Qhov teeb meem no peb yuav txuas ntxiv ua kom paub cov kev faib tawm ntawm kev teeb liab rwb thaiv tsev hluav taws xob hluav taws xob ci ntsa iab rau iav.
3.Cov qabHnav Rag thaiv rwb thaiv tsev hluav taws cibCov. Nws yog rwb thaiv tsev refractory khoom ua los ntawm refractory clay nrog al2o3 cov ntsiab lus ntawm 30% ~ 48%. Nws cov txheej txheem ntau lawm tau txais tawm txoj kev ntxiv thiab ua npuas ncauj. Av nplaum lub teeb rwb thaiv tsev hluav taws xob cov ntaub ntawv hluav taws xob muaj ntau cov ntaub ntawv rwb thaiv tsev hauv ntau cov ntaub ntawv molten. Nws ua haujlwm kub yog 1200 ~ 1400 ℃.
4. Aluminium oxide rwb thaiv tsev cib. Cov khoom muaj hluav taws kub siab thiab zoo thermal poob siab kuj, thiab feem ntau siv los ua cov txheej kub siab rau hauv kilns. Nws ua haujlwm kub yog 1350-1500 ℃, thiab kev ua haujlwm ntawm cov khoom kub muaj peev xwm ncav cuag 1650-1800 ℃. Nws yog refractory rwb thaiv cov khoom lag luam ua los ntawm cov ntaub ntawv raw ntawm fused corundum, sintered alumina, thiab muaj alumina.
5. Hnav Mullite Cib. Thermal rwb thaiv tsev thiab cov khoom lag luam refractory ua los ntawm mullite raws li cov khoom siv tseem ceeb. Mullite rwb thaiv tsev cib muaj qhov kub siab, muaj zog, thiab lawv muaj peev xwm ncaj qha rau hauv ntau hauv ntau cov khoom siv muaj ntau yam.
6. Aluminium Oxide Hollow Ball Cib. Aluminium Oxide Hollow pob Cib yog siv rau kev siv ntev hauv qab 1800 ℃. Nws muaj cov tshuaj ruaj khov zoo thiab corrosion tsis kam ntawm cov kub. Piv nrog lwm lub teeb liab rwb thaiv tsev cib pob tawb ntau dua, muaj zog dua, thiab qis dua thermal conductivity. Nws qhov ntom ntom kuj yog 50% ~ qis dua li cov khoom siv tsis zoo ntawm tib qho kev sib xyaw ua ke, thiab tuaj yeem tiv thaiv qhov cuam tshuam ntawm cov nplaim taws kub.
