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

Nitrogen

Nitrogen yog tsim nyob rau hauv ntau ntawm cov huab cua sib cais cov nroj tsuag uas liquefy thiab tom qab distil cua rau nitrogen, Oxygen thiab feem ntau yog Argon. Yog tias xav tau nitrogen ntau heev, cov nitrogen uas tsim tau yuav tsum tau mus dhau ntawm cov txheej txheem purification thib ob. Qhov qis dua ntawm nitrogen purities kuj tuaj yeem tsim nrog cov txheej txheem membrane, thiab nruab nrab mus rau siab purities nrog siab viav vias adsorption (PSA) cov txheej txheem.

Kev nug

Nitrogen yog siv dav hauv kev lag luam chemical rau pam vov, purging thiab siab hloov cov tshuaj flammable. High-purity nitrogen yog siv dav los ntawm kev lag luam semiconductor raws li kev tshem tawm lossis cov pa roj carbon monoxide, thiab los npog cov khoom siv xws li cov cub tawg thaum tsis tsim khoom. Nitrogen yog cov tsis muaj xim, tsis muaj ntxhiab, tsis qab, tsis muaj tshuaj lom inert gas. Cov kua nitrogen tsis muaj xim. Tus txheeb ze ntom ntom ntawm cov roj ntawm 21.1 ° C thiab 101.3kPa yog 0.967. Nitrogen tsis yog flammable. Nws tuaj yeem ua ke nrog qee cov hlau tshwj xeeb xws li lithium thiab magnesium los tsim nitrides, thiab tuaj yeem ua ke nrog hydrogen, oxygen thiab lwm yam khoom ntawm qhov kub thiab txias. Nitrogen yog ib qho yooj yim smothering tus neeg sawv cev.
