Dab tsi yog cov cua kub muaj peev xwm ntawm txhuas oxide (al2o3)? Cov kev nkag siab tseem ceeb rau cov ntawv thov kub
Tso lus
Cov khoom siv muaj cua sov ntawm txhuas oxide (al2o3) yog cov ntaub ntawv siv kub uas tau ua tiav, cov kev kub ntxhov ntawm cov khoom siv kub ua haujlwm ntawm lub zog thaum tshav kub kub hloov, ua rau nws haum rau cov ntawv thov uas xav tau cov khoom siv hluav taws xob kub thiab kub, thiab cov khoom kub thiab kub, ua rau nws muaj cov khoom muaj peev xwm rau cov khoom muaj chaw lag luam.
Cov Ntsiab Lus Tseem Ceeb:
Dab tsi yog cov cua kub muaj peev xwm ntawm txhuas oxide (al2o3)? Cov kev nkag siab tseem ceeb rau cov ntawv thov kub
Lub ntsiab lus ntawm kev kub muaj peev xwm:
Muaj peev xwm ua kom sov yog qhov ntau npaum li cas ntawm cov cua sov yuav tsum tau kom nce qhov kub ntawm aluminium no yog 0880 J ntawm lub zog kom nce qhov kub ntawm 1 grec ntawm txhuas oxide los ntawm 1℃Celsius.
Qhov tseem ceeb ntawm Alumina Tshav Kub Kub:
Qhov kub muaj peev xwm ntawm alumina yog qhov tseem ceeb rau nws cov kev ua tau zoo hauv kev siv hluav taws xob kom haum Alumina thiab cov cua sov tsis haum thiab cua sov tsis kam .
Sib piv nrog lwm cov khoom:
Cov muaj peev xwm ua kom sov ntawm Alumina ua haujlwm tau ua ke nrog nws lwm cov khoom, xws li
Thermal conductivity (25 . 0 w / mk): Facilitates Kub Hloov Hloov Hloov.
Kev kub siab kuj: tuaj yeem siv rau hauv ib puag ncig mus txog 2000℃.
Hnav thiab corrosion Kuj: ua kom muaj kev cuam tshuam tsis tu ncua nyob rau hauv kev mob hnyav .
Muaj Ntaub Ntawv:
Kev sib xyaw ntawm kev kub muaj peev xwm thiab lwm yam khoom ua rau Alumina ib cov ntaub ntawv zoo rau cov crucaibles thiab cov txheej txheem rauv taws nrog cov txheej txheem kub:
Crucibles thiab cov cub ntaub hauv cov txheej txheem kub siab .
Cov tshuaj insulators hluav taws xob nyob rau hauv cov ntaub ntawv muaj zog siab .
Hnav-resistant seem hauv cov cuab yeej siv tshuaj lom neeg thiab cov khoom siv tshuaj lom .
Cov tswv yim cuam tshuam rau cov khoom siv yuav khoom:
Thaum xaiv cov cuab yeej Alumina lossis cov khoom siv, xav txog
Kev ua haujlwm ntsuas kub thiab nqus kub .
Cov tseev kom muaj rau kev ruaj khov ruaj khov thiab thermal poob siab kuj .
Kev sib raug zoo nrog lwm cov ntaub ntawv thiab ib puag ncig cov mob .
Txwv thiab kev txiav txim siab:
Thaum Alumina muaj cov khoom siv kub zoo heev, nws muaj qhov kev xaiv loj me me piv tau piv rau cov ntawv thov uas yuav tsum tau hloov kho kub heev los yog kub ceev.
Los ntawm kev nkag siab Alumina cov kev muaj peev xwm ua kom sov thiab nws li cas nws cuam tshuam nrog txiav txim siab txog seb nws puas tsim nyog rau ib qho applicate .
