ʻO ka noi Molybdenum a me ka hoʻomeheu ʻepekema

ʻO Molybdenum kahi mea hao, hōʻailona hōʻailona: Mo, inoa Pelekania: molybdenum, helu ʻĀtoma 42, he metala VIB. ʻO 10.2 g / cm 3 ka mānoanoa o ka molybdenum, ʻo ka helu hoʻoheheʻe ʻo 2610 ℃ a ʻo ka paila paila he 5560 ℃. ʻO Molybdenum kahi ʻano o ke kila keʻokeʻo silvery, paʻakikī a paʻakikī, me kahi pae hoʻoheheʻe kiʻekiʻe a me ka conductivity wela kiʻekiʻe. ʻAʻole ia e pane me ka ea i ka mahana o ka lumi. Ma ke ʻano he mea hoʻololi, maʻalahi e hoʻololi i kona mokuʻāina, a e loli ke kala o ka molybdenum ion me ka loli o ka mokuʻāina. ʻO Molybdenum kahi mea pono no ke kino o ke kanaka, nā holoholona a me nā mea kanu, kahi mea nui i ka ulu ʻana, ulu a me nā hoʻoilina o nā kānaka, nā holoholona a me nā mea kanu. ʻO ka awelika o ka molybdenum i ka pahu honua ka 0,00011%. ʻO nā mālama waiwai molybdenum honua ma kahi o 11 miliona mau tona, a ʻo nā waihona i hōʻoia ʻia ma kahi o 19.4 miliona mau tona. Ma muli o kona ikaika kiʻekiʻe, wahi hoʻoheheʻe kiʻekiʻe, kūpaʻa kūpale a ʻaukake ʻaukake, hoʻohana nui ʻia ka molybdenum i ke kila, ʻaila ʻaila, ʻenekini, ʻenehana uila a me ka uila. 3 mea hoʻoheheʻe keleawe: noi o molybdenum

Noho ʻo Molybdenum i ka wahi mua ma ka ʻoihana hao a me ka hao, e helu ana ma kahi o 80% o ka nui o ka ʻai ʻana o molybdenum, ukali ʻia e ka ʻoihana kemika, e helu ana ma kahi o 10%. Hoʻohui ʻia, hoʻohana ʻia ka molybdenum i ka ʻenehana uila a me ka uila, ka lāʻau lapaʻau a me ka mahiʻai, e helu ana ma kahi o 10% o ka nui o ka ʻai.

ʻO Molybdenum ka mea kūʻai nui o ka hao a me ke kila, a hoʻohana nui ʻia i ka hana o ke kila kila (ma kahi o 43% o ka molybdenum i ka nui o ka hoʻohana kila), mea kila kila (ma kahi o 23%), mea kila kila a me ke kila kiʻekiʻe (ma kahi o 8% ), hoʻolei hao a me ka wili (ma kahi o 6%). Hoʻohana pololei ʻia ka hapa nui o ka molybdenum i ka hana kila a i ʻole ka hao hao ma hope o ka hana ʻana o ka molybdenum oxide briquetting, ʻoiai e hoʻoheheʻe ʻia kahi ʻāpana liʻiliʻi i ferromolybdenum a laila hoʻohana ʻia no ka hana kila. Ma ke ʻano he mea hao o ka kila, he mea maikaʻi aʻe ko ka molibdenum: hoʻomaikaʻi i ka ikaika a me ka paʻakikī o ke kila; ke hoʻomaikaʻi nei i ka pale kūpaʻa o ke kila i ka hopena acid-base a me ka mea hao wai; ke hoʻomaikaʻi nei i ka pale pale o ke kila; hoʻomaikaʻi i ka hardenability, weldability a me ka wela ia'ku o ka kila. ʻO kahi laʻana, hoʻohana kila kila me ka molybdenum ʻike o 4% - 5% hoʻohana pinepine ʻia i nā wahi me ka popopo koʻikoʻi a me ka popopo, e like me nā lako kai a me nā pono kemika.

Hoʻokomo ʻia ke kinikini non-ferrous o ka molybdenum matrix a me nā mea ʻē aʻe (e like me Ti, Zr, HF, W a me re). ʻAʻole pili wale kēia mau mea hana i ka hoʻonā hoʻoikaika a me ka hoʻohaʻahaʻa haʻahaʻa o ka molybdenum alloy, akā hana pū kekahi hoʻi i kahi papa carbide paʻa, hiki ke hoʻomaikaʻi i ka ikaika a me ka mahana hou o ke aniani. Hoʻohana ākea ka molibdenum i hoʻokumu ʻia i nā mea hoʻoheheʻe kiʻekiʻe, nā abrasives extrusion, nā aniani uila hoʻoheheʻe kī, ka uhi ʻehu, nā mea hana hana metala, nā ʻāpana mokulele a pēlā aku ma muli o ko lākou ikaika maikaʻi, paʻa paʻa mechanical a me ductility kiʻekiʻe.

2. Hoʻonohonoho nui ʻia nā kumuwaiwai molibdenum i ka honua ma ka lihi hikina o ka Basin Pacific, ʻo ia, mai Alaska a me British Columbia ma o ʻAmelike Hui Pū ʻIa a me Mexico a hiki i Andes, Chile. ʻO ka mauna mauna kaulana ʻo nā mauna ʻo Cordillera ma ʻAmelika. Nui nā waihona porphyry molybdenum a me nā waihona keleawe porphyry i loko o nā kuahiwi, e like me clemesk a me Henderson porphyry molybdenum deposit i ʻAmelika Hui Pū ʻIa, elteniente a me chuki ma Chile ʻO nā waihona molybdenum keleawe porphyry ma Kamata, El Salvador a me pispidaka ma Kanada, andako porphyry molybdenum deposit in Canada and hailanwali porphyry copper molybdenum deposit in Canada, etc. Ua waiwai pū ʻo Kina i nā kumuwaiwai molybdenum, me nā mokuʻāina ʻo Henan, Shaanxi a me Jilin e helu ana he 56.5% o ka huina nui o nā waiwai molybdenum ma Kina.

ʻO Kina kekahi o nā ʻāina me nā kumu waiwai molybdenum nui loa i ka honua. Wahi a ka ʻikepili i hoʻokuʻu ʻia e ke Kuhina o ka ʻāina a me nā kumuwaiwai, i ka hopena o 2013, ua mālama ʻia nā waihona Molybdenum o Kina he 26,202 miliona mau tona (mea hao). I ka makahiki 2014, ua hoʻonui ʻia nā waihona Molybdenum Kina e 1.066 miliona mau tona (metala), no laila ma 2014, ua hiki aku nā waihona Molybdenum o Kina i 27.268 miliona mau tona (metala ʻike kila). Hoʻohui ʻia, mai ka makahiki 2011, ua ʻike ʻo Kina i ʻekolu mau mines molybdenum me ka hiki ke loaʻa he 2 miliona mau tona, e like me ka forminggou i ka moku ʻo Anhui. Ma ke ʻano he ʻāina nui o nā waiwai molybdenum i ka honua, paʻa paʻa ka waihona kumuwaiwai o Kina.
