Kev piav qhia
Cov hluav taws xob cua sov hlau yuav tsum muaj qhov tsim nyog resistivity thiaj li ua tiav lub hom phiaj ntawm cua sov thaum siv hluav taws xob. Yog hais tias lub resistivity siab dhau los yog tsawg dhau, luv luv los yog ntev heev, yuav tsum tau nyias nyias los yog tuab heev cua sov xov hlau. Qhov no ua rau muaj teeb meem hauv kev tsim khoom. Lub melting point yuav tsum kuj siab, thiaj li hais tias nws yuav tsis yaj thaum nws nres cua sov; Nyob rau hauv qhov kub thiab txias, cov tshuaj stability yuav tsum kuj siab, thiaj li hais tias nws tsis oxidize sai thiab muaj ib tug ntev lifespan.
Thaum qhov hluav taws xob tsis tu ncua, raws li qhov kub thiab txias, 0.5 hli Heating Resistance Nichrome Hlau yuav nce thiab lub zog yuav txo qis me ntsis. Thaum cov cua sov tsim thiab cov cua kub dissipation ncav cuag qhov sib npaug, qhov kub yuav ruaj khov. Lub zog ntawm Nichrome hlau yog txiav txim siab los ntawm cov khoom siv, thickness thiab ntev. Yog tias nws yog cov khoom siv tib yam, qhov ntev thiab thinner lub cua sov hlau yog, qhov ntau dua qhov tsis kam yuav thiab lub zog me dua.
0.5mm cua sov tsis kam nichrome hlau yog cov khoom siv hluav taws xob uas hloov hluav taws xob rau hauv lub zog sab hauv. Feem ntau hais lus, qhov tsis kam ntawm cov hlau nce nrog qhov kub thiab txias.Nickel chromium hlau muaj cov yam ntxwv ntawm weldability, siab hluav taws xob conductivity, haum linear expansion coefficient, muaj zog zoo ntawm kub kub, tsis tshua muaj resistivity. Nrog siab melting point, corrosion kuj, zoo mechanical zog.
Lub hwj chim teeb ntawm 0.5 hli cua sov tsis kam nichrome hlau yog qhov ntau dua lub zog, qhov me dua tag nrho cov kev tiv thaiv.Cov nickel chromium cua sov hlau resistivity muaj ntau yam, yog tias cov resistivity loj dhau los yog me me, nws xav tau luv luv los yog ntev heev, nyias nyias los yog tuab heev nickel chromium hlau, yog li nws nyuaj rau tsim thiab siv lub tshuab hluav taws xob sib txawv.
Ib qho tseem ceeb parameter ntawm nickel chromium cua sov hlau yog lub zog saum npoo. Lub resistivity loj dhau lawm, los ntawm ib qho tam sim no, lub zog saum npoo kuj loj. Yog li cov khoom siv hluav taws xob ntawm lub zog me me, xaiv cov kab me me me me tam sim no, tab sis qhov loj ntawm tam sim no txiav txim siab ntawm qhov loj ntawm qhov tsis kam, qhov ntev ntawm cov hluav taws xob cua sov thiab txoj kab uas hla yog xam.
Txawm li cas los xij, nws yuav tsum raug sau tseg tias kev tsim cov nickel -chromium alloy cua sov xov hlau yuav tsum tau siv cov nickel. Tus nqi ntawm cov hlau no siab dua cov hlau, chromium thiab txhuas. Yog li ntawd, cov nqi tsim khoom ntawm nickel-chromium alloy cua sov hlau yog qhov siab, uas tsis tsim nyog rau kev tswj hwm tus nqi.
