Cov lim dej ceramic ua haujlwm raws li lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm capillary thiab micropore, siv microporous ceramics ua cov lim nruab nrab, siv ntau qhov nqaim microporous ceramics, thiab cov khoom sib cais cov kua-kua tsim raws li txoj cai capillary.Lub disc lim hauv lub xeev tsis zoo siab ua haujlwm siv cov dej tshwj xeeb thiab huab cua nruj cov yam ntxwv ntawm microporous ceramic lim phaj kom tshem tawm lub tshuab nqus tsev nyob rau hauv cov kab noj hniav sab hauv ntawm ceramic lim phaj thiab tsim kom muaj qhov sib txawv siab nrog rau sab nraud, cov ntaub ntawv tshem tawm hauv lub chute yog adsorbed rau ntawm ceramic lim phaj nyob rau hauv qhov kev txiav txim siab tsis zoo.Cov khoom siv tsis tuaj yeem cuam tshuam rau saum npoo ntawm cov phaj ceramic los ntawm microporous ceramic lim phaj, thaum cov kua tuaj yeem nkag mus rau hauv cov pa roj-kua faib khoom (nqus chim chim) rau sab nraud tawm lossis rov ua dua vim qhov cuam tshuam ntawm lub tshuab nqus tsev siab sib txawv thiab lub hydrophilicity ntawm ceramic lim phaj, thiaj li ua tiav lub hom phiaj ntawm cov khoom sib cais-kua.
Cov duab thiab cov txheej txheem ntawm cov lim dej ceramic zoo ib yam li lub hauv paus ntsiab lus ntawm kev ua haujlwm ntawm lub tshuab nqus tsev disc, uas yog, nyob rau hauv qhov kev txiav txim siab ntawm qhov sib txawv, thaum lub ncua kev kawm ntawv hla dhau lub lim nruab nrab, cov khoom yog cuam tshuam rau saum npoo ntawm qhov nruab nrab. tsim lub ncuav mog qab zib lim, thiab cov kua ntws tawm los ntawm cov lim nruab nrab kom ua tiav lub hom phiaj ntawm cov kua-kua sib cais.Qhov txawv yog tias cov lim nruab nrab ceramic lim phaj muaj cov micropores uas tsim cov nyhuv capillary, kom cov capillary quab yuam hauv micropores ntau dua li lub tshuab nqus tsev, kom cov micropores ib txwm muaj kua.Nyob rau txhua qhov xwm txheej, lub phaj lim dej ceramic tsis tso cai rau huab cua hla.Vim tias tsis muaj cua nkag mus, lub zog noj thaum lub sij hawm sib cais-kua yog tsawg thiab lub tshuab nqus tsev kawm ntawv siab.
