Lub tes tsho Quartz yog cov khoom siv tseem ceeb rau cov khoom siv kho dej hauv UV tshuaj tua kab mob. Lub luag haujlwm tseem ceeb yog:
① Tiv thaiv lub teeb ②Ua kom muaj kev sib kis ntawm ultraviolet rays
Lub casing tuaj yeem ntxuav tau ib zaug rau rau lub hlis lossis ib xyoos, thiab nws tuaj yeem ntxuav nrog cov ntaub qhwv nrog dej cawv. Yog tias nws yog qhov qhib channel UV sterilizer lossis UV sterilizer nrog ntau lub teeb, kev ua haujlwm ntawm tus kheej tuaj yeem xaiv.
Quartz iav txhais
Cov khoom siv ntawm lub tes tsho quartz yog quartz iav, uas yog cov khoom siv amorphous nrog ib feem ntawm silicon dioxide. Nws microstructure yog ib qho yooj yim network tsim ntawm silicon dioxide tetrahedral structural units. Vim muaj cov tshuaj lom neeg loj ntawm Si-O, cov qauv yog compact heev, yog li quartz iav muaj cov yam ntxwv tshwj xeeb, tshwj xeeb tshaj yog cov khoom siv kho qhov muag ntawm pob tshab quartz iav yog qhov zoo heev, thiab nws muaj kev xa tawm zoo heev nyob rau hauv qhov kev sib txuas txuas ntxiv ntawm ultraviolet mus rau infrared hluav taws xob.
Quartz iav ua li cas?
Quartz iav yog ua los ntawm ntuj crystalline quartz (crystal los yog ntshiab silica) los yog hluavtaws silane los ntawm melting ntawm kub. Cov khoom melted muaj kev ua tau zoo. Nyob rau hauv ntau dua viscosity ntau, lub raj thiab pas nrig tuaj yeem ua tau thermally zoo li cov iav zoo tib yam, thiab kev ua haujlwm siab ceev kuj tuaj yeem nqa nrog cov cuab yeej abrasive ua los ntawm pob zeb diamond lossis silicon carbide. Kev ua haujlwm, thiaj li ua kom muaj ntau yam duab ntawm cov cuab yeej thiab cov khoom tshwj xeeb.
Kev ua tau zoo ntawm quartz iav feem ntau yog nyob ntawm nws cov purity, ua raws li cov txheej txheem los yog thermal system. Lub hav zoov ntawm kab impurities yuav muaj kev cuam tshuam loj rau kev ua haujlwm ntawm quartz iav; nyob rau tib lub sijhawm, vim qhov kev tsis saib xyuas me ntsis ntawm cov txheej txheem thev naus laus zis lossis cov txheej txheem thermal, nws yuav ua rau muaj ntau yam tsis zoo rau cov tsos zoo, uas ua rau muaj ntau cov khoom pov tseg.
Hauv cov ntsiab lus, cov txheej txheem ua haujlwm ntawm lub tes tsho quartz yog qhov nyuaj, lub nozzle yuav tsum tau muab tshem tawm thiab hlawv, thiab quartz yog qhov tsis yooj yim, yog li tus nqi kuj tseem siab.
Dab tsi yog cov yam ntxwv ntawm quartz iav raj
1. Kub kub tsis kam
Lub softening point kub ntawm quartz iav yog hais txog 1730 degree, nws yuav siv tau rau lub sij hawm ntev ntawm 1100 degree, thiab qhov kub thiab txias yuav siab li 1450 degree rau ib lub sij hawm luv luv.
2. Corrosion kuj
Tsuas yog hydrofluoric acid, quartz iav tsis tshua muaj kev cuam tshuam nrog lwm cov kua qaub, nws cov tshuaj tiv thaiv acid yog 30 npaug ntawm cov ceramics thiab 150 npaug ntawm cov hlau tsis muaj steel, tshwj xeeb tshaj yog nws cov tshuaj stability ntawm qhov kub thiab txias, uas yog unmatched los ntawm lwm yam khoom siv engineering.
3. Zoo thermal stability
Quartz iav muaj cov thermal expansion coefficient me me thiab tuaj yeem tiv taus qhov kub thiab txias hloov. Quartz iav yog rhuab mus txog 1100 degree, thiab nws yuav tsis tawg rau hauv ib txwm kub dej.
4. Lub teeb kis tau tus mob zoo
Quartz iav muaj lub teeb pom kev zoo nyob rau hauv tag nrho cov spectral band los ntawm ultraviolet mus rau infrared, thiab transmittance ntawm lub teeb pom kev yog siab tshaj 95 feem pua, tshwj xeeb tshaj yog nyob rau hauv lub ultraviolet spectral cheeb tsam, lub transmittance mus txog saum toj no 80 feem pua.
Vim li cas quartz tuaj yeem siv ua iav kho qhov muag
Quartz iav muaj nws qhov tshwj xeeb kho qhov muag. Nws muaj peev xwm kis tau deb ntawm ultraviolet spectrum, uas yog zoo dua li tag nrho cov ultraviolet transmitting ntaub ntawv, thiab muaj peev xwm kis tau pom lub teeb thiab nyob ze infrared spectrum. Cov neeg siv tuaj yeem xaiv txhua yam uas xav tau los ntawm 185-3500mμ band ntau raws li lawv xav tau. Vim tias quartz iav muaj qhov kub thiab txias, me me thermal expansion coefficient, zoo tshuaj thermal stability, npuas, kab txaij, uniformity, thiab birefringence piv rau cov iav kho qhov muag, nws yog ib qho kev ruaj khov kho qhov muag uas ua haujlwm nyob rau hauv ntau lub sijhawm hnyav.
