High-purityargonthiab ultra-ntshiabargonyog cov pa roj tsawg uas tau siv dav hauv kev lag luam. Nws qhov xwm txheej yog qhov tsis muaj zog, tsis kub hnyiab lossis txhawb kev sib txuas. Nyob rau hauv lub dav hlau tsim, shipbuilding, atomic zog kev lag luam thiab machinery kev lag luam sectors, thaum welding tshwj xeeb hlau, xws li txhuas, magnesium, tooj liab thiab nws alloys, thiab stainless hlau, argon feem ntau yog siv raws li vuam txij nkawm roj los tiv thaiv vuam qhov chaw los ntawm oxidized. los yog nitridated los ntawm huab cua.
Nyob rau hauv cov nqe lus ntawm hlau smelting, oxygen thiabargontshuab yog qhov tseem ceeb rau kev tsim cov hlau zoo. Kev siv argon ib tuj ntawm cov hlau yog 1-3m3. Tsis tas li ntawd, kev smelting ntawm cov hlau tshwj xeeb xws li titanium, zirconium, germanium, thiab kev lag luam hluav taws xob kuj xav tau argon ua cov roj tu.
Lub 0.932% argon uas muaj nyob rau hauv cov huab cua muaj ib tug boiling point ntawm oxygen thiab nitrogen, thiab cov ntsiab lus siab tshaj nyob rau hauv nruab nrab ntawm lub pej thuam ntawm cov huab cua sib cais cog yog hu ua argon feem. Cais cov pa thiab nitrogen ua ke, rho tawm cov argon feem, thiab ntxiv cais thiab purify, kuj tuaj yeem tau txais argon los ntawm cov khoom. Rau tag nrho cov khoom siv cua sib cais tsis tshua muaj siab, feem ntau 30% mus rau 35% ntawm argon hauv cov huab cua ua haujlwm tuaj yeem tau txais raws li cov khoom lag luam (cov txheej txheem tshiab tuaj yeem ua kom cov argon rho tawm ntau tshaj 80%); rau nruab nrab siab cua sib cais cov cuab yeej, vim qhov nthuav dav ntawm cov huab cua nkag mus rau hauv cov pej thuam qis tsis cuam tshuam rau cov txheej txheem rectification ntawm cov pej thuam sab saud, thiab qhov kev rho tawm ntawm argon tuaj yeem ncav cuag li 60%. Txawm li cas los xij, tag nrho cov txheej txheem huab cua ntawm cov khoom siv cua sib cais me me yog qhov me me, thiab cov argon uas tuaj yeem tsim tau raug txwv. Txawm hais tias nws tsim nyog los teeb tsa cov khoom siv argon extraction yog nyob ntawm cov xwm txheej tshwj xeeb.
Argonyog ib qho roj inert thiab tsis muaj kev puas tsuaj rau tib neeg lub cev. Txawm li cas los xij, tom qab siv hauv kev lag luam, cov pa hluav taws xob tsim tawm yuav ua rau muaj kev puas tsuaj loj rau tib neeg lub cev, ua rau silicosis thiab qhov muag puas.
Txawm hais tias nws yog ib qho inert gas, nws kuj yog ib tug suffocating gas. Inhalation ntawm ib tug loj npaum li cas yuav ua rau suffocation. Lub chaw tsim khoom yuav tsum tau ua kom cua, thiab cov kws tshaj lij uas koom nrog cov roj argon yuav tsum tau kuaj xyuas cov kab mob ua haujlwm tsis tu ncua txhua xyoo kom ntseeg tau lawv txoj kev noj qab haus huv.
Argonnws tus kheej yog non-toxic, tab sis muaj ib tug suffocating nyhuv ntawm high concentrations. Thaum lub concentration ntawm argon nyob rau hauv cov huab cua yog 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 cov concentration nce mus txog 75% lossis siab dua, nws tuaj yeem tuag hauv ob peb feeb. Cov kua argon tuaj yeem ua mob rau ntawm daim tawv nqaij, thiab qhov muag pom tuaj yeem ua rau mob.
