Nitrogen lokushisa liquid

liquid nitrogen sisetshenziselwa izinto okusobala ukuminyana kabani lolutsite 0,808 g / cm³. Lokhu - omunye isimo wokuhlanganisa lapho kungaba i-nitrogen, izinga lokushisa elenza -195,75 C. Liquid nitrogen akuyona ezinobuthi futhi ukuqhuma-ubufakazi.

Isici esivelele sesimiso ukusebenza futhi isitoreji liquid nitrogen wukuthi uma evuthayo, ke yandisa kakhulu, isibonelo, izinga lokushisa ophakamayo kuphela 20 C, kwakhiwa ilitha nto mayelana 700 amalitha igesi. Ngakho-ke, isitoreji kanye zokuhamba zeziqukathi yayo ekhethekile zisetshenziswa, okubizwa ngokuthi izitsha Dewar ezihlinzeka cleaner atihambi todvwa.

liquid nitrogen is atholakele kabanzi ngempela esetshenziswa emikhakheni ehlukahlukene umsebenzi womuntu, ngezindlela eziningi, i-ububanzi ezifana ukusetshenziswa ngenxa yalokhu impahla, izinga lokushisa kwe-liquid nitrogen. It is lisetshenziswe izimboni lapho kuyadingeka ukusetshenziswa kobuchwepheshe cryogenic ukusika izinto ezimbiwa phansi. A kakhulu lokushisa ongaphakeme of liquid nitrogen evumela ukusetshenziswa kwayo okujulile-eqandisiwe, futhi kulo mkhakha ke kufanelekile kokubili izinto wezinto ezingaphili futhi organic, kuhlanganise izinto eziphilayo.

Kukhona ezinye izinhlelo zokusebenza zifaka: ukucima umlilo futhi iyapholisa amayunithi ahlukahlukene kanye namadivayisi lobuchwepheshe, cryopreservation lamaseli Overclocking.

At umfutho womoya, liquid nitrogen lokushisa ngezansi lokushisa ukufingqa umoya-mpilo ebangeni degrees 10 Nokho, njengoba umthetho, ezindongeni umkhumbi waphawula condensate izidakamizwa kwenze.

Ngenxa yokuthi le abilayo nitrogen ungaphakathi isimo uketshezi - 195,8 C, okuyinto leliphasi kunaleyo oxygen uketshezi lapho okuhlala kuba - 183 C, umphumela ekusebenzelaneni kwabo emoyeni ketshezi ahlanganiswe umoya-mpilo ngokushesha okukhulu. Lokhu kuchaza umehluko okushisa kanye bazolokhu ukuhwamuka of liquid nitrogen, uma iqhathaniswa naso -mpilo ketshezi.

Cishe noma yimuphi lokushisa ukuthi idlula inkomba liquid nitrogen, kungabonakala nasemkhakheni lapho siqhuba ukuhlola elandelayo. Ibalulekile le block aluminium ukuthi selehlile, uma kancane kancane iconsa emoyeni ketshezi.

Kwezobuchwepheshe banamuhla izinga lokushisa liquid nitrogen njengoba impahla eziyisisekelo izinto okubangelwa ukusetshenziswa kabanzi ezimbonini electronic kagesi futhi Semiconductors, okuyinto ngaleyo ndlela athole indlu okuthembekile.

On isimiso esifanayo, nezinhlelo zokusebenza izidakamizwa based njengoba ingxenye umlilo Izingxube ahlukahlukene. Ngo inqubo zokucisha nitrogen iyasha ngokushesha okukhulu, futhi kanjalo, displaces oksijini, kuphumele ukuqedwa kokufinyelela oxygen umlilo umlilo umlilo itholakala futhi eyeka ngokuphelele. Ngenxa lo mphumela namuhla nitrogen nemililo uthathwa kuphumelela ngaphezu kwe-carbon-dioxide. Uma usebenzisa ubuchwepheshe obufana, ngezinga eliphezulu ukulondolozwa yengcebo.

Ngokuvamile, umphumela liquid nitrogen unekhono ukuqapha cishe njalo, uma alinake yayo kokunikela movie-like, elisetshenziswa ukuthwetshulwa amafilimu wesimanje. Ngokwesibonelo, e-movie 'The Terminator' imiphumela ezisetshenziswa kakhulu atholakala ngokusebenzisa liquid nitrogen (ozimele, ebonisa osheshayo okokuqandisa izindawo). Kodwa lo mphumela kungaba okuningi incarnation umkhuba. Ngokwesibonelo, ongaphakeme lokushisa nitrogen evumela ukusebenzisa kwayo i-frost okusheshayo analgesic uhlamvu. Lokhu ngokuvamile singakwazi ukugcina phakathi umcimbi wezemidlalo, lapho umsubathi liyagula, nayo yonke nosizo lwakhe lokuqala ngokusebenzisa wendawo aerosol izinzwa.

Okuningi ezingavamile, uma kungekhona kumnandi, manje simi ukusetshenziswa ketshezi njengendlela yokuthola okokuqandisa eziphilayo, enombono defrosting yabo okwalandela, nokulondoloza izakhiwo begazi.

Ngesikhathi esifanayo, kokubili e-US kanye eRussia, zikhona kakade izinkampani ukuthi kukhona okudayiswayo ahileleke okokuqandisa cryogenic nezilwane.
