Kungani i-nitrogen ewuketshezi isetshenziswa kuma-crimal?
1. Kungani usebenzise i-nitrogen ewuketshezi njengesiqandisi?
1. Ngoba amazinga okushisa we I-liquid nitrogen ngokwayo iphansi kakhulu, kepha imvelo yayo imnene kakhulu, futhi kunzima ukuthi i-nitrogen ewuketshezi icubungulwe amakhemikhali, ngakho-ke ivame ukusetshenziswa njengeqandisini.
2. I-liquid nitrogen I-Vaporizes ukumunca ukushisa, yehlise izinga lokushisa, futhi ingasetshenziswa njengesiqandisi.
3. Ngokuvamile, i-ammonia isetshenziswa njenge-esiqandisini namanzi njengokumunca.
I-4. Igesi ye-ammonia iphoqelekile yi-condenser ukuze ibe yi-ammonia ye-liquid, bese i-ammonia ingena ku-evaporator ukuthi ihaqe, futhi ngasikhathi sinye ithola ukushisa ngaphandle ukuze ifinyelele umjikelezo wokuqapha.
I-5. I-nitrogen ingasetshenziswa njengesiqandisi esigabeni "esingu", eduze kwe-degrees ephelele (-273.15 degrees Celsius), futhi ngokuvamile isetshenziswa ezindaweni zokufunda ukuze ifunde ama-supercomputicicies.
I-6. Kwezokwelapha, i-nitrogen ewuketshezi ivame ukusetshenziswa njengesiqandisi sokwenza imisebenzi ngaphansi kwe-crsoanesthesia.
7. In the high-tech field, i-nitrogen ewuketshezi ivame ukusetshenziselwa ukudala imvelo yokushisa ephansi. Isibonelo, ezinye izinto ezinhle kakhulu zithola kuphela izakhiwo ezinhle kakhulu kumazinga okushisa aphansi ngemuva kokuphathwa nge-nitrogen ewuketshezi.
8 Ukuchithwa okushisa okuphansi kwamathayi, ukugcinwa kweGene ezibhedlela, njll. Zonke zisebenzisa i-nitrogen ewuketshezi njengomthombo obandayo.
2. I-litrogen ewuketshezi igcina kanjani amangqamuzana?
Indlela esetshenziswa kakhulu yokulondolozwa kweseli iyindlela yokulondolozwa kwe-nitrogen ye-nitrogen, eyisamukelayo ikakhulukazi indlela ehamba kancane enesilinganiso esifanelekile se-ejenti evikelayo yokuqamba amaseli.
QAPHELA: Uma amaseli aqandiswe ngokuqondile ngaphandle kokungeza noma yimuphi umenzeli wokuvikela, amanzi ngaphakathi nangaphandle kwamaseli azokwakha amakristalu eqhwa ngokushesha, okuzobangela uchungechunge lokuphendula olubi. Isibonelo, ukuphelelwa amandla kwamaseli kwandisa ukugxila kwe-electrolyte yendawo, kuguqula inani le-PH, kanye namaprotheni athile ngenxa yezizathu ezingenhla, okwenza ukwakheka kwendawo yangaphakathi kukhishwe. Ibangela ukulimala, ukuvuvukala kwe-mitochondrial, ukulahleka kokusebenza, kanye nokuphazamiseka kwe-mandla yemetabolism. I-Lipoprotein Complex ku-membrane yeseli nayo ibhujiswe kalula, ibangele izinguquko ekulweni kwe-membrane yeseli nokulahleka kokuqukethwe kweseli. Uma kwakhiwa amakristalu eqhwa amaningi kumaseli, njengoba izinga lokushisa leqhwa liyancipha, umthamo wamakristalu eqhwa uzokwandisa, okuholela ekulimaleni okungenakuphikiswa ekucushweni kwendawo ye-DNA yenuzi, okuholela ekufeni kweselula kwe-DNA yenuzi, okuholela ekufeni kweseli.
Ukushisa okushisayo nokunengqondo kudonswa ukudla kwe-nitrogen ewuketshezi ekuxhumaneni nokudla kubangela ukudla kukhululeke. I-liquid nitrogen ikhishwe esitsheni, ngokuzumayo ishintsha ekushiseni okujwayelekile kanye nengcindezi, futhi iguqulwe kusuka ku-liquid ibe yi-Gaseous State. Ngesikhathi senqubo yokushintsha kwesigaba, i-nitrogen ye-nitrogen ewuketshezi futhi ivele ku-at -195.8 ℃ ukuze ibe yi-nitrogen yase-gaseous, kanye nokushisa kwamuva kokuhwamuka kungu-199 / kg; Uma -195.8 Lapho amazinga okushisa ekhuphuka abe-20 ° C ngaphansi kwe-nitrogen ekucindezelweni komkhathi, kungadonsa i-183.89 KJ / kg Ukushisa kungafinyelela ku-383 kj / kg.
Esezinhlelweni zokudla kokudla, ngoba inani elikhulu lokushisa lithathwa ngokushesha, izinga lokushisa lokudla lipholile ngokushesha kusuka ngaphandle kuya ngaphakathi kuya ngaphakathi ku-free. Ubuchwepheshe be-Liquid Nitrogen-FreeZing Technology busebenzisa ubuchwepheshe be-liquid nitrogen njengomthombo obandayo, ongalimazi imvelo. Uma kuqhathaniswa nesiqandisi semishini yendabuko, kungafinyelela izinga lokushisa eliphansi kanye nezinga eliphakeme lokupholisa. Ubuchwepheshe be-Litrogen Quit-Free-FreeZing Technology bunesivinini esikhulu sokuqabula, isikhathi esifushane, futhi ukudla kungokwekhwalithi enhle, ukuphepha okuphezulu nokungcola.
Ubuchwepheshe be-Liquid Nitrogen Suck-FreeZing Technology busetshenziswe kabanzi ekugcizelweni okusheshayo kwemikhiqizo yasemanzini efana ne-shrimp, whitebait, crab yemvelo, ne-abalone. Ucwaningo lukhombisile ukuthi i-shrimp ephathwe ubuchwepheshe be-litrogen i-Quick-FreeZing Technology ingagcina okusha, umbala nokunambitha. Hhayi lokho kuphela, amanye amagciwane angabulawa noma ayeke ukuzala kabusha emazingeni okushisa aphansi ukuze afeze indle ephakeme.
Ukulondolozwa kwe-Cropresses: I-nitrogen ewuketshezi ingasetshenziselwa ukulondolozwa kwamasampula ahlukahlukene okuzalwa, njengamaseli, izicubu, i-serum, isidoda, njll. Lawa amasampula angagcinwa isikhathi eside emazingeni okushisa aphansi futhi abuyiselwe esimweni sawo sokuqala lapho kudingeka. Ukulondolozwa kwe-nitrogen i-nitrogen kuyindlela yokugcina esetshenziswa kakhulu, evame ukusetshenziswa ocwaningweni lwe-biomedical, ezolimo, ekulimaleni kwezilwane kanye nezinye izinkambu.
Isiko leseli: I-nitrogen ewuketshezi nayo ingasetshenziselwa isiko leseli. Ngesikhathi sesiko leseli, i-nitrogen ewuketshezi ingasetshenziswa ukugcina amaseli emisebenzi yokuhlola elandelayo. I-nitrogen ewuketshezi nayo ingasetshenziswa ukukhulula amaseli ukuze ilondoloze ukusebenza kwayo kanye nezakhiwo zebhayoloji.
Isitoreji Seseli: Ukushisa okuphansi kwe-nitrogen ewuketshezi kungagcina ukuqina nobuqotho bamaseli, ngenkathi kuvimbela ukuguga kweseli nokufa. Ngakho-ke, i-nitrogen ewuketshezi isetshenziswa kabanzi kwisitoreji seseli. Amaseli agcinwe ku-nitrogen awuketshezi angatholwa ngokushesha lapho kudingeka futhi asetshenziselwe amandla ahlukahlukene okuhlola.
Ukusetshenziswa kwe-nitrogen ye-Food-gradeniquid Nitrogen kufana ne-nitrogen ye-nitrogen ye-nitrogen, amabhisikidi e-nitrogen awuketshezi, i-nitrogen ye-nitrogen eqandayo kanye ne-anesthesia kwezokwelapha nayo idinga i-nitrogen evuna ngayo. Ezinye izimboni ezinjengemboni yamakhemikhali, i-elekthronikhi, i-metallurgy, njll. Yiba nezidingo ezihlukile zobumsulwa be-nitrogen ewuketshezi.
