Ntawm cov yam tseem ceeb uas cuam tshuam rau qhov zoo ntawm cov khoom siv hluav taws xob defrost cua sov, qhov zoo ntawm cov khoom siv yog ib qho laj thawj tseem ceeb. Kev xaiv cov khoom siv raw rau cov raj cua sov defrost yog qhov tseem ceeb ntawm kev ua kom zoo ntawm cov cua sov defrost.
1, txoj cai xaiv ntawm cov yeeb nkab: kub tsis kam, corrosion tsis kam.
Rau cov kav dej kub qis, BUNDY, cov kav dej txhuas, cov kav dej tooj liab feem ntau yog siv, thiab cov kav dej kub siab feem ntau yog cov kav hlau tsis xeb thiab cov kav dej Ingle. Ingle 800 lub raj cua sov tuaj yeem siv rau hauv qhov xwm txheej ntawm cov dej tsis zoo, Ingle 840 lub raj cua sov hluav taws xob tuaj yeem siv rau hauv qhov kub siab ua haujlwm muaj kev tiv thaiv oxidation zoo, muaj kev tiv thaiv corrosion zoo.
2, kev xaiv ntawm cov hlau tsis kam
Cov ntaub ntawv hlau tiv taus uas feem ntau siv rau hauv cov khoom siv hluav taws xob defrost cua sov yog Fe-Cr-Al thiab Cr20Ni80 hlau tiv taus. Qhov sib txawv tseem ceeb ntawm ob txoj hlau tiv taus yog tias qhov chaw yaj ntawm 0Cr25Al5 siab dua li ntawm Cr20Ni80, tab sis ntawm qhov kub siab dua, 0Cr25Al5 yooj yim dua rau oxidize, thiab Cr20Ni80 kuj tseem tuaj yeem tswj tau qhov ua tau zoo ruaj khov ntawm qhov kub siab. Yog li ntawd, cov hlau tiv taus siv ntawm qhov kub siab feem ntau yog Cr20Ni80.
3, kev xaiv ntawm MgO hmoov
Cov hmoov MgO nyob nruab nrab ntawm cov hlau tiv thaiv thiab phab ntsa ntawm lub raj thiab siv rau kev rwb thaiv tsev ntawm cov hlau tiv thaiv thiab phab ntsa ntawm lub raj. Tib lub sijhawm, cov hmoov MgO muaj cov thermal conductivity zoo. Txawm li cas los xij, cov hmoov MgO muaj cov khoom hygroscopic muaj zog, yog li nws yuav tsum tau kho nrog cov dej noo tiv taus (hloov kho MgO hmoov lossis kaw nrog cov yeeb nkab hluav taws xob cua sov) thaum siv.
MgO hmoov tuaj yeem muab faib ua hmoov kub qis thiab hmoov kub siab raws li qhov kub thiab txias siv. Hmoov kub qis tsuas yog siv tau hauv qab 400 ° C, feem ntau hloov kho MgO hmoov.
Cov hmoov MgO siv rau hauv cov yeeb nkab hluav taws xob cua sov yog tsim los ntawm cov hmoov MgO sib txawv tuab raws li qee qhov sib piv (mesh piv).
4, kev xaiv cov ntaub ntawv sealing
Lub luag haujlwm ntawm cov khoom siv sealing yog los tiv thaiv cov dej noo hauv huab cua kom tsis txhob nkag mus rau hauv MgO hmoov los ntawm lub qhov ncauj yeeb nkab, yog li ntawd MgO hmoov ntub, kev ua haujlwm rwb thaiv tsev txo qis, thiab cov yeeb nkab hluav taws xob cua sov xau thiab ua tsis tiav. Cov hmoov magnesia hloov kho tsis tuaj yeem kaw.
Cov ntaub ntawv tseem ceeb siv rau kev kaw lub raj cua sov fais fab (tsis muaj dej noo) yog iav, epoxy resin, roj silicone thiab lwm yam. Hauv cov yeeb nkab cua sov fais fab uas kaw nrog roj silicone, tom qab cua sov, cov roj silicone ntawm lub qhov ncauj ntawm cov yeeb nkab yuav raug cua sov ua kom yaj, thiab lub rwb thaiv tsev ntawm cov yeeb nkab cua sov fais fab yuav txo qis. Qhov kub tsis kam ntawm cov khoom siv epoxy resin tsis siab, thiab nws tsis tuaj yeem siv rau hauv cov yeeb nkab hluav taws xob kub siab xws li barbecue thiab microwave qhov cub nrog qhov kub siab ntawm lub qhov ncauj yeeb nkab. Iav muaj qhov kub tsis kam siab dua, tab sis tus nqi siab dua, thiab nws siv ntau dua rau kev kaw cov yeeb nkab kub siab.
Tsis tas li ntawd xwb, yuav muaj cov raj silicone, cov tes tsho silicone, cov hlaws dai porcelain, cov yas insulators thiab lwm yam khoom hauv lub qhov ncauj yeeb nkab, feem ntau yog kom nce qhov sib txawv hluav taws xob thiab qhov deb ntawm tus pas hlau thiab phab ntsa hlau ntawm lub qhov ncauj yeeb nkab. Cov roj hmab silicone tuaj yeem ua lub luag haujlwm ntawm kev sau thiab kev sib txuas.
