Thaum lub sij hawm Tuam Tshoj ob zaug, ntxiv dag zog thiab nce helium ntau lawm tau muab tso rau hauv cov txheej txheem
Apr 01, 2024
Hauv kev lag luam, helium yog lub npe hu ua "golden gas" thiab "gas chip" thiab tau dav siv nyob rau hauv high-tech teb xws li kua roj foob pob ua ntxaij, manned tob dhia dej, semiconductor manufacturing, nuclear magnetic resonance, thiab niaj hnub precision analytical instruments. . Kev lag luam helium yog ib qho kev lag luam raws li kev lag luam uas txhawb nqa thiab cuam tshuam rau txoj kev loj hlob ntawm kev lag luam tshiab. Yuav ua li cas los ntsuas thiab siv cov khoom tsim tau zoo tshiab, txhawb kev tsim kho tshiab ntawm helium kev lag luam thiab txhim kho qhov zoo thiab kev ua haujlwm ntawm helium kev lag luam tau nkag mus rau hauv lub zeem muag ntawm Tuam Tshoj Ob Lub Sijhawm, arousing lub mloog thiab xav ntawm delegates.
Helium yog ib qho khoom siv tswv yim. Ua ntej, cov peev txheej tsis tshua muaj. kuv lub teb chaws yog ib lub teb chaws txom nyem. Helium reserves tsuas yog suav txog 2% ntawm lub ntiaj teb tag nrho, tab sis kev thov nyiaj rau 11% ntawm tag nrho lub ntiaj teb. Qhov thib ob, nws yog dav siv. Helium yog dav siv nyob rau hauv lub teb chaws tiv thaiv kev lag luam thiab high-tech teb xws li kua roj foob pob ua ntxaij, spacecrafts, supersonic aircraft, manned tob dives, semiconductor manufacturing, quantum computers, nuclear magnetic resonance, thiab niaj hnub precision analytical instruments. Nws yog hu ua "Gas Chip".
Nyob rau hauv qhov tseeb, helium tsis yog mysterious txhua. Nws yog nquag nquag hauv peb lub neej. Helium yog siv nyob rau hauv balloons uas cov me nyuam nyiam ua si nrog, vuam ntawm cov chaw tsim kho, kev kho mob ultrasound thiab nuclear magnetic resonance, thiab optical fibers rau kev sib txuas lus. Helium tuaj yeem siv los sau cov qhov muag teev thiab cov raj neon. Nws kuj yog ib qho zoo tagnrho roj rau balloons thiab airships. Nws tseem tuaj yeem sib xyaw nrog cov pa oxygen thiab siv los ua cov pa ua pa rau cov neeg dhia dej. Helium purification technology yog heev xav tau thiab nyuaj.
Technological innovation txhim khu kev ywj pheej controllability ntawm industrial saw
Txhawm rau tsim cov khoom tsim tawm tshiab raws li cov xwm txheej hauv zos, peb yuav tsum tsis tsuas yog tuav lub siab ntawm kev hloov kho thev naus laus zis tshiab thiab qhib kev txhim kho tshiab, tab sis kuj tseem siv cov thev naus laus zis tshiab los hloov pauv thiab txhaj tshuaj tshiab tseem ceeb rau hauv kev lag luam ib txwm muaj, txhawb nqa kev hloov kho dua tshiab. ntawm cov khoom tsim tau, thiab "tiav tus tshiab" thiab "rov kho dua qub" "Peb yuav tsum ua haujlwm tib yam.
Nyob rau hauv xyoo tas los no, Gansu tau siv zog tsim kev lag luam hauv tsev, ywj siab thiab tswj tau helium kev lag luam thiab lwm yam thev naus laus zis, ua kom muaj kev tsim kho ntawm helium kev lag luam system thiab txhim kho kev ywj pheej thiab kev muaj peev xwm ntawm cov saw hlau. Nov yog ib txoj hauv kev los tsim cov khoom tsim tawm tshiab.
99.9999% nyuaj npaum li cas? Nws yog ib qho nyuaj heev rau purify helium cov khoom rau 99.9999%. Thawj kauj ruam yog kom dhau lub impurity tswj theem, uas txhais tau hais tias tag nrho cov nqi ntawm impurities yuav tsum tau tswj kom tsawg tshaj li ib feem ntawm ib lab, uas yog sib npaug rau tag nrho cov impurities nyob rau hauv ib tug standard football teb tsis pub tshaj qhov loj ntawm ib tug. npib. Lub hom phiaj yog los daws qhov teeb meem ntawm kev ua kom zoo ntawm cov impurities xws li nitrogen thiab hydrogen hauv neon-helium sib xyaw roj. Nyob rau tib lub sijhawm, kev kho tshwj xeeb ntawm cov khoom siv thauj mus los thiab cov khoom ntim khoom yuav tsum tau ua kom tsis txhob muaj kev ua qias tuaj. Cov kauj ruam thib ob yog kom dhau qhov kev sib cais ntawm neon thiab helium, thiab siv qhov sib txawv ntawm qhov sib txawv ntawm neon thiab helium kom kov yeej cov teeb meem kev lag luam xws li tsim kom muaj qhov kub thiab txias ntawm qhov chaw ua haujlwm ultra-low kub adsorption kom ua tiav. high-efficiency sib cais ntawm neon thiab helium. Thaum tsim helium, lub purity ntawm neon roj kuj yuav tsum tau txhim kho. Purified rau 99.9999%. Qhov kev daws teeb meem no tau muaj txoj cai ywj pheej ntawm kev txawj ntse thiab tau mus txog qib siab thoob ntiaj teb.
Peb tus kheej tsim chav-kub membrane helium extraction thev naus laus zis tau ua rau nws muaj peev xwm rho tawm qib qis helium-muaj cov khoom siv roj ntsha uas yav dhau los tsis muaj txiaj ntsig. Cov thev naus laus zis no tau qhib cov qauv tshiab helium extraction uas tsim nyog rau cov khoom siv roj av tiag tiag hauv peb lub tebchaws thiab txhim kho peb lub teb chaws Helium tus kheej txaus. Nyob rau hauv lub neej yav tom ntej, peb yuav txuas ntxiv nqis peev hauv kev tshawb fawb thiab kev tsim kho thiab siv cov thev naus laus zis no rau tag nrho cov roj uas muaj helium, txhawm rau ua kom txhua qhov hais tau.
