Ijeneretha yeNitrogen Ekukhiqizweni Okufushane

Nasi incazelo eningiliziwe yokuthi kungani i-nitrogen isetshenziswa nokuthi isetshenziswa kanjani:

1. Inhloso Eyinhloko: Ukunciphisa (Ukunciphisa umoya)

Lona umsebenzi obaluleke kakhulu.

• Inkinga:Ngesikhathi senqubo yokukhiqiza (ehilela ukushisa, ukuxuba, kanye nokupholisa ngokushesha kwamafutha), umoya (ongu-~78% we-nitrogen, ~21% we-oxygen) ungafakwa ekufinyezweni. I-oxygen isabela kakhulu futhi iholelaukuwohloka kwe-oxidativeLokhu kubangela ukunambitheka okungekuhle, iphunga elibi, kanye nokuwohloka kwekhwalithi. Kuphinde kumnyama umbala wesifinyezo.
• Isixazululo: Ukunciphisa i-nitrogen.Ngaphambi kokuba ukufinyezwa kupakishwe, igesi ye-nitrogen yezinga lokudla igeleza ngowoyela oshisayo owuketshezi. Le nqubo ibizwa ngokuthi "i-sparging."
  • Amabhamuza e-nitrogen akhipha umoya-mpilo oncibilikisiwe kanye nezinye izinto eziguquguqukayo ezibangela ukunambitheka okungekuhle.
  • Umphumela ubaukukhishwa komoyaumkhiqizo onokuqukethwe okuphansi kakhulu komoya-mpilo, okwandisa kakhulu isikhathi sawo sokuphelelwa yisikhathi.

2. Ukumboza (Ukuhlanza Nokuvikela)

I-nitrogen isetshenziselwa ukudala umoya ongasebenzi noma kuphi lapho umkhiqizo uvezwa khona emoyeni.

• Amathangi Okugcina Izinto:Amathangi amakhulu okugcina uketshezi oluqediwe ahlanzwa nge-nitrogen. Igesi, njengoba inzima kunomoya, ihlala phezu koketshezi, idale "ingubo" evikelayo evimbela umoya ukuthi ungathintani nobuso bomkhiqizo.
• Ukugcwalisa Nokupakisha:Ngesikhathi kugcwaliswa amabhavu, ama-cubes, noma ama-drum, i-nitrogen ivame ukufakwa endaweni engenalutho (isikhala esingenalutho phezulu kwesitsha) ngaphambi nje kokuba isivalo sivalwe. Lokhu kususa umoya ocebile nge-oxygen obekungabanjwa ngaphakathi kwephakeji, okuhlinzeka ngokuvikeleka kusukela ngesikhathi uvalwe ngaso.

3. Isakhiwo Esibonakalayo Nokusebenza Kahle

Nakuba kungewona umsebenzi wayo oyinhloko, i-nitrogen ingathonya ukuthungwa komkhiqizo wokugcina.

• Ukwakheka kwekristalu:Ukupholisa okusheshayo (ukubanda nokwenza ipulasitiki) kokufinyeza kuklanyelwe ukudala amakristalu amafutha azinzile anika ukufinyeza ukuthungwa kwawo okuqinile kodwa okugobekayo. Ukuba khona kwamabhamuza egesi angangeni kungathonya le nqubo yokwenza amakristalu.
• Amandla Okufaka Umoya Nokukhilimu:Kweminye imikhiqizo emfushane ekhethekile (ikakhulukazi leyo esetshenziselwa ukubhaka ukuze kwenziwe ukhilimu), amabhamuza amancane e-nitrogen afakiwe angasebenza njengezindawo zokwakheka kwe-nucleation. Lokhu kungathuthukisa ikhono lomkhiqizo lokubamba umoya uma ushaywa ushukela, okuholela ekuvuthweni nasekuthungeni okungcono ezintweni ezibhakiwe njengamakhekhe nama-icing. Lokhu kuwumphumela wesibili olawulwayo.

4. Ukuphepha

• I-nitrogen iyigesi engasebenzi. Ayisebenzi uma ifinyezwa, ayisekeli ukusha, futhi ayishi, okwenza kube ukukhetha okuphephile kokusetshenziswa endaweni yokucubungula ukudla.

Isifinyezo: Izinzuzo Eziyinhloko Zokusebenzisa i-Nitrogen

Lokho i-nitrogen engasetshenziselwa kona:

• AKUSIYONA into ephehla ugesi:Ngokungafani namathini kakhilimu ohlutshiwe (asebenzisa i-Nitrous Oxide, N₂O), i-nitrogen ayisetshenziswa "ukushaya" noma ukupholisa umoya ngendlela efanayo. Umphumela wayo womoya uyisici esicashile, esakhelwe ngaphakathi.
• AKUSIYO isithako:Kuyi-Usizo Lokucubungula Ibanga Lokudla(kuhlukaniswa njenge-GRAS - Ngokuvamile Kuqashelwa Njengokuphephile). Akubhaliwe esitatimendeni sesithako ngoba akuhlosiwe ukuthi kuhlale ekudleni ngobuningi obukhulu; kuyasetshenziswa bese kukhishwa umoya.

Ekuphetheni, i-nitrogen ibalulekile ekukhiqizweni kwesimanje kokunciphisa imfucuza. Iyithuluzi elihlanzekile, elingenamsebenzi, neliphumelelayo lokuqinisekisa ukuthi umkhiqizo ofinyelela kumthengi uzinzile, usezingeni eliphezulu, futhi uhlala isikhathi eside eshalofini ngokunciphisa ngamandla ukuchayeka ku-oxygen eyonakalisayo.
