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

Oxygen

Oxygen tau txais ntawm kev lag luam nplai los ntawm liquefaction thiab tom qab cua distillation. Rau cov pa purity siab heev, nws yog ib qho tsim nyog yuav tsum dhau los ntawm theem nrab purification thiab distillation theem kom tshem tawm cov khoom ntawm huab cua sib cais cog. Xwb, high-purity oxygen tuaj yeem tsim los ntawm electrolyzing dej. Tsawg purity oxygen kuj tuaj yeem tsim siv siv tshuab membrane.

Kev nug

Oxygen yog ib qho tsis muaj xim, tsis muaj ntxhiab, tsis muaj roj. Cov txheeb ze ntom ntom ntawm cov pa (cua = 1) ntawm 21.1 ° C thiab 101.3kPa yog 1.105, thiab qhov ceev ntawm cov kua ntawm boiling point yog 1141kg / m3. Oxygen tsis yog tshuaj lom, tab sis raug rau cov concentrations siab tuaj yeem cuam tshuam rau lub ntsws thiab lub paj hlwb hauv nruab nrab. Cov pa tuaj yeem thauj tau ntawm qhov siab ntawm 13790kPa raws li cov pa roj uas tsis yog kua lossis ua kua ua kua. Ntau cov tshuaj tiv thaiv oxidation hauv kev lag luam tshuaj siv cov pa ntshiab huv es tsis txhob siv cua kom tau txais txiaj ntsig los ntawm cov tshuaj tiv thaiv ntau dua, kev sib cais cov khoom yooj yim dua, cov khoom siv ntau dua los yog cov khoom siv me me.
