I-Tungsten iyinsimbi engavamile, ebukeka njengensimbi. Sekuyinto ebaluleke kakhulu esebenzayo embonini yesimanje, ukuvikela izwe kanye nezicelo zobuchwepheshe obuphezulu ngenxa yezinga eliphezulu lokuncibilika, ukuqina okuphezulu, ukumelana nokugqwala okuhle kakhulu kanye nokuhamba kahle kukagesi nokushisa. Yiziphi izinkambu ezithile zokusetshenziswa kwe-tungsten?
1. Inkambu yengxubevange
insimbi
Ngenxa yokuqina kwayo okuphezulu nokuqina okuphezulu, i-tungsten iyisici esibalulekile se-alloy ngoba ingathuthukisa kakhulu amandla, ubulukhuni nokumelana nokugqoka kwensimbi. Isetshenziswa kabanzi ekukhiqizeni izinsimbi ezihlukahlukene. I-tungsten evamile equkethe izinsimbi ihlanganisa insimbi enesivinini esikhulu, insimbi ye-tungsten nensimbi kazibuthe ye-tungsten cobalt. Asetshenziswa kakhulu ukwenza amathuluzi ahlukahlukene, njengama-drill bits, ama-milling cutters, isikhunta sabesifazane kanye nesikhunta sabesilisa.
I-tungsten carbide esekwe nge-cemented carbide
I-Tungsten carbide inokumelana nokugqoka okuphezulu kanye ne-refractory, futhi ubulukhuni bayo buseduze nedayimane, ngakho-ke ivame ukusetshenziswa ekukhiqizeni i-carbide enosimende. I-Tungsten carbide esekwe nge-cemented carbide ingahlukaniswa izigaba ezine: i-tungsten carbide cobalt, i-tungsten carbide titanium carbide cobalt, i-tungsten carbide titanium carbide tantalum (i-niobium) - i-cobalt nensimbi eboshwe nge-cemented carbide. Zisetshenziswa kakhulu ukwenza amathuluzi okusika, amathuluzi ezimayini kanye nokudweba ngocingo kuyafa.

Gqoka ingxubevange engazweli
I-Tungsten iyinsimbi ephikisayo enephuzu eliphakeme kakhulu lokuncibilika (imvamisa ephakeme kuno-1650 ℃), enokuqina okuphezulu, ngakho-ke ivame ukusetshenziselwa ukwenza amandla okushisa nama-alloys angagugi, njengama-alloys e-tungsten ne-chromium, i-cobalt ne-carbon, ezivame ukusetshenziselwa ukukhiqiza izingxenye ezingagugi njenge-valve ye-aeroengine kanye ne-turbine impeller, Ama-alloys e-tungsten nezinye izinsimbi eziphikisayo (njenge-tantalum, i-niobium, i-molybdenum ne-rhenium) zivame ukusetshenziselwa ukukhiqiza izingxenye ezinamandla ezishisayo ezifana ne-rocket. nozzle kanye nenjini.
High specific gravity ingxubevange
I-Tungsten isiphenduke into efanelekile yokukhiqiza ama-alloys athile adonsela phansi athile ngenxa yokuminyana kwayo okuphezulu nobulukhuni obuphezulu. Ngokwezici zokuqamba ezihlukene kanye nokusetshenziswa, lawa ma-alloys aphezulu adonsela phansi angahlukaniswa abe yi-W-Ni-Fe, W-Ni-Cu, W-Co, w-wc-cu, W-Ag nolunye uchungechunge. Zivame ukusetshenziselwa ukukhiqiza izinto zokuxhumana ezifana nezikhali, ishidi lokukhipha ukushisa, ukushintshwa kommese, i-circuit breaker nokunye ngenxa yamandla adonsela phansi athile amakhulu, amandla aphezulu, ukuqhutshwa kokushisa okuphezulu, ukuqhutshwa kahle kukagesi kanye nokusebenza okuphakeme kokucubungula.
2. Inkambu ye-elekthronikhi
I-Tungsten isetshenziswa kakhulu embonini ye-elekthronikhi namandla ngenxa yepulasitiki yayo eqinile, izinga eliphansi lokuhwamuka, indawo ephezulu yokuncibilika kanye nekhono eliqinile lokuphuma kwama-electron. Isibonelo, i-tungsten filament inezinga eliphezulu elikhanyayo nempilo ende yesevisi, futhi ivame ukusetshenziselwa ukwenza ama-bulb filaments ahlukahlukene, njengesibani se-incandescent, isibani se-iodine tungsten nokunye. Ngaphezu kwalokho, i-tungsten wire ingasetshenziswa futhi ukwenza i-cathode eshisayo eqondile kanye negridi ye-electronic oscillation tube kanye ne-cathode heater kumathuluzi ahlukahlukene kagesi.
3, Imboni yamakhemikhali
Izinhlanganisela ze-Tungsten zivame ukusetshenziselwa ukukhiqiza izinhlobo ezithile zopende, izingulube, iziyinki, izinto zokuthambisa kanye nama-catalysts. Isibonelo, i-sodium tungstate ivame ukusetshenziswa ekwenzeni i-tungsten yensimbi, i-tungstic acid ne-tungstate, kanye nodayi, izingulube, iziyinki, i-electroplating, njll; I-Tungstic acid ivame ukusetshenziswa njenge-mordant kanye nodayi embonini yendwangu kanye ne-catalyst yokulungiselela uphethiloli we-octane ephezulu embonini yamakhemikhali; I-Tungsten disulfide ivame ukusetshenziswa ku-organic synthesis, njenge-lubricant eqinile kanye ne-catalyst ekulungiseleleni uphethiloli wokwenziwa; I-bronze tungsten oxide isetshenziswa ekudwebeni.

4, Inkambu yezokwelapha
Ngenxa yokuqina nokuqina kwayo okuphezulu, ingxubevange ye-tungsten ifaneleka kakhulu emikhakheni yezokwelapha efana ne-X-ray nokuvikelwa kwemisebe. Imikhiqizo yezokwelapha evamile ye-tungsten alloy ihlanganisa i-X-ray anode, i-anti scattering plate, isitsha esikhipha imisebe kanye nesiqukathi sokuvikela isirinji.
5. Inkundla yezempi
Ngenxa yezindawo zayo ezingenabo ubuthi nezivumelana nemvelo, imikhiqizo ye-tungsten iye yasetshenziswa esikhundleni somthofu wangaphambili kanye nezinto ezisetshenziswayo ze-uranium ezinciphile ukwenza amakhanda ezinhlamvu, ukuze kwehliswe ukungcoliswa kwezinto zempi endaweni yemvelo. Ngaphezu kwalokho, ngenxa yezimpawu zokuqina okuqinile kanye nokumelana okuhle kokushisa okuphezulu, i-tungsten ingenza ukusebenza kokulwa kwemikhiqizo yezempi elungiselelwe kuphakeme kakhulu. Imikhiqizo ye-Tungsten esetshenziswa kwezempi ikakhulukazi ihlanganisa izinhlamvu ze-tungsten alloy kanye nezinhlamvu zokubhoboza zezikhali ze-kinetic.
Ngaphezu kwezinkambu ezingenhla, i-tungsten ingasetshenziswa futhi ku-aerospace, ukuhamba, amandla e-athomu, ukwakhiwa kwemikhumbi, imboni yezimoto kanye neminye imikhakha.
