Cov khoom siv thermal feem ntau suav nrog ntau yam: thermal conductivity, thermal stability, thermal expansion, thiab thermal muaj peev xwm.
Thermal conductivity yog hais txog cov khoom muaj peev xwm ua kom sov. Cov khoom sib txawv muaj qhov sib txawv thermal conductivity. Qee cov ntaub ntawv, xws li cov hlau, muaj cov thermal conductivity zoo, sai sai hloov cov cua sov thoob plaws hauv cov khoom thiab ua rau muaj qhov sib txawv ntawm qhov kub thiab txias. Hauv qhov sib piv, qee qhov tsis yog -hlau thiab cov khoom sib xyaw muaj cov thermal conductivity tsis zoo, ua rau qeeb dua cov cua sov.
Thermal stability yog hais txog cov khoom muaj peev xwm tiv thaiv thermal deformation thiab kev puas tsuaj ntawm qhov kub thiab txias. Zoo thermal stability txhais tau hais tias cov khoom muaj peev xwm tswj tau nws cov khoom ntawm qhov kub thiab txias thiab yuav tsis yooj yim decompose, oxidize, los yog deteriorate vim kub nce. Cov cuab yeej no yog qhov tseem ceeb rau cov khoom siv thiab cov khoom siv ua haujlwm hauv siab - qhov kub thiab txias.
Thermal expansion yog hais txog cov cuab yeej ntawm ib yam khoom kom loj tuaj thaum rhuab. Cov ntaub ntawv feem ntau nthuav mus rau qee qhov thaum rhuab, tab sis qib ntawm kev nthuav dav txawv ntawm cov khoom sib txawv. Cov cuab yeej no tseem ceeb heev rau kev tsim thiab tsim cov tshuab precision thiab cov cuab yeej siv, yuav tsum tau xav txog qhov cuam tshuam ntawm qhov kub thiab txias ntawm qhov ntev.
Thermal peev yog hais txog cov khoom muaj peev xwm nqus los yog tso cua sov. Cov khoom siv thermal muaj peev xwm txiav txim siab tus nqi thiab qhov twg ntawm nws qhov kub hloov pauv. Cov ntaub ntawv uas muaj peev xwm ua kom muaj cua sov tuaj yeem nqus tau cov cua sov sai dua, ua rau tus nqi qis thaum kub nce lossis poob. Qhov no yog qhov tseem ceeb heev rau kev tswj qhov kub thiab txias ntawm cov khoom siv lossis cov tshuab.
