Shandong Zhongpeng Special Ceramics Co., Ltd. siv cov khoom no los tsim cov khoom siv silicon carbide zoo uas ua tau raws li qhov xav tau ntawm ntau yam lag luam.

Ntawm qhov tod tes, cov khoom siv silicon nitride ceramics muaj cov khoom siv kho tshuab zoo heev, suav nrog lub zog siab thiab kev tawv. Si3N4 ceramics, ua los ntawm silicon thiab nitrogen, tshwj xeeb tshaj yog tiv taus kev poob siab thermal thiab muaj cov coefficient qis dua ntawm kev nthuav dav thermal piv rau silicon carbide. Qhov no ua rau silicon nitride ceramics yog qhov kev xaiv zoo heev rau cov ntawv thov uas xav tau cov ntaub ntawv los tiv taus kev hloov pauv kub sai, xws li cov roj turbines thiab cov cuab yeej txiav. Silicon nitride lub microstructure tshwj xeeb kuj muab nws cov tawv tawg zoo heev, ua rau nws yog cov khoom siv xaiv rau kev lag luam uas xav tau cov khoom siv ruaj khov.

Thaum piv ob yam khoom siv, ib qho ntawm qhov sib txawv tseem ceeb tshaj plaws yog lawv cov khoom siv thermal. Silicon carbide ceramics tuaj yeem tiv taus qhov kub siab dua li silicon nitride ceramics, ua rau lawv tsim nyog rau kev siv hauv cov ntawv thov kub heev. Txawm li cas los xij, silicon nitride lub peev xwm los tiv taus thermal shock muab nws qhov zoo dua hauv cov chaw uas muaj kev hloov pauv kub hnyav. Qhov sib txawv no yog qhov tseem ceeb rau cov engineers thiab cov neeg tsim qauv thaum xaiv cov khoom siv rau ib daim ntawv thov tshwj xeeb, vim tias kev xaiv cov khoom siv tuaj yeem cuam tshuam rau kev ua haujlwm thiab lub neej kev pabcuam.

Lwm qhov sib txawv loj ntawm silicon carbide thiab silicon nitride ceramics yog lawv cov tshuaj lom neeg ruaj khov. Silicon carbide tiv taus oxidation heev thiab tuaj yeem tswj nws cov khoom txawm tias nyob rau hauv cov chaw muaj tshuaj lom neeg corrosive. Qhov no ua rau nws zoo tagnrho rau kev ua tshuaj lom neeg thiab kev tsim khoom semiconductor. Hauv kev sib piv, silicon nitride ceramics, thaum ruaj khov tshuaj lom neeg, tej zaum yuav tsis ua haujlwm zoo hauv qee qhov chaw muaj tshuaj lom neeg corrosive. Kev nkag siab txog cov khoom siv tshuaj lom neeg no yog qhov tseem ceeb rau kev lag luam ua haujlwm hauv cov xwm txheej nyuaj vim nws cuam tshuam rau kev xaiv cov khoom siv thiab kev tsim khoom.

Cov txheej txheem tsim khoom rau silicon carbide thiab silicon nitride ceramics kuj txawv ntau heev. Silicon carbide ceramics feem ntau yog tsim los ntawm sintering, ib qho txheej txheem uas cuam tshuam nrog cua sov cov khoom siv rau qhov kub qis dua nws qhov melting point kom ua tiav densification. Txoj kev no tuaj yeem tsim cov duab nyuaj thiab cov khoom ntom ntom. Qhov sib piv, silicon nitride ceramics feem ntau yog tsim los ntawm kev siv cov txheej txheem ua hmoov thiab sintering, suav nrog kev nias kub lossis kev sib txuas lus. Cov kev sib txawv no hauv cov txheej txheem tsim khoom tuaj yeem cuam tshuam rau cov khoom kawg ntawm ceramic, suav nrog nws cov microstructure thiab cov khoom siv kho tshuab.

Hais txog tus nqi, cov khoom siv silicon carbide ceramics feem ntau kim dua li cov khoom siv silicon nitride ceramics vim yog cov khoom siv raw thiab cov thev naus laus zis ua tiav. Txawm li cas los xij, kev ua tau zoo mus sij hawm ntev thiab kev ruaj khov ntawm silicon carbide tuaj yeem ua pov thawj rau kev nqis peev pib siab dua, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas qhov tsis ua haujlwm tuaj yeem ua rau muaj kev pheej hmoo loj lossis kev nyab xeeb. Shandong Zhongpeng Special Ceramics Co., Ltd. tsom mus rau kev muab cov kev daws teeb meem pheej yig yam tsis muaj kev cuam tshuam zoo, kom ntseeg tau tias cov neeg siv khoom tau txais txiaj ntsig zoo tshaj plaws rau lawv cov peev txheej hauv silicon carbide ceramics.

Hauv kev xaus, qhov sib txawv ntawm silicon carbide ceramics thiab silicon nitride ceramics yog qhov tseem ceeb thiab tuaj yeem cuam tshuam loj heev rau lawv daim ntawv thov thoob plaws ntau yam kev lag luam. Silicon carbide ua tau zoo heev hauv qhov kub thiab txias thiab cov tshuaj lom neeg corrosive, thaum silicon nitride qhia txog kev tawv zoo heev thiab tiv taus thermal shock. Kev nkag siab txog qhov sib txawv no yog qhov tseem ceeb rau cov engineers thiab cov chaw tsim khoom thaum xaiv cov ntaub ntawv rau cov ntawv thov tshwj xeeb. Ua tus thawj coj tsim khoom ntawm silicon carbide ceramics, Shandong Zhongpeng Special Ceramics Co., Ltd. tau cog lus tias yuav txhim kho kev lag luam ntawm cov khoom siv ceramics siab heev, muab cov khoom zoo uas ua tau raws li qhov xav tau ntawm kev lag luam niaj hnub no. Los ntawm kev siv cov khoom tshwj xeeb ntawm silicon carbide thiab silicon nitride, cov tuam txhab tuaj yeem ua kom zoo dua lawv cov qauv tsim thiab txhim kho kev ua tau zoo ntawm lawv cov khoom, thaum kawg ua rau muaj kev ua haujlwm zoo thiab kev ntseeg siab ntawm lawv cov haujlwm.
