Lub hom phiaj ntawm tungsten filament yog txuas rau hauv series nrog quartz teeb raj hauv mercury teeb. Lub teeb mercury siv mercury vapor generated thaum mercury tawm mus kom pom lub teeb pom kev raws li lub teeb hluav taws xob. Lub teeb mercury tuaj yeem muab faib ua peb hom: lub teeb muaj mercury uas tsis tshua muaj siab, lub teeb muaj mercury siab thiab ultra-siab mercury teeb. Thaum lub teeb hluav taws xob mercury uas tsis tshua muaj hluav taws kub kub, qhov mercury vapor siab tsawg dua ib qho chaw. Nyob rau lub sijhawm no, mercury atoms feem ntau radiate ultraviolet lub teeb nrog lub wavelength ntawm 253.7nm.
Thaum tungsten hlau yog siv nyob rau hauv lub high-pressure mercury teeb, lub puab phab ntsa ntawm lub iav plhaub yog tsis coated nrog phosphor, tab sis ib tug tungsten hlau txuas nyob rau hauv series ntawm lub plhaub thiab lub quartz teeb. ntawm lub teeb liab los txhim kho lub teeb xim. Hom hluav taws xob siab hluav taws xob hluav taws xob mercury teeb no yooj yim siv thiab tuaj yeem txuas ncaj qha mus rau 220-volt AC fais fab mov. Nws cov luminous efficiency yog qis dua li ntawm high-voltage fluorescent mercury teeb, tab sis siab dua li ntawm lub teeb incandescent. Lub hauv paus ntawm lub teeb yog lub raj xa tawm, uas yog ua los ntawm quartz iav. Lub raj yog sau nrog ib qho nyiaj mercury thiab argon. Tungsten yog siv los ua lub ntsiab electrode thiab ntim nrog alkaline ntiaj teb hlau oxide electron-emitting cov ntaub ntawv. Cov electrode thiab quartz iav yog hermetically kaw nrog molybdenum ntawv ci. Feem ntau, ib qho kev pabcuam electrode yog siv rau kev pib, uas txuas nrog lub electrode uas tsis nyob ib sab los ntawm ib qho 40-60κΩ resistor. Ntxiv nrog rau nws txoj haujlwm tiv thaiv, lub qhov rooj sab nrauv tseem tiv thaiv ib puag ncig los ntawm kev cuam tshuam lub teeb.
Cov kev ceev faj
Txoj kev khaws cia: Khaws rau hauv qhov chaw txias thiab kaw, kom deb ntawm tshav ntuj ncaj qha.
1. Transformers thiab capacitors ntawm cov lus qhia tshwj xeeb yuav tsum tau nruab thaum siv;
2. Ua ntej siv, qhov saum npoo ntawm lub teeb yuav tsum tau muab ntxuav kom huv nrog ethanol, thiab nws yog nruj me ntsis txwv tsis pub kov nws ncaj qha nrog koj txhais tes;
3. Lub teeb ua kom muaj zog ntev-yoj violet hluav taws xob (lub ntsiab wavelength yog 365 nanometers) los ntawm high-pressure mercury vapor discharge;
4. Muaj zog ultraviolet rays tuaj yeem hlawv qhov muag thiab tawv nqaij, yog li yuav tsum tsis txhob cuam tshuam lub teeb ncaj qha thaum siv;
5. Lub teeb yuav raug puas tsuaj, ua rau lub emission ntawm mercury vapor. Cov neeg ua haujlwm hauv tsev yuav tsum tawm tam sim ntawd thiab tso cai rau lub xaib txuas ntxiv ua pa rau 20-30 feeb kom tiv thaiv cov pa mercury los ntawm kev nqus mus rau hauv lub cev thiab ua rau muaj tshuaj lom. Thaum nws muaj kev nyab xeeb, lub xaib yuav tsum tau muab ntxuav kom huv si raws sijhawm, thiab cov khoom siv mercury uas siv tau tuaj yeem khaws cia rau kev sim.
