Ngenxa yemvelo yayo ye-inert, i-nitrogen yaseGaseous ingasetshenziswa ekuhlanzeni okuhlukahlukene, ukumboza kanye nokusebenza okugcwele. Ngokuya ngohlobo lwenqubo ehilelekile, amazinga ahlukene wobumsulwa be-nitrogen ayadingeka ukuze ahlangabezane nezidingo ezihlukile zokukhiqiza.
Yini ubumsulwa be-nitrogen?
Ubumsulwa be-nitrogen ngamaphesenti ama-nitrogen akhona esampuli elithathwe emfuleni walo uma liqhathaniswa nokungcola okukhona. I-nitrogen ingahlukaniswa njengobumsulwa obuphakeme noma obuphansi ngokususelwa ku-ratip of the pure of pure gratinants okungcolile njenge-oksijini, umphunga wamanzi, i-carbon monoxide nekhabhoni diokside.
Lokhu kuhlukaniswa kususelwa ekuhluthelweni kwe-nitrogen kudlala indima ebalulekile ekunqumeni ukufaneleka kwe-nitrogen kunoma iyiphi inqubo yezimboni.
Ukuhlanzeka okuphezulu vs. Ukuhlanzeka okuphansi kwe-nitrogen
Ubumsulwa besampula le-nitrogen bunqunywa ngamaphesenti / ukugxila kwe-nitrogen emsulwa kuyo. Ukuze igesi ukuze ihlukaniswe njengomsulwa eliphezulu, kufanele iqukathe okungenani ama-99.998% nitrogen, kanti ama-nitrogen aphansi aphansi aqukethe amaphesenti aphezulu okungcola.
Ubumsulwa obuphezulu be-nitrogen
I-Gaseous nitrogen enokuhlushwa okungenhla nge-99.998% ibhekwa njengengxenyenashi ebuhlungu. I-nitrogen ebuhlungu ephezulu ingahle ibekwe ngezindlela ezihlukile ngabakhiqizi abahlukahlukene, kepha bathathwa kakhulu "izingxenyana" ze-zero grade ". I-nitrogen ye-zero-grade ebumsulwa ihlukaniswe ngayo izigaba ngenxa yokuthi iqukethe ukungcola kwe-hydrocarbon ezingaphansi kwezingxenye eziyi-0,5 ngesigidi.
Ezinye izici ezibalulekile ze-nitrogen ephezulu yokuhlanzeka yilezi:
Ukuhlushwa komoya-mpilo ≤ 0.5 ppm
I-Carbon Moxide / Carbon Dioxide hhayi engaphezu kwe-1.0 ppm
Umswakama ungakhulu kune-3 ppm
Ubumsulwa obuphansi be-nitrogen
I-nitrogen enobumsulwa bama-90% kuya ngaphansi kwama-99.9% abhekwa njengobumsulwa obuphansi.
Ukuhlukaniswa kobumsulwa be-nitrogen
Ukuhlukaniswa kwe-nitrogen emsulwa kwenziwa ngohlelo lokuhlela kusetshenziswa izinombolo ngaphakathi kwebanga ngalinye elihlanzekile eliphansi kakhulu. Inani lokuqala lebanga ngalinye libhekisela enanini "lamaNines" avela ngaphakathi kwalo, ngenkathi inombolo yesibili imelela inombolo ngemuva kwezinombolo eziyisishiyagalolunye zokugcina.
Amabanga amsulwa we-nitrogen ahlukaniswe njenge-N2.0, N3.0, N4.0, N5.0, N6.0, no-N7.0.
Yini i-nitrogen ebuhlungu ephakeme ye-Ultra-high?
I-nitrogen ye-Ultrahigh-purmity i-nitrogen inenqwaba yokungcola okungu-99.999% nokungathandeki. Ukucaciswa kwe-nitrogen kuqinile futhi kwehlukahlukana kuqinisa ukuhlukaniswa.
Igesi akumele iqukathe izingxenye ezingaphezu kwezimbili eziyisigidi ngevolumu (i-PPMV) ye-oksijini, izingxenye eziyi-0,5 ngevota I-nitrogen isetshenziselwa kakhulu izinhlelo zokusebenza zesayensi.
Yini i-nitrogen engenayo umoya-mpilo?
I-oksijini yamahhala ye-nitrogen (ofn) ichazwa njenge-gaseous nitrogen equkethe izingcezu ezi-0,5 ngesigidi (i-ppm) somoya-mpilo. Amagesi ka-Ofn ngokuvamile agcinwa ekuhlanzeni okungu-99.998%. Leli banga le-nitrogen lisetshenziselwa ukucwaninga kwesayensi kanye nezinqubo zokulinganisa lapho ukungcola kwe-oxygen kungaguqula imiphumela noma kubangele imiphumela engalungile.
Amazinga wokuhlanzeka we-nitrogen ngemboni / isicelo
Njengoba kushiwo ngenhla, ukugcwaliseka kwe-nitrogen okudingekayo ezinqubweni ezahlukahlukene zezimboni kuyahluka kakhulu. Ukucatshangelwa okusemqoka ekukhetheni ibanga le-nitrogen kuwumphumela wokungcola ohlelweni olukhethiwe. Uzwela oluya umswakama, umoya-mpilo kanye nabanye abangcoliso yizici ezibalulekile okufanele zicatshangelwe.
Ibanga le-Nitrogen / Beverage Ibanga Nitrogen
I-nitrogen isetshenziswa kakhulu ezinyathelweni ezahlukahlukene zokukhiqizwa kokudla / zokuphuza, ukupakishwa nokugcinwa. I-nitrogen ekuhlanganisweni kokudla nokucutshungulwa isetshenziselwa ukugcina impilo yeshalofu yokudla okucutshunguliwe / iziphuzo ngokususa ama-oxidants wokudla, ukulondolozwa ukunambitheka nokuvimbela ukubhebhetheka. Ubumsulwa obudingekayo be-Nitrogen yebanga lokudla buvame kakhulu ebangeni lama-98-99.5%.
Ibanga le-nitrogen le-Pharmaceutical
Izinqubo zokukhiqiza amakhemikhali zidinga ubumsulwa obuphezulu bokuvimbela ukungcoliswa kanye nokuguqulwa komkhiqizo wokugcina. Ama-Pharmaceuticals amaningi adinga i-Nitrogen ephezulu yebanga enobufebe phakathi kuka-97-99.99%. Lokhu kuphakama ku-nitrogen purnity-high-high
I-Nitrogen Ebuhlungu Ephakeme futhi isetshenziswa emaphaketheni emithi okusiza ukugcina okusha nokuvimbela ukonakala kwezithako ezisebenzayo.
I-Gaseous nitrogen enobumsulwa abangama-95-99% isetshenziswa embonini kawoyela negesi ukunciphisa ubungozi bomlilo nokuqhuma ngesikhathi senqubo. Ukufaka amathangi okugcina amakhemikhali namapayipi okuhlanza nge-gaseous nitrogen kusiza ukunciphisa ingozi yokuhlangana okungazelelwe kokuqukethwe kwabo.
Izinsizakalo zokulungiswa kwepayipi zivame ukusebenzisa i-nitrogen ecindezelwe yokuhlanza amapayipi kanye nezinqubo zokuqothula amapayipi.
Ubumsulwa ebangeni le-nitrogen ye-nitrogen yezimboni
Ezinye izinhlelo zezimboni kanye nezidingo zabo zebanga le-nitrogen zichazwe ngezansi.
I-Electronics ne-semiconductor yokukhiqiza i-nitrogen
Izidingo ezijwayelekile zokuqukethwe ze-nitrogen kuma-elekthronikhi kanye nokukhiqizwa kwe-semiconductor kuvame okungenani 99.99-99.999%. Ezinye izinqubo ezinjengezingxenye zokuhlanza kanye nokumboza okunamathelayo zisebenzisa ukugxila okuphansi kwe-nitrogen (95-99.5%).
I-Plastics Production Gradeninininini Nitrogen
Izidingo ze-Nitrogen Ibanga le-plastics synthesis zingama-95-98% zokubumba umjovo, 99,5% zokubumba komjovo osiza igesi, kanye nama-98-99.5% ukukhishwa kwefilimu okushayayo.
I-Metal Processing Ibanga Nitrogen
Ukuqukethwe kwe-nitrogen kwebanga lensimbi kuhluka kakhulu, kusuka kuma-95-99% kokwelashwa okushisa ku-99-99.999% yenqubo yokusika ye-laser.
Ibanga Lokuphelelwa amandla Ibanga le-Nitrogen
I-Nitrogen ebangeni lama-95-99.6% liyadingeka ezinqubweni zokuphehla amandla ezifana ne-Air Seal Blowdown, i-boiler lining, i-pipeline yemvelo yepasipi i-blowdown kanye nokuthambisa amanzi.
