Thermal stability ntawm iav dropper fwj yog ib qho ntawm cov khoom tseem ceeb

Cov cuab yeej ntawm cov iav dropper lub raj mis kom tsis txhob raug rhuav tshem los ntawm qhov kub thiab txias hloov pauv ua lub thermal stability ntawm lub iav dropper lub raj mis, uas yog, tsis kam mus quenching thiab kub. Lub thermal stability ntawm lub iav dropper lub raj mis yog qhia raws li qhov kub ntawm qhov sib txawv uas lub iav dropper lub raj mis tuaj yeem tiv taus thaum tsis muaj kev puas tsuaj. Lub raj mis manufacturers hais tias thermal stability ntawm iav fwj yog ib qho tseem ceeb ntawm cov iav. Yog li ntawd, nyob rau hauv kev tshawb fawb thiab zus tau tej cov iav fwj manufacturers, feem ntau iav fwj yog kuaj rau cov cuab yeej no, tshwj xeeb tshaj yog nyob rau hauv lub thermal ua ntawm iav, nws yog ib qho tseem ceeb tshwj xeeb los txiav txim siab thermal stability ntawm iav fwj. Kev txiav txim siab ntawm cov cuab yeej no yog kev txiav txim siab rau kev tsim cov iav dropper fwj thiab yog ib txoj haujlwm tseem ceeb.

Lub thermal conductivity ntawm iav fwj tsis zoo heev, tshwj xeeb tshaj yog cov iav fwj nyob rau hauv lub tsev xog paj, uas yog nyob rau hauv lub zos rhuab thiab lub tshav kub hloov yog qeeb heev. Cov cheeb tsam no yog nquag overheating. Thaum overheated rau ib qho twg, muaj peev xwm ua rau tawg vim qhov tsis sib xws thiab cua sov ntawm lub raj mis iav. Cov khoom siv ntawm lub khob iav tsis zoo li cov khoom siv thermal conductivity, uas muaj thermal conductivity zoo. Piv txwv li, cov khoom siv hlau muaj cov thermal conductivity zoo, txawm tias nyob hauv cov cua sov ntawm cov khoom siv hlau.

Lub tshav kub conduction ceev ntawm cov ntaub ntawv hlau yog ceev, lub zos overheating tshwm sim ploj sai sai, thiab thermal conductivity ntawm cov ntaub ntawv hlau yog muaj zog tshaj li cov iav ntaub ntawv. Lub peev xwm ntawm ib yam khoom los hloov thermal zog kom qis dua qhov kub ntawm qhov kev co yog hu ua thermal conductivity. Lub thermal conductivity ntawm ntau yam khoom yog sawv cev los ntawm thermal conductivity.

Txij li cov iav hlau yog txawv ntawm lub khob iav nrog nws tus lej electron sib raug thiab cov qauv tsis zoo, cov thermal conductivity ntawm lub khob iav uas ua rau cov thermal kuj nce qis dua. Vim lub pob tshab ntawm lub khob thiab qhov nce permeability ntawm radiant tshav kub, thermal conductivity ntawm lub iav fwj nce nrog qhov nce ntawm qhov kub ntawm qhov kub thiab txias. Xws li lub khob iav rhuab mus rau qhov muag kub ntawm lub khob ntawm chav tsev kub yog yuav luag ob npaug los ntawm cov cua sov, lwm qhov piv txwv ntawm cov iav pob tshab yog piv rau cov iav tinted molten, thermal conductivity ntawm lub qub yog siab dua li yav tas los, nyob rau hauv zus tau tej cov iav, tshwj xeeb tshaj yog iav Melting crucible furnaces, nyob rau tib lub kub, thiab ntawm tib yam muaj pes tsawg leeg, feem ntau nyuaj tshaj li melting pob tshab iav fwj, vim hais tias cov thermal conductivity yog tsawg tshaj li cov pob tshab xim iav fwj.
