Tshwj xeeb yuav tsum tau them nyiaj rau kev siv quartz iav raj
Quartz iav raj yog cais raws li cov khoom tawg yooj yim. Kev saib xyuas tshwj xeeb yuav tsum tau them thaum siv lawv. Dab tsi yog kev ceev faj rau kev siv quartz tubes kom ntxaws? Quartz raj yog ib qho yooj yim tawg, yog li tuav nrog kev saib xyuas thaum xaiv kom tsis txhob tawg vim kov. Txawm hais tias nws muaj qhov ua kom sov zoo, nws yuav tsum xav txog nws qhov kev nthuav dav coefficient thaum siv nrog lwm cov ntaub ntawv, txwv tsis pub nws yuav puas.
Qhov tseem ceeb tshaj plaws thiab cov khoom siv raw ntawm quartz iav raj yog quartz raj. Nws tau nkag siab tias quartz raj yog ib qho khoom siv silica iav, uas feem ntau muab faib ua ob pawg: pob tshab quartz raj thiab opaque quartz raj (fused silica). Lub pob tshab quartz raj tsuas muaj ob peb npuas xwb, thiab muaj qhov zoo sib xws ntawm qhov muag pom thiab pob tshab. Nws yog tsim los ntawm siv lead ua los yog silicon tetrachloride ua raw cov ntaub ntawv thiab melted ntawm kub kub. Cov cuab yeej cuab tam ntawm quartz raj zoo dua li cov iav tawv thiab ceramics. Lub taub me me quartz raj thiab cov khoom siv quartz tube tuaj yeem tiv taus siab heev. Yog tias muaj qhov tsis xws li macro hauv cov khoom siv quartz tube, xws li npuas, cov khoom txawv teb chaws, thiab cov melting tsis sib xws Thiab cov kev ntxhov siab uas twb muaj lawm yuav cuam tshuam rau nws lub zog thiab txo nws.
