Cov pob ceramic ua haujlwm ua cov khoom siv npog thiab lub pej thuam rau cov catalyst hauv lub reactor. Nws muaj cov yam ntxwv ntawm kev tiv taus kub thiab siab, nqus dej tsawg, thiab cov khoom siv tshuaj ruaj khov. Muaj peev xwm tiv taus xeb los ntawm cov kua qaub, alkalis, thiab lwm yam organic solvents, thiab tuaj yeem tiv taus kev hloov pauv kub uas tshwm sim thaum lub sijhawm tsim khoom. Nws lub luag haujlwm tseem ceeb yog ua kom qhov chaw faib roj lossis kua ntau ntxiv, txhawb nqa thiab tiv thaiv cov catalysts nquag nrog lub zog qis. Kev faib tawm ntawm cov pob ceramic: Cov pob ceramic tuaj yeem faib ua cov pob ceramic inert, cov pob ceramic thermal storage thiab cov pob ceramic sib tsoo raws li lawv lub hom phiaj.
Lub pob ceramic khaws cia cua sov muaj cov yam ntxwv ntawm qhov chaw du, tiv taus corrosion, muaj zog heev, thiab ua haujlwm zoo khaws cia cua sov, thiab yog ib qho khoom siv tshwj xeeb rau cov khoom siv khaws cia cua sov cais cua. Lawv txhua tus yog lub voos xwmfab, thiab cov pob ceramic khaws cia cua sov yog siv los khaws cia cua sov. Lawv tsim nyog rau kev ua kom cua sov hauv cov nroj tsuag hlau kom ua tiav qhov yuav tsum tau ua kom sov sai, thiab kuj siv rau cov qhov cub txhuas yaj forging, thiab lwm yam.
Cov pob zeb ceramic sib tsoo yog cov khoom siv sib tsoo uas siv rau cov khoom siv sib tsoo zoo xws li cov tshuab sib tsoo pob, cov tshuab sib tsoo kaus poom, thiab cov tshuab sib tsoo co. Cov pob zeb ceramic sib tsoo muaj qhov zoo xws li qhov nyuaj siab, qhov loj me me, thiab kev tiv thaiv corrosion. Lawv qhov kev ua haujlwm sib tsoo thiab kev tiv thaiv hnav zoo dua li cov pob zeb ib txwm lossis cov pob zeb ntuj, thiab siv dav hauv kev lag luam xws li ceramics, iav, enamel, pigments, thiab kev tsim kho tshuaj lom neeg.
Raws li cov ntsiab lus AL2O3 sib txawv, cov pob zeb sib tsoo ceramic raug muab faib ua cov pob zeb sib tsoo silicon carbide, cov pob zeb sib tsoo microcrystalline nruab nrab txhuas, thiab cov pob zeb sib tsoo txhuas siab. Feem ntau, cov pob uas muaj cov ntsiab lus txhuas ntawm 60-65% raug cais ua cov pob zeb txhuas nruab nrab, cov pob uas muaj cov ntsiab lus txhuas ntawm 75-80% raug cais ua cov pob zeb txhuas nruab nrab siab, thiab cov pob uas muaj cov ntsiab lus txhuas ntawm ntau dua 90% raug cais ua cov pob zeb txhuas siab. Cov pob alumina siab raug faib ua 90 porcelain, 92 porcelain, 95 porcelain, thiab 99 porcelain. Vim nws cov nqi tsim khoom siab heev, 99 porcelain tsis tshua muaj ntau los ntawm cov chaw tsim khoom loj, thiab tam sim no feem ntau tsim los ntawm tes los ntawm qee lub Hoobkas tshwj xeeb ceramic.
