Hauv ntiaj teb kev tsim khoom thiab kev tsim kho, lo lus "gland metal" muaj lub ntsiab lus tseem ceeb. Nws sawv cev rau ib chav kawm ntawm cov ntaub ntawv uas muaj lub zog tshwj xeeb, ruaj khov thiab raug, ua rau lawv tsis tseem ceeb hauv ntau yam kev siv. Txij li cov khoom siv aerospace mus rau cov khoom siv kho mob, adenometals ua lub luag haujlwm tseem ceeb hauv kev tsim lub ntiaj teb niaj hnub no.
Lub ntsiab lus tseem ceeb ntawm cov hlau gland yog nws cov khoom siv kho tshuab zoo heev. Nws muaj lub zog tensile siab thiab muaj peev xwm tiv taus cov khoom hnyav thiab cov xwm txheej hnyav yam tsis muaj kev hloov pauv lossis kev ua tsis tiav. Lub zog no ua rau cov hlau sealing zoo tagnrho rau cov khoom tseem ceeb ua haujlwm hauv cov chaw ib puag ncig hnyav, xws li lub cav dav hlau, cov tshuab kev lag luam thiab cov qauv offshore.
Tsis tas li ntawd xwb,cov hlau qogyog lub npe nrov rau nws qhov kev ua tau zoo tshaj plaws thiab kev ruaj khov ntawm qhov ntev. Cov chaw tsim khoom siv cov khoom siv no los tsim cov khoom sib xyaw thiab cov khoom sib dhos nrog kev kam rau siab, ua kom muaj kev sib dhos zoo thiab kev ua tau zoo tshaj plaws. Txawm hais tias nws yog lub kaw lus iav nyuaj lossis cov cuab yeej phais mob, cov hlau gland tuaj yeem tsim cov qauv tsim uas ua tau raws li qhov xav tau tshaj plaws.
Ib qho ntawm cov yam tseem ceeb uas ua rau cov hlau gland muaj cov yam ntxwv zoo heev yog nws cov khoom sib xyaw. Feem ntau, cov hlau gland muaj cov hlau sib xyaw ua ke muaj zog xws li hlau tsis xeb, titanium, lossis nickel-based superalloys. Cov hlau sib xyaw no raug xaiv ua tib zoo rau kev sib xyaw ua ke ntawm cov yam ntxwv, suav nrog kev tiv taus corrosion, tiv taus cua sov thiab lub zog qaug zog, ua rau lawv zoo tagnrho rau ntau yam kev siv.
Hauv kev lag luam aerospace, cov hlau gland ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv dav hlau uas yuav tsum tiv taus qhov nyuaj ntawm kev ya dav hlau. Txij li cov hniav turbine mus rau cov khoom siv, cov hlau gland lub zog zoo dua thiab kev tiv taus cua sov ua kom lub dav hlau ua haujlwm tau zoo hauv qab cov xwm txheej nyuaj tshaj plaws. Tsis tas li ntawd, qhov tseeb uas cov khoom siv hlau raug kaw ua rau muaj kev nyab xeeb thiab kev ua haujlwm zoo ntawm cov kab ke aerospace.
Hauv kev kho mob, cov hlau glandular ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv phais thiab cov khoom siv. Qhov sib xws ntawm qee cov hlau gland alloys, ua ke nrog lawv lub zog thiab kev ua kom raug, ua rau lawv zoo tagnrho rau kev siv xws li orthopedic implants, cov khoom siv plawv thiab cov cuab yeej phais. Cov hlau glandular muaj peev xwm tiv taus cov xwm txheej hnyav hauv tib neeg lub cev thaum tswj hwm qhov tseeb ntawm qhov ntev, uas yog qhov tseem ceeb rau kev ua kom tiav ntawm cov txheej txheem kho mob.
Ntxiv rau kev siv rau hauv aerospace thiab kev kho mob, cov hlau gland nrhiav tau qhov chaw hauv ntau lwm yam lag luam, suav nrog tsheb, lub zog thiab kev tiv thaiv. Txawm hais tias txhim kho kev ua tau zoo ntawm cov tsheb ua haujlwm siab, ua kom muaj kev rho tawm lub zog zoo, lossis ua kom ntseeg tau tias muaj kev ntseeg siab ntawm cov kab ke tiv thaiv, cov hlau gland txuas ntxiv thawb cov ciam teb ntawm kev tsim kho thiab kev tsim khoom.
Hauv kev xaus, lub zog ntawmcov hlau qog nyob rau hauv nws qhov kev sib xyaw ua ke zoo kawg nkaus ntawm lub zog thiab kev ua kom raug. Raws li cov khoom siv uas muaj lub zog thiab qhov tseeb, cov hlau gland txuas ntxiv tsav tsheb tsim kho tshiab thiab kev nce qib hauv ntau yam lag luam. Nws lub peev xwm los tiv taus cov xwm txheej hnyav thaum tswj hwm cov qauv nruj ua rau nws yog qhov khoom muaj nqis tseem ceeb hauv kev nrhiav kev ua haujlwm engineering thiab kev tsim khoom zoo tshaj plaws.
