Cov hlab ntawm tubular infrared tawg qhov chaw yog ua los ntawm quartz iav

Lub tshuab hluav taws xob hluav taws xob hluav taws xob yog qhov tshwj xeeb ntawm cov cua sov ua kom sov, uas siv cov ntaub ntawv xws li tungsten, hlau npib tsib xee, lossis npib tsib xee chromium alloy ua cov hluav taws xob los tsim cov hluav taws xob hluav taws xob. Tom qab siv lub tshuab hluav taws xob, thermal tawg yog tsim los ntawm nws cov cua sov ua haujlwm. Feem ntau siv hluav taws xob hluav taws xob hluav taws xob hluav taws xob hluav taws xob muaj xws li lub teeb hom (reflective), raj hom (quartz raj hom), thiab phaj hom (planar). Lub teeb hom yog lub teeb infrared uas siv tungsten xaim raws li cov emitter thiab muab ntim rau hauv lub khob iav uas muaj roj inert, zoo ib yam li lub teeb pom kev zoo. Tom qab tau hluav taws xob, lub tshuab hluav taws xob tsim hluav taws xob tsim hluav taws xob (ntawm qhov kub qis dua li lub teeb pom kev zoo), yog li emitting ib tug loj npaum li cas ntawm infrared tawg nrog ib tug wavelength ntawm txog 1.2 micrometers. Yog hais tias ib txheej txheej txheej yog coated rau ntawm phab ntsa sab hauv ntawm lub iav plhaub, cov hluav taws xob infrared tuaj yeem ua kom pom tseeb hauv ib qho kev taw qhia, yog li lub teeb hom hluav taws xob hluav taws xob hluav taws xob tseem hu ua lub teeb hluav taws xob infrared radiator. Lub raj ntawm lub raj hom infrared hluav taws xob qhov chaw yog ua los ntawm quartz iav nrog tungsten hlau nyob rau hauv nruab nrab, yog li nws tseem hu ua quartz raj hom infrared radiator. Lub wavelength ntawm infrared emissions los ntawm lub teeb thiab raj hom yog nyob ntawm 0.7 mus rau 3 microns, thiab lawv ua hauj lwm kub kuj yog tsawg. Lawv feem ntau yog siv rau cua sov, ci, ziab, thiab infrared kho nyob rau hauv lub teeb thiab textile industries, raws li zoo raws li nyob rau hauv daim ntawv thov kev kho mob. Cov nplaim hluav taws xob ntawm cov phaj hom infrared hluav taws xob qhov chaw yog ib qho chaw tiaj tus uas muaj cov phaj tsis sib haum. Lub pem hauv ntej ntawm lub phaj tiv thaiv yog coated nrog cov ntaub ntawv uas muaj siab reflection coefficients, thiab sab nraub qaum yog coated nrog cov ntaub ntawv uas tsis tshua muaj reflection coefficients, yog li feem ntau ntawm cov tshav kub lub zog yog radiated los ntawm pem hauv ntej. Kev ua haujlwm kub ntawm lub phaj tuaj yeem ncav cuag tshaj 1000 degree thiab tuaj yeem siv rau kev sib tsoo ntawm cov khoom siv hlau, cov kav dej loj, thiab cov thawv ntim khoom.

Vim nws muaj peev xwm nkag mus tau zoo, cov hluav taws xob infrared tau yooj yim absorbed los ntawm cov khoom, thiab ib zaug absorbed los ntawm cov khoom, nws tam sim ntawd transforms rau hauv thermal zog; Daim ntawv thov ntawm cov cua sov infrared tau tsim sai heev vim nws tsis tshua muaj zog poob ua ntej thiab tom qab cua sov, yooj yim tswj kub, thiab cua kub zoo.

Nruab nrab cua sov

Siv high-frequency hluav taws xob teb rau tshav kub rwb thaiv tsev cov ntaub ntawv. Cov khoom cua kub tseem ceeb yog dielectric. Thaum lub dielectric muab tso rau hauv ib qho kev hloov hluav taws xob, nws yuav rov qab polarized (ib qho tshwm sim uas qhov sib npaug ntawm qhov sib npaug ntawm cov nqi hluav taws xob tshwm sim ntawm qhov chaw lossis sab hauv ntawm dielectric nyob rau hauv qhov kev txiav txim ntawm hluav taws xob teb), yog li hloov hluav taws xob hluav taws xob. nyob rau hauv hluav taws xob teb rau hauv thermal zog.

Qhov hluav taws xob teb zaus siv rau nruab nrab cua sov yog siab heev. Nyob rau hauv nruab nrab, luv luv, thiab ultra luv yoj bands, zaus ntawm ob peb puas kHz mus rau 300 MHz yog hu ua high-frequency medium cua sov. Yog hais tias qhov zaus tshaj 300 MHz thiab ncav cuag lub microwave band, nws yog hu ua microwave nruab nrab cua sov. Feem ntau, high-frequency nruab nrab cua sov yog nqa tawm nyob rau hauv hluav taws xob teb ntawm ob daim hlau; Microwave nruab nrab cua sov yog nqa tawm nyob rau hauv cov hluav taws xob teb ntawm waveguides, resonant kab noj hniav, los yog microwave antennas.
