Nrog rau txoj kev loj hlob ntawm lub neej niaj hnub, tib neeg lub neej tau inseparable los ntawm kev kis tau tus mob fiber ntau Pib ntsais koj teeb. Tam sim no, cov siv fiber ntau siv los ntawm cov neeg feem ntau quartz glas -s fiber.Qhov ntsiab ntau hom ntawm hom khob iav yog ua rau lub siab tawv purity mus rau hauv lub siab-ua rau purity quartz iav rau hauv ib lub cev rau hauv qhov cub kub, thiab rub tawm cov ntsev ntawm lub khob ntawm 100m. Thaum lub teeb ci ntsa rau ntawm txoj cai rau hauv lub khob iav, lub teeb ci mus raws li iav fiber, yog li nws yog hu ua fiber ntau qhov fiber.In 1966, british bor -n Suav kws tshawb fawb Charles Kao tau ua tim khawv cov feasibility ntawm siv optical fiber li nruab nrab kom paub optical kis hluav taws xob.Now, cov iav optical raws li tus nruab nrab kom paub optical transmissio n teeb liab.Now, optical fiber ntau los ua ib tug dav siv kev sib txuas lus khoom.
Lub teeb ntsig txog iav thiab thaij iav thaij iav thiab thaij iav thaij iav thiab thaij iav thaij iav hauv iav thiab thaij iav thaij iav hauv cov duab tshav ntuj los yog cov teeb pom kev zoo, los ntawm colour -rless pob tshab xeev hauv tsaus; xim hloov yog tias cov iav yog xyaw wi-nyiaj nyiaj bromide (los yog silver chloride) thiab ib qho me me ntawm tooj liab oxide.Under muaj zog lub teeb irradiation,
(bromine) yuav ua rau cov hlau nplaum thiab bromine atoms (los yog chlorine ato-ms), thaum lub xauv nyiaj yuav nqus pom qhov kaj. Thaum qhov nyiaj ntawm cov nyiaj hauv cov nyiaj ua tau zoo tuaj, muaj ntau qhov pom ntawm lub khob iav tsis yog yuav nqus tau, thiab lub khob yuav tshwm ntsej muag thiab dub. Thaum lub iav blackened muab tso rau hauv maub, qhov nyiaj atoms thiab bromine (los yog chlorin -e) atoms, catalyzed los ntawm tooj liab oxide, ua ke rau daim nyiaj dawb bromide (los yog Cov tshuaj chloride dawb, thiab cov iav b-nce tsis muaj xim thiab pob tshab dua tshiab.Photochromic iav yog siv los ua ib lub lens rau cov xim hloov xim, thiab siv tau los ua qhov rais kom yoojyim rau hnub ci uas nkag mus rau hauv chav nyob rau hauv lub caij ntuj sov. Xyoo tsis ntev los no, electrochromic iav, ib hom tshiab ntawm cov xim hloov iav uas tuaj yeem hloov xim steadi ly thiab reversibly nyob rau hauv qhov kev txiav txim ntawm cov hluav taws xob, tau tshwm sim los ntawm.Cov iav tau hloov colour unde -r neeg tswj.Yog muaj cov vaj tse uas siv cov electrochromic iav ua los ntawm gla ss ntaub thaiv phab ntsa.
Lwm hom iav yog qhov tseem ceeb hauv peb lub neej, uas yog siab borosilicate iav.Koj yuav tsis paub txog lub npe ntawm lub khob no, tab sis cov tais diav uas peb siv txhua hnub yog lub khob khob uas tib neeg tuaj koom.
Piv nrog rau iav zoo tib yam, high borosilicate iav muaj qhov zoo ntawm kev kub siab-qhov siab, nce qib tsawg, siab zog thiab siab tawv.
Yog li ntawd, lub khob dej ua los ntawm high borosilicate iav tsis yog yooj yim mus ua txhaum nyob rau hauv cov ntaub ntawv ntawm Sudden txias thiab kub. Ntxiv rau hauv, lub ntsiab khoom rau ua lub khob iav yog borosilicate iav.
