I-ceramic enePorous yi-inorganic non-metallic powder sintered body enomlinganiselo othile we-voids.Umahluko osisiseko kwezinye i-inorganic non-metallic (i-ceramics eshinyeneyo) kukuba ingaba iqulethe i-voids (iipore) kwaye yintoni ipesenti yomthamo we-voids (iipore) equletheyo.Ngokwendlela yokwenza i-pore-forming kunye ne-voids, i-ceramics ene-porous inokwahlulwa ibe: i-ceramics enegwebu, i-honeycomb ceramics, kunye ne-granular ceramics.
Ngenxa yobukho bexabiso elithile le-pores, isakhiwo, iipropati kunye nemisebenzi ye-ceramics ene-porous itshintshiwe kakhulu.Xa kuthelekiswa neeseramics ezishinyeneyo, iiseramics ezinamaqhekeza zinezi mpawu zintlanu zilandelayo:
1. Ubuninzi obuncinci kunye nobunzima obulula.
2. Indawo enkulu yendawo ethile kunye nomsebenzi olungileyo wokucoca.
3. I-conductivity ephantsi ye-thermal, i-thermal efanelekileyo kunye ne-sound insulation properties.
4. Iikhemikhali ezilungileyo kunye nokuzinza komzimba, ziyakwazi ukuziqhelanisa neendawo ezonakalisayo ezahlukahlukeneyo, zinamandla omatshini kunye nokuqina, kunye nokumelana nokushisa okulungileyo.
5. Inkqubo ilula kwaye ixabiso liphantsi.
1. Ifakwe kwizixhobo zokuhluza kunye nokwahlula
Isixhobo sokucoca esakhiwe ngeplate-shaped okanye iimveliso ze-tubular ze-ceramics ezinama-porous zineempawu zendawo enkulu yokucoca kunye nokusebenza okuphezulu kokucoca.Isetyenziselwa kakhulu ukucocwa kwamanzi, ukwahlula kunye nokuhluzwa kweoli, kunye nokwahlula izisombululo ze-organic, izisombululo ze-acid-base, ezinye i-viscous liquids kunye nomoya ocinezelweyo, igesi ye-oven coke, i-steam, i-methane, i-acetylene kunye nezinye iigesi.Ngenxa yokuba iiseramics ezinamathambo zineengenelo zokuxhathisa ubushushu obuphezulu, ukuxhathisa ukunxitywa, ukuxhathisa ukubola kweekhemikhali, kunye namandla aphezulu omatshini, ziya zikhula ngokubonisa iingenelo zazo ezizodwa kwiindawo zokusebenzisa ulwelo oludlekayo, ulwelo oluphezulu lobushushu kunye nezinyithi ezinyibilikisiweyo.
2. Isetyenziselwa ukufunxa isandi kunye nesixhobo sokunciphisa ingxolo
Njengesixhobo sokufunxa isandi, iikeramics ezinabileyo zisebenzisa ubukhulu becala umsebenzi wayo wokusasaza, oko kukuthi, ukusasaza uxinzelelo lomoya obangelwa ngamaza omsindo ngesakhiwo se-porous ukufezekisa injongo yokufunxa isandi.I-ceramics ene-porous njengezinto ezithatha isandi zifuna ubungakanani obuncinci be-pore (20-150 μm), i-porosity ephezulu (ngaphezu kwe-60%) kunye namandla aphezulu omatshini.Iikeramics ezinamanzi ngoku zisetyenzisiwe kwizakhiwo eziphakamileyo, iitonela, i-subways kunye nezinye iindawo ezineemfuno eziphakamileyo zokukhusela umlilo, kunye nakwiindawo ezineemfuno eziphezulu zokugquma isandi ezifana namaziko osasazo lweTV kunye nemiboniso bhanyabhanya.
3. Ifakwe kwi-industrial catalyst carrier
Ekubeni i-ceramics ene-porous inomthamo omhle we-adsorption kunye nomsebenzi, emva kokugqunywa nge-catalyst, ukuguqulwa kokusebenza kunye nesantya sokuphendula kuya kuphuculwa kakhulu emva kokuba i-reaction fluid idlula kwi-pores ye-porous ceramics.Okwangoku, ugxininiso lophando lwe-porous ceramics njengenkxaso ye-catalyst yi-inorganic separation catalytic membrane, edibanisa ukwahlula kunye neempawu ze-catalytic ze-porous ceramic materials, kwaye ngaloo ndlela inoluhlu olubanzi lwamathemba okusebenza.
4. Isetyenziswa kumalungu anovakalelo e-elektroniki
Umgaqo wokusebenza wenzwa yokufuma kunye negesi yesivamvo senzwa ye-ceramic kukuba xa i-ceramic microporous ibekwe kwigesi okanye i-medium medium, amanye amacandelo aphakathi adsorbed okanye aphendulwa ngumzimba we-porous, kunye namandla okanye okwangoku. i-ceramic microporous ngeli xesha.utshintsho lokubona ukubunjwa kwegesi okanye ulwelo.Izinzwa zeCeramic zineempawu zokumelana nokushisa okuphezulu, ukuxhathisa ukubola, inkqubo yokuvelisa elula, uvavanyo olubucayi kunye noluchanekileyo, njl., kwaye lunokufaneleka kwiimeko ezininzi ezikhethekileyo.
