Tabular Alumina Tsawg Porosity
Tabular corundum yog ua los ntawm cov hmoov alumina txawv teb chaws, tom qab batting, sib tsoo thiab sib sau, ces firing nyob rau hauv lub ultra-siab kub ncej kiln tom qab 1900 degree siab kub. Nrog cov ntim siab, tsis tshua muaj porosity thiab dej nqus, zoo thermal shock stability, tsis tshua muaj shrinkage, nws yog cov khoom tshiab rau refractory, ceramic thiab insulating.

Kev piav qhia
Tabular alumina yog ib qho kev xaiv zoo rau kev kub siab castable refractories vim nws cov yam ntxwv zoo. Nws muaj qhov tshwj xeeb refractoriness thiab thermal stability, ua rau nws tiv taus qhov kub thiab txias yam tsis muaj kev cuam tshuam nws cov qauv kev ntseeg siab. Nrog nws cov purity siab thiab tsis tshua muaj porosity, tabular alumina muaj kev txhim khu kev qha thiab kev pheej hmoo tsawg ntawm kev sib kis lossis kev cuam tshuam nrog lwm cov ntaub ntawv. Nws siv nyob rau hauv high-temperature castable refractories coj ntau qhov zoo, nrog rau kev txhim kho kev tiv thaiv thermal shocks, txhim kho lub zog tiv thaiv kev ntxhov siab thiab kev puas tsuaj, tshuaj inertness nyob rau hauv ib puag ncig hnyav, thiab txhim khu kev qha ntawm qhov kub siab. Nws yog ib qho tseem ceeb uas yuav tau txiav txim siab txog yam xws li kev faib khoom loj, qhov loj me, thiab cov ntawv thov tshwj xeeb thaum xaiv tabular alumina rau qhov kub thiab txias castable refractories los ua kom nws cov txiaj ntsig zoo hauv cov ntawv thov.

Tabular corundum muaj qhov ntxhib thiab tsim tau zoo -Al2O3 siv lead ua qauv. Cov ntsiab lus ntawm Al2O3 yog ntau tshaj 99.3 feem pua. Crystal-likestructure nrog me me pores thiab ntau kaw pores. Lub porosity yog roughly tib yam li cov fused corundum.
