻano he mea hoʻohui o ke kila, hiki i ka molybdenum ke hoʻomaikaʻi i ka ikaika o ke kila, ʻoi aku ka ikaika a me ka paʻakikī i ka wela kiʻekiʻe.E hoʻomaikaʻi i ka pale ʻana i ka corrosion o ke kila i loko o ka hopena acid-base a me ka metala wai;hoʻomaikaʻi i ka pale ʻana o ke kila a hoʻomaikaʻi i ka hardenability, weldability a me ka wela.ʻO ka Molybdenum kahi mea hana carbide maikaʻi, ʻaʻole i oxidized i ke kaʻina hana kila a hiki ke hoʻohana wale ʻia a i ʻole me nā mea hoʻohui ʻē aʻe.
uila uila
Molybdenum i maikai conductivity a me ke kiʻekiʻe wela waiwai, o ka oi aku me ka linear hoonui coefficient o ke aniani ua kokoke loa, ua hoʻohana nui 'ia i loko o ka hana o ka puʻupuʻu spiral filament kumu uea, alakai uwea, makau, bracket, lihi koʻokoʻo a me nā mea 'ē aʻe, i loko o ka vacuum. paipu ma ke ano he puka a me ke anode mea kokua.ʻO ka uea Molybdenum kahi uea electrode kūpono no ka mīkini mīkini EDM, hiki iā ia ke ʻoki i nā ʻano kila a me ka paʻakikī paʻakikī, ka hana ʻana i nā ʻāpana me ke ʻano paʻakikī, kāna hana hoʻokuʻu paʻa, a hiki ke hoʻomaikaʻi maikaʻi i ka pololei o ka make.
ʻoihana kaʻa
Loaʻa ka Molybdenum i ka hana wela kiʻekiʻe a me ka pale ʻana i ka corrosion, ikaika ka molybdenum a me ke kila hoʻopaʻa ʻana, no laila ʻo ia ka mea nui e hoʻoulu ai i ka wela i ka hana ʻana i nā ʻāpana kaʻa.Hiki ke piʻi aku ka nui o ka molybdenum ma mua o 99%, ʻo ka ikaika paʻa kokoke i 10 kg / mm².Hiki i kēia kaʻina hana ke hoʻomaikaʻi maikaʻi i ke kūpaʻa ʻana o ka ʻili abrasive a hāʻawi pū i kahi porous i hiki ke hoʻopili ʻia ka aila lubricating.Hoʻohana nui ʻia ia i ka ʻoihana kaʻa no ka hoʻomaikaʻi ʻana i ka hana o nā apo piston, nā apo synchronization, nā ʻōpala, a me nā ʻāpana ʻē aʻe, a no ka hoʻoponopono ʻana i nā crankshafts, nā ʻōwili, nā shafts, a me nā ʻāpana mechanical ʻē aʻe.
Nā mea wela kiʻekiʻe
Hoʻohana pinepine ʻia ka Molybdenum e hana i nā mea hoʻomehana a me nā mea hoʻolālā no nā umu wela kiʻekiʻe ma muli o kona maʻemaʻe kiʻekiʻe, ke kūpaʻa kiʻekiʻe o ka wela a me ke kaomi haʻahaʻa haʻahaʻa.I ke kaʻina hana o ka tungsten, molybdenum a me ka paʻakikī paʻakikī, ʻo ka hapa nui o ka umu hoʻohaʻahaʻa a me ka sintering furnace e ka molybdenum wire heating, ʻo kēia ʻano umu e hōʻemi ana i ka lewa a i ʻole ka lewa non-oxidizing.Hiki ke hoʻohana ʻia ka uea Molybdenum i kahi kokoke i ka helu heheʻe i ka hydrogen a me ka amonia decomposition, a hiki ke hoʻohana ʻia i 2000 ℃ i ka nitrogen.Hoʻohana ʻia ʻo Molybdenum e like me ke aniani hoʻoheheʻe ʻana i nā mea hoʻoheheʻe wela kiʻekiʻe, e like me ke alakaʻi pahu, paipu, crucible, runner a me nā koʻokoʻo hoʻoheheʻe honua.ʻO ka hoʻohana ʻana i ka molybdenum ma kahi o ka platinum i loko o ka umu ahi kiʻi fiberglass he hopena maikaʻi a hoʻemi nui i ke kumukūʻai hana.
Ka ʻaila ʻaila
I ka hoʻomohala ʻana i ke kinoea kūlohelohe a me nā māla aila ma nā wahi haʻahaʻa a me nā māla aila a me ke kinoea, ʻaʻole wale ka nui o ke kinoea H2S i hana ʻia, akā ʻo ka hoʻoheheʻe ʻia ʻana o ka wai kai, kahi e hoʻoheheʻe ʻia ai ka pipeline drilling brittle a corroded wikiwiki.Hiki i ke kiʻekiʻe kiʻekiʻe ke kila kila kila i loko o ka molybdenum hiki ke pale pono i ka ʻino o ke kinoea H2S a me ka wai kai, mālama nui i ke kila a hōʻemi i ke kumukūʻai wili o ka ʻaila a me ke kinoea Wells.ʻAʻole hiki ke hoʻohana wale ʻia ka Molybdenum i ka pipeline wili ʻana i ka aila a me ke kinoea, akā ua hui pū ʻia me ka cobalt a me ka nickel ma ke ʻano he catalyst no ka hoʻomaʻemaʻe ʻana i ka ʻaila, hoʻohana nui ʻia no ka desulfurization o ka ʻaila, nā huahana petrochemical a me nā lanahu liquefied.
Nā ʻoihana mokulele a me nā ʻoihana nuklea
Ma muli o kona kūpaʻa wela maikaʻi a me nā waiwai mechanical kiʻekiʻe, hiki ke hoʻohana ʻia ka molybdenum alloy e like me ke alakaʻi ahi a me ke keʻena kuni o nā ʻenekini mokulele, ka ʻāʻī, nozzle a me ka valve o nā ʻenekini rocket wai o nā spacesuits, ka hopena o ka lele hou ʻana, ka ʻili. o nā ukali a me nā mokulele, ka ʻēheu moku a me ka pepa alakaʻi a me nā mea uhi pale.Hiki i ka antenna satellite i hana ʻia me ka molybdenum mesh ke mālama i kahi ʻano parabolic piha, ʻoiai ʻoi aku ka māmā ma mua o nā antenna composite graphite.Hoʻohana ka missile cruise-type i nā mea i uhi ʻia i ka molybdenum e like me ka turbo-rotor.Hana ia ma 1300 ℃ me ka wikiwiki a hiki i 40 -- 60 tausani hoʻololi i kēlā me kēia minuke, i hōʻike i nā hopena maikaʻi.
Nā huahana kemika Molybdenum
Molybdenum a me chromium, alumini paʻakai hiki ke co-deposited e hana molybdate ulaula puaʻa, molybdate ions a me ka metala ili hao ion e hana insoluble Fe2(MoO4)3, no laila, i ka metala ili passivation, rust ka hopena.Hoʻololi kona waihoʻoluʻu mai ka ʻalani māmā a hiki i ka ʻulaʻula māmā, me ka hiki ke uhi ikaika, a me ka waihoʻoluʻu ʻālohilohi, hoʻohana nui ʻia i nā uhi, plastics, rubber, inika, automotive a me Marine coatings a me nā māla ʻē aʻe.ʻO ka Molybdenum disulfide (MoS2) he lubricant paʻa maikaʻi, kahi mea nui loa i nā noi ʻoihana.He haʻahaʻa haʻahaʻa loa ia o ka friction (0.03 -- 0.06), ka ikaika hua kiʻekiʻe (3.45MPa), hiki ke hoʻohana ʻia i ka wela kiʻekiʻe (350 ℃) a me nā ʻano wela haʻahaʻa haʻahaʻa loa, i nā kūlana vacuum hiki ke hana ma 1200 ℃ maʻamau, ʻoi aku ka nui o ka holo wikiwiki ʻana o nā ʻāpana mechanical he lubrication maikaʻi loa.No laila, hoʻohana nui ʻia ia i nā turbines mahu, nā turbines kinoea, nā wili metala, nā niho niho, nā mold, nā kaʻa a me nā mea hana aerospace.
Mea hoʻomomona mahiʻai
I nā makahiki i hala iho nei, ua hoʻohana nui ʻia ka ammonium molybdate ma ke ʻano he trace element fertilizer ma ka home a ma waho, hiki ke hoʻomaikaʻi nui i ka maikaʻi a me ka hua o nā mea kanu legume, nā mea kanu a me nā mea kanu ʻē aʻe.Hiki i ka Molybdenum ke hoʻoikaika i ka absorption o ka phosphorus i nā mea kanu a pāʻani i kāna kuleana i nā mea kanu, akā e wikiwiki hoʻi i ka hoʻokumu ʻana a me ka hoʻololi ʻana o nā carbohydrates i nā mea kanu, hoʻomaikaʻi i ka ʻike a me ka paʻa o ka chlorophyll mea kanu, a hoʻomaikaʻi i ka ʻike o ka huaora C. Eia kekahi, hiki i ka molybdenum ke hoʻomaikaʻi i ka maloʻo a me ke kū anuanu a me ka pale ʻana i nā maʻi o nā mea kanu.
