Dab tsi yog kua argon siv rau

Ib. Puas yog kua argon txaus ntshai?

Ua ntej tshaj plaws,kua argonyog xim tsis muaj xim, tsis qab, tsis muaj ntxhiab, tsis muaj tshuaj lom inert gas, uas tsis muaj teeb meem rau tib neeg lub cev thiab ib puag ncig. Txawm li cas los xij, ntawm qhov siab siab, argon muaj qhov ua tsis taus pa. Thaum cov concentration ntawm argon nyob rau hauv cov huab cua siab tshaj 33%, muaj kev txaus ntshai ntawm suffocation. Thaum cov argon concentration ntau tshaj 50%, cov tsos mob hnyav yuav tshwm sim, thiab thaum lub concentration nce mus txog 75%, kev tuag tuaj yeem tshwm sim hauv ob peb feeb. Nyob rau tib lub sijhawm, kev sib cuag ntawm daim tawv nqaij nrog kua argon tuaj yeem ua rau frostbite, thiab qhov muag qhov muag tuaj yeem ua rau mob.

二.Cov kua argon yog qib dab tsi?

Lub purity ntawm peb cov roj argon suav nrog 99.99%, 99.999%, 99.9999% thiab argon sib xyaw roj, uas tuaj yeem ua tau raws li cov kev xav tau ntawm qib kev lag luam thiab qib hluav taws xob.

Kev siv ntau ntawm cov kua argon:

1. Coolant:Ua kua argonyog cov kua roj kub uas tsis tshua muaj kub nrog qhov kub ntawm -185.7 ° C, uas yog ib qho ntawm cov ntsiab lus nrog qhov kub siab tshaj plaws uas paub txog tam sim no. Yog li ntawd, kua argon yog dav siv nyob rau hauv cryogenic thwmsim thiab technologies, xws li superconducting electronics, nuclear magnetic resonance, siab zog physics thiab lwm yam teb.
2. Kev tiv thaiv roj: Cov kua argon kuj tseem tuaj yeem siv los ua tus neeg sawv cev tiv thaiv roj, uas tuaj yeem tiv thaiv qee qhov yooj yim oxidized thiab corroded hlau thiab alloys, xws li tooj liab, aluminium, magnesium, thiab lwm yam. Thaum lub sij hawm ua cov hlau no, kua argon tuaj yeem tiv thaiv. lawv los ntawm reacting nrog oxygen thiab dej vapor hauv huab cua, yog li ua kom cov khoom zoo.
3. Kev ua zaub mov: Cov kua argon kuj tuaj yeem siv rau hauv kev ua zaub mov, xws li cov khoom noj khov, cov dej khov, thiab lwm yam. Hauv cov ntawv thov no, cov kua argon tuaj yeem khov cov zaub mov sai, khaws nws cov freshness thiab saj.
4. Kev lag luam hluav taws xob: Cov kua argon kuj tuaj yeem siv rau hauv kev lag luam hluav taws xob, xws li kev tsim khoom semiconductor, hluav taws xob cov khoom siv hluav taws xob, thiab lwm yam. Hauv cov ntawv thov no, cov kua argon tuaj yeem siv los ntxuav, txias thiab tiv thaiv cov khoom siv hluav taws xob, yog li tswj cov khoom zoo thiab kev ua tau zoo.
5. Rocket propellant: Cov kua argon kuj tuaj yeem siv los ua lub foob pob hluav taws vim nws qhov kub kub tshaj tawm thiab muaj zog ceev ceev. Cov kua argon tuaj yeem sib xyaw nrog cov pa oxygen los tsim cov nplaim hluav taws kub thiab kub siab, uas tuaj yeem ua kom muaj zog thrust.

四.Yuav siv thiab khaws cov kua argon li cas?

Kev ceev faj rau kev ua haujlwm thiab pov tseg: kev ua haujlwm airtight, txhim kho qhov cua, nruab nrog cov khoom siv cua txias thaum muaj xwm ceev, thiab cov neeg ua haujlwm yuav tsum tau txais kev cob qhia tshwj xeeb. Ua haujlwm nrog daim ntawv pov thawj thiab nruj me ntsis raws li cov txheej txheem ua haujlwm thaum lub sijhawm ua haujlwm. Thaum sau, lub filling ceev yuav tsum tau tswj. Lub sijhawm ua haujlwm tsis pub tsawg tshaj 30 feeb. Cov kua dej argon los tiv thaiv frostbite.
Kev ceev faj rau kev khaws cia: Khaws rau hauv qhov chaw tso cua, kom deb ntawm qhov hluav taws kub, qhov chaw cua sov, thiab lub tog raj kheej roj. Kev ntsuas yuav tsum tau ua kom tsis txhob poob rau hauv av. Cia kub yuav tsum tsis pub tshaj 30 ° C. Lub chaw cia khoom yuav tsum tau nruab nrog cov khoom siv kho mob thaum muaj xwm ceev.

Cov ntsiab lus: Muaj ntau txoj hauv kev los npaj cov kua argon, feem ntau siv txoj hauv kev yog npaj los ntawm huab cua sib cais. Txoj kev sib cais huab cua yog cais cov pa oxygen, nitrogen thiab lwm cov pa hauv huab cua kom tau cov kua argon.

Tsis tas li ntawd, muaj lwm txoj hauv kev los npaj kua argon los ntawm liquefied natural gas. Liquefied natural gas yog compressed natural gas rau hauv lub xeev ua kua, thiab ces cais cov kua argon nyob rau hauv lub xeev kua los ntawm kev sib cais technology.

Txawm hais tias cov kua argon muaj cov haujlwm tseem ceeb thiab siv hauv ntau qhov chaw, nws kuj muaj qee yam kev phom sij. Cov kua argon yog cov roj ruaj khov ntawm qhov kub thiab txias, tab sis nyob rau hauv kev kub siab, kub thiab lwm yam kev mob, kua argon yuav tsis ruaj khov, ua rau muaj kev phom sij xws li tawg thiab hluav taws. Yog li ntawd, thaum siv cov kua argon, nws yog ib qho tsim nyog yuav tsum ua raws li cov cai tswj kev nyab xeeb kom ruaj ntseg ntawm cov neeg ua haujlwm thiab cov khoom siv.
