Ucingo lwe-Nichrome, i-nickel-chromium alloy (ngokuqhelekileyo i-60-80% ye-nickel, i-10-30% ye-chromium), yimathiriyeli yehashe ebhiyozelwa ngokudityaniswa kwayo okukodwa kozinzo lobushushu obuphezulu, ukumelana nombane okungaguqukiyo, kunye nokumelana nomhlwa. Ezi mpawu ziyenza ibaluleke kakhulu kuwo onke amashishini ahlukeneyo-ukusuka kwizixhobo zasekhaya zemihla ngemihla ukuya kwiisetingi ezifunwa kakhulu kwimizi-mveliso-kwaye iimveliso zethu zocingo lwe-nichrome zenziwe ngobunjineli ukuze zinike ukusebenza okugqibeleleyo kwimeko nganye yokusetyenziswa.
1. Izinto zokufudumeza: Isicelo esingundoqo
Eyona nto ixhaphakileyo yokusetyenziswa kwentambo ye-nichrome ilele ekuveliseni izinto zokufudumeza, ngenxa yokukwazi ukuguqula amandla ombane kubushushu ngokufanelekileyo nangokuthembekileyo. Kwizixhobo zasekhaya, inika amandla iikhoyili zokufudumeza kwi-toaster, izomisi zeenwele, izitovu zombane, kunye nezifudumezi zasemkhathini. Ngokungafaniyo nezinye iintsimbi ezithambisayo okanye ezenza i-oxidize kumaqondo obushushu aphezulu, ucingo lwethu lwe-nichrome lugcina imfezeko yolwakhiwo naxa lufudunyezwa ukuya kuthi ga kwi-1,200°C, luqinisekisa ukuba izixhobo zombane zisebenza ngokungaguqukiyo iminyaka. Umzekelo, iikhoyili zokufudumeza kucingo lwethu lwe-nichrome ziyilwe ngendlela echanekileyo yokuxhathisa (ngokuqhelekileyo yi-1.0-1.5 Ω·mm²/m) ukuhambisa ubushushu obufanayo—akukho ndawo zishushu, ubushushu obuzinzileyo obuphucula ubomi besixhobo.
Kwiimeko zoshishino, ucingo lwe-nichrome luyintsika yeenkqubo zokufudumeza okuphezulu. Isetyenziswa kwiziko lemizi-mveliso yokufakwa kwentsimbi, oomatshini bokubumba iplastiki, kunye nee-oveni zokuphatha ubushushu, apho inyamezela ukuvezwa ixesha elide kubushushu obugqithisileyo ngaphandle kokuthotywa. I-heavy-gauge nichrome wire (i-0.5-5mm ububanzi) ilungiselelwe le misebenzi, kunye nokunyanzeliswa kwe-oxidation eyongeziweyo ukuze imelane nokusebenza okuqhubekayo kwiindawo ezinzima zoshishino.
2. ILebhu kunye neZixhobo zeNzululwazi
Ucingo lwe-Nichrome lusisiseko kwiilabhoratri, apho ukufudumeza ngokuchanekileyo kubalulekile. Isetyenziswa kwizitshisi zeBunsen (njengesixhobo sokufudumeza kwizinto ezahlukeneyo zombane), ukufudumeza iingubo zokufudumeza iflaski, kunye namagumbi alawulwa ngubushushu. I-fine-gauge yethu ye-nichrome wire (i-0.1-0.3mm ububanzi) igqwesa apha-i-ductility yayo ephakamileyo ivumela ukuba ifakwe kwiikhoyili ezincinci, eziyinkimbinkimbi, ngelixa ukuxhatshazwa kwayo okuzinzile kuqinisekisa ukulawulwa kweqondo lokushisa ngokuchanekileyo, kuyimfuneko kwiimvavanyo ezibucayi.
3. Amacandelo okuchasa kunye nezicelo ezikhethekileyo
Ngaphandle kokufudumeza,ucingo lwe-nichromeUkuxhathisa kombane okungaguqukiyo kuyenza ilungele izinto ezichasayo kwizinto zombane, ezifana (izixhasi ezisisigxina) kunye neemitha. Ikwafumana ukusetyenziswa kwiinkalo ezizodwa: kushicilelo lwe-3D, inika amandla iibhedi ezifudumalayo zokubambelela kwi-filament; kwi-aerospace, isetyenziselwa izinto zokufudumeza ezincinci kwi-avionics; nakwiiprojekthi zokuzilibazisa (ezifana neendlela zikaloliwe okanye izifudumezi ze-DIY), ukusetyenziswa kwayo ngokulula kunye nokufikeleleka kwayo kuyenza ibe yintandokazi.
Iimveliso zethu zocingo lwe-nichrome zifumaneka kuluhlu olupheleleyo lwamabanga (kuquka i-NiCr 80/20 kunye ne-NiCr 60/15) kunye neenkcukacha, ukusuka kwiingcingo ezicolekileyo kakhulu ezicetywayo ezicekethekileyo ukuya kwiingcingo ezishinyeneyo zokusetyenziswa kakhulu kwimizi-mveliso. Umqulu ngamnye ufumana uvavanyo olungqongqo lwekhwalithi-kuquka ukuqinisekiswa kokwakheka kwe-alloy kunye nokuhlolwa kwe-resistiveivity-ukuqinisekisa ukuba ihlangabezana nemigangatho yoshishino. Nokuba ufuna into yokufudumeza ethembekileyo yezixhobo zendlu okanye isisombululo esomeleleyo kwiziko lamashishini, ucingo lwethu lwe-nichrome luhambisa ukusebenza, ixesha elide, kunye nokungaguquguquki okudingayo.
