Ua ib yam khoom siv ib txwm muaj, cov khoom siv av nplaum ua lub luag haujlwm tseem ceeb hauv ntau qhov chaw. Txawm li cas los xij, cov khoom siv av nplaum ib txwm muaj qhov tsis yooj yim tawg thiab tsis yooj yim tawg, uas txwv lawv txoj kev siv. Txhawm rau kom kov yeej qhov kev txwv no, cov khoom siv av nplaum uas tawv, ua ib yam khoom siv tshiab, tau nyiam kev saib xyuas dav dav.
1. Cov yam ntxwv ntawm cov khoom siv alumina uas tawv
Cov khoom siv alumina ceramic uas ruaj khovyog cov khoom siv ceramic uas muaj zog thiab tawv. Piv nrog cov khoom siv alumina ceramics ib txwm muaj, nws muaj cov yam ntxwv tseem ceeb hauv qab no:
1). Lub zog siab: Lub zog ntawm cov khoom siv alumina ceramics uas tawv dua yog siab dua li cov khoom siv ceramic ib txwm muaj. Qhov no yog vim nws cov qauv zoo thiab cov ntaub so ntswg sib npaug, uas ua rau nws tiv taus cov zog sab nraud ntau dua yam tsis yooj yim tawg.
2). Kev tawv zoo: Cov alumina ceramics uas tawv dua muaj kev tawv zoo thaum muaj zog siab. Qhov no txhais tau tias txawm tias nyob rau hauv lub zog sab nraud xws li kev cuam tshuam lossis kev cuam tshuam, nws tuaj yeem tswj tau kev ncaj ncees thiab kev ruaj khov thiab tsis yooj yim tawg.
3). Kev tiv taus zoo heev: Cov khoom siv alumina ceramics uas tawv thiab ruaj khov muaj kev tiv taus zoo heev thiab tsim nyog rau kev siv hauv ntau qhov chaw hnav hnyav. Qhov no ua rau nws muaj kev cia siab dav hauv kev tsim kho tshuab, kev lag luam tsheb, kev khawb av thiab lwm yam teb.
2. Txoj kev npaj ntawm cov khoom siv alumina uas tawv
Yuav kom npaj tau cov alumina ceramics uas tawv, Zhishun Ceramics Factory siv ntau txoj kev, feem ntau suav nrog kev ntxiv cov theem tawv thiab hloov cov qauv me me.
1). Ntxiv cov theem tawv: Los ntawm kev ntxiv cov theem tawv kom tsim nyog, xws li zirconium oxide, silicon carbide, thiab lwm yam, qhov tawv ntawm alumina ceramics tuaj yeem txhim kho tau zoo. Cov theem tawv no tuaj yeem tsim cov nyhuv txuas ntawm cov ciam teb ntawm cov noob thiab cov khoom me me, cuam tshuam kev nthuav dav ntawm qhov tawg, thiab yog li ua rau cov khoom siv tawv ntxiv.
2). Kev hloov cov qauv me me: Los ntawm kev tswj cov noob loj thiab kev faib tawm ntawm cov khoom siv ceramics, nws cov khoom siv kho tshuab tuaj yeem txhim kho tau zoo heev. Cov txheej txheem siv feem ntau suav nrog kev siv tshuab ua kom cov noob zoo, kev kho cua sov thiab cov txheej txheem nias. Cov txheej txheem no tuaj yeem tshem tawm cov qhov tsis zoo hauv cov khoom siv thiab txhim kho lub zog thiab kev ruaj khov ntawm cov ciam teb noob.
3. Cov teb thov ntawm cov khoom siv alumina uas tawv
Vim lawv qhov kev ua tau zoo heev, cov alumina ceramics muaj kev cia siab dav hauv ntau qhov chaw.
1). Kev ua haujlwm aerospace: Cov khoom siv alumina ceramics uas muaj zog heev muaj kev tiv thaiv kub thiab tiv thaiv corrosion, thiab tsim nyog rau cov ntawv thov hauv qhov chaw kub xws li cov khoom siv aerospace engine thiab cov combustion chamber liners.
2). Cov khoom siv kho mob: Cov khoom siv alumina uas tawv dua muaj biocompatibility thiab hnav tsis kam, thiab siv tau los ua cov khoom siv kho mob xws li cov pob qij txha dag thiab cov ntaub ntawv kho hniav, muab kev ruaj khov thiab kev nplij siab zoo dua.
3). Kev siv hluav taws xob: Cov khoom siv alumina ceramics uas muaj zog muaj cov khoom rwb thaiv tsev zoo heev thiab cov thermal conductivity, thiab siv tau los ua cov khoom siv hluav taws xob xws li cov insulators siab thiab cov ntaub ntawv ntim khoom hluav taws xob los txhim kho kev ntseeg siab thiab kev ua tau zoo ntawm cov khoom siv.
4). Kev lag luam tsheb: Lub zog siab thiab kev hnav tsis kam ntawm cov khoom siv alumina uas tawv ua rau nws yog qhov kev xaiv zoo tshaj plaws rau cov khoom siv tsheb xws li lub tshuab nres thiab cov khoom siv cav, txhim kho kev nyab xeeb thiab kev ua tau zoo ntawm cov tsheb.
Ua ib yam khoom siv tshiab, cov khoom siv alumina ceramics uas tawv tawv kov yeej qhov teeb meem brittleness ntawm cov khoom siv ceramic ib txwm muaj thiab muaj lub zog siab, tawv zoo thiab tiv taus kev hnav zoo heev. Nws muaj kev cia siab dav dav hauv kev siv dav hlau, khoom siv kho mob, khoom siv hluav taws xob thiab kev lag luam tsheb. Chemshun Ceramics tsim thiab xa tawm cov khoom siv alumina ceramics uas tawv tawv. Txais tos kom sab laj.
