Molybdenum hlau feem ntau suav hais tias muaj kev nyab xeeb rau feem ntau ntawm kev lag luam thiab kev lag luam kev lag luam thaum tuav kom raug thiab kev ceev faj txog kev nyab xeeb. Txawm li cas los xij, nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias overexposure molybdenum los yog nws cov tebchaw yuav ua rau muaj kev phom sij rau kev noj qab haus huv.
Ua pa hauv molybdenum hmoov av lossis fumes, tshwj xeeb tshaj yog nyob rau hauv kev lag luam chaw, tuaj yeem ua rau muaj teeb meem ua pa. Lub sijhawm ntev raug rau qhov siab ntawm molybdenum tuaj yeem cuam tshuam rau lub raum kev ua haujlwm. Tsis tas li ntawd, qee tus neeg yuav muaj kev khaus khaus ntawm daim tawv nqaij thaum sib cuag ncaj qha nrog molybdenum los yog nws cov tebchaw.
Cov koom haum tswj hwm xws li US Occupational Safety and Health Administration (OSHA) tau tsim cov kev txwv tsis pub muaj kev cuam tshuam (PELs) rau molybdenum los tiv thaiv cov neeg ua haujlwm los ntawm kev phom sij rau kev noj qab haus huv.
Txhawm rau kom muaj kev nyab xeeb, yuav tsum tau ua raws li cov lus qhia txog kev nyab xeeb hauv chaw ua haujlwm, suav nrog kev siv cov cuab yeej tiv thaiv tus kheej, ua kom muaj cua txaus, thiab ua raws li cov kev txwv raug pom zoo. Tsis tas li ntawd, kev pov tseg kom raug thiab pov tseg cov ntaub ntawv uas muaj molybdenum yog qhov tseem ceeb los tiv thaiv ib puag ncig.
Ib yam li txhua yam khoom siv, nws yog ib qho tseem ceeb uas yuav tsum sab laj nrog cov ntaub ntawv kev nyab xeeb thiab ua raws li cov txheej txheem kev nyab xeeb tsim nyog thaum ua haujlwm nrog molybdenum lossis nws cov khoom sib xyaw. Yog tias muaj kev txhawj xeeb tshwj xeeb txog kev raug molybdenum, nws raug nquahu kom sab laj nrog tus kws tshaj lij kev noj qab haus huv thiab kev nyab xeeb lossis kws kho mob.
Molybdenum crucibles yog dav siv nyob rau hauv high kub daim ntaub ntawv, tshwj xeeb tshaj yog nyob rau hauv kev lag luam xws li metallurgy, iav manufacturing thiab khoom sintering.
Nov yog qee qhov kev siv tshwj xeeb: Smelting thiab casting: Molybdenum crucibles feem ntau yog siv los smelt thiab cam khwb cia kub kub thiab alloys xws li kub, nyiaj, thiab platinum. Molybdenum lub siab melting point thiab thermal conductivity zoo heev ua rau nws yog ib qho khoom siv zoo tshaj plaws rau kev tiv thaiv qhov kub thiab txias los ntawm cov txheej txheem hlau melting. Sintering: Molybdenum crucibles yog siv rau sintering ntawm ceramic thiab hlau hmoov, qhov kub siab yuav tsum tau ua kom tiav densification thiab grain loj hlob. Molybdenum lub inertness thiab nws muaj peev xwm tiv taus qhov kub thiab txias yam tsis muaj kev cuam tshuam nrog cov khoom ua tiav ua rau nws yog qhov tsim nyog rau kev siv sintering. Kev tsim iav: Molybdenum crucibles yog siv los tsim cov iav tshwj xeeb thiab iav ceramics. Molybdenum lub siab thermal stability thiab inertness xyuas kom meej tias nws tsis paug cov khoom raug yaj, ua rau nws yog ib qho tseem ceeb ntawm cov txheej txheem iav. Kev tsim khoom semiconductor: Hauv kev lag luam semiconductor, molybdenum crucibles yog siv rau kev loj hlob thiab kev ua cov crystals ib leeg, xws li silicon thiab lwm yam khoom siv semiconductor. High purity thiab tsis kam rau tshuaj reactivity ua molybdenum zoo tagnrho rau cov ntawv thov no.
Zuag qhia tag nrho, molybdenum crucibles muaj nuj nqis rau lawv cov kub tsis kam, tshuaj inertness, thiab durability, uas ua rau lawv tseem ceeb heev nyob rau hauv ib tug ntau yam ntawm industrial thiab scientific txheej txheem uas tsis tshua muaj kub thiab reactive ntaub ntawv.
