Nichrome - Wikipedia
is siv, tsis yog cov hlau ntshiab vim yog cov hauv qab no: (i) Resistivity ntawm Nichrome yog ntau dua piv rau cov hlau ntshiab. (ii) Melting point ntawm Nichrome yog siab piv rau cov hlau ntshiab.
Vim li cas Nichrome siv hauv cov khoom siv hluav taws xob tsim hluav taws xob hloov cov hlau ntshiab?
Nyob rau hauv cov khoom siv hluav taws xob ua kom sov xws li. hlau, hluav taws xob rhaub, boiler, toaster, thiab lwm yam hlau xws li Nichrome yog siv, tsis yog hlau ntshiab. … (2) Ib qho hlau, xws li Nichrome, muaj kev tiv thaiv siab thiab nws tuaj yeem ua kom sov rau qhov kub siab yam tsis muaj oxidation, sib piv rau cov hlau ntshiab.
Nichrome cov cuab yeej siv li cas hauv cov khoom siv hluav taws xob tsim hluav taws xob?
2. Ib qho hlau xws li Nichrome muaj siab tiv taus thiab nws tuaj yeem ua rau kub kub yam tsis muajoxidation hauv qhov sib piv rau cov hlau ntshiab. 3. Yog li ntawd, cov coils hauv cov khoom siv cua sov xws litoaster thiab hluav taws xob hlau yog ua los ntawm cov hlau xws li Nichrome es tsis yog cov hlau ntshiab.
Nichrome puas yog hlau ntshiab?
Nyob rau hauv cov khoom siv hluav taws xob ua kom sov xws li. hlau, hluav taws xob rhaub, boiler, toaster thiab lwm yam, ib tug alloy xws li Nichrome yog siv, tsis ntshiab hlau.
Vim li cas nichrome hlau ua kom sov?
Nichrome vim rau nws qhov kev tiv thaiv siab tsis tso cai rau lub zog hluav taws xob yooj yim hla nws. Qhov hluav taws xob hluav taws xob no hloov mus rau hauv lub zog hluav taws xob. Yog li nichrome hlau tau rhuab nyob rau hauv hluav taws xob Circuit Court.
