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 nonyango 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.
