kuyilapho kokubili i-Nickel 200 kanye ne-Nickel 201 kuyingxube ye-nickel ehlanzekile, i-Nickel 201 inokumelana kangcono nokunciphisa izindawo ngenxa yokuqukethwe kwayo kwekhabhoni ephansi. Ukukhetha phakathi kwakho kokubili kuzoncika ezidingweni ezithile zohlelo lokusebenza kanye nendawo lapho okuzosetshenziswa khona.
I-Nickel 200 ne-Nickel 201 womabili ama-alloys e-nickel ahlanzekile ahluke kancane ekwakhekeni kwawo kwamakhemikhali.
I-Nickel 200 iyingxubevange ye-nickel eyi-ferromagnetic, emsulwa kwezohwebo (99.6%) enezakhiwo ezinhle zokusebenza kanye nokumelana okuhle kakhulu nezindawo ezigqwalile, okuhlanganisa ama-asidi, ama-alkaline, nezixazululo ezingathathi hlangothi. Inokumelana nogesi okuphansi, okuyenza ifaneleke izinhlelo zikagesi neze-elekthronikhi.
I-Nickel 201, ngakolunye uhlangothi, iyingxube ye-nickel ehlanzekile kwezohwebo (99.6%) kodwa inokuqukethwe kwekhabhoni ephansi uma kuqhathaniswa ne-Nickel 200. Lokhu okuqukethwe kwekhabhoni ephansi kunikeza i-Nickel 201 ukumelana kangcono nokugqwala ezindaweni ezinciphisayo, ezifana ne-sulfuric acid. Ibuye isetshenziswe ngokujwayelekile ekucubunguleni amakhemikhali, izakhi ze-elekthronikhi, namabhethri aphinde ashajwe.
Kafushane, ngenkathi zombili i-Nickel 200 ne-Nickel 201 zingama-nickel alloys ahlanzekile, i-Nickel 201 inokumelana kangcono nokunciphisa izindawo ngenxa yokuqukethwe kwayo kwekhabhoni ephansi. Ukukhetha phakathi kwakho kokubili kuzoncika ezidingweni ezithile zohlelo lokusebenza kanye nendawo lapho okuzosetshenziswa khona.
I-Nickel200 iyingxube ye-nickel ekhandiwe ngaphandle kwezentengiselwano equkethe i-nickel engu-99.6%. Yaziwa ngokumelana nokugqwala okuhle kakhulu, ukuguquguquka okuphezulu kwe-thermal kanye nogesi, okuqukethwe kwegesi ephansi, kanye nezakhiwo ezinhle zemishini. Ingenziwa kalula futhi inamazinga aphansi okukhasa, okuyenza ifanelekele uhla olubanzi lwezinhlelo zokusebenza ezihlanganisa ukucubungula amakhemikhali, izingxenye zikagesi, nezindawo zasolwandle. I-Nickel 200 nayo ayiwona uzibuthe futhi inephuzu eliphezulu lokuncibilika, okuyenza ibe wusizo ezinhlelweni zokushisa ezisezingeni eliphezulu.
I-Nickel201 iyindlela yokuhlanzeka okuphezulu kwensimbi ye-nickel. I-alloy emsulwa kwezohwebo, okusho ukuthi iqukethe ubuncane be-nickel obungu-99.6%, namazinga aphansi kakhulu ezinye izici. I-Nickel 201 yaziwa ngokumelana kwayo okuhle kakhulu nezindawo ezonakalisayo ezihlukahlukene, okuhlanganisa ama-acids, izixazululo ze-alkaline, namanzi olwandle. Ibuye ibonise izakhiwo ezinhle zemishini kanye ne-high conductivity eshisayo nekagesi.
Ezinye izinhlelo zokusebenza ezijwayelekile ze-Nickel 201 zihlanganisa imishini yokucubungula amakhemikhali, ama-evaporator e-caustic, ukukhiqizwa kwe-hydrochloric acid, okokusebenza kwemithi, ukukhiqizwa kwefayibha yokwenziwa, nokukhiqizwa kwe-sodium sulfide. Ibuye isetshenziswe ezimbonini zikagesi neze-elekthronikhi ezingxenyeni ezidinga ukuhanjiswa kukagesi okuphezulu.
Sekukonke, i-Nickel 201 ibaluleke kakhulu ngenxa yobumsulwa bayo obuphezulu, ukumelana nokugqwala okuhle kakhulu, kanye nokumelana ne-embrittlement emazingeni okushisa aphezulu. Kuyisinqumo esithembekile sezimboni ezahlukahlukene lapho kudingeka khona lezi zakhiwo.
Omunye umehluko omkhulu phakathi kwe-Nickel 200 ne-Nickel 201 okuqukethwe kwekhabhoni. I-Nickel 201 inokuqukethwe okuphezulu kwekhabhoni okungu-0.02%, okuphansi kakhulu kunokuqukethwe okuphezulu kwekhabhoni okungu-0.15% ku-Nickel 200. Lokhu okuqukethwe kwekhabhoni encishisiwe ku-Nickel 201 kunikeza ukumelana okuthuthukisiwe ku-graphitization, inqubo engaholela ekubambeni nasekunciphiseni amandla. kanye nokumelana nomthelela we-alloy emazingeni okushisa aphezulu.
Ngenxa yokuhlanzeka kwayo okuphezulu nokumelana okuthuthukisiwe ku-graphitization, i-Nickel 201 ivamise ukusetshenziswa ezinhlelweni ezidinga ukuchayeka kumazinga okushisa aphakeme kanye nokunciphisa umkhathi. Ivame ukukhethwa ngaphezu kwe-Nickel 200 ngenxa yekhono layo lokulondoloza izakhiwo zayo zemishini kanye nokumelana nokuvuthwa ezindaweni ezinjalo.
I-Nickel iyinsimbi eguquguqukayo futhi esetshenziswa kabanzi ngenxa yezakhiwo zayo ezinhle kakhulu, njengokumelana nokugqwala, ukumelana nokushisa okuphezulu, kanye nokuhamba kukagesi. Enye ye-nickel alloys edumile i-Nickel 200, eyaziwa ngobumsulwa bayo kanye nokumelana nokugqwala okuphezulu. Kodwa-ke, kunolunye uhlobo lwale alloy ebizwa nge-Nickel 201, enokwakheka okuhlukile kanye nezakhiwo. Kulesi sihloko, sizohlola umehluko phakathi kwe-Nickel 200 ne-Nickel 201 kanye nezinhlelo zokusebenza ezihlukene.
I-Nickel 200 iyingxubevange ye-nickel ehlanzekile enokuqukethwe kwe-nickel okungenani okungu-99.0%. Yaziwa ngokumelana kwayo okuyingqayizivele nezindawo ezonakalisayo ezihlukahlukene, okuhlanganisa ama-acids, izixazululo ze-alkaline, namanzi olwandle. Lokhu kukwenza kube ukukhetha okuhle kwezinhlelo zokusebenza lapho ukumelana nokugqwala kubalulekile, njengokucutshungulwa kwamakhemikhali, ukucubungula ukudla, nezimboni zasolwandle. Ukwengeza, i-Nickel 200 ibonisa ukuhamba kahle kwe-thermal kanye nogesi, okwenza ifaneleke izingxenye zikagesi neze-elekthronikhi, kanye nezishintshisi zokushisa kanye nezicelo ezishisa kakhulu.
Nokho, naphezu kokumelana kwayo nokugqwala okuhle kakhulu, i-Nickel 200 isengozini yokuncipha kanye namandla omthelela ancishisiwe lapho evezwe emazingeni okushisa angaphezu kuka-600°C, ikakhulukazi ekwehliseni indawo equkethe izinhlanganisela zesulfure noma isulfure. Yilapho i-Nickel 201 iqala khona ukudlala.
I-Nickel 201 nayo iyingxubevange ye-nickel ehlanzekile, enokuqukethwe kwekhabhoni ephansi kancane uma kuqhathaniswa ne-Nickel 200. I-carbon content ye-Nickel 201 ingu-0.02%, kuyilapho i-Nickel 200 ine-carbon content engu-0.15%. Lokhu okuqukethwe kwekhabhoni encishisiwe ku-Nickel 201 kunikeza ukumelana okuthuthukisiwe ku-graphitization, inqubo yokwenza izinhlayiya zekhabhoni ezinganciphisa amandla e-alloy kanye nokuqina emazingeni okushisa aphezulu. Njengomphumela, i-Nickel 201 ivame ukuthandwa kune-Nickel 200 ezinhlelweni ezidinga ukuchayeka emazingeni okushisa aphakeme kanye nokunciphisa umkhathi.
Ukumelana ne-graphitization kwenza i-Nickel 201 ifanelekele kakhulu izinhlelo zokusebenza ezifaka ama-evaporator e-caustic, ukukhiqizwa kwe-hydrochloric acid, nezinye izinto zokusebenza zokucubungula amakhemikhali. Iphinde ithole ukusetshenziswa embonini ye-pulp nephepha, kanye nasekukhiqizeni i-synthetic fiber ne-sodium sulfide. Ukwengeza, i-Nickel 201 ayiwona uzibuthe futhi yabelana ngezakhiwo ezinhle kakhulu ezifana ne-Nickel 200, njengokumelana nokugqwala okuphezulu, ukuqhutshwa kwe-thermal, kanye ne-conductivity kagesi.
Ukukhetha phakathi kwe-Nickel 200 ne-Nickel 201 kuncike ezimfuneko ezithile zohlelo lokusebenza. Uma ukumelana nokugqwala okuphezulu kuwukukhathazeka okuyinhloko futhi izinga lokushisa lokusebenza alidluli ku-600 ° C, i-Nickel 200 iyisinqumo esihle kakhulu. Okuqukethwe kwekhabhoni ephezulu akuzibambi izinkinga ezinhlelweni eziningi, futhi kunikeza isixazululo esingabizi kakhulu ezimbonini eziningi. Kodwa-ke, uma uhlelo lokusebenza lubandakanya amazinga okushisa aphezulu noma ukunciphisa umkhathi lapho i-graphitization ingase yenzeke, i-Nickel 201 kufanele icatshangelwe ngenxa yokumelana kwayo okuthuthukisiwe kulokhu.
Kubalulekile ukubonisana nochwepheshe bemboni, njengonjiniyela bezinto ezibonakalayo noma i-metallurgists, ukuthola ingxube ye-nickel efaneleke kakhulu yohlelo oluthile. Bangacabangela izici ezifana nendawo yokusebenza, izinga lokushisa, nanoma yikuphi ukukhathazeka okungaba khona okuhlobene ne-embrittlement noma i-graphitization. Ngobuchwepheshe babo, bangaqondisa abasebenzisi ekwenzeni ukukhetha okulungile kokusebenza okuphezulu nokuphila isikhathi eside.
Sengiphetha, i-Nickel 200 ne-Nickel 201 zombili zingamaalloyi e-nickel amahle kakhulu anomehluko omncane ekubunjweni nasezimpahleni. I-Nickel 200 inikeza ukumelana nokugqwala okukhethekile kanye nokuhamba kukagesi, kuyilapho i-Nickel 201 inikeza ukumelana okuthuthukisiwe ku-graphitization emazingeni okushisa aphezulu kanye nokunciphisa umkhathi. Ukukhetha i-alloy efanele yesicelo esithile kuncike ezimweni zokusebenza kanye nezakhiwo ezifunwayo, futhi iseluleko sochwepheshe sinconywa ukuze kuqinisekiswe ukusebenza kahle. Kungakhathaliseki ukuthi i-Nickel 200 noma i-Nickel 201, lawa ma-alloys ayaqhubeka nokusetshenziswa kabanzi ezimbonini ezihlukahlukene ngenxa yokuhlukahluka nokuthembeka.
