Lwm qhov tshwj xeeb ntawm kev ntim khoom tuaj yeem muab tau raws li cov neeg siv khoom xav tau

Kev lag luam hluav taws xob Argon 99.999% purity Ar

Ar, Feem ntau qhov chaw ntawm argon yog huab cua sib cais cog. Cua muaj approx. 0.93% (ntev) argon. Cov kwj deg argon uas muaj txog li 5% oxygen raug tshem tawm ntawm cov huab cua sib cais los ntawm cov kab ke thib ob ("sidearm"). Lub crude argon yog tom qab ntawd ntxiv purified los tsim ntau yam kev lag luam qib xav tau. Argon kuj tseem tuaj yeem rov qab los ntawm cov pa tawm ntawm qee cov nroj tsuag ammonia.

Argon yog cov roj tsawg uas siv dav hauv kev lag luam. Nws qhov xwm txheej tsis muaj zog heev, thiab nws tsis tuaj yeem hlawv lossis pab hlawv. Nyob rau hauv lub dav hlau tsim, shipbuilding, atomic zog kev lag luam thiab machinery kev lag luam sectors, argon yog feem ntau siv raws li vuam tiv thaiv roj rau tshwj xeeb hlau, xws li txhuas, magnesium, tooj liab thiab nws alloys thiab stainless hlau, los tiv thaiv cov vuam qhov chaw los ntawm oxidized los yog nitrided los ntawm huab cua.

Cov lus qhia kev nyab xeeb

Cov ntsiab lus thaum muaj xwm txheej ceev: Tsis muaj roj, lub tog raj kheej lub thawv yog yooj yim rau overpressure thaum rhuab, muaj kev pheej hmoo ntawm tawg. Cryogenic kua tuaj yeem ua rau frostbite. GHS Hazard Qeb: Raws li Kev Tshawb Fawb Tshuaj, Daim Ntawv Ceeb Toom thiab Kev Ceeb Toom Specification series, cov khoom no yog cov roj hauv siab - compressed gas.
Lus ceeb toom: ceeb toom
Cov ntaub ntawv txaus ntshai: Gas nyob rau hauv siab, yog tias cua sov tuaj yeem tawg.
Cov kev ceev faj:
Kev ceev faj: Khaws kom deb ntawm qhov chaw kub, qhib nplaim taws, thiab qhov chaw kub. Tsis haus luam yeeb hauv chaw ua haujlwm.
Cov lus teb raug xwm txheej: txiav tawm qhov xau, tsim nyog qhov cua, ua kom nrawm nrawm.
Kev ruaj ntseg cia: Tsis txhob tshav ntuj thiab cia rau hauv qhov chaw muaj cua zoo.
Kev pov tseg: Cov khoom no lossis nws lub thawv yuav tsum muab pov tseg raws li cov cai hauv zos
Kev phom sij ntawm lub cev thiab tshuaj lom neeg: compressed tsis-flammable gas, lub tog raj kheej ntim yog yooj yim rau overpressure thaum rhuab, thiab muaj kev pheej hmoo ntawm tawg. High concentration inhalation yuav ua rau suffocation.
Kev raug rau cov kua argon tuaj yeem ua rau frostbite.
Kev phom sij rau kev noj qab haus huv: Tsis muaj tshuaj lom ntawm atmospheric siab. Thaum lub siab concentration, ib feem ntawm lub siab yog txo thiab lub chamber ua tsis taus pa tshwm sim. Cov concentration yog ntau tshaj 50%, ua rau cov tsos mob hnyav; Hauv ntau dua 75% ntawm cov neeg mob, kev tuag tuaj yeem tshwm sim hauv feeb. Thaum cov concentration hauv huab cua nce, thawj zaug ua pa nrawm, tsis muaj concentration, thiab ataxia. Qhov no yog ua raws li qaug zog, tsis xis nyob, xeev siab, ntuav, coma, convulsions, thiab txawm tuag. Cov kua argon tuaj yeem ua rau tawv nqaij frostbite: qhov muag sib chwv tuaj yeem ua rau mob.
Environmental harms: Tsis muaj kev puas tsuaj rau ib puag ncig.
