Tungsten ucwecwe - kuyini futhi lisetshenziswa lapho?

Ngenxa impahla yayo eziyingqayizivele tungsten ucwecwe kuyinto ejwayelekile. It is lisetshenziswe ezicini eziningi zokuphila, kusukela imithi ziphethe ubunjiniyela, amandla enuzi.

izakhiwo

Naphezu ukujiya ezincane (ka 0.03-0.09 mm), i-tungsten ucwecwe anazo izici owamangaza abantu:

• Heat ukumelana nokushisa ukumelana. ukuphila isikhathi eside, ngisho noma kushisa kuze kufinyelele 2500 degrees.

• kokucindezelwa High (ukunwetshwa) isilinganiso.

• Inani elikhulu ukumelana kagesi.

• ephansi kakhulu ezishisayo ukunwetshwa Coefficient.

• High lokushisa ungangena ukumelana value.

• Amandla.

• A amaphuzu aphezulu electron ekushayweni.

• Akukona adle.

• Amelana amakhemikhali (acid, alkalis, aqua regia).

• Ngokwemithetho yempilo ephephile.

• It is uvunyelwe ukusebenzisa ezonakalisayo lokushisa eliphezulu ezindaweni okuseqophelweni eliphezulu.

Kanye izinzuzo eziningi ezibonakalayo Ubuye nemibi yayo:

• tungsten Pure kunzima ukuthola, kusukela kuba impela ezingavamile.

• I okusezingeni eliphezulu gravity ethize.

• Emazingeni aphansi, indaba iba ziyaqothuka.

• Tungsten - izinto zokusetshenziswa ezingezwakali futhi refractory, okuyinto okunzima ukuba asebenze.

• Ukukhiqizwa kungenzeka kuphela ngaphansi Ukushisa eqinile of izinto zokusetshenziswa.

Ngenxa refractoriness, ukusweleka izinto zokusetshenziswa, nobunzima ngokuhamba aphatha ngayo intengo imikhiqizo siphelile kuphezulu.

ukukhiqizwa

Tungsten UTJHAPHISA ezenziwe metal okumsulwa. AmaSpredishithi akhiqizwa ngokucindezela kufa okulungiselelwe. Ngemva kwalokho, metal ukufuthelana futhi zakhiwa ezingeni lokushisa 1500-1700 degrees.

Ekuvikeleni namachibi usebenzisa metal namanje ugingqe ashisayo ngesivinini. Lapho ukushuba ishidi ifinyelela 0.6 mm, ijubane ugingqe kuyehla. amashidi Iningi mncane etholwe ugingqe abandayo. Ukuze ebusweni ucwecwe abushelelezi, sebenzisa run-in.

Ukuze ukususa amabala namachibi ukusebenzisa isixazululo sodium eshubile. Khona-ke, i-sheet calcined ebukhoneni hydrogen at lokushisa 1000.

sphere kwesicelo

Sebenzisa ucwecwe tungsten (VA 0.05 mm kuhlanganise) ezindaweni eziningi. The main phakathi kwabo kukhona:

• isiqoqi sama-softwe.

• Aircraft.

• amandla enuzi.

• Amafutha umkhakha.

• umkhakha Chemical.

• Radiotehnka.

• Engineering kagesi.

• Medicine.

Tungsten ucwecwe ngenxa impahla yayo esiyingqayizivele isetshenziswa njengoba izivikelo izici yenziwa warmers futhi imishini ukushisa exchange.
