Dab tsi yog cov khoom siv hluav taws xob rwb thaiv tsev refractory?Cov kev cai dav dav ntawm cov cuab yeej siv hluav taws xob thiab cov kav dej rwb thaiv tsev, cov khoom siv hluav taws xob thermal txhais tau hais tias thaum qhov nruab nrab kub sib npaug los yog tsawg dua 623K (350 ° C), cov thermal conductivity tsawg dua 0. 14W / (mK) cov khoom.Cov ntaub ntawv rwb thaiv tsev feem ntau yog lub teeb, xoob, ntxeem tau, thiab qis thermal conductivity.Nws feem ntau yog siv los tiv thaiv kom tsis txhob muaj cua sov hauv cov khoom siv thermal thiab cov kav dej, los yog siv rau hauv khov (tseem hu ua txias txias) thiab tsis tshua muaj kub (tseem hu ua cryogenic), yog li cov ntaub ntawv rwb thaiv tsev kub hauv kuv lub teb chaws kuj hu ua cua sov preservation los yog txias preservation cov ntaub ntawv.Nyob rau tib lub sijhawm, vim qhov ntxeem tau lossis fibrous qauv ntawm cov khoom siv thermal rwb thaiv tsev nrog lub suab zoo nqus, nws kuj tau siv dav hauv kev tsim kho kev lag luam.
Cov khoom siv rwb thaiv tsev thermal muaj cov ntsuas kev ua haujlwm hauv qab no.
(1) Thermal conductivity.Raws li cov khoom siv thermal rwb thaiv tsev, thermal conductivity yuav tsum tsawg li tsawg tau.Feem ntau, cov thermal conductivity yuav tsum tsawg dua 0.14W / (mK).Raws li cov khoom siv thermal rwb thaiv tsev rau kev khaws cia txias, qhov xav tau rau thermal conductivity yog siab dua.
(2) Kev ntom ntom ntom nti, qhov tsis tshua muaj hnyav ntawm cov ntaub ntawv rwb thaiv tsev feem ntau, tab sis tib lub sijhawm me me, tab sis tib lub sijhawm ntawm lub tshuab tseem me me, tab sis ib qho kev xaiv tsim nyog yuav tsum tau ua .
(3) Mechanical zog.Txhawm rau tiv thaiv cov khoom siv rwb thaiv tsev thermal los ntawm deformed los yog puas nyob rau hauv nws tus kheej qhov hnyav thiab quab yuam, nws lub zog compressive yuav tsum tsis pub tsawg tshaj 3kg / cm.
(4) Tus nqi nqus dej.Tom qab cov khoom siv thermal rwb thaiv tsev absorbs dej, nws yuav tsis tsuas yog txo cov thermal rwb thaiv tsev kev ua tau zoo, l Nws yog heev tsim kev puas tsuaj rau hlau skimming.Yog li ntawd, lub vine yuav tsum xaiv cov khoom siv hluav taws xob uas muaj cua sov uas muaj qhov nqus dej tsawg.
(5) Thaum tshav kub kub tsis kam thiab siv qhov kub thiab txias, cov ntaub ntawv rwb thaiv tsev kub nrog cov khoom siv hluav taws xob sib txawv yuav tsum raug xaiv raws li qhov kub ntawm qhov chaw siv."Siv qhov kub thiab txias" yog lub hauv paus rau kev tiv thaiv tshav kub ntawm cov khoom siv thermal rwb thaiv tsev.
Cov ntaub ntawv saum toj no yog cov ntaub ntawv hais txog dab tsi yog cov rwb thaiv tsev kub thiab cov khoom siv refractory qhia los ntawm lub tuam txhab kev tiv thaiv hluav taws kub.Tsab ntawv los ntawm goldenpower Group
