Helium yog cov tshuaj lom neeg nrog lub cim nws thiab atomic naj npawb 2. Nws yog cov tsis muaj tshuaj, tsis muaj ntsej muag, tsis muaj ntsej muag, tsuas yog ua kom me ntsis hauv dej. Helium siab rau hauv cov cua yog 5.24 x 10-4 los ntawm cov feem pua. Nws muaj qis tshaj plaws npau npau thiab yaj tau cov ntsiab lus ntawm txhua lub caij, thiab muaj tsuas yog siv roj, tshwj tsis yog nyob rau hauv cov neeg mob khaub thuas.
Qhov Kub Kub Kub Txias
Aeronautics thiab lwm yam qub txeeg qub teg
Helium kuj tseem siv rau hauv cov zais pa thiab airships. Vim tias helium yog sib dua ntau dua cua, airships thiab cov zais pa muaj helium. Helium muaj qhov kom zoo dua ntawm kev ua tsis yog, txawm hais tias hydrogen yog cov buoyant ntau dua thiab muaj qhov khiav dim ntawm daim nyias nyias. Another secondary use is in rocket technology, where helium is used as a loss medium to displace fuel and oxidizer in storage tanks and condense hydrogen and oxygen to make rocket fuel. It could also be used to remove fuel and oxidizer from ground support equipment before launch, and could pre-cool liquid hydrogen in the spacecraft. Nyob rau hauv Saturn v foob pob hluav taws xob siv hauv Apollo program, txog 370,000 lo lo lus sau lo lo lus (13 lab cubic feet) ntawm Helium yuav tsum tau tsim tawm.
Kev Tshawb Nrhiav Kev Tshawb Nrhiav Kev Tshawb Nrhiav thiab Kev Tshawb Xyuas Nrhiav tau
Lwm txoj kev lag luam kev siv helium yog kev pom zoo. Kev tshawb xyuas xau yog siv los kuaj cov dej xau hauv cov tshuab muaj cov kua thiab roj av. Because helium diffuses through solids three times faster than air, it is used as a tracer gas to detect leaks in high-vacuum equipment (such as cryogenic tanks) and high-pressure vessels. Cov khoom tau muab tso rau hauv chav tsev, uas yog tom qab ntawd tau khiav tawm thiab muaj kev helium. Even at leakage rates as low as 10-9 mbar•L/s (10-10 Pa•m3 / s), helium escaping through the leak can be detected by a sensitive device (a helium mass spectrometer). Cov txheej txheem ntsuas feem ntau yog siv hluav taws xob thiab yog hu ua Helium kev sib koom ua ke ntsuas. Lwm qhov, txoj kev piv tau yooj yim dua yog sau cov khoom hauv cov lus nug nrog helium thiab pom kev tshawb nrhiav rau cov dej xau siv cov khoom siv xuas tes.
Helium yog siv rau kev pom kom meej nrawm vim tias nws yog Molecule tsawg tshaj plaws thiab yog monatomic molecule, yog li helium leaks yooj yim. Helium gas is filled into the object during leak detection, and if a leak occurs, the helium mass spectrometer will be able to detect the location of the leak. Helium can be used to detect leaks in rockets, fuel tanks, heat exchangers, gas lines, electronics, TELEVISION tubes and other manufacturing components. Kev pom kom pom tseeb siv Helium tau siv thawj zaug thaum lub sijhawm Manhattan txoj haujlwm los kuaj cov dej ntws ntawm Uranium txhawb cov nroj tsuag. Kev Tshawb Fawb Kev Kho Mob tuaj yeem hloov nrog hydrogen, nitrogen, lossis sib xyaw ntawm hydrogen thiab nitrogen.
Vuam thiab Hlau Ua Hauj Lwm
Ib qho ntawm cov chaw nquag tshaj plaws ntawm kev txhim kho yog stainless hlau vuam. Helium yog cov roj hauv qab, uas txhais tau tias nws tsis yauv muaj kev sib raug zoo thaum raug lwm cov tshuaj yeeb dej caw. Cov xeeb ceem no yog qhov tshwj xeeb tshaj yog nyob rau hauv vuam tiv thaiv gases.
Helium kuj ua kom sov zoo. Qhov no yog vim li cas nws yog feem ntau siv nyob rau hauv welds uas siab dua cov kev tawm tshiab yuav tsum txhim kho lub wettability ntawm weld. Helium tseem muaj txiaj ntsig zoo rau kev nrawm.
Helium feem ntau yog tov nrog Argon hauv kev sib txawv hauv cov roj tiv thaiv kom tau txais txiaj ntsig zoo ntawm cov khoom zoo ntawm ob qho khoom siv. Helium, piv txwv li, ua raws li cov roj tiv thaiv kom pab muab cov dav dav thiab khawb av ua rau nkag mus hauv vuam. Tab sis Helium tsis muab kev tu uas Argon ua.
Raws li qhov tshwm sim, cov tuam ntxhab cov hlau feem ntau xav sib xyaw sib cav nrog helium ua ib feem ntawm lawv cov txheej txheem ua haujlwm. Kom muaj roj thaiv cov hlau arc vuam, Helium yuav suav 25% mus rau 75% ntawm cov roj sib tov hauv kev helium / argon sib tov. By adjusting the composition of the protective gas mixture, the welder can influence the heat distribution of the weld, which in turn affects the shape of the cross section of the weld metal and the welding speed.
Hauv semiconductor kev lag luam
Helium Muag Khoom Ntim Ntim (2016-2027)
Ntau lub tuam txhab muaj ob peb lub chaw ua haujlwm, tab sis lawv feem ntau tsis ze rau lawv cov khoom lag luam cov neeg siv khoom lag luam. Yog li ntawd, cov khoom muaj tus nqi thauj mus los.
Txij li thawj tsib xyoos, kev tsim khoom tau nce qeeb heev. Helium yog qhov tsis rov qab lub zog loj, thiab cov kev cai nyob rau hauv qhov chaw ua rau cov teb chaws tsim kom ntseeg tau tias nws tau siv txuas ntxiv. Qee cov kwv yees tias Helium yuav khiav tawm yav tom ntej.
Cov kev lag luam muaj feem ntau ntawm cov neeg tuaj yeem siv thiab xa tawm. Yuav luag txhua lub tebchaws siv Helium, tab sis tsuas yog ob peb muaj helium reserves.
Helium muaj ntau yam kev siv thiab yuav muaj nyob rau hauv ntau thiab ntau daim teb. Muab cov tsis txaus ntseeg ntawm cov khoom siv ntuj, thov rau Helium yuav nce rau yav tom ntej, xav tau cov cai tsim nyog. Helium Tus nqi yuav tsum tau txuas ntxiv nce siab txij 2021 txog 2026, txij li $ 13,53 / M3 (2020) rau $ 19.09 / M3 (2027).
Kev lag luam cuam tshuam los ntawm kev lag luam thiab txoj cai. As the global economy recovers, more and more people are concerned about improving environmental standards, especially in underdeveloped regions with large populations and fast economic growth, the demand for helium will increase.
Hl cryogenic khoom
HL cryogenic cov khoom siv uas tau tsim nyob rau xyoo 1992 yog ib hom neeg muaj feem cuam tshuam rau nws cry cryogenic cov cuab yeej siv cryogenic khoom Co., Ltd. Ua cov khoom siv cryogenic tau cog lus rau cov qauv siv thiab tsim cov tshuab hluav taws xob siab cryogenic piping system thiab cuam tshuam cov khoom siv txhawb nqa kom tau raws li cov neeg siv khoom ntau. Lub tshuab nqus tsev insulated yeeb nkab thiab yoog raws tau tsim nyob rau hauv lub tshuab hluav taws xob siab tshwj xeeb, uas yog siv rau kev hloov pauv ntawm cov pa oxygen, ua kua nitrogen , Ua Kua Argon, kua hydrogen, kua helium, liquefas roj ceg thiab liquefied xwm roj lng.
