Nyob rau theem ntawm cov ntaub ntawv tshawb fawb tshiab, magnesium hlau tau dhau los ua qhov tseem ceeb ntawm kev lag luam vim nws qhov kev ua tau zoo heev thiab kev siv dav dav. Raws li lub teeb pom kev zoo hlau hauv ntiaj teb, magnesium cov khoom tshwj xeeb ua rau nws cog lus rau kev siv hauv aerospace, tsheb tsim, khoom siv hluav taws xob, biomedicine thiab lwm yam kev lag luam.
Qhov ntom ntawm magnesium hlau yog kwv yees li 1.74 g / cubic centimeter, uas tsuas yog ib nrab ntawm txhuas thiab ib feem plaub ntawm cov hlau. Cov cuab yeej zoo tshaj plaws no ua rau magnesium yog cov khoom siv zoo tshaj plaws rau cov khoom siv hnyav. Thoob plaws ntiaj teb, nrog rau kev nce ntxiv rau kev txuag hluav taws xob thiab txo qis emissions, cov cuab yeej ntawm magnesium hlau no tau txais txiaj ntsig zoo los ntawm cov tuam txhab tsheb thiab aviation.
Ntxiv rau qhov hnyav, magnesium hlau kuj tseem muaj zog txhua yam thiab rigidity. Txawm hais tias nws tsis muaj zog li txhuas thiab hlau, hauv ntau daim ntawv thov, lub zog-rau-hnyav piv ntawm magnesium yog txaus kom ua tau raws li cov qauv tsim. Tsis tas li ntawd, magnesium hlau muaj cov khoom zoo heev seismic thiab muaj peev xwm nqus tau kev co thiab suab nrov, uas tso cai rau nws muab kev caij tsheb zoo dua thaum tsim lub cev thiab cov khoom siv ntawm cov tsheb ua haujlwm siab thiab dav hlau.
Magnesium hlau kuj qhia tau zoo thermal thiab hluav taws xob conductivity, uas ua rau nws nrov tshwj xeeb hauv cov khoom siv hluav taws xob, xws li hauv cov ntaub ntawv casing rau cov khoom siv xws li laptops, mobile phones, thiab cameras. Thaum tshav kub kub dissipation zog ntawm magnesium alloy pab cov khoom siv hluav taws xob tswj qhov kub thiab txias thaum lub sijhawm ua haujlwm ntev, yog li txuas ntxiv lub neej kev pab cuam ntawm cov khoom.
Hais txog cov khoom siv tshuaj, magnesium hlau muaj tshuaj lom neeg ua haujlwm siab. Nws reacts nrog oxygen nyob rau hauv cov huab cua ntawm chav tsev kub los tsim ib tug ntom oxide zaj duab xis. Cov oxide zaj duab xis no tuaj yeem tiv thaiv cov magnesium sab hauv los ntawm kev txuas ntxiv rau cov pa oxygen, yog li muab qee qhov kev tiv thaiv corrosion. Txawm li cas los xij, vim yog cov tshuaj ua haujlwm ntawm magnesium, nws cov corrosion kuj nyob rau hauv qhov chaw ntub dej tsis zoo li cov txhuas thiab hlau. Yog li ntawd, nyob rau hauv kev siv tswv yim, kev kho deg technology feem ntau yog siv los txhim kho nws corrosion kuj.
Nws yog tsim nyog hais tias magnesium hlau kuj qhia tau hais tias muaj peev xwm loj hauv kev kho mob. Txij li thaum magnesium yog ib qho tseem ceeb ntawm cov kab mob hauv tib neeg lub cev thiab muaj biocompatibility zoo thiab biodegradability, cov kws tshawb fawb tab tom tsim cov tshuaj magnesium raws li kev cog qoob loo, xws li pob txha rau tes thiab scaffolds, uas tuaj yeem maj mam degrade, yog li txo qhov xav tau kev phais thib ob kom tshem tawm. lub implant.
Txawm li cas los xij, daim ntawv thov ntawm magnesium hlau kuj ntsib teeb meem. Lub flammability ntawm magnesium yog ib qho kev nyab xeeb uas yuav tsum tau xav txog thaum siv nws, tshwj xeeb tshaj yog nyob rau hauv tej yam kev mob xws li kub kub los yog sib tsoo, qhov twg magnesium hmoov av yuav ua rau hluav taws kub los yog tawg. Yog li ntawd, kev ntsuas kev nyab xeeb nruj yuav tsum tau ua thaum tuav thiab ua cov hlau magnesium.
Nrog rau kev txhim kho thev naus laus zis, cov txheej txheem ua haujlwm ntawm magnesium hlau kuj tseem txhim kho tas li. Piv txwv li, qhov kev tiv thaiv corrosion thiab hnav tsis kam ntawm magnesium hlau tuaj yeem txhim kho tau zoo los ntawm kev siv cov cuab yeej siv thev naus laus zis thiab kev kho deg. Nyob rau tib lub sijhawm, cov kws tshawb fawb kuj tseem ua haujlwm hnyav los tsim cov magnesium-based alloys tshiab los txhim kho lawv cov khoom tag nrho thiab nthuav dav lawv daim ntawv thov ntau yam.
Hauv luv luv, magnesium hlau tau dhau los ua lub hnub qub hauv kev tshawb fawb ntawm cov ntaub ntawv vim nws lub teeb yuag, siab zog, zoo heev thermal thiab hluav taws xob conductivity zog, nrog rau kev tiv thaiv ib puag ncig thiab biomedical muaj peev xwm nyob rau hauv tshwj xeeb teb. Nrog rau kev nruam ntej ntawm kev tsim thiab kev siv thev naus laus zis, peb muaj laj thawj ntseeg tias magnesium hlau yuav ua lub luag haujlwm tseem ceeb hauv kev siv cov khoom siv yav tom ntej.
