Yog vim li cas vim li cas refractory bricks yog "hluav taws-resistant" feem ntau yog vim lawv cov khoom tsim tshwj xeeb thiab tsim, uas muaj cov yam ntxwv hauv qab no:
Cov ntaub ntawv kub resistant: Refractory bricks feem ntau yog ua los ntawm cov ntaub ntawv kub, xws li alumina, aluminium silicate, magnesium silicate, thiab lwm yam. Cov ntaub ntawv no muaj cov ntsiab lus melting siab thiab tuaj yeem tswj cov qauv kev ruaj ntseg ntawm qhov kub siab heev yam tsis muaj softening lossis melting.
Qhov ceev ntawm cov hluav taws kub refractory cib: Refractory cib feem ntau yog tsim los ntawm cov khoom siv ceramic, uas pab tiv thaiv kev kub nyhiab. Cov khoom siv high-density tuaj yeem ua kom qeeb ntawm kev ua kom sov, yog li txo qhov kub ntawm lub cib saum npoo thiab tswj kev ruaj ntseg ntawm cov qauv.
Resistant mus rau high-kub expansion: Cov txheej txheem ntawm refractory bricks feem ntau suav nrog precisely tswj sintering, uas yuav pab tau kom paub tseeb tias cov bricks muaj ib tug tsawg coefficient ntawm thermal expansion ntawm high kub. Qhov qis coefficient ntawm thermal expansion txhais tau hais tias refractory bricks tsis tshua muaj kev hloov pauv loj nyob rau hauv qhov kub thiab txias, txo qhov kev pheej hmoo ntawm thermal stress thiab breakage.
Corrosion resistance: Cov khoom ntawm refractory bricks feem ntau muaj kev tiv thaiv siab rau tshuaj corrosion. Qhov no ua rau lawv haum rau siv nyob rau hauv qhov kub thiab txias qhov chaw uas muaj acids, alkalis los yog lwm yam corrosive tshuaj tej zaum yuav tshwm sim.
Nyob rau hauv cov ntsiab lus, refractory cib tuaj yeem tiv taus qhov kub thiab txias vim tias lawv cov qauv tsim thiab cov khoom xaiv muab lawv zoo heev kub stability, corrosion kuj, thermal conductivity thiab thermal expansion zog, tso cai rau lawv tswj lawv cov kev ntseeg siab thiab thermal expansion nyob rau hauv huab cua kub. kev ua tau zoo. Qhov no ua rau lawv muaj txiaj ntsig zoo hauv cov ntawv thov xws li cov khoom siv hluav taws xob, cov khoom siv kub kub thiab cov cub tawg.
