Kugwiritsa ntchito kwa Molybdenum ndi kufalitsa kwa sayansi

Molybdenum ndichinthu chachitsulo, chizindikiro chazinthu: Mo, Dzina la Chingerezi: molybdenum, nambala ya atomiki 42, ndichitsulo cha VIB. Kuchuluka kwa molybdenum ndi 10.2 g / cm 3, malo osungunuka ndi 2610 ℃ ndipo malo otentha ndi 5560 ℃. Molybdenum ndi mtundu wa chitsulo choyera, cholimba komanso cholimba, chokhala ndi malo osungunuka kwambiri komanso otentha kwambiri. Sichikugwira ntchito ndi mpweya kutentha. Monga chinthu chosinthira, ndikosavuta kusintha mkhalidwe wake wa makutidwe ndi okosijeni, ndipo mtundu wa molybdenum ion umasintha ndi kusintha kwa dziko la makutidwe ndi okosijeni. Molybdenum ndichinthu chofunikira kwambiri m'thupi la munthu, nyama ndi zomera, chomwe chimagwira gawo lofunikira pakukula, chitukuko ndi cholowa cha anthu, nyama ndi zomera. Zomwe zili molybdenum mu kutumphuka kwa dziko lapansi ndi 0.00011%. Zosungidwa padziko lonse lapansi za molybdenum zili pafupifupi matani 11 miliyoni, ndipo nkhokwe zotsimikiziridwa zili pafupifupi matani 19.4 miliyoni. Chifukwa cha mphamvu yake yayikulu, malo osungunuka kwambiri, kukana dzimbiri komanso kuvala, molybdenum imagwiritsidwa ntchito kwambiri pazitsulo, mafuta, mafuta, zamagetsi ndi zamagetsi, zamankhwala ndi ulimi. 3 chitsulo chosanja: kugwiritsa ntchito molybdenum

Molybdenum ndiye malo oyamba pazitsulo ndi zitsulo, zowerengera pafupifupi 80% yazakumwa chonse cha molybdenum, chotsatiridwa ndi makampani azamagetsi, omwe amawerengera pafupifupi 10%. Kuphatikiza apo, molybdenum imagwiritsidwanso ntchito pamagetsi amagetsi ndi zamagetsi, zamankhwala ndi zaulimi, kuwerengera pafupifupi 10% yazogwiritsidwa ntchito zonse.

Molybdenum ndiye wogula kwambiri wazitsulo ndi chitsulo, ndipo amagwiritsidwa ntchito kwambiri pakupanga chitsulo cha aloyi (pafupifupi 43% ya molybdenum yogwiritsira ntchito chitsulo chonse), chitsulo chosapanga dzimbiri (pafupifupi 23%), chitsulo chachitsulo ndi chitsulo chothamanga (pafupifupi 8% ), Ndikutaya chitsulo ndi wodzigudubuza (pafupifupi 6%). Ambiri mwa molybdenum amagwiritsidwa ntchito mwachindunji pakupanga chitsulo kapena chitsulo atapanga mafakitale a molybdenum oxide briquetting, pomwe gawo laling'ono limasungunuka kukhala ferromolybdenum kenako limagwiritsidwa ntchito popanga chitsulo. Monga chitsulo chosungunuka chachitsulo, molybdenum ili ndi zabwino izi: kukonza mphamvu ndi kulimba kwazitsulo; kukonza kukana dzimbiri zitsulo mu njira asidi-m'munsi ndi chitsulo madzi; kukonza kukana kwazitsulo; kukonza hardenability, weldability ndi kutentha kukana chitsulo. Mwachitsanzo, chitsulo chosapanga dzimbiri chokhala ndi molybdenum cha 4% - 5% chimakonda kugwiritsidwa ntchito m'malo okhala ndi dzimbiri komanso dzimbiri, monga zida zam'madzi ndi zida zamagetsi.

Chitsulo chosakhala chachitsulo chimapangidwa ndi molybdenum matrix ndi zinthu zina (monga Ti, Zr, HF, W ndi re). Zinthu izi za aloyi zimangothandiza pakuthandizira kuthana ndi kutentha kwaposachedwa kwa aloyi ya molybdenum, komanso zimapanga gawo lolimba komanso lobalalika la carbide, lomwe lingalimbikitse kutentha ndi kuyambiranso kutentha kwa aloyi. Ma alloys a Molybdenum amagwiritsidwa ntchito kwambiri pamatenthedwe otentha, zotsekemera za extrusion, magalasi osungunulira magalasi amoto, zokutira utsi, zida zopangira zitsulo, zida zamlengalenga ndi zina zotero chifukwa champhamvu zawo, kukhazikika kwamakina komanso ductility yayikulu.

2. Chuma cha Molybdenum padziko lapansi chimapezeka makamaka kum'mawa kwa Pacific Basin, ndiko kuti, kuchokera ku Alaska ndi British Columbia kudzera ku United States ndi Mexico mpaka ku Andes, Chile. Mapiri otchuka kwambiri ndi mapiri a Cordillera ku America. Pali mitundu yambiri yamapiri a porphyry molybdenum ndi porphyry zamkuwa m'mapiri, monga clemesk ndi Henderson porphyry molybdenum madipoziti ku United States, elteniente ndi chuki ku Chile Malo a porphyry copper molybdenum amasungidwa ku Kamata, El Salvador ndi pispidaka ku Canada, andako porphyry molybdenum deposit ku Canada ndi hailanwali porphyry mkuwa wa molybdenum deposit ku Canada, ndi zina zotero.China ili ndi chuma chambiri molybdenum, zigawo za Henan, Shaanxi ndi Jilin zimawerengera 56.5% yazinthu zonse za molybdenum ku China.

China ndi amodzi mwa mayiko omwe ali ndi chuma chambiri cha molybdenum padziko lapansi. Malinga ndi zomwe idatulutsidwa ndi Unduna wa Zachuma ndi zothandizira, kumapeto kwa 2013, malo osungidwa ku China a Molybdenum anali matani 26.202 miliyoni (zazitsulo). Mu 2014, nkhokwe zaku China za Molybdenum zidakwera ndi matani 1.066 miliyoni (zitsulo), kotero pofika 2014, nkhokwe zaku China za Molybdenum zafika matani miliyoni 27.268 (chitsulo). Kuphatikiza apo, kuyambira 2011, China idapeza migodi itatu ya molybdenum yokhala ndi matani 2 miliyoni, kuphatikiza shapinggou m'chigawo cha Anhui. Monga dziko lalikulu kwambiri lazinthu za molybdenum padziko lapansi, zida zaku China ndizokhazikika.
