Inkambu yohlelo lokusebenza lwe-tungsten

I-Tungsten eyaziwa nangokuthi i-wolfram, iyikhemikhali enophawu luka-W kanti inombolo ye-athomu ingu-74. Iyinsimbi eyingqayizivele enohlu olubanzi lokusebenza kwezobuchwepheshe besimanje. Insimbi ye-Tungsten iyinsimbi eqinile futhi eyivelakancane. Ingatholakala kuphela emhlabeni kuma-chemical compounds. Iningi lamakhemikhali ayo ama-tungsten oxide futhi iningi lezimayini ze-tungsten zatholakala eShayina. Ikakhulukazi ezifundazweni zaseHunan naseJiangxi. Ngenxa yezinga eliphezulu lokuncibilika kwayo, ukuqina kwayo okuphezulu, ukumelana nokugqwala okuhle kakhulu, ukuguquguquka okuhle kukagesi, kanye ne-thermal conductivity, isibe enye yezinto ezibaluleke kakhulu zokusebenza embonini yesimanje. Isetshenziswa kabanzi ku-alloy, electronics, chemical, medical, kanye neminye imikhakha.

1. Emkhakheni we-Industrial alloys

I-powder metallurgy iyindlela yokukhiqiza imikhiqizo ye-tungsten sintered. I-Tungsten powder iyimpahla eluhlaza ebaluleke kakhulu kanye nendawo yokuqala yemikhiqizo yamaminerali e-tungsten. I-Tungsten powder yenziwa ngokugazinga nokushisisa i-tungsten oxide emkhathini we-hydrogen. Ukuhlanzeka, umoya-mpilo, nosayizi wezinhlayiyana kubaluleke kakhulu ekulungiseni impushana ye-tungsten. Ingaxutshwa nezinye izinto eziyimpushana ukwenza ingxubevange yama-tungsten alloys.

I-tungsten carbide eyenziwe nge-cemented carbide:

I-Tungsten carbide ivame ukusetshenziselwa ukuxuba nezinye izinsimbi ukuthuthukisa ukusebenza kwayo. Izinsimbi ezixubene zihlanganisa i-cobalt, i-titanium, insimbi, isiliva, ne-tantalum. Umphumela uba ukuthi i-tungsten carbide-based cemented carbide inokumelana nokugqokwa okuphezulu kanye nezakhiwo eziphakeme zokuphikisa. Zisetshenziswa kakhulu ekukhiqizeni amathuluzi okusika, amathuluzi ezimayini, i-wire drawing dies, njll. Imikhiqizo ye-carbide enosimende esekwe e-Tungsten ithandwa ngisho kunensimbi engagqwali ngenxa yokuqina kwayo okumangalisayo nokumelana nokuguga. Ingasetshenziswa kabanzi ezinhlelweni zokwakha ezentengiselwano, izinto zikagesi, ukwenza amagiya ezimboni, izinto zokuvikela imisebe, kanye nemboni yezokundiza.

Ingxubevange ekwazi ukumelana nokushisa nengagugi:

Indawo encibilikayo ye-tungsten iphakeme kakhulu kuzo zonke izinsimbi, futhi ukuqina kwayo kungokwesibili ngemva kwedayimane. Ngakho-ke kuvame ukusetshenziselwa ukukhiqiza ama-alloys angavimbeli ukushisa futhi angagugi. Isibonelo, ama-alloys e-tungsten nezinye izinsimbi eziphikisayo (i-tantalum, i-molybdenum, i-hafnium) ngokuvamile akhiqizwa izingxenye ezinamandla kakhulu njengama-nozzles nezinjini zamarokhethi. Futhi ama-alloys e-tungsten, i-chromium, ne-carbon avame ukusetshenziselwa ukukhiqiza izingxenye ezinamandla kakhulu nezingagugi, njengama-valve ezinjini zezindiza, amasondo omoya, njll.

2. Emkhakheni wamakhemikhali

Izinhlanganisela ze-Tungsten zivame ukusetshenziselwa ukukhiqiza izinhlobo ezithile zopende, oyinki, izinto zokuthambisa, kanye nama-catalyst. Isibonelo, i-tungsten oxide enombala wethusi isetshenziswa ekudwebeni, kanti i-calcium noma i-magnesium tungsten ivame ukusetshenziswa kumaphosphors.

3. Emkhakheni wezempi

Imikhiqizo ye-Tungsten isetshenziselwe ukufaka esikhundleni somthofu kanye nezinto ezisetshenziswayo ze-uranium eseziphelile ukwenza ama-warheads ezinhlamvu ngenxa yezindawo zawo ezingenabuthi kanye nokuvikela imvelo, ukuze kwehliswe ukungcoliswa kwezinto zempi endaweni yemvelo. Ngaphezu kwalokho, i-tungsten ingenza ukusebenza kokulwa kwemikhiqizo yezempi kuphakame ngenxa yokuqina kwayo okuqinile nokumelana okuhle nezinga lokushisa eliphezulu.

I-Tungsten ingasetshenziswa hhayi emikhakheni engenhla kuphela kodwa nasekuhambeni, amandla e-athomu, ukwakhiwa kwemikhumbi, imboni yezimoto, neminye imikhakha. Uma uthanda i-tungsten noma unemibuzo ngayo. Sicela usithinte manje.
