Porous ceramic ndi thupi lopanda zitsulo lomwe silinapangidwe ndi zitsulo lomwe lili ndi kuchuluka kwa voids.Kusiyana kwakukulu kuchokera kuzinthu zina zopanda zitsulo (zadothi zowuma) ndikuti zili ndi voids (pores) ndi kuchuluka kwa voids (pores) zomwe zili nazo.Malinga ndi njira yopangira ma pore ndi ma voids, zoumba za porous zingagawidwe kukhala: zoumba zokhala ndi thovu, zisa za uchi, ndi zoumba zazing'ono.
Chifukwa cha kuchuluka kwa pores, kapangidwe, katundu ndi ntchito za porous ceramics zasinthidwa kwambiri.Poyerekeza ndi zoumba zolimba, zoumba za porous zili ndi mikhalidwe isanu iyi:
1. Kachulukidwe kakang'ono kakang'ono komanso kulemera kopepuka.
2. Malo akuluakulu enieni apamwamba ndi ntchito yabwino yosefera.
3. Low matenthedwe madutsidwe, zabwino matenthedwe ndi mawu kutchinjiriza katundu.
4. Kukhazikika kwamankhwala ndi thupi, kumatha kutengera malo osiyanasiyana owononga, kumakhala ndi mphamvu zamakina komanso kuuma, komanso kukana kutentha.
5. Njirayi ndi yosavuta ndipo mtengo wake ndi wotsika.
1. Amagwiritsidwa ntchito pazida zosefera ndi zolekanitsa
Chipangizo chosefera chopangidwa ndi zinthu zooneka ngati mbale kapena za tubular za ceramic porous chili ndi mawonekedwe a malo akulu osefera komanso kusefa kwakukulu.Amagwiritsidwa ntchito kwambiri pakuyeretsa madzi, kulekana ndi kusefera kwamafuta, komanso kulekanitsa njira organic, njira za acid-base, zakumwa zina zowoneka bwino komanso mpweya wothinikizidwa, mpweya wa uvuni wa coke, nthunzi, methane, acetylene ndi mpweya wina.Chifukwa chakuti zoumba zadothi zimakhala ndi ubwino wokana kutentha kwambiri, kukana kuvala, kusagwira ntchito kwa mankhwala, ndi mphamvu zamakina apamwamba, zikuwonetseratu ubwino wake wapadera pakugwiritsa ntchito madzi owononga, madzi otentha kwambiri, ndi zitsulo zosungunuka.
2. Amagwiritsidwa ntchito pa chipangizo choyamwitsa komanso chochepetsera phokoso
Monga zinthu zotulutsa mawu, zoumba za porous zimagwiritsa ntchito ntchito yake yofalitsa, ndiko kuti, kufalitsa mpweya wotuluka chifukwa cha mafunde a phokoso kudzera mumtundu wa porous kuti akwaniritse cholinga cha kuyamwa kwa mawu.Ma ceramics a porous monga zida zotulutsa mawu zimafunikira kukula kwa pore (20-150 μm), porosity yapamwamba (pamwamba pa 60%) ndi mphamvu zamakina apamwamba.Zoumba za ceramic zakhala zikugwiritsidwa ntchito m'nyumba zazitali, ma tunnel, njanji zapansi panthaka ndi malo ena omwe ali ndi zofunika kwambiri zoteteza moto, komanso m'malo omwe ali ndi zofunikira zotchingira mawu kwambiri monga malo otumizira ma TV ndi ma sinema.
3. Ntchito mafakitale chothandizira chonyamulira
Popeza ma porous ceramics ali ndi mphamvu zotsatsa komanso ntchito yabwino, ataphimbidwa ndi chothandizira, kutembenuka mtima komanso kuchuluka kwa momwe amachitira kudzakhala bwino kwambiri pambuyo poti madziwo adutsa podutsa pobowo zadothi.Pakali pano, kafukufuku wa porous ceramics monga chothandizira ndi chothandizira kupatukana ndi nembanemba, chomwe chimaphatikiza kulekanitsa ndi kuchititsa katundu wa porous ceramic zipangizo, motero kumakhala ndi chiyembekezo chochuluka chogwiritsira ntchito.
4. Ikugwiritsidwa ntchito kuzinthu zamagetsi zamagetsi
Mfundo yogwira ntchito ya sensa ya chinyezi ndi sensa ya gasi ya sensa ya ceramic ndi yakuti pamene microporous ceramic imayikidwa mu mpweya kapena madzi, zigawo zina zapakati zimatengeka kapena zimakhudzidwa ndi thupi la porous, ndi kuthekera kapena panopa. microporous ceramic ndi nthawi ino.kusintha kuti azindikire kapangidwe ka gasi kapena madzi.Masensa a Ceramic ali ndi mawonekedwe a kukana kutentha kwambiri, kukana kwa dzimbiri, njira yosavuta yopangira, kuyesa tcheru komanso kolondola, ndi zina zambiri, ndipo amatha kukhala oyenera nthawi zambiri zapadera.
