Xa ufuna into ethatha indawo yeucingo lwe-nichrome, kubalulekile ukuqwalasela iimpawu eziphambili ezenza i-nichrome ibe yinto ebalulekileyo: ukumelana nobushushu obuphezulu, ukumelana nombane rhoqo, ukumelana nokugqwala, kunye nokuqina. Nangona izinto ezininzi zisondela, akukho nanye ehambelana nokulinganisela ukusebenza kwe-nichrome—okwenza iimveliso zethu ze-nichrome wire zibe lukhetho oluthembekileyo kwizicelo ezibalulekileyo.
Enye indlela eqhelekileyo yi-kanthal wire,i-iron-chromium-aluminium alloyI-Kanthal igqwesile kwiindawo ezinobushushu obuphezulu, imelana nobushushu obufikelela kwi-1,400°C, obuphezulu kunezinye ii-nichrome grades. Nangona kunjalo, ithambile kwaye ayiguquguquki kangako, nto leyo eyenza kube nzima ukuyibumba ibe yimizobo entsonkothileyo. Kwizicelo ezifuna ukuguquguquka, njengezinto ezincinci zokufudumeza kwi-elektroniki, i-kanthal idla ngokungaphumeleli, ngelixa i-nichrome's ductility ivumela ukwakheka ngokuchanekileyo ngaphandle kokuqhekeka.
Ucingo lweCopper-nickel (Cu-Ni) lolunye uhlobo olukhuphisanayo, oluxatyiswayo ngenxa yokumelana kwayo nokugqwala kunye nokumelana kwayo okuphakathi. Kodwa iCu-Ni iyasokola kumaqondo obushushu aphezulu, ikhupha i-oxidation ngokukhawuleza ngaphezu kwama-300°C, nto leyo ethintela ukusetyenziswa kwayo kwiimeko zobushushu obuphezulu ezifana nee-ovens zoshishino okanye ii-heating coils. INichrome, ngokwahlukileyo, igcina uzinzo nokuba ikwi-1,200°C, nto leyo eyenza ukuba ibe lula kakhulu kwimisebenzi yobushushu obuphezulu.
Ucingo lweTungsten lubonelela ngokumelana nobushushu ngendlela engaqhelekanga, lunyamezela amaqondo obushushu agqithisileyo ukuya kuthi ga kwi-3,422°C. Nangona kunjalo, lubuthathaka kakhulu kwaye alunamandla ombane aphantsi, nto leyo efuna amandla aphezulu ombane ukuze luvelise ubushushu. Oku kwenza kube nzima kwiindawo ezininzi zokufudumeza apho ukusebenza kakuhle kwamandla kunye nokulula kokusetyenziswa kubalulekile—indawo apho i-nichrome, enokumelana kwayo okufanelekileyo kunye nokusebenza kakuhle, ikhanya khona.
Ucingo lwentsimbi engagqwaliyo ludla ngokujongwa ngokuba lufikeleleka lula kwaye lunokumelana nokugqwala. Sekunjalo, lunokumelana okuphantsi kune-nichrome, oko kuthetha ukuba luvelisa ubushushu obuncinci ngobude beyunithi nganye, nto leyo edinga iigeyiji ezityebileyo okanye iivolthi eziphezulu ukuze zilingane nemveliso ye-nichrome. Ngokuhamba kwexesha, intsimbi engagqwaliyo ikwathanda ukuguquka xa ishushu ixesha elide, nto leyo enciphisa ubomi bayo xa kuthelekiswa nokuzinza kwexesha elide kwe-nichrome.
Iimveliso zethu ze-nichrome wire zijongana nale mida yezinto ezithatha indawo yazo. Zifumaneka kwiindidi ezahlukeneyo (ezifanaI-NiCr 80/20), zibonelela ngokuchaneka okuchanekileyo kokukhupha ubushushu rhoqo, ukuguquguquka okugqwesileyo kokwenziwa lula, kunye nokumelana okuphezulu kwe-oxidation kumaqondo obushushu aphezulu. Nokuba zezokufudumeza izinto kwizixhobo, izixhobo zelebhu, okanye kwiifeni zoshishino, ucingo lwethu lwe-nichrome lubonelela ngokusebenza okuthembekileyo, ukusebenza kakuhle kwamandla, kunye nokuqina okunzima ukukuphinda-phinda kwezinye iindlela.
Ukukhetha ucingo olufanelekileyo kuthetha ukubeka phambili umxube owahlukileyo weempawu ezibonelelwa yi-nichrome kuphela. Iimveliso zethu zenzelwe ukuhlangabezana nemigangatho engqongqo yomgangatho, ukuqinisekisa ukuba zingcono kunezinye ezithatha indawo yokusebenza kunye nexesha elide—oko kuzenza zibe lukhetho olukrelekrele kwiimfuno zakho zokufudumeza.
