Brickare siv nyob rau hauv ntau yam khoom siv cua sov rau kev tsim kho qhov cub qhov cub siab thiab cov kab hluav taws xob refractory kab. Ntev npaum li kev pab cuam lub neej ntawm cov khoom lag luam, kev siv cov pob zeb refractory cib muaj ntau dua thiab ntau dua, thiab cov xeb ntawm refractory cib tsis kam yog qhov taw qhia tseem ceeb heev rau kev txiav txim siab ntawm kev siv tshuaj lom neeg thiab kev siv tshuab coj thiab tsim kua muag ntawm cov cib tsis kam. Nws yog qhov tseem ceeb rau kev txiav txim siab xaiv qhov tsim nyog ntawm cov av ntsa refractory hauv cov txheej txheem tsim tawm kom raug.
Cov xwm txheej cuam tshuam qhov kev tiv thaiv ntawm kev yaig ntawm cov ntoo refractory yog yam sab hauv thiab sab nraud yam. Sab hauv cov khoom suav nrog: tshuaj lom neeg muaj pes tsawg leeg thiab cov ntxhia pob zeb sib xyaw nrog refractory cib, cov qauv thiab lwm yam khoom ntawm refractory cib; lwm yam sab nraud: cov khoom ntawm erosive media.
Cov xwm txheej ntawm kev siv (kub, nias, thiab lwm yam) thiab kev sib cuam tshuam ntawm erosive media nrog refractory cib.
Cov tshuaj lom neeg thiab tshuaj ntxhia muaj pes tsawg leeg ntawm refractory cib. Cov tshuaj lom neeg sib txawv muaj ntau cov tshuaj tiv thaiv corrosion rau cov khoom siv. Acidic refractory cib muaj qhov zoo corrosion tsis kam rau acid etching media, thaum acid corrosion media ntawm alkaline cib muaj cov tsis muaj zog corrosion.
Lub refractory cib yog cov khoom sib txuam ntau theem sib xyaw ua ke ntawm ib qho loj crystalline theem thiab sib nqus. Lub ntsiab crystalline theem muaj qhov siab dua hauv refractoriness, loj hauv qhov loj me, thiab tiv taus xeb los ntawm kev thaj tsam me me. Nws yog qhov yooj yim yog tias matrix muaj qib siab ntawm impurities. Sib sau ua kua theem. Yog tias theem ua kua tau tsim qis, qhov kev tiv thaiv ntawm kev yaig ntawm cov khoom yog qhov tsis zoo.
Tus qauv ntawm refractory cib; nws feem ntau hais txog qhov loj me thiab naj npawb ntawm refractory cib, kev faib khoom thiab kev koom ua ke ntawm txhua qhov khoom, cov duab thiab kev faib tawm ntawm stomata.
Lwm cov khoom muaj zog ntawm cov qib refractory cib: ntau ntom ntom nti, plooj plhaw, thermal poob siab tsis kam, oxidation tsis kam thiab siab kub ntim ruaj ntseg ntawm refractory cib muaj qhov cuam tshuam zoo ntawm kev ua xeb ntawm cov cib tsis kam. Ua haujlwm siab dua thiab tsis tshua muaj porosity Cov khoom siv kuj xoob ntawm cov khoom ntom ntom tau zoo corrosion thiab thermal shock tsis kam; thaum cov khoom raug rau thermal poob siab, tawg lossis tawg tuaj yeem tshwm sim, yog li ua rau lub nruab nrab etching nkag mus rau hauv cov khoom, uas ua rau txo qis ntawm kev txhim kho corrosion.
