Kev xaiv ntawm magnesium oxide hmoov sealing khoom rau ib lub taub hau hluav taws xob cua sov raj
Ntawm cov yam ntxwv uas cuam tshuam rau qhov zoo ntawm ib lub taub hau hluav taws xob cua sov raj, qhov zoo ntawm cov khoom yog qhov tseem ceeb. Tsim nyog xaiv cov ntaub ntawv raw rau ib lub taub hau hluav taws xob cua sov kav yog ib qho yuav tsum tau ua ua ntej kom ntseeg tau qhov zoo ntawm ib lub taub hau hluav taws xob cua sov kav.
1. Txoj kev xaiv ntawm cov kav dej: qhov kub thiab txias tsis kam thiab corrosion kuj.
Rau cov kav dej kub qis, BUNDY, cov kav dej txhuas, thiab cov kav dej tooj liab feem ntau yog siv, thaum cov kav dej kub feem ntau siv cov kav hlau tsis muaj steel thiab cov kav dej Askiv. Ingley 800 ib lub taub hau hluav taws xob cua sov raj tuaj yeem siv rau hauv cov dej tsis zoo, thaum Ingley 840 ib lub taub hau hluav taws xob cua sov raj tuaj yeem muaj qhov zoo oxidation tsis kam thiab corrosion kuj nyob rau hauv kub kub ua haujlwm.
2. Kev xaiv cov hlau tsis kam
Cov khoom siv hluav taws xob siv hluav taws xob feem ntau siv hauv ib lub taub hau hluav taws xob cua sov raj muaj xws li Fe Cr Al thiab Cr20Ni80 cov xov hlau tsis kam. Cov hlau chromium hlau xaiv los ntawm KAWAI yog ntawm 0Cr25Al5 hom, uas muaj cov ntsiab lus melting ntau dua thiab kev pab cuam lub neej zoo dua piv rau cov hlau chromium zoo tib yam. Qhov sib txawv tseem ceeb ntawm ob hom kev tiv thaiv xov hlau yog tias lub melting point ntawm 0Cr25Al5 yog siab dua li ntawm Cr20Ni80, tab sis nyob rau hauv qhov kub thiab txias, 0Cr25Al5 yog oxidation ntau dua, thaum Cr20Ni80 muaj peev xwm tuav ruaj khov kev ua tau zoo ntawm qhov kub thiab txias. Yog li ntawd, cov xov hlau tsis kam siv ntawm qhov kub thiab txias feem ntau siv Cr20Ni80.
3. Kev xaiv ntawm magnesium oxide hmoov
Magnesium oxide hmoov yog nyob nruab nrab ntawm cov hlau tsis kam thiab cov yeeb nkab phab ntsa, siv rau rwb thaiv tsev ntawm cov hlau tsis kam thiab cov yeeb nkab phab ntsa. Lub caij no, magnesium oxide hmoov kuj muaj thermal conductivity zoo. Txawm li cas los xij, magnesium oxide hmoov muaj qhov muaj zog hygroscopicity, yog li nws yuav tsum tau kho cov dej noo-pov thawj (hloov nrog magnesium oxide hmoov los yog kaw nrog ib lub taub hau hluav taws xob cua sov raj) thaum siv.
Magnesium oxide hmoov tuaj yeem muab faib ua ob hom raws li qhov kub thiab txias siv: hmoov tsis kub thiab kub-kub hmoov. Cov hmoov tsis kub tsuas yog siv tau qis dua 400 degree, feem ntau hloov magnesium oxide hmoov.
Magnesium oxide hmoov yog granular, thiab magnesium oxide hmoov siv rau ib lub taub hau hluav taws xob cua sov raj yog tsim los ntawm magnesium oxide hais ntawm txawv thicknesses nyob rau hauv ib tug tej yam kev faib ua feem (mesh ratio).
4. Kev xaiv cov khoom sib khi
Kev ua haujlwm ntawm cov ntaub ntawv sib khi yog tiv thaiv kom tsis txhob ya raws hauv huab cua los ntawm kev nkag mus rau magnesium oxide hmoov los ntawm cov yeeb nkab lub qhov ncauj, ua rau cov magnesium oxide hmoov ua ntub dej, txo cov rwb thaiv tsev kev ua tau zoo, thiab ua rau ib qho kawg hluav taws xob cua sov kav xau thiab ua tsis tiav. Hloov kho magnesium oxide hmoov tuaj yeem raug tso tseg.
Cov ntaub ntawv siv rau kev sib khi (nqus-pov thawj) ib lub taub hau hluav taws xob cua sov kav feem ntau muaj xws li iav, epoxy resin, silicone roj, thiab lwm yam. Lub taub hau hluav taws xob cua sov lub raj kaw nrog cov roj silicone yuav muaj evaporation ntawm silicone roj ntawm lub nozzle tom qab cua sov, ua rau. nyob rau hauv ib tug txo nyob rau hauv rwb thaiv tsev ntawm ib lub taub hau hluav taws xob cua sov raj. Epoxy resin cov ntaub ntawv muaj qhov kub thiab txias tsis zoo thiab tsis tuaj yeem siv rau hauv qhov kub thiab txias ib lub taub hau hluav taws xob cua sov kav xws li barbecues thiab microwave ncu nrog kub nozzle. Cov iav muaj qhov kub thiab txias tsis kam, tab sis nws cov nqi kuj yog siab heev, thiab nws yog siv rau sealing high-temperature kav.
Tsis tas li ntawd, yuav muaj cov raj silicone, lub tes tsho silicone, cov hlaws dai, cov yas insulators thiab lwm yam khoom ntawm 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 tawm pas nrig thiab cov phab ntsa hlau ntawm cov yeeb nkab qhov ncauj. Silicone roj hmab tuaj yeem ua lub luag haujlwm hauv kev sau thiab kev sib txuas.
