Vim li cas thiaj ua taumolybdenum hlautxiav hlau?
Ntau tus neeg tau hnov txog cov hlau txiav, thiab molybdenum hlau txiav kuj yog hom hlau txiav. Yog li vim li cas molybdenum hlau txiav hlau? Ntau tus neeg yuav xav tias molybdenum hlau txiav yog txiav hlau nrog molybdenum hlau, ib yam li txiav ntoo nrog saw. Qhov tseeb, qhov no tsis yog qhov xwm txheej. Yog li hauv tsab xov xwm no, peb yuav sim nrhiav seb vim li cas molybdenum hlau tuaj yeem txiav hlau. Tab sis ua ntej, cia peb nkag siab tias molybdenum thiab molybdenum hlau yog dab tsi.
Dab tsi yog molybdenum thiab molybdenum hlau?
Molybdenum yog cov nyiaj-dawb refractory hlau. Nyob rau hauv tsos, cov hlau molybdenum zoo ib yam li tungsten, tab sis nws tseem yog ib qho yooj yim kom paub qhov txawv ntawm qhov ceev. Molybdenum tsuas yog ib nrab tuab li tungsten.
Molybdenum yog cov hlau tsis tshua muaj nyob hauv lub ntiaj teb, cuam tshuam nrog peb lub neej thiab siv dav. Piv txwv li, molybdenum yog cov hlau zoo siv hauv kev lag luam tiv thaiv, ib qho tseem ceeb ntawm cov hlau alloys, thiab cov khoom noj tseem ceeb uas yuav tsum tau muaj los ntawm cov nroj tsuag thiab tsiaj txhu. Vim nws muaj zog heev interatomic bonding quab yuam, nws muaj lub zog siab ntawm chav tsev kub thiab kub.
Molybdenum hlau yog cov hlau hlau uas muaj txoj kab uas hla ntawm {{0}}.02 hli thiab 0.2 hli ua los ntawm molybdenum ua cov khoom tseem ceeb (ntau tshaj 99%). Nws muaj kev ntxhib los mos thiab lub zog tensile siab thiab yog siv los txiav workpieces hauv kev lag luam. Molybdenum hlau muaj qhov ua tau zoo, tsis tshua muaj hlau tawg tus nqi thiab kev ua haujlwm ceev ceev, uas tuaj yeem ua tiav kev ruaj khov thiab ua haujlwm ntev. Molybdenum hlau tuaj yeem tsis tsuas yog txheej txheem ntau yam hlau, tab sis kuj yog siv dav hauv cov hlau lead, cua sov, thiab lwm yam.
Yuav ua li cas molybdenum hlau txiav ua haujlwm
Txawm hais tias molybdenum hlau muaj ntau yam zoo heev, nws tsis hnav-tiv taus thiab yog li tsis tuaj yeem siv los txiav hlau zoo li lub saw. Lub hauv paus ntsiab lus ntawm molybdenum hlau txiav yog ua kom lub zog ntawm molybdenum xaim thiab tso tawm cov khoom ua haujlwm, ua kom muaj qhov kub thiab txias ntawm ntau txhiab degrees, ua rau cov khoom tawm ntawm lub workpiece kom yaj lossis vaporize, yog li ua tiav kev txiav.
Thaum txiav lub workpiece, cov hlau molybdenum kuj yuav tsum tau muab tso rau hauv cov kua insulating. Thiab qhov tso tawm thaum lub sij hawm txiav yog pulse tawm. Nyob rau hauv qhov kev txiav txim ntawm pulse voltage, lub insulating kua yog tawg, tsim ib qho instant paug channel ntawm molybdenum hlau thiab lub workpiece. Thaum lub sij hawm lub sij hawm mem tes, cov kua insulating puv lub tso tawm channel dua, thiab lwm yam. Tsis tas li ntawd, cov kua insulating kuj muaj cov haujlwm ntawm kev tshem tawm cov khoom siv hluav taws xob hauv qhov sib txawv thiab ua kom txias cov electrodes.
