Izinto zokufudumeza ezenziwe nge-tungsten zisetyenziswa kwizicelo ezahlukeneyo zobushushu obuphezulu ngenxa yeempawu ezikhethekileyo ze-tungsten, njengendawo yayo ephezulu yokunyibilika, ukomelela okubalaseleyo kumaqondo obushushu aphezulu, kunye noxinzelelo lomphunga ophantsi.Nazi ezinye iintlobo eziqhelekileyo zezinto zokufudumeza ezisebenzisa i-tungsten:

1. Tungsten Wire Heating Elements: Intambo ye-Tungsten isetyenziswa ngokuqhelekileyo njengento yokufudumala kwizicelo ezifana nezibane ze-incandescent, apho isebenza njenge-filament eshushu kwaye ivelise ukukhanya xa umbane udlula kuyo.Izinto zokufudumeza ngocingo lweTungsten zikwasetyenziswa kwiziko loshishino, ii-oveni, kunye neenkqubo zokufudumeza ezifuna ukusebenza kobushushu obuphezulu.

2. I-Tungsten Ribbon Heating Elements: Iribhoni ye-Tungsten, ifom ye-flat kunye nebanzi yocingo lwe-tungsten, isetyenziselwa izinto zokufudumeza kwizicelo ezifuna indawo enkulu yokuvelisa ukushisa.Izinto zokufudumeza iiribhoni zeTungsten zisetyenziswa kwiinkqubo ezahlukeneyo zokufudumeza kwimizi-mveliso, kubandakanywa unyango lobushushu, i-annealing, kunye nokunyibilika kwesinyithi.

3. I-Tungsten Foil Heating Elements: I-tungsten foil, eluhlobo oluthile kunye ne-flexible ye-tungsten, isetyenziswe kwizinto ezikhethekileyo zokufudumeza izicelo ezifuna ukufudumeza okuchanekileyo kunye okufanayo.Izinto zokufudumeza ze-Tungsten foil zisetyenziswa kumashishini afana nokuveliswa kwe-semiconductor, i-aerospace, kunye nokukhusela.

4. I-Tungsten Disilicide (WSi2) I-Heating Elements: Izinto zokufudumala ze-Tungsten ze-disilicide zenziwe nge-compound ye-tungsten kunye ne-silicon, enikezela ukuchasana nokushisa okuphezulu kunye nokuchasana kwe-oxidation.Ezi zinto zokufudumeza zisetyenziswa kwiziko lobushushu obuphezulu, ii-kilns, kunye nezinye izicelo zokufudumeza kwimizi-mveliso.

Ngokubanzi, izinto zokufudumeza ezenziwe nge-tungsten zixabiswa ngenxa yokukwazi ukumelana nobushushu obugqithisileyo, ukubonelela ngokuvelisa ubushushu obusebenzayo, kunye nokugcina imfezeko yesakhiwo ekufuneni indawo ezinobushushu obuphezulu.Ezi zinto zifumana ukusetyenziswa kuluhlu olubanzi lweenkqubo zokufudumeza kwezoshishino, urhwebo, kunye nenzululwazi.

I-Tungsten yaziwa ngokuxhathisa kwayo okukhethekileyo ekuphenduleni ngezinto ezininzi kumaqondo obushushu aqhelekileyo.Eli nqanaba liphezulu le-inertness yeekhemikhali ngenxa yeebhondi eziqinileyo ze-athomu kunye nokwakheka komgangatho okhuselekileyo we-oxide phezu kwawo.Nangona kunjalo, i-tungsten inokusabela ngezinto ezithile phantsi kweemeko ezithile:

1. Ioksijini: I-Tungsten inokusabela ngeoksijini kumaqondo obushushu aphezulu ukwenza i-tungsten oxides.Oku kusabela kwenzeka kumaqondo obushushu aphakamileyo, ngokuqhelekileyo ngaphezu kwe-700 ° C, apho i-tungsten inokukhupha i-oxidize ukwenza i-oxides efana ne-tungsten trioxide (WO3) kunye ne-tungsten dioxide (WO2).

2. I-Halogens: I-Tungsten inokusabela kunye ne-halogens ezifana ne-fluorine, i-chlorine, i-bromine, kunye ne-iodine kumaqondo obushushu aphezulu ukwenza i-tungsten halides.Ezi ntshukumo zenzeke phantsi kweemeko ezigqithisileyo kwaye azixhaphakanga kwizicelo zemihla ngemihla.

3. Ikhabhoni: I-Tungsten inokusabela ngekhabhoni kwiqondo lokushisa eliphezulu kakhulu ukuze yenze i-tungsten carbide (WC), into enzima kunye ne-resistant-resistant material.Oku kusabela kudla ngokusetyenziswa kwimveliso ye-tungsten carbide yezixhobo zokusika kunye nezinye izicelo zoshishino.

Ngokubanzi, i-reactivity ye-tungsten kunye nezinto ezininzi incinci phantsi kweemeko eziqhelekileyo, iyenza ukuba ixhathise kakhulu kwi-corrosion kunye nokuhlaselwa kweekhemikhali.Le propati yenza i-tungsten ixabiseke kuluhlu olubanzi lwezicelo apho ukungabikho kweekhemikhali kunye nokuzinza kobushushu obuphezulu kubalulekile.
