Daim ntawv thov teb thiab qhov zoo ntawm quartz raj
Quartz iav raj yog ib qho tshwj xeeb kev lag luam iav iav ua los ntawm silica, uas yog cov khoom siv yooj yim heev. Quartz iav raj muaj cov khoom zoo ntawm lub cev thiab tshuaj lom neeg: kub tsis kam, corrosion kuj, thermal stability, zoo lub teeb kis tau tus mob, zoo hluav taws xob rwb thaiv tsev kev ua tau zoo, thiab lwm yam. Nws yog dav siv nyob rau hauv ntau yam xws li hluav taws xob lub teeb qhov chaw, semiconductor, kho qhov muag kev sib txuas lus, tub rog kev lag luam, metallurgy, tsev cov ntaub ntawv, chemistry, machinery, hluav taws xob, kev tiv thaiv ib puag ncig thiab hais txog.
Quartz raj yog cov khoom zoo thiab tus nqi qis, piv rau cov khoom hauv ntau lub teb chaws. Nws tuaj yeem siv rau cov khoom siv thiab cov khoom siv hauv cov khoom siv hauv ntau yam teeb pom kev zoo, hluav taws xob, lub zog tshiab, semiconductor, xov tooj cua thiab TV thiab lwm cov chaw tsim khoom. Cov khoom tshwj xeeb thiab cov duab tuaj yeem ua raws li cov chaw tsim khoom' s kos duab. Cov khoom siv ntshiab quartz tuaj ntawm Nyiv yog siv. Cov khoom tsim muaj tsawg thermal expansion coefficient, kub tsis kam thiab corrosion kuj, thiab siab lub teeb kis tau tus mob.
Quartz tube khoom feem ntau muaj qhov ua tau zoo kho qhov muag, tuaj yeem nkag mus ntev-ntev ultraviolet rays, thiab muaj peev xwm nkag mus tau zoo heev. Cov neeg siv tuaj yeem xaiv cov khoom uas lawv xav tau los ntawm 185 mm txog 3,500 micrometers. Quartz yog tus cwj pwm los ntawm qhov kub thiab txias tsis kam, tshuaj lom neeg ruaj khov, tsis tshua muaj thermal expansion coefficient, zoo streak thiab npuas birefringence. Nws yog nws ntau qhov zoo uas ua rau nws sawv tawm ntawm nws tus kheej zoo hauv ntau qhov chaw hnyav. Nws cov coefficient ntawm thermal expansion tsuas yog ib-nees nkaum ntawm cov iav zoo tib yam. Nws yog rhuab mus rau ib txhiab ob puas degrees Celsius thiab tam sim ntawd muab tso rau hauv dej txias yam tsis tau tawg. Yog hais tias qhov zoo ntawm cov khoom titanium ntxiv, nws tseem tuaj yeem muab pov rau hauv cov khoom tshwj xeeb - xoom expansion coefficient khoom, uas tuaj yeem siv rau hauv high-end technology, laser technology, astronomical surveying thiab lwm yam.
