Dab tsi yog 5 hom kev siv molybdenum?
Dab tsi yogmolybdenumsiv rau?
Nyob rau hauv 1782, Elm ntawm Sweden siv ib tug sib tov ntawm charcoal thiab molybdic acid tov nrog linseed roj los ua kaw combustion kom tau molybdenum. Molybdenum yog cov hlau dawb-dawb. Nws yog ib qho nyuaj thiab tawv thiab tsis corroded los ntawm huab cua ntawm chav tsev kub. Tsis muaj tshuaj lom nrog hydrochloric acid lossis hydrofluoric acid. Molybdenum feem ntau yog siv hauv kev lag luam steel (80%), ua raws li cov ntawv thov hauv kev lag luam tshuaj, suav txog kwv yees li 10%. Tsis tas li ntawd, molybdenum kuj tseem siv rau hauv cov khoom siv hluav taws xob thiab hluav taws xob, tshuaj, kev ua liaj ua teb thiab lwm yam.
Kev siv ntawm molybdenum hauv steel teb:
Nyob rau hauv lub steel teb, molybdenum yog tsuas yog siv nyob rau hauv zus tau tej cov hlau alloy, stainless hlau, cuab yeej steel, high-speed steel, cam khwb cia hlau, yob, thiab lwm yam. hnav tsis kam ntawm steel, thiab txhim kho hardenability, weldability, thiab kub tsis kam ntawm steel. Molybdenum alloys tsim los ntawm kev ntxiv lwm cov ntsiab lus rau molybdenum, xws li molybdenum-lanthanum alloys thiab TZM alloys, muaj cov khoom zoo dua li cov ntshiab molybdenum.
Kev siv ntawm molybdenum hauv chemistry:
Hauv kev lag luam tshuaj, molybdenum yog siv los ua cov roj nplua nyeem, catalyst, pigment, nplaim hluav taws kub hnyiab thiab cov pa luam yeeb, thiab ua cov tshuaj tiv thaiv corrosion rau cov organic polymers. Cov khoom tseem ceeb yog molybdenum dioxide, molybdenum daj, molybdate, thiab ammonium paramolybdate.
Kev siv ntawm molybdenum hauv hluav taws xob thiab hluav taws xob:
Molybdenum muaj hluav taws xob zoo conductivity thiab kub ua hauj. Nws thermal expansion coefficient zoo ib yam li iav. Nws yog dav siv nyob rau hauv zus tau tej cov tub ntxhais xov hlau, leads, hooks thiab lwm yam khoom ntawm kauv filaments. Molybdenum hlau kuj yog ib qho zoo tagnrho electrode hlau rau txiav cov cuab yeej tshuab thiab tuaj yeem txiav ntau yam hlau thiab carbide. Nws cov txheej txheem yog ruaj khov thiab tuaj yeem txhim kho qhov tseeb ntawm cov pwm.
Kev siv molybdenum hauv kev kho mob, tsiaj txhu, thiab kev ua liaj ua teb:
Molybdenum yog ib qho ntawm cov kab tseem ceeb rau tib neeg lub cev. Qhov tsim nyog ntawm molybdenum tuaj yeem txhawb kev loj hlob ntawm tib neeg lub cev, txhim kho oxygen cia hauv lub cev, thiab inhibit qog.
Ammonium molybdate yog siv los ua cov khoom muaj nyob hauv cov tshuaj. Hauv cov tsiaj, molybdenum yog ib feem ntawm molybdenum enzyme. Ntxiv molybdenum additives rau pub tuaj yeem ua tau raws li qhov xav tau ntawm cov tsiaj. Molybdenum kuj yog ib qho ntawm cov kab uas tsim nyog rau kev loj hlob ntawm cov nroj tsuag. Kev siv molybdenum ammonium rau sowing noob tuaj yeem ua rau kom cov paj ntau ntau.
