Los ntawm cov txheej txheem ntawm cov khoom siv ceramic, muaj peb yam tseem ceeb cuam tshuam rau nws qhov zoo: cov khoom siv raw silicon carbide hmoov, thiab qhov ntim qhov hnyav thiab compressive zog Performance index ntawm raw silicon carbide hmoov yuav txawv nrog ntau yam sib txawv.
Nyob rau hauv tib lub siab sib sau, sib txawv sib txawv siab yuav cuam tshuam qhov zoo ntawm sintered silicon carbide beam roller. Nws txoj kev tsim khoom muaj ntau yam, ua rau cov khoom tsis sib xws.
Dab tsi ntawm cov menyuam yaus ceramic yog tsim nyog nyob ntawm seb muaj pes tsawg leeg ntawm ntsuab silicon carbide hmoov, yog li koj tuaj yeem xaiv koj tus kheej cov khoom.
Qhov zoo tshaj plaws thermal yog vim qhov thermal shock tshwm sim los ntawm kev hloov pauv ntawm qhov kub thiab txias ntawm cov menyuam ceramic, uas ua rau muaj kev ntxhov siab thermal. Rau cov ntaub ntawv nrog sib txawv thermal expansion coefficients, thermal shock yuav tshwm sim thaum kub hloov dheev, thiab rau nws, qhov thermal shock yuav tsim microcracks los yog txawm tuag kab nrib pleb. Piv txwv li, thaum hloov tus pas nrig, lub thermal shock ntawm cov menyuam thaum nws thauj mus rau hauv lub kiln los ntawm sab nraum lub kiln los yog tshem tawm ntawm lub kiln yuav ua rau cov khoom puas ntsoog, los yog hloov cov muaj pes tsawg leeg ntawm cov iav tivthaiv nyob rau hauv ntsuab. lub cev ntawm qhov kub ntawm qhov hluav taws kub ntau dua kom nce lossis txo nws, yog li hloov cov thermal expansion coefficient ntawm lub cev ntsuab. Thaum qhov kub hloov pauv tam sim ntawd, nws yuav ua rau deformation lossis puas thiab puas.
Nyob rau hauv qhov kev txiav txim tas mus li ntawm lub load, lub load yuav tsim ib qho kev sib hloov ntawm kev ntxhov siab ntawm cov menyuam ceramic, tshwj xeeb tshaj yog nyob rau hauv qhov kev ua haujlwm tas li ntawm qhov kub thiab txias. Qhov kev hloov pauv no yuav ua rau muaj kev puas tsuaj rau cov menyuam, ua rau qaug zog, ua rau cov khoom tsis zoo, tawg me me, thiab tawg qeeb. Nws yog qhov pom tseeb tias cov khoom sib txawv yuav ua rau muaj kev hloov pauv ntawm cov theem sib txawv, thiab thaum kawg ua rau puas tsuaj.
