I-nitrogen ewuketshezi iwumthombo obandayo olula. Ngenxa yezici zayo eziyingqayizivele, i-nitrogen eyi-liquid iye yathola ukunakwa nokuqashelwa kancane kancane, futhi iye yasetshenziswa kabanzi ekufuyweni kwezilwane, ekunakekelweni kwezokwelapha, embonini yokudla, nasezinkundleni zokucwaninga ngezinga lokushisa eliphansi. , kwezobuchwepheshe, i-metallurgy, i-aerospace, ukukhiqizwa kwemishini nezinye izici zokwanda nokuthuthukiswa okuqhubekayo.
I-nitrogen eyi-Liquid okwamanje iyi-cryogen esetshenziswa kakhulu ku-cryosurgery. Ingesinye seziqandisi ezingcono kakhulu ezitholakala kuze kube manje. Ingajovwa emshinini wezokwelapha we-cryogenic, njenge-scalpel, futhi ingenza noma yikuphi ukuhlinzwa. I-Cryotherapy iyindlela yokwelapha lapho izinga lokushisa eliphansi lisetshenziselwa ukubhubhisa izicubu ezigulayo. Ngenxa yokushintsha okubukhali kwezinga lokushisa, amakristalu akhiwa ngaphakathi nangaphandle kwezicubu, okubangela ukuba amangqamuzana aphelelwe amanzi emzimbeni futhi ashwabane, okuholela ekushintsheni kwama-electrolyte, njll. Ukubanda kunganciphisa nokugeleza kwegazi lendawo, futhi i-microvascular stasis noma i-embolism ibangela ukuba amangqamuzana afe ngenxa ye-hypoxia.
Phakathi kwezindlela eziningi zokulondoloza, i-cryopreservation iyona esetshenziswa kakhulu futhi umphumela ubaluleke kakhulu. Njengenye yezindlela ze-cryopreservation, i-nitrogen ewuketshezi yokuqandisa isikhathi eside yamukelwa amabhizinisi okucubungula ukudla. Ngenxa yokuthi ikwazi ukuqandisa ngokushesha kakhulu izinga lokushisa eliphansi kanye neqhwa elijulile, iphinde ikhuthaze ukuqiniswa kwengxenye kokudla okuqandisiwe, ukuze ukudla kululame kakhulu ngemva kokuncibilika. Esimeni sokuqala esisha kanye nemisoco yokuqala, izinga lokudla okufriziwe liye lathuthukiswa kakhulu, ngakho-ke kubonise ubungqabavu obuyingqayizivele embonini yokuqandisa okusheshayo.
Ukunciphisa izinga lokushisa eliphansi lokudla ubuchwepheshe obusha bokucubungula ukudla obuthuthukiswe eminyakeni yamuva nje. Lobu buchwepheshe bufaneleka ngokukhethekile ukucubungula ukudla okunezindleko eziphakeme ezinamakha, okuqukethwe kwamafutha amaningi, ushukela ophakeme kanye nezinto eziphezulu ze-colloidal. Ukusebenzisa i-nitrogen ewuketshezi ekushiseni okuphansi kwezinga lokushisa, ithambo, isikhumba, inyama, igobolondo, njll. yezinto ezingavuthiwe zingagaywa ngesikhathi esisodwa, ukuze izinhlayiya zomkhiqizo oqediwe zihle futhi zivikele umsoco wawo osebenzayo. Isibonelo, eJapan, izimila zasolwandle, i-chitin, imifino, izinongo, njll., ezifakwe iqhwa ku-nitrogen ewuketshezi, zifakwa ku-pulverizer ukuze zigaywe, ukuze usayizi wezinhlayiyana ezinhle zomkhiqizo oqediwe ufinyelele ku-100um noma ngaphansi, futhi inani lokuqala lokudla okunomsoco ligcinwe ngokuyisisekelo.
