Kwindawo yokwenziwa kwezinto eziphambili, isinyithi, kunye nophando lwezenzululwazi, ukukhetha igesi ye-cryogenic yeyona nto ibalulekileyo kubunjineli kunye nesigqibo sezemali. Xa abaphathi bezibonelelo kunye namaqela okuthenga evavanya ulwelo argon vs ulwelo nitrogen, bahlala benyanzeliswa ukuba balinganise amandla okupholisa ngokugqithisileyo ngokuchasene nozinzo olupheleleyo lweekhemikhali kunye neendleko zokusebenza ngokubanzi.

Ngelixa zombini iigesi zingenambala, azinavumba, kwaye azinatyhefu kwiindawo zazo ezicocekileyo, iipropathi zazo ezahlukeneyo zomzimba kunye neekhemikhali ziyalela usetyenziso lwamashishini olwahlukileyo. Esi sikhokelo siya kunika uthelekiso olubanzi ukukunceda ukuba ubone ukuba yeyiphi irhasi ye-cryogenic efanelekileyo kwiimfuno zakho zeprojekthi.

Umahluko ongundoqo: iiPropati zoMzimba kunye neeKhemikhali Ukungalali

Ukwenza isigqibo esinolwazi, kubalulekile ukuqonda umahluko osisiseko phakathi kwezi zimbini ze-cryogenic liquids kwinqanaba le-molecular:

Iqondo lobushushu kunye nendawo yokuBilisa: Ulwelo lwenitrogen (LN2) lubanda kancinci, luneqondo lokubila elingu -196°C (-320°F). I-Cryogenic liquid argon (LAr) inendawo yokubila eshushu kancinane -186°C (-303°F). Ukuba ekrwada, ukupholisa kobushushu obuphantsi kakhulu kuphela kwemfuneko yakho, initrogen ibamba isiphelo sethermal esincinci.

Uzinzo kwiMichiza (IsiGqibo sokuGqibela): I-Nitrogen yigesi ye-diatomic (N2) esebenza njengegesi engasebenziyo kwiqondo lobushushu begumbi. Noko ke, phantsi kobushushu obugqithiseleyo—njengakwi-welding arc okanye kwiziko elinobushushu obuphakamileyo—initrogen inokusebenza ngeentsimbi ukuze yenze i-nitrides e brittle. IArgon, kwelinye icala, igesi ehloniphekileyo. I-monoatomic ngokupheleleyo kwaye iqhayisa i-100% inertness yeekhemikhali kuwo nawuphi na ubushushu. Ayinakuze isabele, i-oxidize, okanye iguqule imathiriyeli eyikhuselayo.

Ubuninzi: Irhasi yeArgon imalunga nama-38% ubunzima kunomoya, ukuyivumela ukuba idibane ngokufanelekileyo phezu kwezinto zokusebenza kwaye ibonelele ngengubo yokukhusela egqwesileyo. I-nitrogen ikhaphukhaphu kancinane kunomoya, okuthetha ukuba ichitheka ngokukhawuleza kwindawo evulekileyo.

Ukuphonononga Ukusetyenziswa kweArgon ye-Industrial Liquid: Ibaluleke nini iArgon?

Kuba iargon yenza kuphela malunga ne-0.93% yeatmosfera yoMhlaba (xa kuthelekiswa ne-nitrogen ye-78%), kubiza kakhulu ukuvelisa nge-fractional distillation. Ngoko ke, i-argon yolwelo lwamashishini usetyenziso lugcinelwe usetyenziso apho ukunganyaniseki kwekhemikhali ngokupheleleyo kungaxoxiswana.

izicelo eziphambili ezithembele cryogenic liquid argon ziquka:
I-Arc Welding (TIG kunye ne-MIG): IArgon ngumgangatho wegolide wokukhusela iigesi kwiwelding, ngakumbi kwiintsimbi ezisebenzayo ezifana ne-aluminiyam, i-titanium, kunye nentsimbi engenasici. Ubuninzi bayo obuphezulu bubonelela ngekhuselo eliphezulu ngokuchasene neoksijini ye-atmospheri, ngelixa ukungazenzisi kwayo kuthintela i-weld porosity kunye ne-brittleness, iqinisekisa isandi esakhiweyo kunye nedibeneyo ecocekileyo ngobuhle.

IMveliso yeNsimbi ekwinqanaba eliphezulu kunye neNtsimbi: Kwinkqubo ye-AOD (iArgon Oxygen Decarburization) esetyenziselwa ukuvelisa isinyithi esingenasici, i-argon yolwelo ifakwe umphunga kwaye ivuthelwe kwisinyithi esinyibilikisiweyo. Inceda ukususa ikhabhoni kunye nobunye ukungcola ngaphandle kwe-oxidizing umxholo oxabisekileyo wechromium.

ISemiconductor kunye nokuveliswa koMbane: Njengoko kuxoxiwe kwizikhokelo zethu zangaphambili, ukukhula kweekristale zesilicon ezingenasiphako kufuna indawo engena-oksijini ngokupheleleyo kwaye ingasebenziyo. I-argon yolwelo ibonelela ngesi sikhuselo se-atmospheric esicocekileyo, sithintela iziphene ezincinci ezinokonakalisa i-nano-scale microchips.

Ummandla weNitrojeni engamanzi: Yeyiphi iNitrogen lolonaKhetho oluLungcono?

Ukuba iprojekthi yakho ayibandakanyi ubushushu obugqithisileyo okanye iintsimbi ezisebenzayo, initrogen engamanzi isoloko ilolona khetho lungabizi kakhulu. Usetyenziso lwayo oluphambili lwemizi-mveliso luxhomekeke kumandla ayo okukhenkceza ngokukhawuleza kunye neempawu ezisisiseko zokucoca:

Umkhenkce weCryogenic kunye nokuLungiswa kokutya: I-LN2 isetyenziswa ngokubanzi kwi-Individual Quick Freezing (IQF) yeemveliso zokutya, ukuvalela ukufuma kunye nokuthembeka kweselula ngaphandle kokuguqula ukutya ngokwekhemikhali.

UkuFaniswa kweSrink: Kubunjineli bomatshini, initrogen engamanzi isetyenziselwa ukucutha amacandelo esinyithi (njengeebheringi okanye iishafti) ukuze zifakwe lula kwiindawo zokukhwelana. Njengoko intsimbi ifudumala, iyanda, idala uphazamiseko oluqinileyo ngokumangalisayo.

Ukucoca ngokuBanzi kunye nokunxiba: Ukutyhala ulwelo oluguquguqukayo ngemibhobho okanye ukugquma iitanki zokugcina imichiza ukuze kuthintelwe ukutsha, initrogen ibonelela ngokusingqongileyo okwaneleyo kwe-inert kwiqhezu leendleko ze-argon.

Isigwebo: Unokukhetha njani?

Xa uthatha isigqibo phakathi kwe-argon yolwelo vs initrogen engamanzi, umthetho wesithupha uthe ngqo:

Khetha I-nitrogen yolwelo ukwenzela ukupholisa kwe-cryogenic okucocekileyo, okungabizi kakhulu, ukukhenkceza kokutya, kunye nokufuduswa kwe-oksijini esisiseko apho ubushushu obugqithisileyo abuyiyo into.

Khetha I-argon engamanzi xa inkqubo yakho ibandakanya ii-arcs zombane, isinyithi esinyibilikisiweyo, okanye izinto zombane ezibuthathaka kakhulu apho kufuneka ukunganyaniseki kweekhemikhali ukunqanda ukuthotywa kwezinto.
