I-Porous Ceramic iwumzimba ongaphili owenziwe ngempushana ongenayo i-metallic oqukethe inani elithile le-voids.Umehluko obalulekile kwezinye izinto ezingaphili ezingezona ezensimbi (izimbotshana zobumba eziminyene) ukuthi ingabe iqukethe ama-void (izimbotshana) kanye nephesenti levolumu ye-void (izimbotshana) equkethe.Ngokwendlela yokwenza izimbotshana nama-voids, izitsha zobumba ezinezimbotshana zingahlukaniswa zibe: izitsha zobumba ezinegwebu, izitsha zobumba zamakhekheba ezinyosi, nezitsha zobumba eziyimbudumbudu.
Ngenxa yokuba khona kwenani elithile lama-pores, isakhiwo, izakhiwo kanye nemisebenzi ye-ceramics ene-porous ishintshwe kakhulu.Uma kuqhathaniswa nezitsha zobumba eziminyene, izitsha zobumba ezinama-porous zinezici ezinhlanu ezilandelayo:
1. Ukuminyana kwenqwaba encane nesisindo esincane.
2. Indawo ethize enkulu kanye nomsebenzi omuhle wokuhlunga.
3. I-conductivity ephansi ye-thermal, izakhiwo ezinhle zokushisa ezishisayo nomsindo.
4. Ukuzinza okuhle kwamakhemikhali nokomzimba, kungakwazi ukuzivumelanisa nezimo ezihlukahlukene ezonakalisayo, kunamandla amahle emishini nokuqina, nokumelana nokushisa okuhle.
5. Inqubo ilula futhi izindleko ziphansi.
1. Kufakwe kumadivayisi okuhlunga nawokuhlukanisa
Idivayisi yokuhlunga eyakhiwe ngemikhiqizo emise okwepuleti noma ye-tubular ye-porous ceramics inezici zendawo enkulu yokuhlunga nokusebenza kahle kokuhlunga.Isetshenziswa kabanzi ekuhlanzeni amanzi, ukuhlukaniswa nokuhlunga uwoyela, kanye nokuhlukaniswa kwezixazululo eziphilayo, izixazululo ze-acid-base, ezinye uketshezi olubonakalayo nomoya ocindezelwe, igesi ye-coke kuhhavini, umusi, i-methane, i-acetylene namanye amagesi.Ngenxa yokuthi izimbotshana zobumba ezinezimbotshana zobumba zinezinzuzo zokumelana nezinga lokushisa eliphezulu, ukumelana nokuguga, ukumelana nokugqwala kwamakhemikhali, namandla amakhulu emishini, ziya ngokuya zikhombisa izinzuzo zazo eziyingqayizivele emikhakheni yokusetshenziswa koketshezi olubolayo, uketshezi olushisa kakhulu, nezinsimbi ezincibilikisiwe.
2. Kusetshenziswa kudivayisi yokumunca nokunciphisa umsindo
Njengempahla emunca umsindo, izitsha ze-ceramics ezinezimbobo ngokuyinhloko zisebenzisa umsebenzi wazo wokusabalalisa, okungukuthi, ukuhlakaza ukucindezela komoya okubangelwa amaza omsindo ngesakhiwo esinezimbotshana ukuze kufezwe injongo yokumunca umsindo.I-ceramics enezimbotshana njengezinto ezimunca umsindo zidinga usayizi omncane wembotshana (20-150 μm), i-porosity ephezulu (ngaphezu kuka-60%) kanye namandla aphezulu emishini.Izitsha ze-ceramics ezinama-porous manje sezisetshenziswe ezakhiweni eziphakeme kakhulu, imigudu, imigwaqo engaphansi komhlaba nezinye izindawo ezinezidingo zokuvikela umlilo eziphakeme kakhulu, kanye nasezindaweni ezinezidingo eziphakeme zokuvala umsindo ezifana nezikhungo zokusakaza ze-TV namasinema.
3. Kufakwe kusithwali se-industrial catalyst
Njengoba izitsha zobumba ezinezimbotshana zinamandla okukhangisa nomsebenzi omuhle, ngemva kokumbozwa nge-catalyst, ukusebenza kahle kokuguqulwa kanye nezinga lokusabela kuzothuthukiswa kakhulu ngemva kokuba uketshezi olusabelayo ludlule ezimbotsheni ze-ceramics enezimbotshana.Njengamanje, okugxilwe kukho kocwaningo lwe-porous ceramics njengoba i-catalyst isekela ulwelwesi lwe-inorganic separation catalytic, oluhlanganisa ukuhlukanisa kanye nezakhiwo ze-catalytic ze-porous ceramic materials, futhi ngaleyo ndlela inezinhlobonhlobo zamathemba okusebenza.
4. Kusetshenziswa ezingxenyeni ze-elekthronikhi ezibucayi
Umgomo wokusebenza wenzwa yomswakama kanye nenzwa yegesi yenzwa ye-ceramic ukuthi uma i-ceramic encane ifakwa endaweni yegesi noma uketshezi, ezinye izingxenye eziphakathi nendawo ziyakhangiswa noma ziphendulwa umzimba onezimbotshana, kanye namandla noma amandla i-ceramic microporous ikulesi sikhathi.izinguquko zokuthola ukwakheka kwegesi noma uketshezi.Izinzwa ze-Ceramic zinezici zokumelana nokushisa okuphezulu, ukumelana nokugqwala, inqubo yokukhiqiza elula, ukuhlola okubucayi nokunembile, njll., futhi kungafaneleka izikhathi eziningi ezikhethekile.
