Okokuqala, uhlobo lwe-nitrogen

I-nitrogen, ngaphansi kwezimo ezijwayelekile, iyigesi engenambala, engenakunambitheka, engenaphunga futhi ngokuvamile ayinabo ubuthi.I-nitrogen ibalelwa ku-78.12% wengqikithi yomkhathi (ingxenye yevolumu).Ezingeni lokushisa elivamile, igesi.Ngomfutho womoya ojwayelekile, uba uketshezi olungenambala uma upholiswe ku- -195.8℃.Uma ipholiswe ku- -209.86 ℃, i-nitrogen eyiketshezi iba into efana neqhwa.Ukusetshenziswa: ukuhlanganiswa kwamakhemikhali (inayiloni yokwenziwa, i-acrylic fiber, i-resin yokwenziwa, irabha yokwenziwa nezinye izinto ezibalulekile zokusetshenziswa), amathayi ezimoto (i-nitrogen inganciphisa ngempumelelo umsindo wamathayi, yelule impilo yesevisi yamathayi).Ngenxa yokuthi i-nitrogen ayisebenzi ngamakhemikhali, ivame ukusetshenziswa njengegesi evikelayo, njengekhabe, isithelo, ukudla, negesi yokugcwalisa izibani.

Okwesibili, ukusetshenziswa kwe-nitrogen

I-nitrogen ku-metallurgy, embonini yamakhemikhali, embonini ekhanyayo, e-electronics neminye iminyango, njengegesi yokudla, igesi evikelayo, igesi eshintshwayo kanye negesi yokuvala.Imikhiqizo ye-nitrogen ewuketshezi ibuye isetshenziswe kakhulu ekudleni okuqandisiwe, imifino kanye nokugcinwa kwezithelo.Ibuye isetshenziswe kabanzi kwezolimo kanye nokufuywa kwezilwane, njengokugcina okusanhlamvu okubulala izinambuzane, isitoreji esiqandisiwe sesidoda semfuyo ephakeme, njll. Ingabe iyingxenye yamaprotheni ezitshalweni nasezilwaneni.

Ngokuthuthuka kwesayensi nobuchwepheshe kanye nokuthuthukiswa komnotho, ububanzi bokusetshenziswa kwe-nitrogen buyanda usuku nosuku.

Sebenzisa ngokunenzuzo inertia ye-nitrogen

Ukucutshungulwa kwe-Metal okushisayo: ukucisha okukhanyayo, ukuthungatha okukhanyayo, ukungcwatshwa kwe-carburizing, i-carbonitriding, i-nitriding ethambile kanye nokunye ukwelashwa kwe-nitrogen okusekelwe emkhathini wokushisa womthombo we-nitrogen, i-welding kanye ne-powder metallurgy evuthayo inqubo yokuvikela igesi, njll.

Imboni ye-Metallurgical: ukusakaza okuqhubekayo, ukugingqika okuqhubekayo, umoya ovikelayo ohlanganisa insimbi, i-BOF top compound efutha i-nitrogen steelmaking, i-steelmaking BOF seal, uphawu lwe-BF phezulu, i-BF yokwenza insimbi umjovo wamalahle ophihliziwe nezinye izinqubo.

Ukusebenzisa i-cryogenic liquid nitrogen

Imboni ye-elekthronikhi: isekethe enkulu ehlanganisiwe, ishubhu yezithombe ze-TV enemibala, i-TV kanye nezingxenye zokuqopha kanye nokuvikelwa kwenqubo yokukhiqiza umqhubi, njll.

Ukulondolozwa kokudla: ukudla, isithelo (izithelo), imifino kanye nokunye ukugcina nokugcinwa kwesimo somoya, inyama, ushizi, isinaphi, itiye nekhofi, njengokupakishwa okusha, ujamu, njengokugcinwa kwe-nitrogen oxygenation, amabhodlela ahlukahlukene okuhlanzwa kwewayini nokumboza, njll.

Imboni yezemithi: Imithi yaseShayina (ginseng) i-nitrogen yokugcwalisa isitoreji kanye nokulondolozwa, ukugcwaliswa komjovo we-nitrogen wemithi yasentshonalanga, ithangi lokugcina kanye ne-container nitrogen egcwalisa umoya-mpilo, ukuhanjiswa kwezidakamizwa zomoya womthombo womoya, njll.

Imboni yamakhemikhali: ukushintshwa, ukuhlanza, ukuvala, ukutholwa kokuvuza nokuvikelwa kwegesi, ukucisha okomile, ukuvuselelwa kabusha kwe-catalyst, ukuhlukaniswa kwe-petroleum, ukukhiqizwa kwamakhemikhali amakhemikhali, njll.

Imboni kamanyolo: impahla eluhlaza yomanyolo we-nitrogen.Ikhophi yokuvikela i-Catalyst, igesi yokuwasha, njll.

Imboni yePlastiki: ukudluliswa kwe-pneumatic kwezinhlayiya zepulasitiki, ukukhiqizwa kwepulasitiki nokuvimbela i-oxidation yokugcina.

Imboni yenjoloba: ukupakishwa nokugcinwa kwerabha, ukukhiqizwa kwamasondo, njll.

Imboni yengilazi: Igesi evikelayo yenqubo yokukhiqiza ingilazi entantayo.

Imboni ye-Petroleum: ukugcwaliswa kwe-nitrogen nokuhlanzwa kwendawo yokugcina, iziqukathi, imibhoshongo ekhuthazayo namapayipi, ukutholwa kokuvuza kwengcindezi kwezinhlelo zokuphatha, njll.

Ukuthuthukiswa kukawoyela ogwini lolwandle: ukumbozwa kwegesi kwamapulatifomu kawoyela aphesheya kwezilwandle, umjovo we-nitrogen wokubuyisa uwoyela, ithangi lokucwilisa izitsha, njll.

Ukugcinwa kwezigaxa: ukuvikela indawo engaphansi komhlaba, inqolobane nokunye ukuthungela uthuli oluvuthayo kanye nokuqhuma, njll.

Ukuthumela: igesi yokuhlanza ithangi likawoyela, njll.

Ubuchwepheshe be-Aerospace: i-rocket fuel booster, qalisa igesi yokubuyisela iphedi kanye negesi yokuvikela ukuphepha, igesi yokulawula usomajukujuku, igumbi lokulingisa emkhathini, igesi yokuhlanza ipayipi likaphethiloli lendiza, njll.

Okunye: upende nokugcoba i-nitrogen oxygenation ukuvimbela i-polymerization yokomisa uwoyela, amathangi okugcina uwoyela negesi yemvelo neziqukathi ze-nitrogen oxygenation, njll.

Ukusebenzisa i-cryogenic liquid nitrogen

Umuthi we-Hypothermia: i-hypothermia yokuhlinzwa, i-cryotherapy, isiqandisi segazi, ukuqandisa izidakamizwa kanye ne-cryopatter, njll.

I-Biomedicine: i-cryopreservation kanye nokuthuthwa kwezitshalo eziyigugu, amaseli ezitshalo, i-germplasm yofuzo, njll.
