Hauv qee lub qhov cub kub siab, thaum qhov kub hauv lub cub tawg tshaj 1200 ℃, cov khoom siv hlau ib txwm tab tom mus txog qhov chaw tseem ceeb, thaum pebsilicon carbide hluav taws xob rajtab tom xa lub zog nce siab nrog lub zog hluav taws xob ruaj khov - qhov no yog qhov me me ntawm kev rov ua dua ntawm cov thev naus laus zis kub siab niaj hnub. Raws li kev hloov pauv tshiab hauv thaj chaw ntawm cov ntaub ntawv tiv taus kub siab, cov raj hluav taws xob silicon carbide ua lub luag haujlwm tseem ceeb hauv kev lag luam kub siab ua "lub plawv kub siab".
Kev Hloov Pauv Khoom Siv: Thaum Lub Chaw Ua Haujlwm Thermal ntsib Silicon Carbide
Cov raj xa hluav taws xob ib txwm muaj feem ntau ntsib qhov tsis zoo xws li thermal deformation thiab oxidation corrosion hauv kev ua haujlwm siab dua 1200 ℃. Kev yug los ntawm silicon carbide (SiC) tau rov sau dua qhov teeb meem no: nws qhov Mohs hardness siab txog li 9.5, melting point tshaj 2700 ℃, thermal conductivity yog tsib zaug ntawm 316 stainless hlau, thiab nws muaj kev tiv thaiv thermal poob siab zoo heev - txawm tias tom qab ntsib qhov cuam tshuam tam sim ntawd ntawm 1350 ℃ kub thiab dej kub hauv chav, nws tseem tswj tau qhov kev ua haujlwm zoo.
Kev tshawb pom tshiab txog thev naus laus zis: Peb qhov zoo tseem ceeb los tsim kho dua tshiab cov qauv kev lag luam
1. Kev nce ntxiv ntawm kev ua haujlwm thermal zoo
Lub qauv siv lead ua los ntawm cov honeycomb zoo li silicon carbide ua rau muaj kev ua haujlwm zoo ntawm cov hluav taws xob thermal, thiab nrog kev tsim cov cua sov ntws, nws txo cov teeb meem thermal field uniformity thiab tswj lawv kom ruaj khov.
2. Kev hloov pauv ntawm kev siv hluav taws xob
Hauv cov ntawv thov rau lub cub tawg hauv kev lag luam, thaum qhov kub ntawm cov raj hluav taws xob silicon carbide raug txo los ntawm 200 ℃ piv rau cov raj hlau, lawv tseem khaws cov cua sov zoo ib yam, thiab kev txuag hluav taws xob txhua xyoo ntawm ib txoj kab ntau lawm yog qhov tseem ceeb heev.
3. Kev Hloov Pauv Lub Neej
Qhov kev ua haujlwm tiv thaiv carburizing tau zoo dua 8 zaug, thiab lub sijhawm ua haujlwm tas mus li hauv lub cub tawg carburizing tau tshaj 20000 teev, uas yog 5-10 npaug ntev dua li lub neej ua haujlwm ntawm cov ntaub ntawv ib txwm muaj.
Kev xaiv txoj kev txawj ntse: txoj cai kub rau kev yuav khoom lag luam
Vim muaj qhov sib txawv ntawm kev ua tau zoo ntawm cov khoom lag luam hauv kev ua lag luam, nws raug pom zoo kom tsom mus rau:
1. Kev huv ntawm silicon carbide
2. Coefficient ntawm thermal expansion
3. Lub zog khoov
4. Puas yog lub chaw tsim khoom muaj cov txheej txheem sintering tiav?
Peb xav kom cov neeg siv khoom ua "kev txheeb xyuas peb theem": kev kuaj xyuas kev poob siab thermal hauv chaw kuaj mob → kev ua haujlwm tas mus li ntawm cov kab tsav dav hlau → kev taug qab cov ntaub ntawv loj kom ntseeg tau tias cov khoom siv sib phim nrog cov kab ntau lawm.
Xaus lus
Nyob rau hauv kev tawm tswv yim niaj hnub no rau kev txuag hluav taws xob ntsuab, cov raj xa hluav taws xob silicon carbide tau hloov zuj zus los ntawm lwm txoj kev xaiv mus rau qhov kev xaiv tsis zam rau cov khoom siv thermal industrial. Ua ib lub koom haum thev naus laus zis uas tau koom nrog tob hauv kev lag luam ntawm cov khoom siv ceramic tshwj xeeb rau ntau tshaj kaum xyoo, peb txuas ntxiv mus hla cov kev txwv ntawm cov txheej txheem sintering thiab siv zog los ua kom tau raws li ntau yam kev xav tau ntawm peb cov neeg siv khoom nrog qhov zoo.
Txais tos tuaj xyuasShandong Zhongpengrau cov kev daws teeb meem thermal uas tau kho raws li koj xav tau, lossis hu rau (+86)15254687377 kom teem sijhawm kuaj xyuas kev siv hluav taws xob zoo rau cov kab ntau lawm - cia peb pib ua ke rau txoj kev hloov pauv tom ntej ntawm kev kho cua sov hauv kev lag luam.
