Ukumelana nobushushu obuphezulu be-MLa Wire
Iindidi ezininzi zocingo ziyilelwe ukumelana namaqondo obushushu aphezulu, kuquka:
1. I-alloys esekelwe kwi-nickel: Iingcingo ze-nickel-based welding, ezifana ne-Inconel kunye ne-nichrome, ziyaziwa ngokumelana nokushisa okuphezulu kwaye zihlala zisetyenziselwa izicelo ezifuna ukuxhathisa ukushisa, njengezinto zokufudumala kunye neziko zoshishino.
2. I-Tungsten: Intambo ye-Tungsten inomlinganiselo ophezulu kakhulu wokunyibilika kwaye isetyenziselwa izicelo zokushisa eziphezulu ezifana ne-incandescent light bulbs kunye nezinto zokufudumeza kwiziko lobushushu obuphezulu.
3. I-Molybdenum: I-Molybdenum wire nayo inendawo ephezulu yokunyibilika kwaye isetyenziswa kwizicelo zobushushu obuphezulu, kubandakanywa i-aerospace kunye ne-electronics industry.
4. IPlatinam: Ucingo lwePlatinam luyaziwa ngokuzinza kobushushu obuphezulu kwaye lusetyenziswa kwizixhobo zelabhoratri, i-thermocouples kunye nezinye izicelo zobushushu obuphezulu.
Ezi ngcingo zenzelwe ngokukodwa ukujamelana nokushisa okukhulu kwaye zisetyenziselwa kwiindidi ezahlukeneyo zoshishino, isayensi kunye nezobugcisa ezifuna ukumelana nokushisa okuphezulu.
Ngokuqhelekileyo, ucingo olushushu lunokumelana okuphezulu kunocingo olubandayo. Oku kungenxa yokuba ukuchasana kwezinto ezininzi kunyuka ngobushushu. Olu lwalamano luchazwa ngumlinganiso weqondo lokushisa lokumelana, obonisa ukuba ukuchasana kwezinto eziphathekayo kutshintsha kangakanani nobushushu.
Xa ucingo lufudunyezwa, ukonyuka kwamandla obushushu kubangela ukuba ii-athom ezisemathiriyelini zingcangcazele ngamandla, nto leyo ekhokelela ekungqubaneni okukhulu nomsinga we-electron. Oku kwanda kwe-athom vibration kuthintela ukuhamba kwee-electron, kubangela ukuxhathisa okuphezulu ekuhambeni kombane.
Ngokuchasene noko, njengoko ucingo luphola, ukuncitshiswa kwamandla obushushu kubangela ukuba iiathom zingcangcazele kancinci, ngaloo ndlela kunciphisa ukuxhathisa ukuhamba kombane.
Kuyafaneleka ukuba uqaphele ukuba olu lwalamano phakathi kweqondo lokushisa kunye nokuchasana alusebenzi kuzo zonke izinto, njengoko ezinye izinto zingabonakalisa i-coefficient yeqondo lokushisa elibi lokumelana, oku kuthetha ukuba ukuchasana kwabo kunciphisa njengoko ubushushu bukhula. Nangona kunjalo, kwizinto ezininzi eziqhelekileyo zokuqhuba, kubandakanya iintsimbi ezifana nobhedu kunye ne-aluminiyam, ukuxhathisa kukhula ngobushushu.
Xa iingcingo zinokuchasana okuphezulu, imiphumo eyahlukeneyo kunye nemiphumo ingenzeka, kuxhomekeke kwimeko kunye nesicelo. Nazi iziphumo eziqhelekileyo zeengcingo ezixhathisayo eziphezulu:
1. Ukufudumeza: Xa umsinga wombane udlula kwi-high-resistance wire, ubushushu obukhulu buveliswa. Le propati ingasetyenziselwa izinto zokufudumeza ezifana nezo zifumaneka kwii-toaster, izitofu zombane kunye neziko loshishino.
2. Ukuwa kweVoltage: Kwisekethe, iingcingo ezixhathisayo zinokubangela ukuhla kwamandla ombane abalulekileyo ngobude bocingo. Oku kunokuchaphazela ukusebenza kwesiphaluka kunye nokusebenza kwezixhobo ezixhunyiwe.
3. Ukulahlekelwa kwamandla: Iingcingo ezixhathisayo eziphezulu zibangela ukuba amandla alahleke ngendlela yokushisa, ukunciphisa ukusebenza kakuhle kweenkqubo zombane kunye nezixhobo.
4. Umbane oNcitshisiweyo wangoku: Iingcingo ezixhathisayo zithintela ukuhamba kombane, ezinokuchaphazela ukusebenza kwezixhobo zombane kunye neenkqubo, ngakumbi ezo zifuna amanqanaba aphezulu akhoyo.
5. Ukufudumala kwecandelo: Kwiisekethe ze-elektroniki, ukudibanisa okuphezulu okanye amacandelo angabangela ukufudumeza kwendawo, okuchaphazela ukusebenza kunye nokuthembeka kwesekethe.
Ngokubanzi, iimpembelelo zokuchasana okuphezulu kwiingcingo zixhomekeke kwisicelo esithile kunye nomsebenzi ojoliswe kuwo weingcingo ngaphakathi kwenkqubo.
