Muaj pes tsawg degrees qhov kub ntawm cov cua sov xaim thaum ua haujlwm?
Lub npe tseeb ntawm cov cua sov hlau yuav tsum raug hu ua cov hlau tsis muaj zog, uas yog cov hlau ua los ntawm cov hlau sib xyaw nrog npib tsib xee, chromium, tungsten thiab lwm yam hlau, thiab yuav kub hnyiab tau vim muaj kev tiv thaiv thaum siv hluav taws xob.
Cov hlau tiv thaiv yeej tsis hloov qis dua 200 degrees Celsius, tab sis nws yuav tshwm dawb vim yog cov dej ntws tawm ntawm qhov chaw.
Thaum 200-400 degrees Celsius, cov hlau tsis kam yuav pib blush.
Ntawm 400-700 degrees Celsius, cov filament kuj yuav dub me ntsis vim oxidation nto, thiab maj mam ci thiab tig liab.
Ntawm 700-1400 degrees Celsius, cov filament kuj yuav pib emit ib tug muaj zog ci, thiab xim yuav maj mam hloov los ntawm tsaus liab mus rau txiv kab ntxwv-dawb.
Tshaj li 1400 degrees, feem ntau cov hlau tsis kam yuav yaj los yog hlawv thiab evaporate.
Yog tias nws yog tungsten alloy, nws tuaj yeem ncav cuag li 3000 degrees thaum tsis muaj huab cua, thiab lub sijhawm no, nws yuav emit kub txiv kab ntxwv-dawb lub teeb.
Tshaj 3000 degrees, tsuas yog cov alloys tshwj xeeb tuaj yeem ua tau, thiab feem ntau tsis muaj leej twg siv lawv li cov xov hlau tiv thaiv.
