Iyo yakakosha zvinhu uye chimiro chehuchi ceramic sefa inosarudza maitiro ayo. Kutanga, ine simba rakanaka, kupfeka uye kusagadzikana kwemarara, uye hupenyu hurefu hwebasa. Panguva imwecheteyo, nekuda kwesimba rayo rakanaka, hapana deformation ye micropores, uye yakagadzikana zviratidzo zvekugadzira pasina kuchinja; Iyo pores idiki (inenge 1.5 microns), iyo capillary chiito chakasimba, uye iyo filtrate inongoyamwa mumamicropores. Basa repombi yevacuum ndeyekuburitsa iyo filtrate kuchengetedza simba; (kusvika 0.098Mpa) sefa keke mwando yakaderera, uye iyo sefa yekushandisa coefficient yakakwira; zvakare nekuda kwediki pores, iyo yakaturikwa yakasimba yemukati mune filtrate yakaderera, uye iyo filtrate yakajeka, iyo inogona kushandiswa pane-saiti kutenderera kwemvura kudzivirira kusvibiswa kwezvakatipoteredza uye kuchengetedza zviwanikwa zvemvura.
