Rau cov neeg yuav khoom thoob ntiaj teb uas tab tom nrhiav kev daws teeb meem lim dej txhim khu kev qha, kev nkag siab txog kev faib tawm thiab kev hloov kho yog qhov tseem ceeb rau kev xaiv cov khoom zoo.

Kev Faib Tawm Tseem Ceeb ntawm Cov Lim Ua Npuas Ncauj Ua Los Ntawm Cov Khoom Siv ...
Cov lim dej ua npuas ncauj feem ntau yog muab faib ua pawg los ntawm cov khoom siv, txhua tus tsim rau qhov kub thiab txias tshwj xeeb thiab hom hlau.

1. Alumina Ceramic Ua Npuas Ncauj Lim
Xim dawb, nrog rau qhov kub ua haujlwm txog li 1250 ° C. Nws yog lub lim dej siv dav tshaj plaws rau cov hlau txhuas, cov hlau txhuas sib xyaw, tooj liab, thiab lwm yam hlau uas tsis yog hlau. Nws muaj kev tiv taus cua sov zoo heev, ntws ruaj khov, thiab ua haujlwm tau zoo, zoo tagnrho rau cov khoom siv hauv tsheb, lub log tsheb txhuas, thiab kev casting uas tsis yog hlau.

2. Silicon Carbide (SiC) Ceramic Ua Npuas Ncauj Lim
Xim grey los yog dub, tiv taus cua sov txog li 1500°C. Nws muaj lub zog siab, ua kom muaj cua sov zoo, thiab tiv taus xeb zoo. Feem ntau siv rau cov hlau grey, hlau ductile, thiab qee cov hlau sib xyaw. Nws txo cov slag thiab porosity, txhim kho cov txiaj ntsig casting thiab kev ua haujlwm machining.

3. Zirconia Ceramic Ua Npuas Ncauj Lim
Xim daj, nrog rau qhov kub thiab txias heev txog li 1760°C. Nws yog tsim tshwj xeeb rau cov hlau molten, stainless hlau, thiab cov alloys kub siab xws li nickel-based thiab cobalt-based superalloys. Nws muab kev ruaj khov tshwj xeeb hauv cov xwm txheej nyuaj, ua kom muaj kev ntshiab siab rau kev nqis peev casting, aerospace, thiab cov khoom siv kho mob.

Cov lim dej kuj tseem tuaj yeem muab faib ua pawg los ntawm qhov ceev ntawm qhov (10–100 PPI), cov duab (square, round, rectangular), thiab thickness kom phim cov nqi ntws sib txawv thiab cov kev xav tau ntawm qhov tseeb.

Kev Pabcuam Kho Kom Haum Rau Cov Kev Siv Hauv Kev Lag Luam
Cov chaw tsim khoom tshaj lij txhawb nqa kev hloov kho kom haum rau ntau yam kab ntau lawm thiab cov xwm txheej ua haujlwm tshwj xeeb.

Kev Kho Khoom Siv
Xaiv cov alumina, silicon carbide, zirconia, thiab lwm yam qauv sib xyaw raws li hom hlau, qhov kub thiab txias, thiab qhov chaw xeb.

Kev Kho Kom Loj & Duab
Kev cai ntev, dav, txoj kab uas hla, thiab tuab kom haum rau cov thawv lim dej, cov tshuab ntxhua khaub ncaws, thiab cov khob nchuav. Cov duab feem ntau suav nrog plaub fab, puag ncig, oval, thiab cov profile tshwj xeeb.

Kev Kho Kom Zoo Nkauj ntawm Cov Qauv Pore
Xaiv 10–100 PPI kom sib npaug qhov kev lim dej kom raug thiab qhov ceev ntawm kev ntws. Cov qhov me me (50–100 PPI) ntes cov khoom me me rau cov khoom siv casting siab; cov qhov loj me (10–30 PPI) ua kom muaj kev ntws du rau cov khoom tuab.

Kev Txhim Kho Kev Ua Haujlwm
Ntxiv cov tshuaj tiv thaiv oxidation, tiv thaiv xeb, lossis cov txheej txheem txhawb nqa kom ntev lub neej kev pabcuam thiab txhim kho kev ruaj khov nyob rau hauv cov xwm txheej hnyav.
Cov lim dej ua npuas ncauj ua los ntawm cov khoom siv ceramic tshwj xeeb pab cov lag luam txo cov nqi tsis lees txais, txo cov nqi tsim khoom, thiab ua tau raws li cov qauv zoo thoob ntiaj teb rau kev lag luam tsheb, aerospace, machinery, thiab electronics.

Vim Li Cas Xaiv Cov Neeg Muag Khoom Siv Ua Npuas Ncauj Ceramic
Zoo ruaj khov, porosity sib xws, lub zog siab, thiab tiv taus thermal shock tiv thaiv kev tawg thaum siv. Kev hloov kho tag nrho los ntawm cov khoom siv mus rau qhov loj me ua kom muaj kev sib raug zoo nrog koj cov txheej txheem. Kev tshuaj xyuas zoo nruj thiab kev xa khoom sai thoob ntiaj teb txhawb nqa kev tsim khoom ruaj khov.

Txawm koj xav tau cov lim dej txheem lossis cov lim dej uas hloov kho tas li, cov kev daws teeb meem tshaj lij yuav txhim kho qhov zoo ntawm kev ua casting thiab txhawb kev sib tw. Tiv tauj peb hnub no rau kev xaiv cov khoom siv, kev tsim qauv kho kom haum, thiab cov kev daws teeb meem lim dej uas pheej yig.
