Iqondo lokushisa kwe-nitrogen

I-nitrojeni yotywala yintsimbi ebonakalayo kunye nesisindo esithile se-0.808 g / cm³. Le ngenye yeendawo ezidibeneyo apho i-nitrogen ingaba khona, indawo yayo yokubilisa i--195.75 ° C. I-nitrojeni yotywala ayinobuthi kwaye inokutshabalalisa.

Isici sokusebenza kunye nokugcinwa kwe-nitrojeni yamanzi kukuba xa ushushu, yanda kakhulu, umzekelo, ngokunyuka kweqondo lokushisa okuphantsi kwe-20 C, malunga neelitha ezingama-700 zegesi zenziwe kwimizuzu enye yezinto. Ngoko ke, ukugcinwa kunye nokuthutha kusetyenziswa izitya ezikhethekileyo, izitya ezithiwa yi- Dewar, ezinika ukuxhomekeka okungekhoyo.

I-nitrojeni yotywala ifumane isicelo esikhulu kwiindawo ezahlukahlukeneyo zoluntu, ngeendlela ezininzi, ububanzi bokusetyenziswa kubangelwe kwiipropati ezinjengezinga lokushisa kwe-nitrogen. Isetyenziswe kwishishini apho kuyimfuneko ukusebenzisa ifeknoloji ye-cryogenic metal cutting. Iqondo eliphantsi kakhulu le -nitrojeni yamanzi livumela ukuba lisetyenziswe kwiqhwa elikhulu, kwaye kule nqanaba lifanelekile izinto zombini kunye nezinto eziphilayo, kuquka izinto eziphilayo.

Kukho ezinye izicelo: ukulwa komlilo kunye nokupholisa amaqela ahlukeneyo kunye nezixhobo zobuchwepheshe, ukwenziwa kwee-cell ukulungiswa kweeseli, ukugqithisa.

Ngomngcipheko we-atmospheric, ukushisa kwe-nitrogen yamanzi kungaphantsi kobushushu be-oxygen nge-degrees ezili-10, ngoko ke, njengommiselo, i-sediment ye-condensate yezinto ezinokuthi ingabonwa kwiindonga zeempahla.

Ngenxa yokuba iphulo lokubilisa le- nitrojeni kwimeko yelwelo -195.8 ° C, elingaphantsi kwelo-oksijini ye-oksijini, apho i-183 ° C, ngenxa yendlela yokusebenzisana ngayo, umoya omanzi uphuthunyiswa ngokukhawuleza kwi-oksijini. Uhlobo olufanayo lokushisa lubonisa ukunyuka okukhulu kwe-nitrojeni yamanzi, xa kuthelekiswa ne -oksijeni yamanzi.

Ngokwenene nayiphi na amaqondo okushisa aphezulu kwexabiso le-nitrogen yamanzi angabonwa kulo mvavanyo olandelayo. Kufuneka ukuba le block block aluminium, ukupholisa, ukuba iqhutywe ngomoya okhulayo.

Kwiikhompyutheni zanamhlanje, ukushisa kwe-nitrojeni yamanzi, njengepropati ephambili yale nkunkuma, kubangele isicelo esiphezulu se-semiconductors kwimboniselo yombaneli kunye negesi, ngoko ke, fumana ukupholisa okuthembekileyo.

Ngomgaqo ofanayo, ukusetyenziswa kwezinto njengengxenye yemimandla eyahlukeneyo yokulwa nomlilo isekelwe. Ngendlela yokucinywa komlilo, i-nitrojeni ikhuphuka ngokukhawuleza kwaye, ngoko, ikhupha i-oksijeni, ngenxa yokuyeka ukufikelela kwi-oksijini emlilweni, umlilo uphahla kwaye uyeka ngokupheleleyo. Ngenxa yolu hlobo, ukucinywa komlilo we-nitrogen kubonwa namhlanje njengempumelelo ngakumbi kune-carbon dioxide. Ngokusetyenziswa kwezobuchwepheshe, iqondo eliphezulu lokulondolozwa kwexabiso lezinto eziphathekayo lifezekisiwe.

Ngokuqhelekileyo, umphumo we-nitrojeni ye-liquid ingabonwa phantse wonke umntu, ukuba ubeka ingqalelo kwiimifanekiso zemoya ezisetyenzisiweyo ekufayeleni iifrimu zanamhlanje. Ngokomzekelo, kwi-movie "Terminator", imiphumo efunyenwe ngoncedo lwe-nitrojeni yamanzi (amafowuni, apho kufakwa khona izinto ezinqamlekileyo ngokubonakalayo) zisetyenziswa kakhulu. Kodwa esi siphumo sinokuba nolwazi olungakumbi. Umzekelo, ukushisa okuphantsi kwe-nitrojeni kuvumela ukuba isetyenziswe ngokukhenkcela ngokukhawuleza komntu onobungozi. Oku sikwazi ukuyigcina ngexesha lokuncintisana kwezemidlalo, xa umdlali ekhuselekile, kwaye unikwa uncedo lokuqala lokuqala ngeentlungu ze-aerosol zendawo.

Eyona nto ibaluleke kakhulu, ukuba ingenangqungquthela, ngoku kusetyenziswe kwezinto njengendlela yokuphila epholileyo, ngenjongo yokutshatyalaliswa kwazo, nokulondolozwa kwezinto eziphilayo.

Ngelo xesha, zombini e-US naseRashiya, kukho iikhampani ezibandakanyekayo kwiqhwa le-cryogenic yabantu kunye nezilwanyana kwizorhwebo.
