Porous ceramic ndi kukana kutentha kwakukulu, mphamvu zambiri, kukhazikika kwa mankhwala

Porous ceramic zipangizo zosefera ndi kupatukana zipangizo

Chipangizo chosefera chomwe chimapangidwa ndi mbale ya porous ceramic kapena zinthu za tubular chili ndi mawonekedwe amdera lalikulu losefera komanso kusefera kwakukulu. Amagwiritsidwa ntchito kwambiri pakuyeretsa madzi, kulekanitsa mafuta ndi kusefera, yankho la organic, yankho la asidi ndi alkali, madzi ena a viscous ndi mpweya wothinikizidwa, mpweya wa uvuni wa coke, nthunzi, methane, acetylene ndi kupatukana kwina kwa gasi. Chifukwa ma porous ceramics ali ndi ubwino wotsutsa kutentha kwakukulu, kukana kuvala, kukana kwa mankhwala ndi mphamvu zamakina apamwamba, amasonyeza ubwino wawo wapadera mumadzi owononga, kutentha kwa madzi, zitsulo zosungunuka ndi zina zotero.

Zida za porous ceramic zomangira phokoso komanso zida zochepetsera phokoso

Monga mtundu wa zinthu zotulutsa mawu, zida za porous zimagwiritsa ntchito ntchito yake yofalitsa, ndiko kuti, kufalitsa mphamvu ya mpweya yomwe imayambitsidwa ndi mafunde a phokoso kudzera m'mapangidwe a porous, kuti akwaniritse cholinga cha kuyamwa kwa mawu. Monga zida zotulutsa mawu, zoumba za porous zimafunikira kabowo kakang'ono (20-150um), kutsika kwakukulu (kuposa 60%), ndi mphamvu zamakina apamwamba. Zojambula za ceramic zakhala zikugwiritsidwa ntchito kwambiri m'nyumba zokwera kwambiri, ma tunnel, njanji zapansi panthaka ndi malo ena omwe ali ndi zofunikira zotetezera moto, malo owonetsera kanema wawayilesi, malo owonetsera mafilimu ndi malo ena omwe ali ndi zofunikira zowonjezera phokoso.

Semiconductor vacuum adsorption

Chifukwa cha kutsatsa kwake kwabwino komanso ntchito yake, zoumba za porous ndi zida zosasinthika za vacuum adsorption komanso kusamutsa zowotcha za silicon mumayendedwe a semiconductor.

Zida za ceramic za porous zimagwiritsidwa ntchito pozindikira zinthu

Mfundo yogwira ntchito ya sensa ya chinyezi ndi sensa ya gasi ya sensa ya ceramic ndikuti pamene micro-porous ceramic imayikidwa mu gasi kapena sing'anga yamadzimadzi, zigawo zina zapakati zimapangidwira kapena zimakhudzidwa ndi thupi la porous, ndi zotheka kapena zamakono. a ceramic micro-porous ceramic idzasintha kuti izindikire momwe mpweya kapena madzi. Sensa ya Ceramic ili ndi mawonekedwe a kutentha kwambiri, kukana kwa dzimbiri, njira yosavuta yopangira, kuzindikira komanso kuzindikira molondola, ndipo ingagwiritsidwe ntchito nthawi zambiri zapadera.

Zinthu za diaphragm zimatengedwa ndi porous ceramic zakuthupi.

Ceramic porous imakhala ndi malo akuluakulu okhudzana ndi madzi ndi gasi, ndipo mphamvu ya batri ndiyotsika kwambiri kuposa ya zipangizo wamba. Chifukwa chake, kugwiritsa ntchito ma porous ceramics mu zida za electrolytic diaphragm kumatha kuchepetsa mphamvu ya batri, kuwongolera magwiridwe antchito a electrolytic, ndikupulumutsa mphamvu zamagetsi ndi zida zamagetsi. Ma porous ceramic nembanemba amagwiritsidwa ntchito m'maselo amafuta, ma cell amafuta ndi ma cell a photochemical.

Zida za porous ceramic pazida zogawa mpweya

Mpweya umawombedwa kukhala ufa wolimba kudzera mu porous ceramic zakuthupi, zomwe zingapangitse ufawo kukhala wotayirira komanso wamadzimadzi, kukwaniritsa kutentha kwachangu, kutengerapo kutentha kwa yunifolomu, kufulumizitsa momwe zimakhalira, ndikuletsa ufawo kuti usagwedezeke. Ndi yoyenera kunyamula ufa, kutentha, kuyanika ndi kuziziritsa, makamaka simenti, laimu, opanga ufa wa aluminiyamu ndi kayendedwe ka ufa.

Kutentha-kuteteza porous ceramics

Zoumba za ceramic zimakhala ndi ubwino wokhala ndi porosity kwambiri, kachulukidwe kakang'ono, kutsika kwa matenthedwe, kukana kwakukulu kwa kutentha, kutentha kwazing'ono ndipo zakhala zikhalidwe zotentha. Zida zapamwamba za porous ceramic zimatha kutentha kuti zigwiritsidwe ntchito ngati chipolopolo cha spacecraft ndi missile head ... etc.

Porous ceramic zida za biomedical ntchito

Porous bioceramics amapangidwa pamaziko a bioceramics achikhalidwe, okhala ndi biocompatibility yabwino, zinthu zokhazikika zakuthupi ndi zamankhwala komanso zotsatirapo zopanda poizoni, ndipo akhala akugwiritsidwa ntchito kwambiri m'munda wa zamankhwala. Zoyika za mano ndi zina zopangidwa ndi zoumba zadothi zakhala zikugwiritsidwa ntchito pachipatala.
