Molybdenum kev thov thiab kev kawm nrov

Molybdenum yog hlau tsim, lub cim keeb kwm: Mo, Lus Askiv Lub Npe: molybdenum, atomic number 42, yog VIB hlau. Qhov ntom ntom nti ntawm molybdenum yog 10.2 g / cm 3, lub ntsiab lus yaj yog 2610 ℃ thiab qhov kub taw yog 5560 ℃. Molybdenum yog hom ntawm silvery dawb hlau, tawv thiab tawv, nrog lub siab yaj thiab siab thermal conductivity. Nws tsis cuam tshuam nrog cua ntawm chav sov. Raws li kev hloov pauv, nws yooj yim los hloov nws lub xeev oxidation, thiab cov xim ntawm molybdenum ion yuav hloov nrog kev hloov pauv ntawm lub xeev oxidation. Molybdenum yog cov keeb kwm tseem ceeb rau tib neeg lub cev, tsiaj thiab nroj tsuag, uas yog lub luag haujlwm tseem ceeb hauv kev loj hlob, kev loj hlob thiab qub txeeg qub teg ntawm tib neeg, tsiaj thiab nroj tsuag. Qhov nruab nrab cov ntsiab lus ntawm molybdenum hauv ntiaj teb ua kaub puab yog 0.00011%. Lub ntiaj teb molybdenum cov peev txheej ceev yog 11 lab tons, thiab cov khoom pov thawj muaj kwv yees li 19.4 lab tons. Vim tias nws lub zog loj, siab melting point, corrosion tsis kam thiab hnav tsis kam, molybdenum yog siv dav hauv cov hlau, roj av, tshuaj, hluav taws xob thiab hluav taws xob tshuab, tshuaj thiab kev ua liaj ua teb. 3 refractory hlau: daim ntawv thov ntawm molybdenum

Molybdenum nyob hauv thawj qhov chaw hauv kev lag luam hlau thiab hlau, suav txog 80% ntawm tag nrho kev noj ntawm molybdenum, tom qab ntawd kev lag luam chemical, suav txog kwv yees li 10%. Tsis tas li ntawd, molybdenum tseem tseem siv hauv hluav taws xob thiab hluav taws xob thev naus laus zis, tshuaj thiab kev ua liaj ua teb, suav txog kwv yees li 10% ntawm tag nrho kev noj.

Molybdenum yog cov neeg siv khoom loj tshaj plaws ntawm cov hlau thiab cov hlau, thiab yog siv rau hauv cov khoom ntawm cov hlau tsis sib luag (li 43% ntawm molybdenum nyob rau hauv tag nrho cov kev siv hlau), stainless hlau (kwv yees li 23%), cov cuab yeej siv hlau thiab cov hlau siab (li 8% ), cam khwb cia hlau thiab hlau (li 6%). Feem ntau ntawm molybdenum siv ncaj qha rau hauv kev tsim cov hlau los yog cov hlau nrum tom qab kev lag luam molybdenum oxide briquetting, thaum ib feem me me yog melted rau hauv ferromolybdenum thiab tom qab ntawd siv rau kev tsim steel. Raws li cov ntsiab lus sib xyaw ntawm cov hlau, molybdenum muaj qhov zoo li nram no: txhim kho lub zog thiab tawv ntawm cov hlau; txhim kho qhov kev txhim kho corrosion ntawm steel hauv acid-puag daws thiab kua hlau; txhim kho qhov hnav tsis kam ntawm cov hlau; txhim kho lub hardenability, weldability thiab kub tsis kam ntawm cov hlau. Piv txwv li, cov hlau tsis xeb nrog molybdenum cov ntsiab lus ntawm 4% - 5% feem ntau siv rau hauv qhov chaw nrog kev xeb thiab kev xeb, xws li cov khoom siv marine thiab cov cuab yeej siv tshuaj.

Lub non-ferrous alloy yog tsim ntawm molybdenum matrix thiab lwm yam khoom siv (xws li Ti, Zr, HF, W thiab re). Cov ntsiab lus tsis zoo tsuas yog ua lub luag haujlwm hauv kev daws teeb meem thiab qhov kub thiab txias ntawm cov khoom ntawm molybdenum alloy, tab sis kuj tseem tsim cov qib ruaj khov thiab tawg carbide, uas tuaj yeem txhim kho lub zog thiab recrystallization kub ntawm lub alloy. Molybdenum based alloys yog siv dav hauv cov cua kub siab, extrusion abrasives, iav melting rauv hluav taws xob, txau txheej, hlau ua cov cuab yeej, qhov chaw hauv av thiab lwm yam vim tias lawv lub zog zoo, muaj kev ruaj khov thiab siab ductility.

2. Cov khoom siv hauv Molybdenum hauv ntiaj teb no yog qhov tseem ceeb nyob rau sab hnub tuaj ntawm ntug hiav txwv Pacific, uas yog, los ntawm Alaska thiab British Columbia hla Tebchaws Asmeskas thiab Mexico mus rau Andes, Chile. Lub roob muaj zog tshaj plaws yog lub roob Cordillera hauv Asmeskas. Muaj ntau ntawm porphyry molybdenum tso nyiaj thiab porphyry tooj liab tso nyiaj nyob rau hauv cov roob, xws li clemesk thiab Henderson porphyry molybdenum tso nyiaj hauv Tebchaws Meskas, elteniente thiab chuki hauv Chile Lub porphyry tooj liab molybdenum tso nyiaj hauv Kamata, El Salvador thiab pispidaka hauv Canada, andako porphyry molybdenum tso nyiaj hauv Canada thiab hailanwali porphyry tooj liab molybdenum tso nyiaj hauv Canada, thiab lwm yam. Tuam Tshoj tseem nplua nuj molybdenum cov khoom siv, nrog Henan, Shaanxi thiab Jilin cov xeev tso nyiaj rau 56.5% ntawm tag nrho cov nyiaj ntawm molybdenum cov khoom siv hauv Suav.

Tuam Tshoj yog ib lub teb chaws uas muaj kev nplua nuj molybdenum ntau tshaj plaws nyob hauv lub ntiaj teb. Raws li cov ntaub ntawv tso tawm los ntawm Ministry of land thiab cov peev txheej, thaum kawg ntawm xyoo 2013, Tuam Tshoj Molybdenum cia yog 26.202 lab tons (cov ntsiab lus hlau). Nyob rau xyoo 2014, Tuam Tshoj cov Molybdenum tseg tau nce li 1,066 lab tons (cov ntsiab lus hlau), yog li xyoo 2014, Tuam Tshoj Molybdenum cia tau 27.268 lab tons (cov ntsiab lus hlau). Tsis tas li ntawd, txij li xyoo 2011, Suav teb tau tshawb pom peb lub molybdenum mines nrog lub peev xwm ntawm 2 lab tons, suav nrog shapinggou hauv Anhui Xeev. Raws li lub teb chaws loj ntawm molybdenum cov khoom siv hauv lub ntiaj teb, Tuam Tshoj cov khoom siv hauv paus yog qhov ruaj khov.
