Izinga lokushisa eliphezulu kanye ne-high melting point wire tungsten
Ukukhiqizwa kwentambo ye-tungsten kuhilela izinyathelo ezimbalwa ezibalulekile, ngokuvamile eziqala ngokukhipha insimbi ye-tungsten bese icutshungulwa ibe ifomu locingo.Okulandelayo isingeniso esifushane sendlela yokukhiqiza yocingo lwe-tungsten:
1. Imayini ye-Tungsten ore: I-Tungsten ivamise ukukhishwa ku-ore, ngokuvamile ngendlela yamaminerali e-tungsten oxide, njenge-scheelite noma i-wolframite.I-ore iyambiwa futhi icutshungulwe ukuze kukhishwe ukugxila kwe-tungsten.
2. Ukuguqulwa ku-tungsten powder: I-concentrate ye-tungsten ibe isiguqulwa ngamakhemikhali ibe yi-tungsten oxide, ephinde yehliswe ngenqubo ebizwa ngokuthi i-tungsten oxide ukunciphisa ukuze kukhiqizwe i-tungsten powder.Le powder ye-tungsten iyinhloko yokusetshenziswa kocingo lwe-tungsten.
3. Ukuhlanganiswa kwe-Powder: I-tungsten powder ihlanganiswe ngaphansi kwengcindezi ephezulu ukuze yakhe ibhulokhi eqinile, bese i-sintered ekushiseni okuphezulu ukuze yakhe i-tungsten billet eqinile.Le billet isetshenziswa njengempahla eluhlaza yokukhiqiza induku yocingo.
4. Umdwebo: I-tungsten billet ibe isicutshungulwa ngochungechunge lwemisebenzi yokudweba, idonswe ngochungechunge lwama-dies ukuze kuncishiswe ububanzi bayo obuyisayizi oyifunayo.Inqubo ingase ihlanganise izinyathelo eziningi zokudweba ukuze kuzuzwe ububanzi bocingo lokugcina.
5. Ukufakwa kwe-Annealing: Intambo ye-tungsten edonsayo kufanele idlule enqubweni yokudonsa, lapho ucingo lushiselwa ezingeni lokushisa elithile bese lupholiswa kancane ukuze kuqedwe ukucindezelwa kwangaphakathi futhi kuthuthukiswe ukuduka kwayo nokuguquguquka.
6. Ukwelashwa okungaphezulu: Intambo ye-Tungsten ingaphathwa ngaphezulu, njengokuhlanza, ukumbozwa noma okunye ukuguqulwa kwendawo, ukuze kuthuthukiswe ukusebenza kwayo kwezinhlelo ezithile zokusebenza.
7. Ukulawulwa kwekhwalithi: Kuyo yonke inqubo yokukhiqiza, izinyathelo zokulawula ikhwalithi ziyasetshenziswa ukuze kuqinisekiswe ukuthi intambo ye-tungsten ihlangabezana nezidingo ezicacisiwe zobukhulu, zemishini namakhemikhali.
Sekukonke, ukukhiqizwa kocingo lwe-tungsten kuhilela uchungechunge lwezinyathelo ezilawulwa ngokucophelela, kusukela ekukhishweni kwensimbi ye-tungsten kuya ekudwebeni kokugcina nokucutshungulwa.Inqubo idinga ukunemba nobungcweti ukuze kukhiqizwe ucingo lwe-tungsten olusezingeni eliphezulu olufanele izinhlelo zokusebenza ezihlukene zezimboni.
I-Tungsten wire isetshenziswa kabanzi ezimbonini ezahlukahlukene ngenxa yezakhiwo zayo ezihlukile.Ezinye izinto ezisetshenziswayo ze-tungsten wire zihlanganisa:
1. Ukukhanyisa: I-Tungsten filament isetshenziswa kakhulu ekukhiqizeni ama-incandescent amalambu namalambu e-halogen.Ngenxa yezinga eliphezulu lokuncibilika kanye nokuhamba kahle kukagesi, isetshenziswa njengefilament kulezi zicelo zokukhanyisa.
2. Izinto zikagesi nezikagesi: Intambo ye-Tungsten isetshenziswa ezintweni ezihlukahlukene zikagesi nezikagesi, okuhlanganisa amashubhu evacuum, amashubhu e-cathode ray (CRT), kanye nemishini yokushisela i-electron beam.Iphuzu layo eliphezulu lokuncibilika kanye nokumelana nokwanda kokushisa kuyenza ifanele lezi zicelo zokushisa okuphezulu.
3. Izakhi zokushisa: Intambo ye-Tungsten isetshenziselwa ukukhiqiza izinto zokushisisa zezithando zokushisa eziphezulu, imishini yokukhiqiza i-semiconductor, nezinye izinhlelo zokusebenza zokushisa ezimbonini.Ikhono layo lokumelana namazinga okushisa aphakeme kakhulu ngaphandle kokuguqulwa noma i-oxidation iyenza ibe yigugu kulokhu kusetshenziswa.
4. I-Aerospace kanye Nokuvikela: I-Tungsten filament isetshenziswa kwi-aerospace nezinhlelo zokuvikela, njengezintambo ezisetshenziswa ekukhiqizeni amasistimu okuqondisa imicibisholo, izinyathelo zokuphikisa zika-elekthronikhi, nezinye izisetshenziswa zezempi ze-elekthronikhi.
5. Imishini yezokwelapha: Intambo ye-Tungsten isetshenziswa emishinini yezokwelapha, okuhlanganisa amashubhu e-X-ray, imishini yokwelapha nge-radiotherapy nezinsimbi ezihlukahlukene zokuhlinza.Ukuminyana kwayo okuphezulu namandla kuyenza ifanele lezi zicelo zezokwelapha ezibucayi.
6. Ukuhlunga nokuhlola: I-Tungsten wire mesh isetshenziswa ekuhlungeni nasekuhloleni izinhlelo zokusebenza ezimbonini ezinjengokucubungula amakhemikhali, i-aerospace, nezimoto.Amandla aphezulu entambo yocingo kanye nokumelana nokugqwala kuyenza ifanelekele lezi zindawo ezinokhahlo.
7. Izinzwa Zokushisa Eziphakeme: Intambo ye-Tungsten isetshenziselwa ukwakha izinzwa zokushisa eziphezulu zezinhlelo zokusebenza zezimboni, ezifana nokuqapha nokulawula izinqubo zokushisa okuphezulu ezindaweni zokukhiqiza nezokucwaninga.
Sekukonke, inhlanganisela eyingqayizivele yendawo yokuncibilika okuphezulu, ukuqhutshwa kukagesi, namandla kwenza intambo ye-tungsten ibe yinto ebalulekile enezinhlobonhlobo zezinhlelo zokusebenza ezimbonini ezifana nezibani, izinto zikagesi, i-aerospace, ezokwelashwa, nezimboni zokukhiqiza.
