Molybdenum kunyorera uye sainzi kukurumbira

Molybdenum chinhu chesimbi, chiratidzo chechinhu: Mo, Chirungu Zita: molybdenum, atomic nhamba makumi mana nemaviri, iVIB simbi. Kuwedzera kweiyo molybdenum ndeye 10.2 g / cm 3, iyo yekunyungudika ndeye 2610 ℃ uye iyo yekubikira nzvimbo iri 5560 ℃. Molybdenum rudzi rwesirivha chena simbi, yakaoma uye yakaoma, ine yakanyanya kusungunuka poindi uye yakanyanya kupisa kupisa. Izvo hazviite nemhepo pane tembiricha yemukati. Sechinhu cheshanduko, zviri nyore kushandura mamiriro ayo eiyo oxidation, uye ruvara rwe molybdenum ion ruchachinja pamwe nekushanduka kweiyo oxidation yenyika. Molybdenum yakakosha yekuteedzera chinhu chemuviri wemunhu, mhuka uye zvirimwa, izvo zvinoita basa rakakosha mukukura, kusimudzira uye nhaka yevanhu, mhuka uye zvirimwa. Ivhareji yezvinyorwa zvemolybdenum muvhu yepasi ndeye 0.00011%. Iyo yepasi rose molybdenum zviwanikwa masosi ari angangoita mamirioni gumi nematatu, uye matura anoratidzwa ari angangoita mamirioni 19.4 ematani. Nekuda kwesimba rayo rakakwirira, kukwirira kwakanyunguduka, kuramba ngura uye kupfeka kuramba, molybdenum inoshandiswa zvakanyanya musimbi, peturu, kemikari, magetsi uye zvemagetsi tekinoroji, mushonga uye kurima. 3 inogadziriswa simbi: kushandiswa kwemolybdenum

Molybdenum inotora nzvimbo yekutanga muindasitiri yesimbi neyesimbi, inotora chikamu chinosvika makumi masere muzana cheyese yekudyiwa kwemolybdenum, ichiteverwa nemakemikari indasitiri, inoverenga ingangoita gumi muzana. Uye zvakare, molybdenum inoshandiswawo mune zvemagetsi uye zvemagetsi tekinoroji, mushonga uye kurima, kuverenga nezve ingangoita 10% yehuwandu hwekushandisa.

Molybdenum ndiyo mutengi mukuru wesimbi nesimbi, uye inonyanya kushandiswa mukugadzira simbi yesimbi (inenge 43% ye molybdenum mune yakazara simbi yekushandisa), simbi isina simbi (inenge 23%), simbi yesimbi uye nesimbi yekumhanyisa (ingangoita 8% ), Simbi yakakoswa uye roller (inenge 6%). Mazhinji emolybdenum anoshandiswa zvakananga mukugadzira simbi kana kukanda simbi mushure meindasitiri molybdenum oxide briquetting, nepo chikamu chidiki chanyungudika kuita ferromolybdenum ndokuzoshandiswa kugadzira simbi. Sechinhu chiwanikwa chesimbi, molybdenum ine zvinotevera zvakanakira: kugadzirisa simba uye kuomarara kwesimbi; kugadzirisa kurwisa kwekuora kwesimbi muacid-base solution uye mvura yesimbi; kunatsiridza kusakara kuramba kwesimbi; kugadzirisa kuomarara, weldability uye kupisa kupisa kwesimbi. Semuenzaniso, simbi isina chinhu ine molybdenum zvemukati zve4% - 5% inowanzo shandiswa munzvimbo dzine ngura yakakomba uye ngura, senge michina yegungwa uye michina yemakemikari.

Iyo isiri-ferrous alloy inoumbwa nemolybdenum matrix uye zvimwe zvinhu (senge Ti, Zr, HF, W uye re). Aya maalloy element haangobate basa mukugadzirisa kusimbisa uye pasi-tembiricha mapurasitiki emolybdenum alloy, asi zvakare inoumba yakagadzikana uye yakapararira carbide chikamu, icho chinogona kuvandudza simba uye kudzokororazve tembiricha yesimbi. Molybdenum yakavakirwa maalloys anoshandiswa zvakanyanya munzvimbo dzakakisa kudziyisa zvinhu, extrusion abrasives, girazi rinonyungudusa vira remagetsi, kuputira kupfeka, maturusi ekugadzirisa simbi, zvikamu zve spacecraft uye zvichingodaro nekuda kwesimba ravo rakanaka.

2. Molybdenum zviwanikwa zviri munyika zvinonyanya kuiswa kumabvazuva kwePacific Basin, ndiko kuti, kubva kuAlaska neBritish Columbia kuburikidza neUnited States neMexico kusvika kuAndes, Chile. Makomo anozivikanwa kwazvo makomo eCordillera muAmerica. Kune huwandu hwakawanda hwe porphyry molybdenum deposits uye porphyry mhangura inochengetwa mumakomo, senge clemesk uye Henderson porphyry molybdenum deposits muUnited States, elteniente uye chuki muChile Iyo porphyry mhangura molybdenum inoiswa muKamata, El Salvador uye pispidaka muCanada, andako porphyry molybdenum dhipoziti muCanada uye hailanwali porphyry mhangura molybdenum dhipoziti muCanada, nezvimwewo China yakapfuma mune molybdenum zviwanikwa, pamwe neHenan, Shaanxi neJilin mapurovhinzi anoverengera 56.5% yehuwandu hwehuwandu hwemolybdenum zviwanikwa kuChina.

China ndeimwe yenyika dzine yakawanda kwazvo molybdenum zviwanikwa pasi rose. Sekureva kwedhata rakaburitswa nebazi rezvevhu uye zviwanikwa, panopera gore ra2013, matura eChina eMolybdenum aive matani emamirioni 26.202 (zvemukati zvesimbi). Muna 2014, matura eChina eMolybdenum akawedzera nematoni miriyoni 1,666 (zvemukati zvesimbi), saka pakazosvika 2014, matura eChina eMolybdenum asvika matani emamirioni 27.268 (zvemukati zvesimbi). Uye zvakare, kubvira 2011, China yakawana migodhi mitatu ye molybdenum ine huwandu hwematani emamirioni maviri, kusanganisira kuumba gou muRuwa rweAnhui. Sezvo nyika hombe yemolybdenum zviwanikwa mupasi, China sosi base yakagadzikana.
