Ntawm cov xwm txheej cuam tshuam rau qhov zoo ntawm hluav taws xob defrost cua sov, qhov zoo ntawm cov khoom yog qhov tseem ceeb.Tsim nyog xaiv cov ntaub ntawv raw rau defrost cua sov raj yog lub hauv paus ntawm kev ua kom ntseeg tau qhov zoo ntawm defrost rhaub.
1, xaiv txoj cai ntawm cov yeeb nkab: kub tsis kam, corrosion kuj.
Rau cov kav dej kub tsawg, BUNDY, cov kav dej txhuas, cov kav dej tooj liab feem ntau yog siv, thiab cov kav dej kub kub feem ntau yog cov kav hlau stainless thiab Ingle kav.Ingle 800 heatig tube tuaj yeem siv rau hauv cov dej tsis zoo, Ingle 840 hluav taws xob cua sov raj tuaj yeem siv rau hauv qhov kub thiab txias ua haujlwm muaj qhov zoo oxidation tsis kam, muaj kev tiv thaiv corrosion zoo.
2, kev xaiv cov hlau tsis kam
Cov ntaub ntawv tiv thaiv hlau feem ntau siv hauv hluav taws xob tiv thaiv hluav taws xob yog Fe-Cr-Al thiab Cr20Ni80 tsis kam xaim.Qhov sib txawv tseem ceeb ntawm ob txoj hlua hluav taws xob yog tias lub melting point ntawm 0Cr25Al5 yog siab dua li ntawm Cr20Ni80, tab sis nyob rau ntawm qhov kub thiab txias, 0Cr25Al5 yog yooj yim rau oxidize, thiab Cr20Ni80 kuj tseem muaj kev ruaj ntseg ntawm qhov kub thiab txias.Yog li, cov hlau tsis kam siv ntawm qhov kub thiab txias feem ntau yog Cr20Ni80.
3, kev xaiv ntawm MgO hmoov
MgO hmoov yog nyob nruab nrab ntawm cov hlau tsis kam thiab cov phab ntsa ntawm lub raj thiab siv rau kev rwb thaiv tsev ntawm cov hlau tsis kam thiab cov phab ntsa ntawm lub raj.Nyob rau tib lub sijhawm, MgO hmoov muaj cov thermal conductivity zoo.Txawm li cas los xij, MgO hmoov muaj cov khoom muaj zog hygroscopic, yog li nws yuav tsum tau kho nrog dej tsis kam (hloov MgO hmoov los yog kaw nrog cov yeeb nkab hluav taws xob) thaum siv.
MgO hmoov tuaj yeem muab faib ua cov hmoov tsis kub thiab cov hmoov kub kub raws li qhov kub thiab txias siv.Cov hmoov tsis kub tsuas yog siv tau qis dua 400 ° C, feem ntau hloov MgO hmoov.
MgO hmoov siv nyob rau hauv hluav taws xob cua sov yeeb nkab yog tsim los ntawm txawv thickness MgO hmoov hais raws li ib tug tej yam kev faib ua feem (mesh ratio).
4, kev xaiv cov khoom sib khi
Lub luag haujlwm ntawm cov khoom sib khi yog txhawm rau tiv thaiv huab cua noo los ntawm kev nkag mus rau MgO hmoov los ntawm cov yeeb nkab qhov ncauj, kom cov hmoov MgO ntub dej, kev ua haujlwm rwb thaiv tsev raug txo, thiab hluav taws xob cov yeeb nkab xau thiab tsis ua haujlwm.Hloov cov hmoov magnesia tsis tuaj yeem raug kaw.
Cov ntaub ntawv tseem ceeb siv rau kev sib khi hluav taws xob cua sov tube (cov dej tsis muaj pov thawj) yog iav, epoxy resin, silicone roj thiab lwm yam.Nyob rau hauv cov hluav taws xob cua sov yeeb nkab kaw nrog silicone roj, tom qab cua sov, cov roj silicone ntawm lub qhov ncauj ntawm cov yeeb nkab yuav volatilized los ntawm tshav kub, thiab cov rwb thaiv tsev ntawm cov hluav taws xob cua sov yeeb nkab yuav txo.Qhov kub tsis kam ntawm cov khoom siv epoxy resin tsis siab, thiab nws tsis tuaj yeem siv rau hauv cov kav dej kub kub xws li barbecue thiab microwave qhov cub nrog kub kub ntawm lub qhov ncauj qhov ncauj.Cov iav muaj qhov kub thiab txias tsis kam, tab sis tus nqi siab dua, thiab nws siv ntau dua rau kev sib khi cov kav dej kub.
Tsis tas li ntawd, yuav muaj cov raj silicone, lub tes tsho silicone, cov hlaws dai, cov yas insulators thiab lwm yam hauv cov yeeb nkab qhov ncauj, feem ntau yuav ua rau kom cov hluav taws xob sib txawv thiab qhov kev ncua deb ntawm cov hlau lead pas nrig thiab cov phab ntsa hlau ntawm cov yeeb nkab qhov ncauj.Silicone roj hmab tuaj yeem ua lub luag haujlwm ntawm kev sau thiab kev sib txuas.
