Teb tiav: Peb raug nug vim li cas alloy thiaj siv los ua cov coils ntawm hluav taws xob toasters thiab hluav taws xob hlau es tsis txhob siv cov hlau ntshiab. … Yog li, qhov kev tiv thaiv ntawm alloys siab dua cov hlau ntshiab-Alloys tsis yaj yooj yim ntawm qhov kub thiab txias, yog li alloys nyiam dua cov hlau ntshiab.
Vim li cas cov tshuab toasters ua los ntawm cov hlau?
Coils ntawm hluav taws xob toasters thiab hluav taws xob hlau ua los ntawm cov hlau tsis yog cov hlau ntshiab vim yog cov hauv qab no: Qhov kev tiv thaiv ntawm cov hlau yog siab dua cov hlau ntshiabNtawm qhov siab kub, cov alloys tsis oxidize. Alloy tsis yaj yooj yim thiab deformed.
Cov alloys twg siv los ua hluav taws xob hlau thiab toasters?
Fuse hlau feem ntau yog tsim los ntawm alloy ntawm txhuas thiab tinuas muaj qhov ua haujlwm siab thiab qis melting point. Nws txuas nrog hauv koob hauv kev teeb tsa hluav taws xob.
Lub kauj ntawm lub tshuab hluav taws xob yog dab tsi?
Lub kauj ntawm lub tshuab hluav taws xob yog dab tsi? Ib qho hlau siv los ua cov khoom cua sov rau cov khoom siv hluav taws xob cua sov yog nichrome. Nws yog ib qho alloy ntawm npib tsib xee, chromium, thiab qee zaum hlau thiab lwm yam khoom lossis cov khoom siv. Nws yog siv los ua hlau tsis kam.
Yuav siv cov hlau twg los ua hlau?
Ib alloy ntawm npib tsib xee thiab chromium (80% nickel, 20% chromium) yog siv los ua cov khoom cua sov rau cov khoom siv hluav taws xob cua sov yog nichrome.
