kuyilapho zombili i-Nickel 200 ne-Nickel 201 ziyi-alloy ze-nickel ezimsulwa, i-Nickel 201 inokumelana okungcono nokunciphisa izindawo ngenxa yokuqukethwe kwayo okuphansi kwekhabhoni. Ukukhetha phakathi kwalokhu okubili kuzoncika ezidingweni ezithile zohlelo lokusebenza kanye nendawo lapho izinto ezizosetshenziswa khona.
I-Nickel 200 kanye ne-Nickel 201 zombili ziyi-alloy ze-nickel ezihlanzekile ezithengiswayo ezihluka kancane ekwakhekeni kwazo kwamakhemikhali.
I-Nickel 200 iyi-ferromagnetic, emsulwa ngokwezentengiselwano (99.6%) i-nickel alloy enezakhiwo ezinhle zemishini kanye nokumelana okuhle kakhulu nezindawo eziningi ezigqwalisayo, kufaka phakathi ama-acid, ama-alkaline, kanye nezixazululo ezingathathi hlangothi. Inokumelana okuphansi kukagesi, okwenza ifaneleke ukusetshenziswa kukagesi kanye nogesi.
Ngakolunye uhlangothi, i-Nickel 201 nayo iyi-alloy ye-nickel emsulwa (99.6%) kodwa inokuqukethwe okuphansi kwekhabhoni uma kuqhathaniswa ne-Nickel 200. Lokhu okuqukethwe okuphansi kwekhabhoni kunikeza i-Nickel 201 ukumelana kangcono nokugqwala ezindaweni ezinciphisayo, njenge-sulfuric acid. Isetshenziswa kakhulu nasekucutshungulweni kwamakhemikhali, izingxenye ze-elekthronikhi, kanye namabhethri ashajwayo.
Ngamafuphi, yize zombili i-Nickel 200 ne-Nickel 201 ziyi-alloy ze-nickel ezimsulwa, i-Nickel 201 inokumelana okungcono nokunciphisa izindawo ngenxa yokuqukethwe kwayo okuphansi kwekhabhoni. Ukukhetha phakathi kwalokhu okubili kuzoncika ezidingweni ezithile zokusetshenziswa kanye nendawo lapho izinto ezizosetshenziswa khona.
I-Nickel200 iyi-alloy ye-nickel eyenziwe ngokuhweba emsulwa equkethe i-nickel engu-99.6%. Yaziwa ngokumelana kwayo nokugqwala okuhle kakhulu, ukuhanjiswa okuphezulu kokushisa kanye nogesi, okuqukethwe okuphansi kwegesi, kanye nezakhiwo ezinhle zemishini. Ingakhiwa kalula futhi inezinga eliphansi lokuhamba, okwenza ifaneleke ezinhlotsheni eziningi zezicelo okuhlanganisa ukucubungula amakhemikhali, izingxenye zikagesi, kanye nezindawo zasolwandle. I-Nickel 200 nayo ayisebenzi kumagnetic futhi inezinga eliphezulu lokuncibilika, okwenza ibe usizo ezinhlotsheni eziphezulu zokushisa.
I-Nickel201 iwuhlobo oluhlanzekile kakhulu lwensimbi ye-nickel. Iwuhlobo lwe-alloy oluhlanzekile ngokwezentengiselwano, okusho ukuthi iqukethe okuqukethwe kwe-nickel okungenani okungu-99.6%, enamazinga aphansi kakhulu ezinye izakhi. I-Nickel 201 yaziwa ngokumelana kwayo okuhle kakhulu nezindawo ezahlukahlukene ezigqwalisayo, okuhlanganisa ama-asidi, izixazululo ze-alkaline, kanye namanzi olwandle. Iphinde ibonise izakhiwo ezinhle zemishini kanye nokushisa okuphezulu kanye nogesi.
Ezinye izindlela ezijwayelekile zokusebenzisa i-Nickel 201 zifaka phakathi imishini yokucubungula amakhemikhali, ama-evaporator e-caustic, ukukhiqizwa kwe-hydrochloric acid, imishini yezokwelapha, ukukhiqizwa kwefayibha yokwenziwa, kanye nokukhiqizwa kwe-sodium sulfide. Iphinde isetshenziswe ezimbonini zikagesi neze-elekthronikhi ezingxenyeni ezidinga ugesi ophezulu.
Sekukonke, i-Nickel 201 iyaziswa ngenxa yobumsulwa bayo obuphezulu, ukumelana nokugqwala okuhle kakhulu, kanye nokumelana nokuqhekeka emazingeni okushisa aphezulu. Kuyindlela ethembekile yezimboni ezahlukahlukene lapho lezi zakhiwo zidingeka khona.
Omunye wemehluko omkhulu phakathi kweNickel 200 neNickel 201 okuqukethwe kwekhabhoni. I-Nickel 201 inokuqukethwe kwekhabhoni okuphezulu okungu-0.02%, okuphansi kakhulu kunokuqukethwe kwekhabhoni okuphezulu okungu-0.15% kuNickel 200. Lokhu kuqukethwe kwekhabhoni okuncishisiwe kuNickel 201 kunikeza ukumelana okuthuthukisiwe ne-graphitization, inqubo engaholela ekuqhekekeni nasekuncipheni kwamandla kanye nokumelana nomthelela kwe-alloy emazingeni okushisa aphezulu.
Ngenxa yobumsulwa bayo obuphezulu kanye nokumelana okuthuthukisiwe ne-graphitization, i-Nickel 201 ivame ukusetshenziswa ezinhlelweni ezidinga ukuchayeka emazingeni okushisa aphezulu kanye nokunciphisa imimoya. Ivame ukukhethwa kune-Nickel 200 ngenxa yekhono layo lokugcina izakhiwo zayo zemishini kanye nokumelana nokuqhekeka ezindaweni ezinjalo.
I-Nickel iyinsimbi eguquguqukayo futhi esetshenziswa kabanzi ngenxa yezakhiwo zayo ezinhle kakhulu, njengokumelana nokugqwala, ukumelana nokushisa okuphezulu, kanye nokuqhuba kukagesi. Enye yezinsimbi ze-nickel ezidumile yi-Nickel 200, eyaziwa ngobumsulwa bayo kanye nokumelana nokugqwala okuphezulu. Kodwa-ke, kukhona okunye ukuhlukahluka kwale nsimbi ebizwa ngokuthi i-Nickel 201, enokwakheka nezakhiwo ezihlukile kancane. Kulesi sihloko, sizohlola umehluko phakathi kwe-Nickel 200 ne-Nickel 201 kanye nezicelo zazo.
I-Nickel 200 iyi-alloy emsulwa ye-nickel enokuqukethwe okungenani kwe-nickel okungu-99.0%. Yaziwa ngokumelana kwayo okumangalisayo ezindaweni ezahlukahlukene ezigqwalisayo, okuhlanganisa ama-acid, izixazululo ze-alkaline, kanye namanzi olwandle. Lokhu kwenza kube ukukhetha okuhle kakhulu kwezicelo lapho ukumelana nokugqwala kubaluleke kakhulu, njengokucubungula amakhemikhali, ukucubungula ukudla, kanye nezimboni zasolwandle. Ngaphezu kwalokho, i-Nickel 200 ikhombisa ukuhanjiswa kokushisa kanye nogesi okuhle kakhulu, okwenza ifaneleke ezingxenyeni zikagesi neze-elekthronikhi, kanye nezindawo zokushintshanisa ukushisa kanye nezicelo zokushisa okuphezulu.
Kodwa-ke, naphezu kokumelana kwayo okuhle kakhulu nokugqwala, i-Nickel 200 isengozini yokuqhekeka kanye namandla ancishisiwe okushaywa uma ivezwa emazingeni okushisa angaphezu kuka-600°C, ikakhulukazi ekunciphiseni izindawo eziqukethe izakhi zesulfure noma zesulfure. Yilapho i-Nickel 201 iqala khona ukusebenza.
I-Nickel 201 nayo iyi-alloy emsulwa ye-nickel, enokuqukethwe kwekhabhoni okuphansi kancane uma kuqhathaniswa ne-Nickel 200. Okuqukethwe kwekhabhoni okuphezulu kwe-Nickel 201 kungu-0.02%, kuyilapho i-Nickel 200 inokuqukethwe kwekhabhoni okuphezulu okungu-0.15%. Lokhu okuqukethwe kwekhabhoni okuncishisiwe ku-Nickel 201 kunikeza ukumelana okuthuthukisiwe ne-graphitization, inqubo yokwakha izinhlayiya zekhabhoni ezinganciphisa amandla nokuqina kwe-alloy emazingeni okushisa aphezulu. Ngenxa yalokho, i-Nickel 201 ivame ukuthandwa kune-Nickel 200 ezisetshenziswayo ezidinga ukuchayeka emazingeni okushisa aphezulu kanye nokunciphisa imimoya.
Ukumelana ne-graphitization kwenza i-Nickel 201 ifaneleke kakhulu ekusetshenzisweni okubandakanya ama-evaporator e-caustic, ukukhiqizwa kwe-hydrochloric acid, kanye neminye imishini yokucubungula amakhemikhali. Iphinde ithole ukusetshenziswa embonini ye-pulp nephepha, kanye nasekukhiqizweni kwe-fibre yokwenziwa kanye ne-sodium sulfide. Ngaphezu kwalokho, i-Nickel 201 ayisebenzi kumagnetic futhi inezakhiwo ezinhle kakhulu ezifana ne-Nickel 200, njengokumelana nokugqwala okuphezulu, ukuhanjiswa kokushisa, kanye nokuhanjiswa kukagesi.
Ukukhetha phakathi kwe-Nickel 200 ne-Nickel 201 kuncike ezidingweni ezithile zesicelo. Uma ukumelana nokugqwala okuphezulu kuyindaba eyinhloko futhi izinga lokushisa lokusebenza lingadluli ku-600°C, i-Nickel 200 iyisinqumo esihle kakhulu. Okuqukethwe kwayo okuphezulu kwekhabhoni akuvezi zinkinga ezinhlelweni eziningi, futhi inikeza ikhambi elingabizi kakhulu ezimbonini eziningi. Kodwa-ke, uma isicelo sihilela amazinga okushisa aphezulu noma ukwehlisa umoya lapho i-graphitization ingase ivele khona, i-Nickel 201 kufanele icatshangelwe ngokumelana kwayo okuthuthukisiwe kulesi simo.
Kubalulekile ukubonisana nochwepheshe bemboni, njengonjiniyela bezinto ezibonakalayo noma ochwepheshe bezinsimbi, ukuze kutholakale i-nickel alloy efaneleke kakhulu yesicelo esithile. Bangacabangela izici ezifana nendawo yokusebenza, izinga lokushisa, kanye nanoma yiziphi izinkinga ezingaba khona ezihlobene nokuqhekeka noma i-graphitization. Ngobuchwepheshe babo, bangaqondisa abasebenzisi ekwenzeni ukukhetha okufanele kokusebenza kahle kanye nokuphila isikhathi eside.
Ekuphetheni, i-Nickel 200 kanye ne-Nickel 201 zombili ziyi-alloy ze-nickel ezinhle kakhulu ezinomehluko omncane ekubunjweni kanye nezakhiwo. I-Nickel 200 inikeza ukumelana nokugqwala okumangalisayo kanye nokuqhuba kukagesi, kuyilapho i-Nickel 201 inikeza ukumelana okuthuthukisiwe ne-graphitization emazingeni okushisa aphezulu kanye nemimoya enciphisayo. Ukukhetha i-alloy efanele yokusetshenziswa okuthile kuncike ezimweni zokusebenza kanye nezakhiwo ezifiselekayo, futhi kunconywa iseluleko sochwepheshe ukuqinisekisa ukusebenza kahle. Kungakhathaliseki ukuthi yi-Nickel 200 noma i-Nickel 201, lezi alloy ziyaqhubeka nokusetshenziswa kabanzi ezimbonini ezahlukene ngenxa yokuguquguquka kwazo kanye nokuthembeka kwazo.
